1 Frame Offset Issues
I’ve been having an issue with my setup that even AJA Tech Support can’t help me figure out.
2 out of every 3 layoffs I put out on tape is off by 1 frame. It seems pretty random as well; either 1 frame before the hour mark, or 1 frame after the hour mark. My offset is at the AJA KONA 3 defaults of +1 frame, and I do change that from time to time depending on how the machine feels, but overall I can’t seem to find a configuration that works every time.
Our setup is as follows:
MacPro (2010 Model + 16GB RAM + Fibre Channel HD)
Final Cut 7
Kona 3 + GEN10
Sony 5500 HDCAM-SR DeckWe layoff mostly in 1080psf 23.98. 422 and 444. Everything is setup correctly as far as I know (AJA Confirmed), the sequence settings, the output settings, AJA settings, etc. I tried deleting all preferences from FCP, AJA, etc… no help.
I desperately need an answer – I can say with quite a bit of honesty that this issue is the most frustrating thing I’ve ever worked with. Staying at work for an extra 3 hours every day because a 45 minute layoff didn’t go down right is ruining everything!
Any help is appreciated! Thank you.

It happens with both 444 and 422?
Are you trisync genlocked?
You have tried the tricks such as selecting all in your timeline and rendering what FCP calls an audio mixdown?
Have you tried exporting a self contained, reimporting, then laying that off?

Yes, the most frustrating thing. Machine control in FCP is a terrible unreliable thing. I share your frustrations, here:
Still haven’t found a permanent solution. Without changing settings, I just keep trying until it works. Or, better yet, take my layoff to Avid, where I get frame accurate edits every time.

I have tried all those things. Yes, it happens with both 444 and 422 layoffs. I am genlocked as well. Both AJA and the deck see it.

I second this. In my opinion this is part of you get what you pay for. Luckily most of the layoffs we do here go to a post house to get posted or satellited out, so timecode accuracy isn’t much of an issue anymore.
I haven’t found a fix here either…Kona 3, to D5 and HDSR. Usually 1 frame off…sometimes not…err!

Ok, I’m not feeling so crazy right now. I’ve been experiencing sync issues with our new mac pro and the 8.0 software. In another mac pro I had issues with the 7.51 software (earlier post in this forum) and last week I figured out that if I downgraded to the 7.5 AJA drives, I got back my frame accurate layback results. (Kona 3, Mac Pro 2010, FCP).
It’s been really frustrating trying to get it to work, but it seems to now….sort of. I haven’t contacted AJA yet – we’re in the middle of an office move so when configuring our new systems I’ll probably have to reach out.

Perhaps give VTR Exchange a shot. It’s free.

I have the solution for you, but you may not want to hear it. Use a decklink card. The drivers for deck control actually work acurately. Someone told me this once, while I was working at a post facility, so we bought one to test as we were sick of layoffs that were randomly 1 frame off. And first try it was dead on. We switched 4 fcp stations for decklink cards and haven’t had to worry about 1 frame off layoff problems again. I dont work for blackmagic, just sharing my experience.

What he said. VTR exchange is frame accurate every time. More reliable than FCP…believe it or not.

Started reading this thread and got curious. I opened VTR exchange but I don’t see an edit to tape function.. only capture and grab..

Try “FIle Open”
the output functions are hidden until you use them.gary adcock
