1 Introduction

For many people like me who like to collect film and television resources,Emby It is almost the only choice for a home media center: it has a beautiful interface, clear categories, and rich functions, which can turn local resources into a streaming media experience in seconds.

But when the collection size grows to thousands or tens of thousands of titles, you will find that Emby's work at the bottom level - that is,Media file scraping and metadata organization——In fact, it is not the area it is best at.

Emby was designed for display and playback, not batch management. It can help you transform your organized media library into a beautiful interface, but only if your files are properly named, clearly structured, and complete. Otherwise, it'll frequently encounter frustrating issues like recognition errors, mismatched covers, garbled metadata, incorrectly merged videos, and incredibly slow scanning.

This problem is magnified exponentially when the total number of movies exceeds 5,000. The first scan of the media library often takes ten hours or even longer, and any small problem in the naming, path, or nfo file during the process can cause Emby to misidentify, miss, or even merge hundreds of movies into a single entry.

in other words,Emby is more like a "presentation layer" rather than a "data cleaning layer".

Therefore, if there is a more professional tool to help Emby complete the initialization and organization of the media library in advance, allowing Emby to focus on its main job of "playback and display" - then the efficiency and stability of the entire system will be improved to a higher level.

Of all the solutions I've tried, the one that satisfies me the most is the one I've ignored for so many years:TinyMediaManager(TMM).

TMM can complete the low-level and tedious organization work for you before Emby intervenes - automatic naming, downloading posters, matching metadata, generating nfo files, proofreading actor information, unifying folder structure... so that all media files are "pre-processed" in a standardized format and then handed over to Emby for display.

This will not only greatly reduce the scanning burden of Emby, but also greatly improve the recognition accuracy and overall performance.Emby's best partner: One is responsible for initializing and organizing the world, and the other is responsible for making the world look good.

2 Starting with Scraping – The Real Advantages of TMM

2.1 Overview

Scraping may seem like a simple "pull down movie information" operation, but when scaling to thousands or even tens of thousands of titles, it directly impacts the efficiency and stability of the entire media management process. This chapter begins with an explanation of the nature of scraping and, using my own practical experience, compares the performance and applicability of Emby and TinyMediaManager (TMM) for large-scale repositories.

2.2 What is Scraping?

definition:Scraping means that the software automatically obtains the metadata of movies or TV series from the Internet - including title, year, director, actors, plot summary, poster, background image, IMDb/TMDb ID, etc. - and writes this information into a local file or database so that the media server can correctly identify and display it.

A typical scraping process includes:

1. Scan files (identify title, year, version information from file names);
2. Matching databases (search entries in TMDb/IMDb/TheTVDB);
3. Crawl metadata (download plot, actors, ratings, pictures, etc.);
4. Generate local files (.nfo, poster.jpg, fanart.jpg, etc.), which are the final products of scraping and are used by the media server as a basis for identification.

Scraping itself is lightweight and negligible for small media libraries, but when the collection reaches thousands or tens of thousands of titles, every step of scraping becomes magnified: network requests surge, the probability of matching failures increases, the cost of error correction becomes high, and the cost of rescanning becomes expensive. Take my actual test as an example: I let Emby scan a library of about 10,000 "European and American movies". A complete scan + matching + downloading of metadata often takes 10 minutes. Ten to twenty hours or more; Once an identification error or network problem occurs, the entire process may be forced to be rerun, which is very time-consuming.

At the same scale, TMM's scraping experience is often much faster.Mainly local batch processing, has greater control over directories and naming conventions, and can do most of the work in the "pre-processing" stage, freeing media servers (such as Emby) from time-consuming scraping tasks.

2.3 nfo file: the end of scraping and the starting point of the media library

2.3.1 Overview

In the entire scraping process, the .nfo file is a very critical link. It records all theText metadata——Includes title, year, director, actors, plot summary, genre, rating, and IDs of databases such as IMDb/TMDb.

From the perspective of scraping tools (such as TMM),Generating nfo is the final result of scraping; From the perspective of a media server (such as Emby, Jellyfin or Plex),Reading nfo is the starting point for identifying the video.

2.3.2 How does nfo work?

When you finish scraping with TMM, there will usually be a set of files in each movie directory:

movie.nfo poster.jpg fanart.jpg  

The .nfo file contains detailed information about the film; poster.jpg and fanart.jpg correspond to the poster and background, respectively. Later, when you instruct Emby to scan your library, it won't blindly re-scrape the file from the internet, but will prioritize reading these local files. As long as these metadata files are complete, Emby can directly identify the film's key information and automatically categorize it into the corresponding movie entry.

