Hi there,
Unfortunately there's no way to automatically detect these changes within Premiere. Usually this task needs to be manually tracked by whomever is doing the post work so that the exact spots can be noted and commnicated with the team.
That said, here are a couple of options you can try in order to find the changes yourself:
- Lay one version on top of the other in a sequence and reduce the opacity of the top video to 50% (make sure they both start on the same frame). You won't notice any difference UNTIL there's a different cut and then you'll see sort of a ghosting image as the two videos will be out of sync.
- Put both videos in a sequence just like above and use "scene edit detection" to identify where the cuts are. Premiere will put edit points where it detects cuts and these should align in both videos -- until there's a different edit and the lines misalign. Note that this method may not be 100% since scene edit detection might miss a cut or two.
Note that in either case, once you detect the first change you'll have to move/slip the entire video segement until it's back in sync so that you can identify the second change. since after the first change the rest of the video will be out of sync.
HTH,
