I am trying to roundtrip a Premiere project to Resolve and back. My method was to export the Premiere project as an AAF, then imported that into Resolve. I deleted all the audio (we did sound before color, and the transcoding to AAF couldn't bring the audio effects along with it) and completed the grade. I exported the timeline from Resolve as a Premiere XML (as individual clips with 120 frame handles). I then brought that exported xml into Premiere and pasted it into my timeline with the original clips. I'm going through one-by-one and re-syncing the clips by hand, but I'm wondering if there's a tool analogous to Merge Clips that analyzes image frames instead of audio waveforms.
I'm also open to a better way to roundtrip, I found this workflow through YouTube videos and trial and error.
