4 years ago For now, the script captures a 1080x720 video which is then cropped (to remove the firefox window that plays the video).
You can try changing the resolution of the captured video in capture-full-replay.sh line 111:
diff --git a/capture-full-replay.sh b/capture-full-replay.sh
index c16ec7e..59a1ff3 100755
--- a/capture-full-replay.sh

In case you want to capture only the main screen, I'm not sure how to compute its width.

Thank you very much. Can I set higher resolution and h.264 main profile? After a download I have only 520 pixels like vertical resolution and I can open the file only with vlc (due to high 4:4:4 profile). I can convert them manually with commamd "ffmpeg -i input.mp4 -profile:v main -pix_fmt yuv420p out.mp4" to solve the issue, but can you do anything while downloading?
