  4. - The SD x264 TV Releasing Standards 2012 -
  5. LTTTT-

  7. - L[ INTRO ]- -
  8. - -
  9. - x264 has become the most advanced video codec over the past few years. -
  10. - Compared to XviD, it is able to provide higher quality and compression at -
  11. - greater SD resolutions. It also allows better control and transparency over -
  12. - encoding settings. With CRF in the mix, we can also ensure that a diverse -
  13. - array of material will get the most appropriate bitrate for them and not -
  14. - arbitrary and fixed sizes. This standard aims to bring quality control back -
  15. - to SD releases. There are many standalone players/streamers such as TviX, -
  16. -Hour, WDTV HD Media Player, Boxee, Xtreamer, PS3, XBOX 360, iPad, & -
  17. - HDTVs that can playback H264 and AAC encapsulated in MP4. -
  18. - -
  19. - The SD x264 TV section was formed to separate releases from the ruleless -
  20. - world of TV-XviD. This document will cover the rules and guidelines for -
  21. - only SD resolution x264 television rips. -
  22. - -
  23. LTTTT-

  25. - L[ RELEASE RULES ]- -
  26. - -
  27. - Compliance with this document is optional as of its pre date, and -
  28. - mandatory as of 2012-02-22 16:00 UTC. -
  29. - -
  30. - Video: -
  31. - - Sources requiring resize are to be cropped and resized using sharp -
  32. - resizers such as Lanczos/Lanczos4, Spline36, or Blackman. Bicubic is -
  33. - banned. -
  34. - - HD video taken from the decoded HD output of a set-top box (e.g. -
  35. - component, DVI, HDMI) may be used as a source; source must be tagged -
  36. - in dirname as AHDTV. Decoded output of PDTV or DSR sources is banned. -
  37. - Releases taken from a natively recorded transport stream shall be tagged-
  38. - as HDTV, PDTV, or DSR. Dupes are as follows: HDTV > AHDTV > PDTV > DSR. -
  39. - AHDTV captures must be done at the native format of the channel, e.g. -
  40. - 720p or 1080i. -
  41. - - Sources that sideconvert 1080i to 720p (such as BellTV) are allowed but -
  42. - must be tagged as PDTV or DSR. -
  43. - - If there is a question as to the validity of a source, the release -
  44. - may be nuked source.sample.requested_<reason.for.nuke> (e.g. -
  45. - source.sample.requested_suspicion.of.analog.source) within 24 hours of -
  46. - pre. The group has 24 hours from the nuke to pre a RARed SOURCE.SAMPLE -
  47. - that is at least 10 seconds in length in order to document that the -
  48. - source is valid. Failure to provide source proof or providing bad -
  49. - source proof shall result in the release remaining nuked, and it may -
  50. - then be propered. -
  51. - - Improper IVTC methods that result in jerky playback, such as Force -
  52. - Film, are banned -
  53. - - Interlaced video sources must be deinterlaced with a smart deinterlacer -
  54. - such as Yadif. FieldDeinterlace is banned. -
  55. - - Group watermarks of any kind on the video are banned -
  56. - - Intros, outros, betweenos, or any other form of defacement of the -
  57. - episode are banned -
  58. - - "Native" refers to the standard in which the video was produced (e.g. -
  59. - NTSC or PAL). NTSC produced video is native to NTSC, PAL produced video -
  60. - is native to PAL. PAL produced video that is broadcast in NTSC is -
  61. - converted. NTSC produced video that is broadcast in PAL is converted. -
  62. - - Converted video that has significant artifacting (e.g. blended frames) -
  63. - and cannot be reversed to native must use CONVERT tag -
  64. - - Converted video that does not have significant artifacts does not need -
  65. - convert tags and may not be nuked for the conversion -
  66. - - Native releases are allowed after those tagged CONVERT. Use NATIVE tag. -
  67. - -
  68. - Audio: -
  69. - - Allowed audio formats are VBR AAC LC (Low Complexity). -
  70. - - Average bitrate on AAC audio must be 96 - 160 kbps. -

