Description Ivan 2023-05-16 18:47:50 UTC
I made a video with several video fragments at 1000x speed. Rendered with MP4 - mainstream (H264/AAC). After rendering, I found that the audio started to delay from some point for a couple of seconds, and the beginning of the normal speed fragment cuts audio right after speeded fragment.


STEPS TO REPRODUCE
1.  Add video fragments
2. Make several of them in the middle with 1000x speed
3. Render to MP4 - mainstream (H264/AAC)
