Random postponement of every clip in project

[Ashar61]

I have to correct myself. I see now that all videos just shifted randomly not exactly for 3 seconds but just randomly. I saw another post here of someone who had the same issue. Why is something like this happening?

Randomly EVERY clip in timeline is trimmed differently than when they were inserted

I have a nearly finished project with 50+ clips in it. I HAD every clip’s beginning and end trimmed perfect, but all of a sudden, I realize every clip in the timeline is trimmed different by a few seconds from how I trimmed them. This essentially ruined the entire project. Some clips are cut short at the end. Some have extra at the beginning that I had previously trimmed off. I don’t know if maybe I accidentally hit something or what. While editing, I’ve obviously reviewed the timeline/project …

Its just so devastating.