In other words, TMM is responsible for scraping and generating nfo files, while Emby is responsible for reading the output. The relationship between the two is more like "front-end acquisition and editing + back-end presentation": the former prepares the data, while the latter simply displays it. If files such as posters and backgrounds have already been downloaded locally, Emby can scan and generate the entire interface content without any internet connection.

2.3.3 TMM Free Version vs. Pro Version: Differences and Practical Impact

Although the core logic of scraping is the same between TMM Free and Pro, the difference in experience between the two is very obvious in large-scale media libraries (especially thousands to tens of thousands of videos), especially inImage quality, automation, and reusabilityOn these three points.

Function items	Free version (Basic)	Pro version
Number of scraping sources	Mainly supports TMDb / TVDb	More data sources can be added and priorities can be customized
Image quality	Standard resolution (approximately 1000px)	Native resolution (4K/UHD)
Automation capabilities	Manual batch processing, manual selection required	Support automatic updates, scheduled tasks, and incremental recognition
Actor photos and stills	Often missing or low resolution	Complete actor portraits, logos, banners, etc.
stability	Easy to trigger TMDb current limiting	Multi-threading + API Key management, faster and more stable
Applicable scenarios	Small personal collection (hundreds to thousands of titles)	Medium to large media libraries (tens of thousands of titles, offline use scenarios)

For Emby, this difference is directly reflected in:

• The .nfo file generated by the free version is sufficient for Emby to recognize the movie information, but it may still need to connect to the Internet to pull high-definition images;
• The Pro version can download all images at once during the scraping stage.Achieve true offline display.

2.3.4 Network Adaptation and Scientific Access Issues

In actual use, scraping not only tests the functionality of the software itself, but is also often restricted by the network environment.

For example, if Emby's built-in TMDb plugin is installed directly on a NAS, the NAS must be able to access external resources like TMDb/IMDb to perform online scraping. This means that if the NAS lacks global scientific capabilities, simply modifying the hosts file is often insufficient to prevent network contamination or restricted access. When scanning a media library of tens of thousands of titles, request failures, timeouts, or incomplete data are likely to occur.

In contrast, TMM's offline scraping mode has obvious advantages in this scenario:

• All scraping work is performed on the computer side, which only requires that the computer can access the network normally;
• After scraping, the generated .nfo file and local cover image can be placed directly on the NAS, and there is no need to connect to the Internet again when Emby scans;
• This way, you don't have to worry about configuring the global science for the NAS network environment, and you can still ensure the metadata integrity and presentation effect of large-scale media libraries.

In other words, the design of TMMShifting network dependencies from the server to the clientThis greatly reduces the complexity and potential risks of managing large-scale media libraries. This is a very practical advantage for those who have large collections and want long-term stable operation of the NAS.

3 TMM installation and basic settings

3.1 TMM Installation

The installation of TMM is very simple, just download it from the official website:https://www.tinymediamanager.org/download/Select the deployment method that suits your operating environment:

My work machine is a Mac Mini with M4Pro, so I chose the aarch64 dmg file for installation.

3.2 TMM Basic Settings

As I mentioned in Section 2.3.3, TMM is divided into free and PRO versions. However, for cooperation with Emby, the functions of the free version are actually sufficient, and there is no need to do too much settings (the default configuration is fine).

After opening the TMM main interface, click the "Settings" button in the lower left corner to enter the settings interface:

You can see that there are 4 major categories of options: general options, movies, series movies, and TV shows:

1. General options

General OptionsThis section primarily defines TMM's basic operating environment and global behavior. It determines the software's language interface, file naming conventions, log and cache locations, proxy and network access methods, and compatibility with external players or media servers. Simply put, these options don't directly affect the scraping results themselves, but they lay the foundation for TMM's underlying operational specifications—such as path formats, network access capabilities, and program stability. Proper configuration ensures smoother scraping, exporting, and synchronization processes.

For example, in "External Tools" you can define an external player for playing videos in TMM:

In "System", you can specify the memory size that TMM can use (I had too many movies, and the default 512 was directly stuck. I later adjusted it to 4096) and the address of the external scientific proxy server:

2. Movies and film series

MovieOptions are one of the two most core sections of TMM, specifically controlling the detailed behavior of movie scraping. These determine how TMM identifies movie files, which databases it retrieves metadata from (such as TMDb, IMDb, Fanart.tv, etc.), what types of images it downloads (posters, backgrounds, actor images, etc.), and the format and naming of the generated nfo files. Simply put, these settings directly affect the accuracy and completeness of scraping—with proper configuration, TMM can generate clean, standardized local metadata in a single scan that is fully compatible with media servers like Emby.

