Duplicate First Frame on Edit to Tape
We have a client in who is crossconverting a 90min 720p23.98 show to 1080psf23.98 HDCAMSR using the Kona 3 card and FCP 6.0.3 with Quicktime 7.5 (149).
The issue we are seeing is that when trying to do a frame-accurate insert edit, we get a duplicate first frame. This is not resolved by changing the offset; when we tried this, it just duplicated the first frame we threw down. This happens when doing an assemble edit as well.
We temporarily resolved this by setting the insert to begin on black so that a black frame was duplicated, but next week they need to recapture the first and last 2 minutes of the show (90min in length) to add credits, and layback again through an insert edit.
Obviously we can’t be duplicating a frame, as this will cause a frame jerk, and will throw everything else off, including our audio. The clear solution here is to lay back from the start but this would be 90 min to recapture, 90 min to lay back to hdcamsr, instead of just capturing the 2min start and ending, and then frame-accurately re-inserting these.
We’ve spoken to AJA tech support (who are excellent, by the way) and a few others, and they aren’t sure, but apparently this is an issue that may be caused by certain versions of FCP, Quicktime and Kona drivers.
Someone we know said that they had some sort of solution to this in the past, but can’t remember how they resolved this.
Has anyone run into this, or found a solution? Does anyone have any ideas? We should be able to do frame-accurate insert edits with the Kona card in theory, but we really need to figure this one out.
Here is my system info.
Mac Pro octocore, 8GB RAM
XSan 2.0 via Fibre channel
FCP 6.0.3
Mac OSX 10.5.2
Quicktime 7.5 (149)
Kona 3 drivers 5.1 NDD720p23.98 to 1080psf23.98
1080psf23.98 to 1080psf23.98HDCAM-SR

Do you know what deck it is? And HDCAMSR is in every way overkill for the project. Are you mastering for a film layoff? If I were to do this I’d upscale the final locked film to a 10bit uncompressed 1080P timeline via the CPU before attempting the layoff. Are you going from deck to deck via the AJA control panel for up-convert, and trying to make the insert that way? What is your clock source?
