以下是本人读过“标准”后结合目前实际情况的一些主观感受,希望大家积极能参与讨论
绝大多数影片可以在2CD内搞定，除非像“辛格勒名单”，“泰坦尼克”“拯救大兵”片长高达一百九十多分钟的影片。
能在1CD内解决的，绝不拖到2CD
音频部分能使用原声的，尽量不编码成其他格式
多音轨其实是个花架子，保持原声音轨就足够了
avi格式虽然比较老了，但兼容性没得说的，无论是dvd播放机器，还是在pc上。
减小画面尺寸有助于减小容量吗？不知道。但是别人的经验总是有一定道理的，按照画面尺寸直接进行编码是不负责任的行为，不裁剪黑边更是不符责任，其实我们可以做得更好。
追求画质不能成为将影片编码为多CD的借口，除非影片长度确实接近临界区
264编码器的压缩比本来就比xvid出色，所以就更没有理由“为赋新词强说愁”了

These rules take effect March 5, 2009 (2009-03-05) at 00:00 UTC. Thanks to all groups who participated.
以下规则于协调世界时间(UTC) 2009年3月5日零时开始生效，感谢所有参与（遵循此规范）的（发布）小组。
[ RELEASE RULES ]
[ 发布规则 ]
Movie Length:
影片长度：
- Allowed sizes are 175MB, 350MB and multiples of 1 CD (700MB).
- 175MB（1/4CD）,350MB(1/2CD)和多份1CD(700MB)（大小的作品）被允许发布
- The following formula will guide you to get the appropriate size:
- 下列公式将正确地指导你得到适合的容量：
target-size = VIDEO-FPS * VIDEO-RUNTIME(in mins) * 0.28
目标容量 ＝ 视频fps × 视频（正片？）长度（以分钟为单位） × 0.28
Use the target-size value to index the MAXIMUM allowed size, examples:
使用目标容量值作为最大允许容量的参考，例如：
target-size = 25.000fps * 98min * 0.28 = 686, MAX size is 1 CD
目标容量 ＝ 25.000fps * 98min * 0.28 = 686，最大容量为1 CD
target-size = 23.976fps * 49min * 0.28 = 329, MAX size is 1/2 CD
target-size = 18.000fps * 65min * 0.28 = 328, MAX size is 1/2 CD
VIDEO-RUNTIME is in minutes only, no fractions, and rounded up to the next full minute, e.g. 104 min and 5 secs = put 105 min inside the formula. The following table describes the MAXIMUM size allowed for each runtime in minutes:
视频（正片？）长度只能使用分钟（来计算），没有零头，（如果有零头）并且计入下一分钟，
例如：104分钟零5秒 ＝ 105分钟，将105分钟代入公式
FPS|175MB |350MB|700MB |1400MB | 2100MB
23.976 | -26|26:01-52 |52:01-104 |104:01-208 |208:01-312
以23帧每秒的影片为例，正片长度在26分钟以下的标准容量为175MB（1/4 CD）
正片长度在26分钟以上52分钟以下的的标准容量为350MB（1/2 CD）
正片长度在52分钟以上104分钟以下的的标准容量为700MB （1 CD）
正片长度在104分钟以上208分钟以下的的标准容量为1400MB （2 CD）
正片长度在208分钟以上312分钟以下的的标准容量为2100MB （3 CD）
25.000 | -25|25:01-50 |50:01-100 |100:01-200 |200:01-300
29.970 | -20|20:01-41 |41:01-83| 83:01-166 |166:01-250
- The above table indicates the MAXIMUM size allowed to encode at, but it is ripper's discretion to use smaller values, e.g. 110 min PAL movie can use AT MOST 1400MB but can also use lower sizes such as 700MB.
- If at the lowest resolution allowed and MP3 audio bitrate of 128 kbps average I/P quant is above 4.5, releases may jump 1 size up (e.g. 2 CDs may be used instead of 1). Such cases MUST provide proper proof and explanation in the nfo.
TV Length:
- All Episodes <RETAIL rips> are obligated to follow these rules.
- Allowed sizes in MB are 175, 233, 350 and multiples of 700 (an extra OPTIONAL size is 550MB, see below).