For the free version of TMM, there are not many options to set in this section. Just use the default values. The only thing you need to set is the "Media Library Directory":

And NFO settings:

For metadata scraping sources, the free version can only use TMDB, but then again, TMDB is enough:

As for the third categoryfilm seriesThis option is primarily used to manage and beautify "Movie Sets," which are groups of films like "The Lord of the Rings Trilogy" and "The Avengers." It doesn't scrape individual film information, but instead relies on the settings of the "Movies" module to automatically match series artwork (such as set covers and background images) from the same source and perform necessary post-processing. Simply put, this type of option is more inclined towards visual and structural optimization rather than data scraping. There's not much to say, so I won't go into detail; just look at the screenshots to understand:

3. TV programs

TV showsOptions are used to control TMM's scraping logic when processing drama resources (including American dramas, Japanese dramas, anime, etc.). Similar to the "Movie" module, it is responsible for obtaining drama metadata from designated databases (such as TheTVDB, TMDb TV, etc.) and generating corresponding files such as nfo, season posters, and single episode thumbnails. The difference is that the directory structure of dramas is more complex (title → season → episode), so this type of setting also involves drama naming rules, season number identification methods, and multilingual metadata matching strategies. After proper configuration, TMM can automatically sort out the drama hierarchy and generate a complete local database structure compatible with the media server.

Similar to the settings of the "Movie" module, the free version of TMM basically only needs to set the "Media Library Directory" and "NFO Settings":

For metadata scraping sources, the free version also only supports TMDB:

Of course, that's enough.

4. Introduction to the TMM main interface

4.1 "Movie" module

4.1.1 Overview

On the main interface of TMM, "Movies" is the core and most frequently used functional area. Most users interact with it, accounting for almost 80% of the total software usage time.

This is responsible for managing the metadata of all independent films, from identification, scraping, naming to cover downloading and NFO file generation, all done in this column.

In other words, if TMM is compared to a library management system, then "Movies" is the largest and busiest reading room. Here you can view the complete movie list, search information, update scraping results, and even perform batch operations on files.

There are 4 function drop-down menus in this interface: Update Media Library, Search & Scrape, Edit, Rename & Organize:

4.1.2 Update Media Library

The "Update Library" drop-down menu is used to manage and refresh your movie library within TMM. From here, you can add new library catalogs, update the entire library or specific libraries, or update metadata for individual movies. It also helps you find missing movies across all your libraries or manually create new offline movie entries.

It is worth noting that when you execute "Update All Media Catalogs", TMM will not only scan for file changes, but alsoAutomatically identify and scrape metadata for newly added videos(If the automatic scraping option is enabled). In other words, this step is actually aBatch, automatically triggered scraping process, which is very suitable for synchronizing the entire library after adding a large number of videos.

In general, this functional area is A control center that keeps your movie library consistent with the actual files and metadata up to dateFor daily maintenance and regular synchronization of new films, it is almost an essential step:

For example, after adding a new movie, you only need to click the "Update All Media Library Catalogs" at the top to scan the new resources and automatically scrape them.

4.1.3 Search & Scraping

“Search & Scrape” is one of the core functions of TMM, used toManually scrape a single movie or a small number of movies for precise processingThrough this menu, you can re-search and download metadata for the selected movie on the Internet, including the title, year, director, actors, plot summary, posters and background images.

This feature is particularly suitable for correcting recognition errors during automatic scraping, selecting different scraping sources, or supplementing newly added videos that were not automatically recognized.

Combined with the aforementioned "Update Media Library" (batch, automatically triggered scraping), it can ensure that your movie library is bothEfficient and automatic, and can be carried out when necessaryManual fine control, maintain the integrity of the data and the visual display effect:

Note: In daily use, when you add new movies to the media catalog, you usually only need to scan the corresponding catalog through "Update Media Library" (lazy people can directly update all catalogs), and TMM will automatically identify and scrape the metadata of the newly added movies, including posters, background images and detailed information."Search & Scrape" is mainly used to correct automatic scraping errors or to accurately match specific videosTherefore, if the newly added video is scraped normally, there is generally no need to manually enter this function.

