Build the conform
Once analyzed, the Handoff options unlock.
Add markers, include audio, color clips by severity, open the Review window after import, and optionally print an issues PDF. Grading-layout options control nested sequences (embedded timelines vs flattened) and whether to collapse tracks for a straight full-frame grade. To ship only the frames the edit uses, turn on trimmed media.
If you'll bring the grade back, turn on Premiere Pro roundtrip and pick a delivery codec (ProRes / DNxHR). On the way back only the graded picture is swapped — audio, graphics and other media rebuild from your originals, so keep them on disk. The way back is the return trip.
