I am currently using the v 3.32.
When I view the video fro the editor preview, everything is fine but when I export the video, the sped up parts are too fast then they suddenly freeze until the clip of the video.
The audio remains constant, it's just the video that is messing up.
I've tried changing the resolution, different file formats, switching the video encoding and even moving the whole project file and original move file to a new location.
TLDR : Fine in editor preview, but when the video is exported, the sped up parts are TOO FAST, then they freeze until the next clip starts while the sound remains intact.
