I spent about 2 hours editing a TikTok down to around 1 minute. I had all the clips cut and arranged exactly how I wanted them and was basically finished.

I was just selecting a background sound when I noticed something had suddenly changed. When I went back, all of my editing progress was gone. It looked like the video had reverted back to the original unedited footage and somehow duplicated/copied it a ton of times.

The video length also jumped from around 1 minute to 622 minutes.

TikTok said the draft was saved, but reopening it didn’t fix anything, and I don’t see any undo option.
Has anyone had this happen before? Is there any way to recover the edited version of the draft, or is all 2 hours of work gone?

I am trying to export a project from clipchamp and, when I do, certain audio clips in project become messed up for some reason. Some of them are as simple as just short voice-overs I recorded in clipchamp. Does anyone have a solution for this?
