Re: [FFmpeg-devel] Avid DNxHR / UK DPP
Gentlemen, I'm at DPP conference, in the room. Start of UHD delivery standards for UK just announced. Now on website, we are told. H.264 codec, AS-11 encapsulation for MXF, HLG and SMPTE 2084 both supported for HDR, WCG framework supported, Long-GOP in H.264. But I-frame only option for post-delivery requirements. Tests to be done on high frame rate, live delivery and object-based audio. ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel

Thanks for letting me know. I read your reverse-engineering saga. At the moment, the DPP workflow guidance is codec-agnostic and does not involve delivery specifications. My influence is probably negligible (and I do not speak for them at all) but I'll do my best to encourage delivery codecs for which source code is readily available under an open licence and in FFmpeg e.g. VC-2. ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel

[FFmpeg-devel] Avid DNxHR / UK DPP
Tomorrow I'm attending an event run by the Digital Production Partnership, a body that has brought together mainstream digital television delivery and workflow standards for UK broadcasters. My production company is a member, and we assisted a little in the development of their UHD workflow document. If you don't already have a line of communication open to them, I'm asking you if there is anything you would like mentioned to them about UHD codecs in FFmpeg e.g. DNxHR development and assistance in the process?
