As a user you do of course not have to use any feature related to files; AniDB offers many features that are completely unrelated to them. There is also the concept of ''generic files'': If you want to add an anime to your mylist, but watched it on TV, have it on DVD or just don't care about registering actual files, see [[Files:Generic files]].

==Content==
==Metadata==
 
===Technical information===
Information that is of technical character and in most cases indisputable after verified by [[Avdump]]. For track level information, see [[Content:Files:Video]], [[Content:Files:Audio]] and  [[Content:Files:Subtitle]].
 
====Type====
The type of file. Possible values: ''video file'', ''subtitle file'', ''audio file'', ''other''.
 
====Extension====
Short name of the container format, see [http://en.wikipedia.org/wiki/Filename_extension wikip]. Possible values: ''avi, mkv, ogm, mp4, wmv, str, mpg, ssa, rm, sub, idx, rar, ass, smi, mov, zip, txt, swf, flv and ace''. Deprecated values: ''rmvb, asf, mpeg''.
 
====Size====
The actual size of the file in bytes.
 
====Check/Hash sums====
The [http://en.wikipedia.org/wiki/Hash_function hash sums] are used for verification and identification puposes and includes ''CRC32, ED2K, MD5, SHA1 and TTH''. Size+ED2K is the unique identificator used in AniDB.
 
====Duration====
The playback duration in <tt>hours:minutes:seconds</tt>.


===Release information===

====CRC status====
====CRC status====
Most groups release files with corresponding CRC32 checksums; in the filename, in a sfv file or on their web page. If the calculated CRC32 sum of a file matches the sum provided by the group then the status is set to ''matches the official CRC''. Otherwise, it is set to ''does NOT match the official CRC''.  
Indicates whether the file entry in AniDB represents a perfect copy of the original file or not. Read more about [http://en.wikipedia.org/wiki/File_verification file verification] if you are unfamiliar with this subject.


If no sum is provided by the group or if you can't bother to compare, then set it to ''not compared to the official CRC''. If no CRC sum is registered in AniDB then this field has no meaning and can be ignored.
{{eyecatch|Note|Not all groups provide CRC checksums for their files. This means that this status has no meaning and will have the value "not checked against official crc".}}
 
Allowed sources for official CRC:
* Official sfv (good source)
* CRC listing on official page/IRC topic (good source)
* CRC tag in filename (not a good source, but works... kinda)
* [http://www.envirosphere.com/ Envirosphere] & [http://www.baka-updates.com/ Baka-Updates] (3rd hand info, but kinda works.)

Even if a group releases two files of the same episode it does not mean that the first has to be marked ''v1'' and the second ''v2''. There are other reasons to do something like that other than correcting mistakes like; different source (DTV/DVD), different sub languages, high and low quality versions, etc.

====Source====
====Source====
Here you can set the source of the raw (unsubbed) anime. If you don't know the source, leave it as "unknown". If you find a tag like "(S)VHS" or "DVD" in the filename, choose the according option from the dropdown-menu.
The original source of the video. Possible values are; ''unknown, camcorder, TV, DTV, HDTV, VHS, VCD, SVCD, LD, DVD, HKDVD, HD-DVD, Blu-ray, www.''
Sometimes, it's ok to make an educated guess: For animes that are released fansubbed shortly (within days/weeks) after they aired in Japan, you can safely assume "DTV" (Digital TV) as source. Another case for educated guessing is "HKDVD" (Hongkong-DVD) - the video-quality may be ok for them, but the translation is usually horrible, which is how you can spot them.
 
When creqing this field you should provide some sort of proof unless the old value is obviously wrong or set to "unknown". This means that you should be sure about the change and not just base it on assumptions. For example, don't creq DTV -> HDTV based on resolution/quality/filesize/etc. only.


====Quality====
====Quality====
Eyecancer, very low, low, med, high, very high.
This is a very arbitrary field. It depends completely on the eye of the beholder. You should not put too much meaning into it, but rather use it as a general pointer of quality. Possible values are; ''eyecancer, very low, low, med, high, very high.''


*This is a very arbitrary field. It depends completely on the eye of the beholder. You should not put too much meaning into it, but rather use it as a general pointer of quality.
Also see: [[Votes: Anime: Group]]
*This field should '''not''' be used to rate releases from different groups. Use anime-group comments/votes to express opinions about such.
*This field should be considered '''per''' group: When multiple releases exists from a group it can (and should) be used to differentiate them.
*Although there have never been any written rules; ''quality is usually bound to source''. Ie. DVD -> very high, DTV -> high, VHS -> low, etc.. It is generally ok to follow this scheme, but don't go about creqing just because of it. There are many good reasons for not following it.
*Note that 'very high' quality rating is not reserved for the theoretical perfect release, or bound to DVD source or anything like that. It can be used more freely to differentiate.
*If you want to request a change, check the history of the file first. It might have some useful information (discussion) about why the current rating was selected and save you from a humiliating deny.
*Feel free to discuss this system in our forum/channel, but '''never''' start a personal creqing spree to "reform" it.

====Private files====
====Private files====
The general rule is that [[Animeentries:Fileentries|file entries]] in AniDB are supposed to be useful for a larger group of users. Adding private files is therefore '''not allowed'''.
====Corruption====
====Corruption====
[[Animeentries:Fileentries|Fileentries]] on AniDB are supposed to be useful for a larger group of users: One of them adds the entry and many others can use it (by adding it to their list).
'''Adding wide-spread corrupted files'''
An entry for a corrupted file may still be useful for others as long as it's likely that more people have the exact same corrupted file as you have. (For example if one source sent the corrupted version to many people.)
An entry for a corrupted file may still be useful for others as long as it's likely that more people have the exact same corrupted file as you have. (For example if one source sent the corrupted version to many people.)


