Sadly ffmpeg doesn’t yet support the HapQ Alpha format.Hap Alpha requires straight alpha (not pre-multipled).You can also add the -chunks 4 option which will encode each frame into 4 chunks so the decoding work can be split across multiple threads, resulting in faster decoding as long as the disk can keep up.ffmpeg -i input.mov -vcodec hap -format hap_q output-hap.mov.ffmpeg -i input.mov -vcodec hap -format hap_alpha output-hap.mov.Jokyo HAP Ae Encoder is now optimized for the new After Effect CC 2022.3 on. ffmpeg -i input.mov -vcodec hap -format hap output-hap.mov We are proud to announce the release of the HAP codec encoding plugin for.In 2020 Jokyo introduced their fast and high quality Hap encoder with plugins for Adobe After Effects, Premiere Pro etc: FFMPEGĪlternatively you can use a recent build of FFMPEG with the following command-lines: Ideally a width with a multiple of 16 is best for performance (aligned copy). Width and height must be multiple of a 4 for Hap encoded videos in AVPro Video. Hap, Hap Alpha, HapQ, HapQ Alpha and HapR are supported. Amount of frames to decoder before starting playback, less frames for less latency in seeking, more frames for less chance of buffer emptying too quickly.Less threads for less latency in playback operations (seeking, playing etc), more threads for better performance. Another option would be to encode Hap files using ffmpeg, using the following command line: ffmpeg -i inputfile.mov -vcodec hap -format hapq -chunks 4 outputfile.
