What's in your mp4s. Where did they come from?

with youtube downloaders, you'll often get 2 different mp4's now at each resolution for 1080p and below which can be confusing if the downloader has not been updated recently to show the difference. They will normally show you file size, AVC is the larger size which is compatible with vegas, AV1 the smaller size and not compatible.
Not saying you dont' have a technical issue but coincidentally you could have downloaded an AV1 in error to use with Vegas straight after the upgrade

Try restart system after update and see if that can solve the issue. Few times little weird thing can happened directly after updating.

As I mention in a different thread, I was able to open MP4 files in build 452 after disabling So4 compounding for AVC/M2TS in Internal preferences.

Going back to 421 fixed it for me. Glad there's a real solution - thanks, Robert.

I had lots of strange stuff going on after the upgrade, like my video rendering upside down. Had to do a full reset, and now renders correctly. Hold control-shift down while opening, and clear everything.
