I figured out a fix for DVX codec in adobe on a Mac M1. Go to after effects or premiere and right click on thew application and check "open in Rossetta" then open AE or Premiere , it takes a while to open the app but it will open eventually.
Cheers!

Because it's not clear on this site, I thought I should post this. The upgrade to 7.5 is 99% wire upgrades. So if you don't want to drop $469 on Wire, the upgrade cost of $235 bucks per computer is worthless.
