Cutting a some video shot on a handful of GH4s shot in 4K for 2K delivery after a color pass in Resolve. My basic question is, what should my working timeline be? 2K? 4K? I do plan to do some reframing and resizing, my computer can easily handle the 4K video. If I blow up the footage in a 4K timeline to 200% but eventually delivering to 2K (where it would, in fact, be 100%) will it have an adverse affect compared to starting off in a 2K timeline? My producer is a bit of a quality freak so want to be sure I cover my bases.
Cut in a 2K timeline and reframe as needed. As you cut clips to the timeline use "set to frame size" (not "scale") to fill the frame. I'm not exactly sure how the GH4 handles TC, but in my experience, round-tripping to Resolve with any DSLR footage can be - and usually is - a relinking disaster. If you plan to cut natively, then export a flattened, single file and then blade it at the cuts in Resolve. The preferred approach would be to convert all of the GH4 files to an editing format like ProRes or DNxHD/HR first. Make sure these have proper TC and unique file names. This will assure that Resolve properly relinks.
