720P lay-off problems

[Gary Adcock]

[Tom Bristow] “When attempting to lay off to the 720P D5 tape the picture constantly jumps or shifts, what looks like incorrect reference (although all the reference to the MAC & deck are correct) and audio breaks up. “

Tom
this does not sound like a Kona Issue, but without info on the driver versions I cannot be sure.

Have you checked
Kona Control Panel is set to 720p
the Files are rendered prior to layoff
the audio files are mixed down
( and just check the trilevel sync to make sure that the Kona sees it.)

check the Kona control panel under CONTROL, and make sure it is in EXT REF, and not Video In. I have seen this hi error rates dumping out to a Digi Beta from the Kona 2 downconverted – it was a reference issue.

Bob –
Thanks for the reply – when you mention the EXT REF is that the “ref in” tab. Under CONTROL in the GENLOCK section the choices are “freerun” “ref in” and “video in

[Tom Bristow]

Thanks for the reply – we made sure that all of our Video and Audio settings on the Kona card were set to 720p59.94
The files in these cases are completely rendered as an uncompressed QT. I need to look in to the audio mix down

yea – ref in – i am not in front of a system.

Actually, I would change the Kona Ref to Free Run. Also make sure that no sync is connected to the D5. The issue may be that your sync is just a little off. The Kona cards are hyper-sensitive to imperfect sync.

“Free Run” did the trick !! (it is always the simple stuff) I changed the CONTROL -> GENLOCK -> to “freerun” and the material lay-ed off flawlessly. this worked with the Kona routed to the deck, and the deck routed to the Kona (a loop). to be sure we switched back to the “ref-in” and the problem re-appeared.

CONTROL -> GENLOCK -> FREERUN produced a clean 720p output. thank you everyone for the help
