I tried to add other xavc classes as mp4 profiles (see attached patch, do not forgot to make install after patching), but without altering bt709 x264 params line - may be we should comment it so it can be overridden by bt2020 colorimetry?
also, those does not set flavor sony, may be they should? I also try to develop xavc mxf profiles on desktop (those are from Termux, 3 fps encode at FHD ;) вт, 22 апр. 2025 г., 00:54 Andrew Randrianasulu <[email protected]>: > In attempt at speeding up hdr10 4k HEVC video playback I tried to > re-encode it into AVC-intra using this guide: > > > https://www.voukoder.org/forum/thread/1163-replicate-sony-s-xavc-i-s-format/ > > basically either > > ffmpeg -i input -c:v libx264 -avcintra-class 480 -pix_fmt yuv422p10le > -preset ultrafast -x264opts avcintra-flavor=sony -c:a pcm_s24le -ar > 48k output.mxf > > or for half size > > ffmpeg -i ~/K38_sdcard1/Documents/iPhone11_4K-recorder_59.940HDR10.mov > -s 1920x1080 -c:v libx264 -avcintra-class 200 -pix_fmt yuv422p10le > -preset ultrafast -x264opts avcintra-flavor=sony -c:a pcm_s24le -ar > 48k output-half.mxf > > Note, line errors out when I tried class 480 for 1920x1080 frame size > > Both files load into cingg > > Original file (4k hdr hevc, 59.94 fps) plays at around 22 fps at > output x11, project rgba-float.
