I recorded a 2-hour webinar because Microsoft Teams won't allow a download. I used Soundflower and Quicktime screen recording. At the end, when I wanted to save, I saw
I tried a few more times and could not save it. I could export it with a different resolution and decided against it since it would take a lot of CPU time. I found the raw file at
~/Library/Containers/com.apple.QuickTimePlayerX/Data/Library/Autosave Information/ (source). I showed the package contents of the
.qtpxcomposition file and saw the 11.7 GB
.mov recording in it.
It plays alright for 25 minutes and the audio is OK throughout. After 25 minutes, the video frames freeze both on VLC and on QuickTime. If I navigate to the end, I can see new frames, so I'm sure that it's not my screen that froze. Obviously, the size of the file indicates that a lot of the frames were saved, but I can't find how to play them.
How can I view this recording, or how can I re-record again properly?
