I'm exploring the possibility of capturing the HD-SDI signal live from a Red One as it's recording, via an AJA IoHD, and using 'log and capture' ('capture now') to get that into FCP, so we can have a fast on-set preview. Ideally we'd be able to make a very rough cut on-set because we're able to identify the (parts of ) takes we like. This would mean that later when we ingest the r3ds and transcode them to ProRes for the online edit we could reconnect the media (based on time code) to the rough edit performed on-set. Is this possible?? Obviously the file names of the AJA-captured footage would be different (unless we name them on set, which I suppose is possible) to the r3ds, but it seems to me that the key is whether the timecode is the same on both sets of footage??