4.1.4 Edit

The "Edit" function allows users to manually modify the metadata of a single movie or multiple movies. This includes information such as the title, year, director, actors, tags, ratings, as well as adjustments to the cover and background image.

The purpose of this function is to Make up for omissions or errors that may occur in automatic scraping, allowing you to precisely control movie data based on actual conditions, thereby maintaining the integrity and standardization of the entire movie library:

Note: The "Edit" function is similar to "Search & Scrape" and is mainly used to manually fine-tune or correct the automatic scraping results. It is usually not needed for daily new videos and batch scanning.

4.1.5 Rename & Organize

The "Rename & Organize" feature unifies movie file and folder names according to user-defined naming conventions and directory rules, and organizes movies into designated directories. This convention can be one of TMM's built-in naming templates or a custom format, such as "Movie Title (Year)" as a folder name, and "Movie Title (Year) - Resolution.ext" as a file name.

This way, the file system remains clean, naming is consistent, and metadata from media servers (such as Emby, Jellyfin) is kept consistent, allowingThe storage management of massive movies is more organized, making it easier to find, synchronize and back up:

Note: This feature will directly modify the names of files and folders, so if you absolutely must do this, it's recommended to back up your files beforehand. I personally prefer to name and rename files at the time of downloading to avoid the risks of subsequent batch operations, and only use it as a fire-fighting or special case measure.

4.2 Film series

The "Series" section is specifically designed for managing film series with multiple sequels or related titles. Unlike individual films, you can centrally manage all the titles in the same series here, keeping metadata, cover art, descriptions, and other information consistent.

The four main operations in this function area are very intuitive: First, you can "New Film Series" Create a new series entry; the remaining three functions (update series, edit series information, delete series) are all single-button operations without complicated drop-down menus.

In general, this module mainly solves Organization and management issues of serialized content, so that multiple related movies can be neatly categorized in TMM and displayed consistently in the media server:

4.3 Television Programs

The "TV Shows" function area is similar to the "Movies" function area and is also divided into 4 drop-down menus:Update media library, search & scrape, edit, rename & organize. However, the objects managed here are TV series, single episodes, and animated series.

With this module, you can add or update your media library catalog, scrape individual episodes or entire seasons, manually edit metadata, and uniformly rename and organize file structures.

This module's functional logic and operation are consistent with the movie module, making episode management equally efficient and neat, and keeping data synchronized with the media server. Since I've already talked about it in the movie module, I won't waste time repeating it here:

4.4 Summary

This chapter mainly introduces the three functional areas of the TMM main interface and their respective core functions: movies, movie series and TV shows.The main interface of TMM is the operation center of the entire media library, covering functions such as updating media library, searching & scraping, editing, renaming & organizing, etc., allowing users to complete most management operations in a unified interface and keep the database complete, accurate and visual.

It is important to note that if you decide to use TMM as your primary media resource management tool,All operations are best completed within TMM：For example, adding videos, deleting videos, adjusting folder structures, etc. should all be performed through TMM, rather than directly modifying the file system externally. The reason is that TMM's database is based on its internal index and metadata records. If you delete or move videos directly in the file system,Clicking "Update All Media Catalogs" often doesn't fully recognize these changesIn order for TMM to correctly synchronize external modifications, the media directory must ideally be deleted, re-added, and scanned.

Therefore, if you are more accustomed to managing film and television resources directly in the file system (I am like this, I have always been accustomed to using everything to assist in finding and managing resources), TMM is not suitable as a tool for frequent daily file management: deleting the media directory and then re-adding and rescanning it may take 1-2 hours each time, which is especially time-consuming for large-scale media libraries. For such users,TMM is more suitable as a "professional auxiliary tool for media library initialization and centralized scraping" rather than an everyday add-remove managerFor example, before installing a new Emby server and adding a media library, you can use TMM to scan and scrape all media library directories, generate nfo files, and then add the media library to Emby; subsequent daily scanning and scraping can be done directly by Emby.

When adding, deleting or moving videos daily, it is best to do basic organization when downloading to reduce subsequent maintenance costs.

5. Deduplication and Statistics: Using TMM to Clarify the Number of Movies

5.1 The "disappearing video mystery" caused by the Emby upgrade

For those who have a habit of downloading and collecting film and television resources,Regularly classify and organize resourcesInitially, this organization might have been done simply to keep the collection "tidy" and "easy to find," but as the collection soared to thousands or even tens of thousands of titles, minor issues that could have been ignored would become major problems that had to be addressed.

