I just did a screen recording with Quicktime Version 10.4 (928.13). After i tried to save the video, "Cannot open" popped up and I followed the method described in this link “cannot open” when trying to save screen recording in quicktime player. So I was able to retrieve the screen recording.

However, the video only captured around first 20 minutes, and audio works fine. Say the whole video is 2 hours, but if I drag the time line after 20 mins, the video will stop at same frame and it would never change.

I have enough spaces on my mac (95GB is available).It is third time that it's happening to me. Any suggestions/workaround will be greatly appreciated.

Quesition: Is there a way I can restore the whole video since current video only works up to 20 mins, and rest of it is all audio only.

  • And your question is about what exactly? – nohillside Jul 15 '18 at 8:13
  • My question is about how I can restore the video. Since the video part is only 20 mins, rest of them is just audio. – user7672 Jul 16 '18 at 14:50
