Thank you that workaround partially works. Unfortunately the VideoEncoder api doesn't support transparency/alpha recording. https://chromium.googlesource.com/chromium/src/+/00d126142a32c598a0874ef80ba27a3591cd2b2c/third_party/blink/renderer/modules/webcodecs/video_encoder.cc#190 The MediaRecorder API does support transparency, however to make it work, it would need a better frame by frame api. So currently, if you want to create a transparent video, you either have to record in real time using the MediaRecorder API or use the VideoRecorder API and use ffmpeg with a Chrome key to add transparency in a second pass. -- GitHub Notification of comment by SamuelScheit Please view or discuss this issue at https://github.com/w3c/mediacapture-record/issues/213#issuecomment-2917765410 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
