- Lªªª[ INTRO ]ªªª- -
- -
- x264 has become the most advanced video codec over the past few years. -
- Compared to XviD, it is able to provide higher quality and compression at -
- greater SD resolutions. It also allows better control and transparency over -
- encoding settings. With CRF in the mix, we can also ensure that a diverse -
- array of material will get the most appropriate bitrate for them and not -
- arbitrary and fixed sizes. This standard aims to bring quality control back -
- to SD releases. There are many standalone players/streamers such as TviX, -
- Popcorn Hour, WDTV HD Media Player, Boxee, Xtreamer, PS3, XBOX 360, iPad, & -
- HDTVs that can playback H264 and AAC encapsulated in MP4. -
- -
- The SD x264 TV section was formed to separate releases from the ruleless -
- world of TV-XviD. This document will cover the rules and guidelines for -
- only SD resolution x264 television rips. -

- Lªªª[ RELEASE RULES ]ªªª- -
- -
- Compliance with this document is optional as of its pre date, and -
- mandatory as of 2012-02-22 16:00 UTC. -
- -
- Video: -
- - Sources requiring resize are to be cropped and resized using sharp -
- resizers such as Lanczos/Lanczos4, Spline36, or Blackman. Bicubic is -
- banned. -
- - HD video taken from the decoded HD output of a set-top box (e.g. -
- component, DVI, HDMI) may be used as a source; source must be tagged -
- in dirname as AHDTV. Decoded output of PDTV or DSR sources is banned. -
- Releases taken from a natively recorded transport stream shall be tagged-
- as HDTV, PDTV, or DSR. Dupes are as follows: HDTV > AHDTV > PDTV > DSR. -
- AHDTV captures must be done at the native format of the channel, e.g. -
- 720p or 1080i. -
- - Sources that sideconvert 1080i to 720p (such as BellTV) are allowed but -
- must be tagged as PDTV or DSR. -
- - If there is a question as to the validity of a source, the release -
- may be nuked source.sample.requested_<reason.for.nuke> (e.g. -
- source.sample.requested_suspicion.of.analog.source) within 24 hours of -
- pre. The group has 24 hours from the nuke to pre a RARed SOURCE.SAMPLE -
- that is at least 10 seconds in length in order to document that the -
- source is valid. Failure to provide source proof or providing bad -
- source proof shall result in the release remaining nuked, and it may -
- then be propered. -
- - Improper IVTC methods that result in jerky playback, such as Force -
- Film, are banned -
- - Interlaced video sources must be deinterlaced with a smart deinterlacer -
- such as Yadif. FieldDeinterlace is banned. -
- - Group watermarks of any kind on the video are banned -
- - Intros, outros, betweenos, or any other form of defacement of the -
- episode are banned -
- - "Native" refers to the standard in which the video was produced (e.g. -
- NTSC or PAL). NTSC produced video is native to NTSC, PAL produced video -
- is native to PAL. PAL produced video that is broadcast in NTSC is -
- converted. NTSC produced video that is broadcast in PAL is converted. -
- - Converted video that has significant artifacting (e.g. blended frames) -
- and cannot be reversed to native must use CONVERT tag -
- - Converted video that does not have significant artifacts does not need -
- convert tags and may not be nuked for the conversion -
- - Native releases are allowed after those tagged CONVERT. Use NATIVE tag. -
- -
- Audio: -
- - Allowed audio formats are VBR AAC LC (Low Complexity). -
- - Average bitrate on AAC audio must be 96 - 160 kbps. -
- - AAC audio must be normalized and downconverted to stereo. -
- - Nero and Apple encoders are recommended. FFmpeg is banned. -
- - Dupes based on audio format are forbidden and must be tagged INTERNAL -
- - Multiple language audio tracks are allowed and must be listed in NFO -
- - Dupes are not allowed based on multiple audio tracks -
- - Severe audio drops resulting in one full missing word or otherwise the -
- inability to understand material dialogue is considered to be a -
- technical flaw and may be propered -
- - Audio that is 120ms or more out of sync or drifts more than 120ms -
- between any two points (e.g. needing -80 at one and +40 at another) is -
- considered to be technically flawed and may be propered -
- -
- Framerate: -
- - IVTC or deinterlacing must be applied as needed -
- - 50/60fps video may be released at 50/60fps or 25/30fps. Releasing true -
- 25/30fps video at 50/60 is considered a technical flaw. -
- - In rare cases, 25/50Hz sources should be IVTC'd to 24 or 30 fps. -
- - In rare cases, 30/60Hz sources should be IVTC'd to 25fps. -
- Failure to apply IVTC when needed is a technical flaw. -
- -
- Codec/Container: -
- - Video codec must be x264 (8-bit depth). -
- - Container must be MP4. -
- - You will have 30 days from latest x264 rev date to update in order to -
- maintain all bug fixes and improvements in the x264 codec -
- - Stripping or falsifying encode information in the file header is banned -
- - Custom muxing tools are permitted; however, output must be compatible -
- with standard demuxers. -
- - Custom Matrices are allowed -
- - Encoded colorspace must be 4:2:0. -
- - Deblocking must be used; values are at the discretion of the group. -
- (default is enabled, 0:0 settings) -
- - No setting can go below what is specified by --preset slow. -
- - Keyframe interval (--keyint) must be at least 200 and at most 300. It -
- is recommended to be 10*framerate (film=240, PAL=250, NTSC=300). -
- - Minkeyint must be 30 or less -
- - Colormatrix must be set to source specification. If not specified by -
- source, bt709 must be used for sources with resolution greater than or -
- equal to 1280x720 (e.g. HDTV and some PDTV) and sources with lower -
- resolutions must use bt601 (e.g. DSR and some PDTV). -
- - Constant Rate Factor (--crf) must be as follows: -