  73. - - Dupes based on audio format are forbidden and must be tagged INTERNAL -
  74. - - Multiple language audio tracks are allowed and must be listed in NFO -
  75. - - Dupes are not allowed based on multiple audio tracks -
  76. - - Severe audio drops resulting in one full missing word or otherwise the -
  77. - inability to understand material dialogue is considered to be a -
  78. - technical flaw and may be propered -
  79. - - Audio that is 120ms or more out of sync or drifts more than 120ms -
  80. - between any two points (e.g. needing -80 at one and +40 at another) is -
  81. - considered to be technically flawed and may be propered -
  82. - -
  83. - Framerate: -
  84. - - IVTC or deinterlacing must be applied as needed -
  85. - - 50/60fps video may be released at 50/60fps or 25/30fps. Releasing true -
  86. - 25/30fps video at 50/60 is considered a technical flaw. -
  87. - - In rare cases, 25/50Hz sources should be IVTC'd to 24 or 30 fps. -
  88. - - In rare cases, 30/60Hz sources should be IVTC'd to 25fps. -
  89. - Failure to apply IVTC when needed is a technical flaw. -

  98. - with standard demuxers. -
  99. - - Custom Matrices are allowed -
  100. - - Encoded colorspace must be 4:2:0. -
  101. - - Deblocking must be used; values are at the discretion of the group. -
  102. - (default is enabled, 0:0 settings) -
  103. - - No setting can go below what is specified by --preset slow. -
  104. - - Keyframe interval (--keyint) must be at least 200 and at most 300. It -
  105. - is recommended to be 10*framerate (film=240, PAL=250, NTSC=300). -
  106. - - Minkeyint must be 30 or less -
  107. - - Colormatrix must be set to source specification. If not specified by -
  108. - source, bt709 must be used for sources with resolution greater than or -
  109. - equal to 1280x720 (e.g. HDTV and some PDTV) and sources with lower -
  110. - resolutions must use bt601 (e.g. DSR and some PDTV). -
  111. - - Constant Rate Factor (--crf) must be as follows: -
  112. - -TT -
  113. - - Compressibility - CRF - General Examples - -
  114. - ++++ -

  121. - - Zones (--zones) are forbidden. -
  122. - - Any deviation in CRF from given examples must be specifically justified -
  123. - in the NFO. Use discretion when deviating CRF by matching the -
  124. - compressibility of the show to a corresponding CRF value. CRF values -
  125. - below 19 and above 24 are never permitted. -
  126. - - As a general suggestion, average video bitrate in excess of 1500kb/s -
  127. - is a sign that a higher CRF value should be chosen, when possible -
  128. - - Allowed parameters for --tune (optional) are film/grain/animation -
  129. - - Level 3.1 must be respected. -

  144. - black or other colored borders, duplicate lines, and full-time tickers. -
  145. - Removing or retaining fading edges is at capper's discretion and shall -
  146. - not be considered undercropped or overcropped. -
  147. - - In the case of varying crops, crop to the most common frame size (e.g. -
  148. - pitch/primary view in sports). -
  149. - - Actual picture area may be over- or under-cropped by 1px maximum per -
  150. - side. More than 1px on any side is considered a technical flaw. -
  151. - - Encoded Video resolution must be within 2% of the original aspect ratio -
  152. - To calculate AR error (%): (Original AR - Release AR)/Original AR * 100 -
  153. - OAR = (SourceWidth-CropLeft-CropRight)/(SourceHeight-CropTop-CropBottom)-

  272. - 0123456789._- -
  273. - -
  274. - Nukes: -
  275. - Releases must be nuked for any of the following reasons: -
  276. - - Any valid proper listed in the propers section -
  277. - - Missing nfo, or missing Sample -
  278. - - Invalid directory naming format -
  279. - - Mislabeled directory that could prevent finding the release in a -
  280. - dupecheck, including incorrect season/episode/date or incorrect title -
  281. - - Dupe -
  282. - - Releases may not be propered for bad tagging or missing nfo/sample -
  283. - -
