F35: URGENT, Odyssey7Q and F35 Issues, please help!

Hi Guys,

We have a bit of a dilemma here. We're down at, quite literally, the end of the end world, the far side of Tasmania. And the Odyssey7Q we're using with the F35 is not playing ball... or the F35 is not playing ball with the Odyssey7Q... either way, nothing is working.

In my tests and camera prep with the camera and recorder we had some slight issues, but now nothing is working. 12-bit 4:4:4 ProRes at 25p is constantly showing interlacing artifacts on either the top or bottom half of the screen (changing cables, rebooting, switching settings etc. - nothing seems to fix it). We tried moving to 10-bit 4:2:2 ProRes HQ over a single SDI, but that didn't work either, our footage all recorded looking blue.

On top of this, nothing we do, and nothing our soundie has tried will get an audio signal into the Odyssey7Q. Neither of the XLR inputs on the IF box will send a signal down the dual-link SDI to the Odyssey, and even plugging directly into the Odyssey's 3.5mm AUDIO IN port yields nothing. The Odyssey's audio input option is permanently blanked out on SDI Only, so we can't change the input to any alternatives.

We also can't find any way to jam sync either the camera or the Odyssey to the soundie's 788 mixer. Only a constant hard wiring will sync them.

So yeah, we have no working picture, and no working sound.

Fortunately I packed the PIX240 in the car as a backup, and that's been fine with the 10-bit 4:2:2 signal and timecode sync. But we've put down a reasonable chunk of cash to hire the Odyssey7Q in order to get 12-bit 4:4:4 and 50fps (and the much better monitor), and it's really hurting us not being able to get it working.

Has anyone encountered similar issues and had any luck resolving them?

Any help would be hugely appreciated. We're a long way from home and tech support down here.

Cheers,

Mark
 
Did you confirm the firmware is the latest version recently released?
If it's already the latest, 2015.8 firmware may change your situation.

I had a kind of synch issue with 2015.9 to 2015.12 versions while 2015.8 and the latest versions were no problem.
I heard some random problem regarding synch so you may have a chance.

Good luck!
 
This happens to me a lot. You need 2 same length high quality hd sdi cables and also make sure a and b go to a and b. If you make it b to a it does that. Ive made that mistake so many times!
 
Double check artifacts are in recording, sometimes they only show up on screen but record properly. Reset sdi a fixes interlacing for me. Worst case, just record 10bit from monitor out port.
 
Thanks Mitch,

I lodged a support ticket last night. Haven't heard anything back yet.
We've tried firmware 2015.8 and got sound but no 4:4:4 ProRes, then we tried 2015.11 and got 4:4:4 again, but no sound. Picture was fine for our first couple of shots, but then started crapping out again, so we had to move back to the PIX again.

Any help would be much appreciated, the 7Q is much easier for my AC to get sharps with.

Cheers,

Mark

I can't help re: the other issues but I do know that neither the camera nor the O7Q/+ can jam sync which is really unfortunately. I think you need a TC box of some sort to keep a constant LTC connection to the 7Q for doing proper TC with it.

Or jam your 788t to the TOD coming out of the O7Q (but unfortunately not the other way around)
 
For a wireless audio sync, could you take the 788 LTC out, transmit it over a wireless audio transmitter back to the camera, and record the LTC to one of the audio tracks? I think there's software that can decode that later.
 
Thanks guys, we just had to abandon the Odyssey in the end. It was just too unreliable and we were losing too much time. The PIX has been a trooper fortunately, and covered us for video, audio and timecode.

Just a shame we couldn't unleash the full quality of the sensor.
