PrP performance on Mac vs. PC
I love much of what PrP and AE offer thru the dynamic link. I am concerned that performance on my Mac Pro 3.1 / 24 gigs rams / Areca controlled 8tb raid array / leaves a lot to be desired in terms of just simple playback of 1080 Prores clips (for example). In the source window I I can scan by dragging the little playhead control through through the clip and it plays very smoothly (all frames played). When I try the same process in the record window it jumps about 10 + or – frames as I drag. . Full resolution playback or variations make no difference. This occurs on both the AJA and Adobe sequence configurations. CS 5.5 seems to function better on a PC then a MAC and that could cause me to try Avid for better performance..

I know you’ve mentioned this before, Tom, but I can’t remember; do you have a GPU that is giving you CUDA acceleration? If not, I wonder if that would make the difference?

Hi Jason. I use Kona 3 since some clients still have material on tapes, as well as HD-SDI to a engineering monitor for QC and client viewing. In the Adobe literature Ive read. it says the process of playback involves decoding, which CUDA does not do.That is a function of the CPU if I understand correctly. A moot point due to my Kona workflow.

Jason’s question is relevant in that if you have any effects applied to the timeline clips jogging or scanning the timeline is going to be jerky. If you have a CUDA card with CUDA effects applied it’s going to be much smoother.

That is correct. And iff the Adobe timeline demonstrates the same jerkiness, then the Kona drivers are not to blame.

No effects on the timeline , just clips. I guess my workflow might necessitate checking out Avid since not using the Kona is not an option. Thanks for the info David.

[Tom Daigon] “No effects on the timeline , just clips. I guess my workflow might necessitate checking out Avid since not using the Kona is not an option. Thanks for the info David.”
Like I said in the other post the issue is probably not the Kona drivers if it behaves the same way in Adobe timelines.
One thing to try: In Preference:Viewers switch from the AJA viewer to the Adobe viewer.
Otherwise it’s almost certainly an issue with Prores in PrPro or QT issues. Todd may be able to tell you definitively about this.

I have explored the preference switch between Adobe and AJA with no affect. Actually I was using Prores as one example I experience this same ” skipping” playback issue in the Record Monitor with all clips/formats/codecs.

I just want to be clear on whether this happens with jogging the playhead or playing the timeline. I’ve assumed that it’s only with jogging. If that’s the case, does it also happen when you drag the timeline playhead?

Does it also happen when you drag the timeline playhead when you’re zoomed in?
Your slider resolution in the program panel may be too low.
