- 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.                                    -

-   - 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 -

-   - "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. -
-                                                                             -

-   - 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                 -
-                                                                             -

-   - 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.                  -

-   - Stripping or falsifying encode information in the file header is banned -
-   - Custom  muxing  tools are permitted; however, output must be compatible -
-     with standard demuxers.                                                 -

-   - 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).                    -

-   - 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       -

-   - WS HDTV and WS PDTV sources with greater than 720px horizontal res must -

-   - 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)-

-     of the season. Inclusion of MM and DD is mandatory for all constantly   -
-     running shows (e.g. WWE).                                               -

-   - 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 -