Taking movie resources as an example, the two most typical problems are:

• More and more duplicate resources

This problem is almost inevitable, as the same movie can have multiple titles, languages, and even remakes from different eras. Before downloading, I usually search for the same movie in Everything to confirm whether it's already available, and check the resolution, compression group, and audio format of the existing version. However, searching by Chinese title is often inaccurate, as the same movie may have multiple translated titles. While searching by English title is better, it's not necessarily safe. For example, some films' English names are inconsistent across IMDb, Douban, or the compression group, and may even contain titles from other languages.

Over time, these subtle naming differences accumulated into a large number of duplicate files - especially since I tend to keep the "best version", whether to delete the old version and which one to keep becomes a difficult decision.

• Inaccurate quantity statistics

In the past, I relied heavily on Emby's media library statistics to calculate the total number of movies. However, since Emby upgraded to version 4.9, some of the underlying mechanisms have changed significantly. For example, a new option has been added to the media library settings: "Multi-version project detection", and it is enabled by default:

The result is that the total number of my movies dropped from 19,108 to about 18,700, which is a decrease of more than 400 movies. Emby believes that these more than 400 movies are "duplicate versions" and merges them into what it considers to be the same entry.

But is this really the case? Because these differences may also come from Emby's identification mechanism, such as differences in nfo metadata, slight differences in file name rules, symbol or path recognition anomalies, etc. In other words, these more than 400 movies may not be true duplicates, but may be "misidentified" by Emby.

To verify this, I need TMM to perform cross validation.

5.2 Off-topic: Why am I concerned about duplicate resources and statistical accuracy?

Maybe some of you don't understand why I care about these little things that most netizens don't care about at all. Let me put it this way, my total number of movies in Emby is 18,725 (9,948+6,395+978+694+710):

The number of viewers reached 19,000 in just the past two months, not including the 447 single-episode documentaries:

243 documentary series:

332 concerts:

759 cartoons:

And 2339 TV series (587+701+558+225+184+84):

To give you an idea, here’s a comparison of the number of movies available on major streaming platforms (as of 2025):

platform	Average number of films worldwide	Number of episodes (seasons/episodes)	Remark
Netflix	≈ 3,500 – 4,500	More than 2,000 TV series	The number varies greatly by region (the United States has the most, while some countries have as few as 2,000)
Amazon Prime Video	≈ 8,000 – 12,000 units	Thousands of TV series	One of the platforms with the most movies, but the quality varies
Disney+	≈ 2,000	Hundreds of TV series	Focus on own content (Marvel, Pixar, Star Wars)
HBO Max (Max)	≈ 3,000	Hundreds of TV series	Focus on classics and self-produced dramas
Apple TV+	< 500	< 200 TV series	Take the boutique route
Hulu	≈ 4,000	About 1,500 TV series	Content partially overlaps with Disney+
Tencent / iQIYI / Youku (China)	Difficult to count, approximately 3,000 – 6,000	Mainly a large number of TV dramas	Emphasis on "series", not movie-oriented

That is, from a film perspective alone, my collection is approximately Four times as much as Netflix,near Amazon Prime Video's global library is one and a half times larger; As for the series, if cartoon content is included, it also exceeds 3000, has surpassed Netflix in all aspects and is second only to leading platforms such as Amazon Prime Video.

In other words, my entire media collection,It has actually reached the scale of the world's mainstream streaming media platformsMore importantly, these films are almost all re-encoded from the original Blu-ray discs, including 2,753 4K films (2,065+631+57):

In terms of quality, it has already exceeded the compression standards of general streaming platforms. Strictly speaking, this can no longer be called a "home video library", but more like a Semi-professional Private Media Archive.

When a collection reaches this size, any minor identification errors, naming differences, or statistical biases will be magnified into systemic problems at the global level.

5.3 Using TMM to Count Duplicate Resources

Although TMM also has a filter with a "show duplicates" option:

But it is not easy to use in practice, because its logic for judging duplication is very simple: it basically only looks atFilm title and year, and does not consider file path, video resolution, size, or even TMDb ID. This results in a large number of "same name different movies" and "remakes" being mistakenly identified as duplicates, while movies that are actually saved duplicated due to inconsistent naming are not detected.

So I finally took a more direct approach: using TMM's "Export Movie List" function to export the entire media library into CSV file, and then filter in Excel or Numbers.

