All clips on timeline are time compressed, project ruined

[Domarius]

I can’t reproduce this on an empty project, all I can tell you is my project file is destroyed, and all I did was add an additional clip to the end of the time and change its speed.

I added one new clip to the end of my timeline, and set its speed to be 10x faster, in the properties dialogue. Soon after I had already saved multiple times, I realised every single clip in the timeline had been sped up, even though they are from completely separate video source files and sound files. This has ruined all of today’s work, since there is no way to undo this mess. So many carefully timed sound effects and video clips, all ruined.

I can’t even work from the project file to resurrect it, as even the clips I drag from the playlist, seem to have been permanently shortened. I have to go back to a previous project file.

Clips shrinking in timeline

I’ll just simplify the description. I had clips “A”, “B” and “C” to add to the timeline from the playlist but “C” was to be played at 4x. I added “A” to the timeline, I changed the playback speed of “C” to 4x and added it after “A”. I realized that I should have added “B” then 4x “C” so I removed (right-click Remove) “C” from the timeline, then added “B” and then changed “C” to 4x and added it. When I played the timeline, “A” had been shortened significantly even though I hadn’t touched it aft…
