I just use VideoEncoder of Webcodecs API provided by Safari 16.4 to encode video, The quality of the encoded video is poor on Mac Safari but it is normal on other platforms such as Mac Chrome, iOS Chrome, iOS Safari, and Android Chrome. Video samples: https://chillin.online/images/webcodec-sample-mac-safari.mp4 https://chillin.online/images/webcodec-sample-mac-chrome.mp4 More Details: The quality of video seems to decay over time, I find this bug on mac based on Intel chip, The VideoEncoder config is const config = { codec: 'avc1.640034', width: 1280, height: 720, framerate: 30, hardwareAcceleration: 'prefer-software' as const, avc: { format: 'avc' as const } }; Looking forward to your feedback on this bug, my email is chillineditor@gmail.com.

Can you share reproducible test case so we can try to reproduce this issue in newer versions? Please can also share if this is fixed in Safari Technology Preview?
