I’ve encountered the same problem. I’ve been experimenting with using Davinci Resolve to us Scene Detection to break up a video into small chunks to edit in premiere. I export the cut timeline from Resolve as an xml and import it into Premiere/After Effects and the source footage is shorter than Resolve says it is by about 1 second. The timecode is different. I’v been messing with this all day.
At first, I thought it was a Variable Frame Rate Issue. After running it through Handbrake, there is no change. The problem persists. I’ve tried different frame-rates as well.
Currently, I’m using Media Encoder to create a new source for Resolve’s Scene Detection. If it works, it may confirm that the problem is with Adobe. Which would bring relief that I know the problem, but sadness that this problem exists. I remember using AME earlier today and I think I had success, but did not realize what exactly “fixed” the issue. I’m not sure it did. I will find out though. I don’t have another NLE to rule out it’s not premiere.
I can import the xml back into resolve without issue. The xml itself, near as I can tell, is fine.
If it is Adobe, I hope it can be resolved soon.
