I'm using dynamic link in premiere pro to create a composition in after effects to combine a green screen layer and a background plate. Done this many, many times with no issues. However, I decided to tackle an older project that had been sitting around, and when choosing "replace with an after effects composition" in premiere pro, after effects opens a project oddly where the green screen layer is indeed a mov file, but the background mov file is already a comp. So my project now contains a newly named comp (the one replacing the clips), the green screen mov file, the background mov file and a comp containing the background mov file. In the timeline are the green screen mov file and the background "comp".
The background file is clean. Why might this be happening? Thanks.
What is the exact version of AE you are using?
Same question about Premiere.
What codec is the MOV?
