My big problem with Tahoe, is the lock screen animation stutters and freezes CONSTANTLY. I'm on an M3 Pro. If I can watch 4K video with no dropped frames, a simple video background should work as well, and if it doesn't, it shouldn't exist.

I have this problem a few times a day on my corporate M4 Pro when I lock the screen... with 60Hz set. It happens when the two security monitoring app corporate insists on are scanning harder b/c the screensaver kicked in. My personal macbook pro is fine.

Are you using a Studio Monitor? Lock screen videos are incompatible with Settings > Displays > Refresh rate > Adaptive. You have to use a fixed frame rate (60 or 120 Hz).