The specific method is very simple:

1. In TMM, select all files in the "Movies" module, and then select "Export Movie List" in the "Edit" drop-down menu:
   
   

2. Select CSV format and export as a "movielist.csv" file:
   

   

3. Open Excel and import the "movielist.csv" exported in the previous step from "Data" - "Import from Text/CSV":
   

   
   
   
   

4. After opening the exported table, selectTitle In this column, use "conditional formatting" to highlight duplicate items in red:
   

   
   
   Finally, click "OK":
   
   

5. Then, manually judge based on year, path, and file size to confirm which resources are truly duplicates:
   
   

While this step is a bit clumsy, it is currently the most accurate and controllable method. Especially for a library like mine with tens of thousands of videos, the cost of automatic detection is too high, and manual review is more reliable.

After removing duplicates, we found at least 312 duplicates across all categories, for a duplication rate of approximately 312/19,108, which equals 1.61 TP4T. This ratio isn't particularly high—after all, with a library of nearly 20,000 movies like mine, duplications are easily present with even the slightest naming discrepancy and a mix of different versions (e.g., original Blu-ray discs, remastered versions, or different soundtracks). The average user's duplication rate is typically between 0.51 and 21 TP4T, which is perfectly normal.

The final TMM statistics are 18738:

This is roughly consistent with the 18,725 reported in Emby (after turning off "multi-version project detection"). The difference is probably due to Differences in counting rules and visibility between the two: For example, TMM may count each actual file as a separate entry (including small variants or residual files with different resolutions/suffixes), while Emby may filter out certain file types during scanning, ignore metadata with irregular naming (such as NFOs such as .mkv.nfo that are not recognized by the new rules), or fail to count some files due to permissions, mount delays, path aliases, hidden folders, etc.

The number statistics after turning off Emby's "Multi-version Project Detection" function are basically consistent with the TMM statistics, which indirectly shows that the "Multi-version Project Detection" function still has defects (I have also tested it, and the total number of Emby statistics will be less than 240 after turning on "Multi-version Project Detection"). The key point is: if you really want to deal with the problem of resource duplication, turning on this option will not solve the duplication problem. It can only be regarded as "out of sight, out of mind", which is a bit like covering one's ears and stealing the bell.

---

There are many other ways to export movie lists, including several HTML options, such as:

For example, after clicking the "007: Golden Eye" link, the effect is as follows:

There are other more impressive display methods, such as those that support search functions. Unfortunately, the HTML files exported by these methods are very large. The smallest one, the one shown above, is nearly 5MB in size, while the other flashier and more feature-rich ones can be over 50MB in size. They are only suitable for local viewing (local opening is extremely slow and has even caused the browser to freeze).

---

6. Postscript: Statistics are just a means, management is the key

After comparing Emby and TinyMediaManager, I have a few thoughts to share with you:

1. Statistical quantity does not equal actual content

While it might seem like "hundreds of movies are missing," many of these issues are simply due to different software recognition logic, or inconsistencies in naming, suffixes, and NFO file formats. To truly understand the full picture of your collection, relying on a single tool or software's default statistics is far from enough.

2. Different tools have different focuses

• The advantages of Emby areDaily viewing and automatic scraping, it can help you organize most of your media library into a state that can be played directly, but its multi-version detection or duplicate judgment logic is not perfect.
• The strength of TinyMediaManager isExport and detailed statistics, which is particularly suitable for large-scale media libraries, scenarios that require precise quantities or manual duplication verification.

Therefore, using a combination of the two is often safer than relying on a single one.

3. The repetition rate is actually not that scary

My statistics for nearly 20,000 movies show a duplication rate of approximately 1.61 TP4T, which is quite low for any large collection. Most duplications stem from differences in Chinese titles, resolution, audio tracks, or minor editing differences. For most users, a duplication rate of 11-21 TP4T is sufficiently tidy.

4. Methodology is more important than tools

My experience this time taught me:Export the list first, then compare it with ID + file path, and finally manually review it, which is much more reliable than relying on software automatic detection. Statistics are just a means,Maintain standardized naming, unified NFO format, and clear folder structure, is the foundation for long-term management of large libraries.

In short, this statistics not only gave me a clearer understanding of my own collection, but also made me understand the limitations and advantages of various tools. For a collector like me who owns more than 10,000 high-quality movies,Clear statistical logic + precise management methodIt is far more important than simply relying on automatic scraping.
