Trivial fields

These fields can be supplied manually when adding, but not creqed. They should be automatically set by Avdump3 and are not possible to change after verification.

Length

How many hours, minutes and seconds the file lasts. Just check in your favourite media player. If you have a file that won't display its length correctly, try to use Avdump3 to determine the length.

Resolution

The actual pixel resolution of the video. Width x Height. It should not be confused with display (playback) resolution.

Aspect Ratio

The playback aspect ratio of the video.

Video Codec

A video codec is software that enables video compression and/or decompression for digital video, e.g. h264, DivX, Xvid, wmv9 and others.

Video Bitrate

The average amount of bits per second the codec uses.

FPS

Frames per second. This should be set to 0 if the video is VFR.

Video Flags

Anamorphic: For an explanation of this, see the anamorphic format on Wikipedia.
Clean video: Set this flag if there is nothing hard-subbed by the fansub/DVD-rip group in this file. RAWs are always clean. This flag does not apply to official text, credit-less OP or ED is no different from an OP or ED with official credits.
VFR: Variable Frame Rate.
Wrong Aspect Ratio: If the file was encoded with the wrong viewing aspect ratio, check this box. One way to tell whether this is true is if what should be a circle on the screen isn't completely round, but rather elliptic. Most common example is the native NTSC DVD pixel resolution of 720x480 with no resizing for display (aka not anamorphic), only way this resolution would not be wrong is if there are huge black bars added so the actual content of the anime would be in correct AR.

-==Censored==
+===Resolution===
-This only applies to animes that have both an uncensored and a censored version. If it only has one, leave this setting as the default: Unknown.
+The actual pixel resolution of the video. <tt>Width x Height</tt>. It should not be confused with display (playback) resolution.
-==Quality==
+===Aspect Ratio===
-*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.
+The playback aspect ratio of the video.
-*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 for a humiliating deny.
-*Feel free to discuss this system in our forum/channel, but '''never''' start a personal creqing spree to "reform" it.
-==Source==
+===Video Codec===
-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.
-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.

-==Resolution==
+The average amount of bits per second the codec uses.
-In this field you set which resolution the file has in pixels. Width x Height.
-Or just use [[avdump]].
-==Aspect Ratio==
-Set the playback aspect ratio for the file.

 ===FPS===
-----
+Frames per second. This should be set to 0 if the video is VFR.
-To find out what video codec, bitrate and fps is used for the file, we recommend that you use [[avdump]].
+===Video Flags===
+*Anamorphic: For an explanation of this, see the [[Wikipedia:Anamorphic|anamorphic format]] on Wikipedia.
+*Clean video: Set this flag if there is '''nothing''' hard-subbed by the fansub/DVD-rip group in this file. RAWs are always clean. This flag does not apply to official text, credit-less OP or ED is no different from an OP or ED with official credits.
+*VFR: Variable Frame Rate.
+*Wrong Aspect Ratio: If the file was encoded with the wrong viewing aspect ratio, check this box. One way to tell whether this is true is if what should be a circle on the screen isn't completely round, but rather elliptic. Most common example is the native NTSC DVD pixel resolution of 720x480 with no resizing for display (aka not anamorphic), only way this resolution would not be wrong is if there are huge black bars added so the actual content of the anime would be in correct AR.