- - x264 parameters shall not vary within a release -
- - Zones (--zones) are forbidden. -
- - Any deviation in CRF from given examples must be specifically justified -
- in the NFO. Use discretion when deviating CRF by matching the -
- compressibility of the show to a corresponding CRF value. CRF values -
- below 19 and above 24 are never permitted. -
- - As a general suggestion, average video bitrate in excess of 1500kb/s -
- is a sign that a higher CRF value should be chosen, when possible -
- - Allowed parameters for --tune (optional) are film/grain/animation -
- - Level 3.1 must be respected. -
- - Suggested command line: -
- x264.exe --crf ## --preset slow --level 3.1 --colormatrix bt709 -o -
- out.h264 in.avs -
- -
- Resolution: -
- - WS HDTV and WS PDTV sources with greater than 720px horizontal res must -
- be cropped as needed and resized to 720px width and mod2 height to -
- maintain proper AR. -
- - WS PDTV sources with horizontal source res of 720-704px must be cropped -
- as needed and only height must be resized to the proper anamorphic AR -
- using mod2. Upscaling/downscaling is forbidden. -
- - All other sources, including FS HDTV, must be cropped as needed and -
- resized to 640px width and mod2 height to maintain proper AR. -
- - When cropping, remove everything that is not actual picture, including -
- black or other colored borders, duplicate lines, and full-time tickers. -
- Removing or retaining fading edges is at capper's discretion and shall -
- not be considered undercropped or overcropped. -
- - In the case of varying crops, crop to the most common frame size (e.g. -
- pitch/primary view in sports). -
- - Actual picture area may be over- or under-cropped by 1px maximum per -
- side. More than 1px on any side is considered a technical flaw. -
- - Encoded Video resolution must be within 2% of the original aspect ratio -
- To calculate AR error (%): (Original AR - Release AR)/Original AR * 100 -
- OAR = (SourceWidth-CropLeft-CropRight)/(SourceHeight-CropTop-CropBottom)-
- Release AR = EncodedWidth / EncodedHeight -
- -
- Subs: -
- - Optional, but encouraged -
- - Text based format is preferred (e.g. SubRip, SubStation Alpha, etc). -
- - Subtitles must be in "Subs" directory. -
- - Burned subtitles will only be allowed when the source exhibits such -
- subtitles in the picture itself -
- - Subtitles cannot be used as a basis for a dupe -
- - Group marks in subtitles are banned -
- -
- Packaging: -
- - Releases must be packed in RAR file format. -
- - Rars may be in 15, 20, or multiples of 50 MB. 15 and 20 MB sizes must -
- contain 1-101 files. Multiples of 50 MB must contain 10-101 files. -
- 1MB = 1,000,000 bytes. -
- - Multi-episode releases with no clear delineation such as credits must -
- not be split -

