later there was a revision that fixed some examples. The MKV container must be used. It is mandatory to support file streaming and playing from RARs. CRF must be used. A photograph as proof must be included. 81 groups signed the document. x264 for television sources On February 20, 2012, more than a year after the appearance of the first draft, the SD x264 TV Release Standards document was released with the goal to bring quality control back to the SD releases. According to the document x264 has become the most advanced H264 video encoder and 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 (constant rate factor) in the mix it can be ensured that a diverse array of material will get the most appropriate bitrate and not arbitrary fixed file sizes. The video container must be MP4 and AAC is used for the audio. Thirteen groups, ASAP, BAJSKORV, C4TV, D2V, DiVERGE, FTP, KYR, LMAO, LOL, MOMENTUM, SYS, TLA and YesTV signed the document and began releasing TV shows in the new format. FQM and 2HD indicated they will keep releasing XviD. FQM said it's pointless losing a lot of standalone compatibility for slightly higher quality when there's already even better quality available. 2HD agrees and a vocal minority of the torrent community is quite upset because the MP4 container isn't compatible with many DVD players and other devices, but most scene groups don't really care about BitTorrent. Softpedia writer Lucian Parfeni called this interesting phenomenon the angry pirate and wrote that a lot of BitTorrent users are very disappointed about the move, though quite a few have no idea why it happened. A second reason FQM provided was that partial files can't be played back but LOL wrote the next day that the streaming issues were solved. On March 29, an updated version of the rules were released. This time 22 groups supported the document. MP4Box became the recommended muxer because it has support for file streaming and playing from RARs. For encoding audio, FFmpeg and FAAC encoders are banned. 2HD announced on April 15, 2012, that they would be abandoning XviD as show seasons end, but later this changed to only the seasons of the bigger shows. A month after 2HD's first announcement FQM released their first x264
