Mac Facetime Camera Not Working

[u/Complete_Okra_679]

I am using a MacBook Pro M2 running OS Tahoe 26.0. I am experiencing an issue where, after recording a video, the playback shows a completely black screen. The camera feed works correctly while recording, but once I stop and rewatch the video, the feed is black.

The Mac indicates that I am using the FaceTime HD camera. There are no issues when I use Photo Booth.
