I appreciate it! To answer your question, the majority of footage (I’d say 80%) is being shot at 4K , while the rest might be a hodgepodge of 720p, 1080p and still photos. What’s trickier is some of the lower res material I would probably want to reframe which means zooming in and recropping (beyond the upscale to 4K).
In these situations is it preferable to work at the deliverable resolution instead?
