we’ve done some testing since, and were surprised in small tests, that playback off the FW800 instead of the Medea RT3X showed NO glitches.

Another curiosity: When the media is on the Medea, and exporting a quicktime from the timeline to the Medea, write speeds are brutally slow. Read from Medea, write to internal or firewire, it’s fast.

Still not conclusive but promising – thanks for the advice, will post again when i think we know something.

We usually output NTSC unlike the original poster who is working in PAL. However we do our own conversions and outputs to PAL also.

No we haven’t tried playing back from Firewire800, but it’s hard to believe a RAID0 Medea R3TX with firmware updates and Atto UL4D with current drivers can be too slow?

Kona is in slot 3, UL4D in slot 4 as recommended.

G5 has passed hardware test. No cellphones involved AFAIK.

this problem does NOT go away whether material is rendered or not, whether the timeline is exported to single clip, etc. We have NOT found a workaround for this problem. Our solution is to re-insert into the dBeta if we catch the glitches by eye on layback or playback. This is not as easy as it sounds because obviously the timecode on the 29.97 tape does not match the timecode in the 23.98fps timeline. And nor can it. If you haven’t worked with 24fps material this may all be rather baffling.

We’ve had the same problem in varying degrees with SD 8 bit (all codecs — aja, apple, blackmagic) and nearly the identical config – DP 2.7 4G or 8G in both panther and tiger. Medea RT3Xs and CI arrays of cheetahs. Whether i install the system fresh or upgrade. Exactly the type of hits you describe. So far aja has been unable to provide a working config.

This is a HUGE headache – we’re going from one bad system to another it seems – trying to upgrade from G4s with cinewave, whose 24 fps video clips output to 29.97 tape with 3:2 started stuttering after the upgrade to Panther.

So for standard definition 24fps material going to NTSC tape the last good config we had was FCP4.0.2, Cinewave 4.0.2, on a G4 running OS 10.2.8

Not just sad – maddening.
