#EDITREADY AND CONVERTED IT TO PRORES 422 SOFTWARE#There you have it, a simple way of using FFmpeg to convert videos into Apple ProRes 422 or ProRes 4444 formats.Earlier in the summer, Divergent Media, a software company whose tools need no introduction in the video production world, released EditReady, a Mac transcoding app with a tremendous claim, that it was supposedly the world's fastest transcoder for Quicktime conversion. Apple ProRes 4444 profile is being used.The commandline is same as above, but, you would change the pixel format as follows – yuva444p10le to indicate to FFmpeg to use 4:4:4 chroma subsampling with 10-bit bit-depth. FFmpeg to Convert to Apple ProRes 4444 Format ffmpeg -i inputVideo.mp4 \ ![]() And, the profile is 422 HQ and the FourCC codec ID is apch as expected. It clearly shows that the “writing library” is recognized as “Apple”. Also, FFmpeg reports that the variant is prores (HQ).Īnd, here is the output of MediaInfo. It shows that the chroma sampling and bit-depth is 4:2:2 10-bit. #EDITREADY AND CONVERTED IT TO PRORES 422 MP4#mp4 file and then inspect the file using ffprobe, here is what I get. We also tell FFmpeg to use 4:2:2 10bit chroma subsampling and bit-depth.ĭo remember to store the output in either of these three formats that are allowed as containers for the ProRes format.

If we were to change that to 2, it would be the standard ProRess 422, and so on. If you see the commandline, we’ve used -profile:v 3 to choose Apple ProRes 422 HQ variant using FFmpeg. The commandline for Apple ProRes 422 (HQ) encoding is pretty straightforward using the options above – ffmpeg -i inputVideo.mp4 \ Encoding Apple ProRes 422 HQ using FFmpeg Specify number of bits for alpha component. A custom vendor ID like apl0 would claim the stream was produced by the Apple encoder. Number of macroblocks in each slice (1-8) the default value (8) should be good in almost all situations. Different profiles use between 2 bits per macroblock, the maximum is 8000. How many bits to allot for coding one macroblock. If not set, the matrix providing the highest quality, default, will be picked. If this option is set to auto, the matrix matching the profile will be picked.
