So first of all, happy Christmas everyone, it’s a rough start for me unfortunately and was hoping someone here could maybe provide some more insight.

So I use a M1 macbook air on the latest MacOS, and had about 400GB of footage stored on an external SSD. I recently purchased a new external SSD so I copied the entire 400GB folder over to the new SSD. It appeared to have copied over successfully, so I deleted the original copy from the original SSD.

I first noticed issues when my iMovie projects weren’t exporting and were throwing errors due to corrupted frames. I noticed when playing back the iMovie projects, there are loads of skips in the videos showing black frames. I thought this was just an iMovie issue, I also moved my iMovie library across to the new SSD.

I then noticed that when trying to play any of my original source video files from the new SSD, these skips and stutters in the video are still apparent. Happens in Quicktime and VLC. In Quicktime the videos stutter, and in VLC there are loads of visual artifacts in the videos. The audio continues to play fine, just issues with the video playback.

I am unable to edit with any of this footage due to these corrupted frames. I’m actually devastated, this was years of personal footage which is can’t just replace.

Is there anyway to salvage this? Any ideas what may have caused this in the first place and how to prevent it happening again?
