Re: [Avid-L2] Avid DPX in Resolve Performance Issues?

 

I exported to 10 bit RGB 4096_2160 from Avid.  So I guess that's DCI or sometimes called true 4K.  I've played around with setting timeline the HD etc... but nothing seems to get playback without stutter.

I haven't ever performance tested the system but I do know that with and OWC Elite 2 drive Raid with the camera original which is from a Panasonic Varicam 35 shooting AVC-Intra YUV 10bit Vlog I could playback the timeline with out any color correction but just a source LUT vlog to rec 709 without stutters.

I would think that would be more computationally intensive than a DPX but I've only exported DPX from Avid and never been able to play it back in Avid world other than to spot check.

Am I wrong to think my 2 TitanX expansion chassis should be able to do this?  The audio doesn't stutter so the timeline is rolling along at 23.976 just both the GUI and the DNxIO show stutters.  I can't tell if the stutters I see in the GUI are identical to those on the DNxIO output because it's too choppy.  In color page the audio also stutters which is different because usually I've seen better performance in color page than the edit page.  Perhaps that has changed in updated versions.  Also the choppy playback occasionally goes maybe a second in sync so the timeline is rolling without a hiccup it's just the displays that are not updating.
