I have a similar question. I have a timeline ttyat is 75% 4k footage, 25% HD (GH4 96fps). My destination is HD. Should I also work in a 4k timeline and scale up my 1080 or the opposite, work in 1080 and downscale the 4k? Also, if anyone can clear up a workflow issue it would be a huge help. In the above project I have nested and warp stabalized various 4k clips. The edit is complete and now I need to send to Resolve to grade. When I export as is the nesting and scaling messes it up when they come back into Premiere—the 4k clips are scaled to 50% of 1080, not 50% of 4k. Do I need to undo all speed, scaling, and warping in a duplicate timeline, send to Resolve, then reapply when to are back in Premiere?
