Hey I had this problem and here’s what I discovered:
I was editing in Premiere Pro raw R3D files shot on EPIC RED with Anamorphic lenses then exporting an XML for Davinci Resolve Lite.
When I imported the xml some clips came up offline or jumbled in the timeline. Davinci was crashing evert time I put the playhead over them.
I went back into Premiere Pro and found in my edit I had used files that came from the red that appear to be doubles of some of the takes only difference was the smaller file size. For example I got files called “A004_C008_0215V0_001.R3D” and “A004_C008_0215V0_002.R3D” in the same folder.
In Premiere Pro I replaced the “_002.R3D” ones with the larger “_001.R3D” ones and this solved the Resolve issues. I think Premiere Pro can handle it but Resolve maybe can’t or skips them thinking they are doubles then pulls other clips at random because I got heeeeeeaaaps of weird shit where it wasn’t supposed to be in my edit.
Dunno if this helps you but may hel someone else shooting on Epic..
