Splicing a DCP (insert edit)
Posted: Sat Sep 07, 2019 2:04 am
Couldn't find here a discussion about making small edits to an existing DCP. I'm talking about instances where a DCP has been created, but the film's producers want to change a few seconds in the middle. Without reels and CPLs, just patch an existing reel.
Since a DCP is an MXF with a series of intra-frame J2K frames, it's completely doable (correct me if I'm wrong).
One way to implement this is outside of DOM, which could work if one renders the J2K frames externally. But we know that this is a tricky thing, and it's better to trust DOM's J2K conversion.
So I see it as big feature request (a boy can dream)... supply a matching piece of source video, accurately define the splice point, and be able to verify it. (Audio is a slightly different beast - may need the ability to add 1ms crossfades to avoid pops, or just redo the audio track since they're much smaller and faster to work with.)
What do you think?