- - Recovery and MD5 record are optional -
- - Encryption or password protection is forbidden -
- - Must have SFV and NFO -
- - RAR, SFV, and sample files must have unique, lowercase filenames with -
- the group tag. -
- - Missing SFV or RAR(s) on all sites is considered a technical flaw. -
- Corrupt RARs (errors on extraction) are considered technical flaws. -
- SFVFix and RARFix are not permitted. Uploading a missing SFV or RAR to -
- all presites after pre is not permitted. Release REPACK. -
- -
- Credits/Previously On: -
- - Previously on footage is optional, but suggested to be included -
- - Full end credits must be included if they contain show content or -
- outtakes/bloopers. End credits are optional and suggested if they are -
- clean, and purely optional in other cases. -
- -
- Samples: -
- - REQUIRED! -
- - 50-70 seconds in length and in a separate folder marked as Sample -
- - Must be taken from the episode, not encoded separately -
- - Stream samples are recommended for any questionable issue with the -
- source, e.g. no IVTC possible -
- -
- Propers: -
- - Propers are only permitted in the case of a technical flaw in the -
- original release (e.g. Bad IVTC, Interlacing, missing footage, bad crop,-
- commercials, bad x264 settings used, bad source, etc.) -
- - Scrolling or other alert messages added by a station (e.g. weather, -
- Amber alerts) must be at least 30 seconds in length in order to -
- nuke/proper -
- - Drops with missing footage but no missing dialog must be at least 2 -
- seconds long in any one instance to be considered a technical flaw -
- - Proper reason must be clearly stated in nfo, including timecodes and -
- extent of the flaw when appropriate -
- - Sample of propered release is encouraged -
- - Qualitative propers are not allowed -
- - Flaws (such as drops) present in any optional content are not a flaw -
- and shall not be nuked or propered. -
- - Propers based upon the rules set forth here are allowed only on -
- releases that come after this document goes into effect -
- -
- Internals: -
- - Internals are allowed to be pred for any reason, including releases -
- with technical flaws or those done with alternate codecs, containers, -
- or settings for experimental purposes -
- - Any severe technical flaws or deviations must be mentioned in the NFO -
- - With the exception of the following rule, internal releases may only be -
- nuked for severe technical flaws or deviations that are not mentioned -
- in the NFO -
- - Using DIRFIX.iNTERNAL to avoid a dupe nuke is banned, and such -
- dirfixes shall be nuked fix.for.nuke -
- -
- Directory Naming: -

- Using just the year is only permitted if the event is once per year -
- (e.g. a WWE PPV). In the case of leagues which have seasons that span -
- multiple years, it is permissible to tag the release with just the years-
- of the season. Inclusion of MM and DD is mandatory for all constantly -
- running shows (e.g. WWE). -
- If there is no league, the sport needs to be used instead -
- The following are some examples of correct directory names: -

- The Marriage Ref) must have the ISO 3166-1 alpha 2 country code in the -
- directory name, except for UK shows (e.g. The.Marriage.Ref.UK not -
- The.Marriage.Ref.GB). ISO country code is not needed for the original -
- show (e.g. The.Marriage.Ref.US is forbidden). -
- - Different shows with the same name in the same country produced in -
- different years must have the year of the first season in the directory -
- name, e.g. Human.Target.2010 and Doctor.Who.2005. Year is not needed -
- for the first show with a particular name. -
- - Channel name (e.g. National.Geographic, History.Channel) shall not be -
- tagged on any normal series starting after this ruleset's effective -
- date. Miniseries and single-episode docus may optionally be tagged with -
- the channel name. -
- - The use of audio format tags such as AAC, and AAC.x.x is FORBIDDEN -
- - READ.NFO tag is allowed; however, discretion is recommended -
- - PROPER.READ.NFO is NOT allowed. The NFO is REQUIRED to have a reason; -
- therefore, the tag is redundant. -
- - All repacks must include detailed reason as to why it's being repacked -
- in the nfo -
- - Other permitted tags are: PROPER, REPACK, RERIP, REAL, UNCUT, DUBBED, -
- SUBBED, iNTERNAL, OAR, PPV, CONVERT, NATiVE -
- - Acceptable characters in naming a directory include (NO spaces or -
- double dots - single dots ONLY): -
- -
- ABCDEFGHIJKLMNOPQRSTUVWXYZ -

- 0123456789._- -
- -
- Nukes: -
- Releases must be nuked for any of the following reasons: -
- - Any valid proper listed in the propers section -
- - Missing nfo, or missing Sample -
- - Invalid directory naming format -
- - Mislabeled directory that could prevent finding the release in a -
- dupecheck, including incorrect season/episode/date or incorrect title -
- - Dupe -
- - Releases may not be propered for bad tagging or missing nfo/sample -
- -
- Fixes: -
- - The following fixes are allowed: NFOFix, SampleFix, DirFix, SyncFix, -
- ProofFix -
- - DirFix requires NFO and NFO must state which release is being fixed -
- - The original release shall be unnuked when a valid fix is released -
- - A proper may not be released for an issue that was fixed, unless the -
- fix does not completely correct the issue -