- Use the same target-size formula listed above to determine appropriate sizing. Some examples are:
target-size = 25.000fps * 20min * 0.28 = 140, MAX size is 175 MB
target-size = 23.976fps * 60min * 0.28 = 403, MAX size is 700 MB
target-size = 29.970fps * 25min * 0.28 = 210, MAX size is 233 MB
*VIDEO-RUNTIME is in minutes only, no fractions, and rounded up to the next full minute, e.g. 41 min and 5 secs = put 42 min inside the formula.
- 550MB may be used at ripper's discretion when target-size is above 260MB.
- If the formula gives a value below 100MB, sizes smaller than 175MB are allowed, at ripper's discretion. It is also ripper's discretion to use smaller sizes than those targeted by the formula for each specific runtime and framerate (e.g. a release that should be 350MB according to the formula may also be released at 233MB).
AUDIO:
音频部分：
- MUST be VBR MP3 or Studio AC3.
必须为VBR编码的mp3或者AC3格式
- ABR is considered a VBR technique.
ABR编码也被认为是一种VBR编码技术。
- MUST be STEREO for STEREO sources, MONO for MONO sources
立体声来源必须编码为立体声，单声道来源（必须编码）为单声道
(Any audio track with identical channels is considered a MONO source).- MP3 tracks must keep the original frequency as it was on the source's audio: e.g. 48khz for 48khz and 44.1khz for 44.1khz.
- 当MP3作为音轨时必须保持原始采样频率
- Mono or Dual Mono (1+1) AC3 is forbidden; use mono MP3.
- MP3 audio must be normalized. Stereo sources must use stereo or
joint-stereo encoding mode. Mono sources must use mono encoding mode;
dual-mono is forbidden.
- Encoding or re-encoding audio to AC3 is strictly forbidden, except in
in the case of HD retail source (see Source related notes).
- Use of AC3 is at the ripper's discretion, but should be used wisely.
Choice of AC3 or MP3 is not a technical flaw except as otherwise noted.
- Multi-language audio tracks are FORBIDDEN! (Use INTERNAL)
VIDEO:
视频（部分）：
- Keyframe:
- 关键帧
MUST be <=20 seconds and MUST be inserted according to scene changes and framesizes as determined by the codec or encoding application.
必须小于二十秒，必须被插入到场景变换和编码应用程序和编解码器侦测到的帧大小
- Group watermarks of any kind on the video are forbidden.
- 禁止在视频中出现发布团体的水印（标记）。
- English retail releases may not contain foreign language text overlays from localized versions.
Framerate:
帧率：
- MUST be as close to original source framerate as possible.
- 必须尽可能地接近原始帧率。
- In some cases PAL movies need to be IVTC'd (e.g. to 24fps). Therefore using a PAL source is not an excuse for lack of IVTC.
- Hybrid sources are left at ripper's discretion if to IVTC or not. Ripper should mention and provide proof to any claim for ITVC or lack thereof.
Codec:
编解码器：
- MUST BE XviD (all DivX codecs are banned).
- 必须是XVID编解码器（所有divx的编解码器都被禁止）。
- MUST use 2 pass technique during encoding.
- 在编码期间必须使用二次编码技术。
- No dupes based on codec type, use INTERNAL!
Resolution and Aspect Ratio:
分辨率与宽高比
- Width: 576 - 640 pixels for movies with an AR of 1.70-3.00*
512 - 640 pixels for movies with an AR of 1.00-1.69
- Width and Height must be multiples of 16.
- 图像的宽与高必须为16的整数倍
- Cropping is required such that black borders are cropped to their maximum. In the case that the video presents changing ARs, the video must be cropped such that no frame is overcropped.
* Over- or undercropping by more than 1 pixel is considered a technical flaw（缺陷）, although it is preferable to crop the 1 pixel out.
- Video encodes must be within 4% of the original aspect ratio. Calculating AR % error: (Original AR - Release AR)/Original AR x 100
- Non-retail video sources may not have the usual retail aspect ratio due to different processing. All releases should be based on the actual
source AR, not on retail AR listed on IMDB or other sources.
Subtitles:
- OPTIONAL (ONLY if all other requirements have been met).
- Subtitles MUST be packed in a RAR file with the most compression
available. This RAR file shall be placed in a directory named 'Subs'
along with an SFV file containing standard checksum information for
that RAR. The subtitles must not be packaged in the main RARs for the
release and the RAR file containing the subtitles must not be listed in
main SFV for the release.