If - and only if - this is the case, you can add the file normally to AniDB, marking it as "CRC invalid" and/or "Quality: Corrupted" if there are visible/audible errors in the file.
If - and only if - this is the case, you can add the file normally to AniDB, selecting ''CRC does not mathc official source'' and/or ''Quality: Corrupted'' if there are visible/audible errors in the file.
 
'''Adding "personal" corrupted files'''


If your specific (corrupted) version of the file isn't listed on AniDB, for example because of some hard- or software-problem on your side or because you manually edited the files, you should '''not add''' them to AniDB as they serve no purpose for other users.
{{eyecatch|Warning|If the corruption is based on some hard- or software-problem on your side, or if you manually edited the file, you should '''not add''' them to AniDB as they serve no purpose for other users.}}


Don't worry - you can still list such files properly in your mylist. For example: You have a corrupted version of group X's release. Navigate to the corresponding episode where the regular, uncorrupted version of group X's release is listed and click on the "add file ()" icon. On the next page, you can select the "Type: corrupted version/invalid crc" so that your mylist-entries properly indicate which version you have.

===How to add===
===How to add===
When you add a new file from a group that already have some files added for this anime, you can save yourself from going through the extra step of searching for the group again and again by using the '''by relation''' list, that contains only groups that already have at least one file added for this anime.<br>
{{missing}}
Otherwise, you have to search for the group. If the group isn't listed, you have to [[Content:Groups|add it first]].
 
'''Note:''' If the file is a ''no group'' file, '''do not set crc correct status!''' Most raw files come from [http://en.wikipedia.org/wiki/Share share] or [http://en.wikipedia.org/wiki/Winny winny] hence no official crc is known!

==File relations==

==Stuff==
See [[Content:File relations]].
Now, there are a few different kinds of files that can be added to the different episodes for anime, but all files have a few fields that apply to them:
 
<div style="border: 1px dotted gray; text-align: center; background-color: #e2e2ff">
[[Content:Files#ED2K_Sum|ED2K Sum]] | [[Content:Files#Various_other_hashes|Various other hashes]] | [[Content:Files#CRC_status|CRC status]] | [[Content:Files#Size|Size]] | [[Content:Files#Type|Type]] | [[Content:Files#Extension|Extension]] | [[Content:Files#Version|Version]] | [[Content:Files#Release_date|Release date]] | [[Content:Files#Released_by|Released by]] | [[Content:Files#Comments|Comments]]
</div>
 
All files, except generics, can also have '''relations''' to other files and/or episodes:
 
<div style="border: 1px dotted gray; text-align: center; background-color: #e2e2ff">
[[Content:File_relations|File relations:]]
[[Content:File_relations#File.3C-.3EFile_Relations|File<->File]] | [[Content:File_relations#How_to_create_a_File.3C-.3EEp_relation|File<->Ep]]
</div>
 
And we also have specific fields that only apply to video files, audio files and subtitle files:
<div style="border: 1px dotted gray; text-align: center; background-color: #e2e2ff">
[[Content:Files:Video|Video files]]: [[Content:Files:Video#Length|Length]] | [[Content:Files:Video#Censored|Censored]] | [[Content:Files:Video#Quality|Quality]] | [[Content:Files:Video#Source|Source]] | [[Content:Files:Video#Resolution|Resolution]] | [[Content:Files:Video#Aspect_Ratio|Aspect Ratio]] | [[Content:Files:Video#Video_Codec|Video Codec]] | [[Content:Files:Video#Video_Bitrate|Video Bitrate]] | [[Content:Files:Video#FPS|FPS]] | [[Content:Files:Video#Video_Flags|Video Flags]]
</div><p>
<div style="border: 1px dotted gray; text-align: center; background-color: #e2e2ff">
[[Content:Files:Audio|Audio files]]: [[Content:Files:Audio#Track_type|Track type]] | [[Content:Files:Audio#Audio_Language|Audio Language]] | [[Content:Files:Audio#Audio_Codec|Audio Codec]] | [[Content:Files:Audio#Audio_Bitrate|Audio Bitrate]] | [[Content:Files:Audio#Channels|Channels]]
</div></p><p>
<div style="border: 1px dotted gray; text-align: center; background-color: #e2e2ff">
[[Content:Files:Subtitle|Subtitle files]]: [[Content:Files#:SubtitleSubtitle_type|Subtitle type]] | [[Content:Files:Subtitle#Subtitle_Language|Subtitle Language]] | [[Content:Files:Subtitle#Subtitle_Flags|Subtitle Flags]]
</div></p>
'''Note:''' for alot of these fields you can use [[avdump]] to analyze the video file. It can tell you most of the things you need to know.
 
And the last two sections in this article are about if something is/has gone wrong:
<div style="border: 1px dotted gray; text-align: center; background-color: #e2e2ff">
[[Content:Files#Your_version_is_corrupted...|Your version is corrupted...]] | [[Content:Files#Removing_bad_entries|Removing bad entries]]
</div>


===Types===
====Video file====
A file with at least video, but normally with audio and subtitles too. This is what you want 99% of the time and hence the default.
====Subtitle file====
A file containing only subs; srt, ssa, sub, idx, ass, smi, txt. Usually having a [[Content:File_relations|relation]] to one or more video files.
====Audio file====
A file containing only audio. Hardly used at all; you will probably never need this.
====Other====
An archive file containing one or more of the other types over; for example subtitles (although such files may be registered as ''Subtitle file'' too), sets of files or part of files. Hardly used, but slightly more common than ''Audio file''.
