│                                                                             │
│ 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.                                    │

│                                                                             │
│  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:                        │
│     ┌─────────────────┬───────┬───────────────────────────────────────────┐ │
│     │ Compressibility │  CRF  │ General Examples                          │ │

│     └─────────────────┴───────┴───────────────────────────────────────────┘ │
│   - 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:                                                 │

│  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                              │

│   - 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.                                                  │

│   - Show.Name.YYYY.MM.DD.Guest.Name.HDTV.x264-GROUP for daily or other      │
│     dated shows                                                             │
│   - Episode title and guest name are optional                               │
│   - Show.Name.PartXX.HDTV.x264-GROUP for miniseries                         │
│   - ALL others are FORBIDDEN. (e.g 0x00 000 EXX.EP.TITLE PART.VI)           │
│     Sport:                                                                  │

│     - Competition.YYYY-MM.Event.EXTRA.TAGS.HDTV.x264-GROUP                  │
│     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:             │
│     - EPL.2010.01.01.Manchester.United.vs.Arsenal.HDTV.x264-GROUP           │
│     - TNA.Impact.2010.03.02.HDTV.x264-GROUP                                 │

│     - Tennis.US.Open.2011.Final.Player1.vs.Player2.HDTV.x264-GROUP          │
│   - Different  shows  that have the same title in different countries (e.g. │
│     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 │
