Description jaytaygame 2021-01-18 22:05:38 UTC

SUMMARY
The audio on long videos speeds up really fast and then stops playing.

The video is 2hours 1minute 36seconds long and this problem occurs around 1hour 37minutes 40seconds. If the video is played before that time and into after, the audio is normal until its paused and then played again.
All videos added after do not have the audio sped up, unless they are longer than that 1hour 37minutes, then the audio is normal until the ~1hour 37minutes length

After rendering the project, the audio playback speed is normal.

I have verified that the original video clips do not have any audio problems.


Windows 10 version 1909
