HD to SD via Kona to Digibeta, timecode issues!
For a cable show shot at DVCPROHD720p, we are preparing NTSC 4:3 Digibeta deliverables.
I just got the shiny Digibeta rental deck and Kona LH card today, connected via SDI, and while I can send video signals to the deck, trying to “Edit to Tape” to a pre-blacked tape results in the edit missing it’s mark by 1.5-2.5 seconds every time.
Generally speaking, if I for example set my in-point at 00:58:30:00 in my timeline, and 00:58:30:00 in my Edit to Tape window, it’s going to start writing video on the tape somewhere around 00:58:32:02 or so, but not exactly.
I have no idea why it misses consistently. The rental techs set the system up but were a bit dismissive of these obvious problems during setup (they’re AVID guys first and foremost and wrote it off as “a final cut thing”). I know the obvious thing would be to demand they return to fix their setup, but it would be nice to just know if anyone has had a similar problem and knows the solution here.
The sequence is DVCPRO HD 720p 29.97 (which doesn’t appear to be an option in the Kona LH settings under Sequence Preset). My A/V settings look like this:

what model digibeta deck is this?

Is this an easy setup? What does your AJA Control Panel setup? Do you have a different setup for output to tape?

Andrew,
I have an LH and a Beta deck, and on occasion it does this, trashing prefs has always fixed it for me.
Have a wonderful day.

It is a Sony DVW-M2000 deck.

https://img.photobucket.com/albums/v236/archibaldcrane/Picture3.pngThese are my Kona Card settings. We’ve tried both NTSC and 720p60 easy setups to no avail. It seems that not only is it offsetting the timecode, it is also not doing the center-extraction crop from the HD source – it’s giving me a letterboxed display even though I select “crop” for the downconvert.
No idea what is going on…

OK
the Trash your prefs.2) the inbound single should be HD not SD into the deck- part of your issue is that the HD format needs to be the Primary video and the down convert needs to be the secondary settings. – according to the CP your set up is not correct,
quit everything that is open – trash both the FCP and AJA prefs then reboot and reset your project.
