It does record fine when using un-accelerated H264, so I’m pretty sure gdigrab isn’t at fault.

Regarding the quality loss: Then apparently, ffmpeg's encoding defaults are too low for your material. You need to choose a higher bitrate or encoding quality: https://trac.ffmpeg.org/wiki/Encode/VP9#constantq (Assuming your ffmpeg supports and therefore uses libvpx-vp9.

[FFmpeg-user] Rotating webm videos
Hello, I am trying rotate some webm videos by 90 degrees, ideally without re-encoding. I tried this command: ffmpeg -i input.webm -vf “transpose=1” -t 20 output.webm But this re-encodes the video (slow) and there is noticeable quality loss. I also tried this command (which works for mp4) which does not re-encode but sets flags in the metadata: ffmpeg -i input.webm -c copy -metadata:s:v:0 rotate=90 output.webm But this does not do anything (I verified output file is identical to input). My video was downloaded from youtube with the following command: youtube-dl https://www.youtube.com/watch?v=1Qsxj-B1UPk -f 313+171 Any ideas?
