I think that it could be done, but we need more sofisticated specification for the full task. Could you please prepare it in more detail from the very beginning till the end? We will probably be able to generate proxy .mp4, .wav and full-frame .dng series at the same time.
Here are some questions:
1. If we choose new start and stop positions for CDNG series, which time code we need to write to CDNG file at start position? Is it zero or not? The same question for CDNG file at stop position – which time code should be there?
2. If we choose correct start and stop positions at CDNG series, what we have to do with audio file? Should it be truncated according to start and stop coordinates?
3. I don't think that we need to do anything with black frame series because we will choose start and stop positions manually. Is it correct?
QuoteWhat could be improved with fast cinema DNG ?
1) generate ProRes Proxy via FFmpeg with a script that timestamp the same TC on proxy than on the MLV. Most cameras cannot generate proxy mlv in the same time (all except 5DmkIII) + script for 5DmkIII that correct black off frame from proxy & timestamp same tc on proxy than MLV
2) a system to generate on the fly CDNG with GPU rendering to speed workflow with resolve ? Or if not possible, generate CDNG that maintains the same TC and synch them to the proxy file (H264 or prores proxy)