- Vobsub packs must have the .sub file packed with the MOST compression:
subs.rar = [ <avi-name>.idx + <avi-name>.rar = (<avi-name>.sub) ]
- Burned subtitles are only permissible when present in the source. If
the subtitles overlay both active video and matting (black bars),
cropping to the bottom of the subtitles is permissible, and an equal
amount of matting shall be left at the top. If the burned subtitles
overlay only matting, they must be OCR'ed and cropped out.
- English subs on non-English releases MUST fit in the standard size
with the rest of the release. All other subs are considered optional
and are not required to fit in the standard release size.
- English subs on non-English releases must be synced with the video.
- Foreign releases (non-English spoken) lacking English subtitles MUST be
tagged with the spoken language. Releases with English subtitles MUST
NOT be tagged with the spoken language. A release containing English
subtitles after a foreign-tagged release is not considered a dupe,
regardless of whether or not the foreign-tagged release has English
subs.
- Subtitles on multiple-CD releases must be split. Inclusion of non-split
subtitles in addition to the split subtitles is encouraged.
- Custom subtitles are not allowed on retail sources. They may be used
only with non-retail sources. Propers for incorrect or missing dialogue
on custom subtitles are not allowed; release a subpack!
- Multi-language subtitles cannot be used as a basis for a dupe.
- English subbed (with original spoken language) may follow a dubbed
release (in any language); use SUBBED tag.
Packaging:
封装：
- All releases MUST be AVI.
- 所有的发布必须为avi格式
- Must be packed with RAR and broken into 15 or 20 MB volumes.
Each AVI for a multiple-CD release must be packaged into separate RAR
volumes.
- Filenames (even subpack rar file) MUST be unique (to avoid dupe).
- 文件名必须唯一（避免重复）
- Compression is not allowed.
- 不允许压缩
- Recovery and MD5 record are recommended.
- Must have an SFV included for each CD.
- Must have an NFO.
- 必须带有一个nfo文件
- NFO SHOULD INCLUDE:
- NFO文件应该包括：
Group name
Title
Actual XviD release date
DVD release date
Theatrical release date (US preferably)
Video size
Resolution / Aspect Ratio
Audio codec / Audio bitrate
Video bitrate
Movie runtime
IMDB / Amazon / Any other DVD site info link
Number of rars per CD (e.g. 50x15MB)
XviD build
Packed Bitstream
Maximum consecutive B-frames
Credits:
- Credits may be encoded at a lower bitrate unless they contain sceneslike bloopers or continuation of story.
- Cutting credits on RETAIL sources is not allowed.
Samples:
- Sample is required and must have a unique name for each release.
- 1 full minute in length and in a separate folder marked as 'Sample'.
- MUST be taken from the video, NOT encoded separately.
- Source samples are recommended for any rip that is deemed questionable: no IVTC possible on source, IVTC to 24.975fps, etc.
Propers:
- Propers are only permitted in the case of a technical flaw in the original release (e.g. bad.ivtc, interlacing, oversized).
- Propers MUST include a note in the NFO file detailing the reason.
- Releases not nuked on release lists and/or sites MUST include original sample of the technical flaw in the release sample dir.
- Qualitative propers are not allowed, nor are propers based on decisions made by a ripper (e.g. AC3 or MP3).
- Propering a release done under a previous ruleset timeline is allowed
if it has a technical flaw, such as bad.ar, bad.ivtc, over.cropping.
Other propers acceptable are propers based on releases that did not
follow previous guidelines at the time they were pred.
- Releases containing hardcoded subs may be propered by non-hardsubbed
video. Original release SHALL NOT be nuked.
- Propering a release when a working fix is released is not allowed.
- Sizefixes are not allowed.
- Propers based upon the compliance with new instances of TXD2K9 are
allowed only for releases after 2009-03-05.
WS vs. FS:
宽屏与全屏：
- WS or FS name tags on the release name are allowed.
- A WS release after an FS release (and vice versa) requires proof that the new release contains more picture area than the original release (provide sample from the original release or JPG screenshot of the same frame in both releases showing additional area). A release not documenting additional picture area is considered a DUPE.
- Wider wide screen where more of the original source is visible is valid
& not considered a dupe but should be tagged as WS not PROPER. Original
release should not be nuked. Provide proof as listed above.
- Letterboxed DVDs are not considered FS even if the aspect ratio flagged
on the disc is 4:3; only active picture area should be considered.
Special Movie Editions:
特殊版本的影片：
- Allowed: DC, EXTENDED, UNCUT, REMASTERED, UNRATED, THEATRICAL, CHRONO,
SE (or any other special edition, e.g. AE).
