Frame Accuracy (or lack of it) on edit to tape in FCP
Hi there,
Having a recurring and intermitant problem with Edit to Tape in FCP 5 across 5 different G5 systems and a selection of decklink cards. Our digital cuts are (around half the time) a frame late when editing to our DVW A500P. All our systems and the deck are genlocked to the same source and all are running on the latest BM drivers with FCP 5.0.4.
This is a frustrating problem that is costing us a lot of time in re-starts and deck time. I understand that this is also a problem that has been encountered before, however, I can’t find any posts concerning a possible fix. I really need to know if this is a problem with FCP, Decklink or our video setup.
Thanks in advance for any help
Cheers
Mark

Can’t say but we occasionally get this too. Sometimes it goes away for a long time and then it’s back. Another funny thing.. sometime the audio is out of sync by one or two frames. We can tell because the beep and “2” are not lined up.. this mastering to a Digibeta via SDI? How can the sound go out of sync? a mystery. Costs a lot of time.

Hi Mark,
Please try the v5.6.2 driver as that is the last non-universal binary driver for use with Final Cut Pro 5.04.

You might need to calibrate the timecode offset (in FCP, Device Control Preset tab).
In this case, ensure capturing a clip with (reliably*) burnt-in timecode. Open the clip in the viewer, note the offset between the clip’s tc and the burnt-in tc and set the appropriate offset in the Device Control Preset window. Save the preset, and remember that this offset is only valid for this computer/this deck.
*you may record a test with the superimpose out on the DVW A500P, and reconnect to the normal out when done.
Hope this helps.

I’ve had this similar madening problem too – fiddling with the Device Control Pre-set (altering frame delay in playback) & also always using Edit to tape rather than Master seem to be the work-arounds. I’m using 8 Bit to Digitbeta & Declink HD btw.

Hi Jezza,
Thanks for your reply. Specifically what setting re: frame delay have you used? I’d be very grateful if you could let me know
Cheers

PS. I am pursuing some of the other soloutions suggested in this thread and will try and let you all know what worked when I figure it out.

I think you’ll find the 5.6.2 drivers will solve the problem. It did for us.