- Special Edition releases with same time length as previous released versions of the movie shall be considered dupes.
- Shorter cut version of a movie after a longer version was released is allowed (e.g. THEATRICAL), and MUST be mentioned in the dirname.
- Remastered movies after the original have been released are allowed only if one of the releases is BLACK AND WHITE and the other is colour. Everything else use INTERNAL! (Remastered DVD releases that were nuked in the past and were colour after black&white and vice versa, shall not be unnuked and shall not be duped!)
- Extras released in a special movie edition can not be used as a basis for a dupe, unless released separately (and are not dupes of previous releases).
- Homemade rips are not allowed (Use INTERNAL!).
- NOTE: PAL - NTSC length difference comes from the no. of frames per second and not extra footage.
Directory and File Naming:
目录及文件命名：
- All releases need to include production year.
- 所有的发布需要包含出品（影片和电视节目的）年份
- DO NOT indicate ripping method, DVD/XviD release date, genre, audio
which was used (no AC3) or anything else! (ONLY WITHIN THE NFO)
- Movie distribution tags e.g. FESTIVAL, STV, LIMITED or TV (TV tag
is used for TV movies only) are allowed and shall be used wisely and
correctly.
- READ.NFO tag is allowed, but shall not be abused.
- Other permitted tags are: WS/FS (rules above), PROPER, REPACK, RERIP,
REAL, RETAIL, EXTENDED, REMASTERED, RATED, UNRATED, CHRONO, THEATRICAL,
DC, SE, UNCUT, INTERNAL, DUBBED, SUBBED, FINAL, COLORIZED.
* Use RERIP for ripping issues and REPACK for packing issues.
* RERIPs/REPACKs must use different file names from previous release.
- Acceptable characters in naming a directory include (NO spaces or
double dots - single dots or underscores ONLY):
ABCDEFGHIJKLMNOPQRSTUVWXYZ
abcdefghijklmnopqrstuvwxyz
0123456789.-_
- Releases that are more than 1 CD MUST be named CD1, CD2, CD3 and so
on ('disc1' and others are NOT allowed).
- 多于1 CD容量的发布必须被命名为CD1, CD2, CD3等等（'disc1'与其他方式的命名不被允许）
Source related notes:
来源发布注意事项：
- HD retail may be used as source only if no DVDRip has already been
released (and vice versa). Such releases must be tagged accordingly
(e.g. BDRip, HDDVDRip).
- When using AC3 on a rip from HD retail source, re-encoding DTS, LPCM,
TrueHD, DTS-HD and 640kbit/s AC3 to 448kbit/s AC3 is mandatory.
- Re-encoding material of any transcoded source is strictly forbidden!
- HD retail rip released after 1080p/720p needs source proof (a raw m2ts
sample including all audio/subtitles tracks) in sample dir.
- R5 is not considered retail.
- Non-studio audio must be tagged accordingly, e.g. LINE audio.
* Releases provided with studio audio do not dupe releases with non-
studio audio. The reverse does not apply!
- The use of sources like CAM, TS, TC, Workprint, SCREENER, Laserdisc
etc. MUST be tagged with source in the dirname and must adhere to ALL
TXD2K9 rules!
- DVD Screeners shall be clearly marked in the directory name and the
nfo shall contain presence of studio watermarking, black&white scenes
and counters or lack thereof.
Internals:
- INTERNALS should follow all TXD2K9 rules and are exempt from the time
length rules.
- Multi-language audio tracks are allowed. Multiple languages should be
interleaved into the AVI, with a graphedit filter for each appropriate
audio stream.
- Other codecs and containers are allowed for experimental purposes.
- INTERNAL dirfix should not be used as a basis of avoiding a nuke.
Ripping related notes:
- MAXIMUM bitrate must not exceed（不超过）4854 for more than a second and must not exceed 8000 kbps ever. DivX Home Theatre and MTK (not 6000) profiles follow these guidelines.
- Quantizer matrix MUST be H.263 or MPEG. Custom matrices are forbidden
due to lack of standalone support.
量化矩阵必须是H.263或MPEG.
- Pixel shape MUST be square.
- Quarter_pixel/GMC are forbidden due to lack of hardware support.
由于缺乏硬件支持Quarter_pixel /GMC（Globe_Motion_Compensation）被禁止使用
- The use of ITU-R (Gknot function) is not recommended.
- 不推荐使用ITU-R（GKnot功能）。
