pan and scroll very jerky during playback with Kona

[Tom Daigon]

I have an HP Z820 with a GTX 570 card and the Kona 3 and get smooth playback from DNxHD media.

Lets talk about the studio rig since I am now on a PC and have more experience with that platform these days.

1.What is your video card. Do you have the latest drivers for your it?

2.Are you running CS 6.03 and do you have the latest 2 (AJA and Adobe) drivers?

1-I’m using a Quadro 4000. Yes i have the latest driver

2-Yes running CS6.0.3 with the latest AJA and Adobe driver

Maybe what is acceptable for most people is still considered ”not good enough” for me as i do mostly online so it’s very important that what i see is what i get, unfortunately, it’s definitely not the case with Adobe and 3rd party capture card such as AJA and BM.

The same playback is rock solid in Media Composer and what i see on the reference monitor is exactly what’s on my source file or what i would see as final print.

As a editor at 2 professional facilities over the last 30 years my expectation of performance maybe a little more stringent then yours 😀

That being said, on my system there are 0 frames of delay on the external monitor. And all clips play back at speed with no hint of stuttering or any frames dropped.

It would seem there is something amiss with your system.

What kind of raid are you playing your media back from?

It’s probably b/c you’re editing on a laptop.

what setting do you have in video preview under sequence setting if you were to playback 1080psf @ 23.976 DnxHD ??

I have a ProAvio / LSI sas Raid (800Mb/s), Flanders 2461 and Panny Pro 50” pannel, 0 frame delay on external monitor. As i said playback is tight and ”what i see is what i get” on all system (Mac and PC) with AJA via Avid, Autodesk Smoke and even FCPX with the exception of Premiere CS6.

I just freelance at a studio with Avid and CS6. All running on Z820 and AJA. PP Playpack on all their system is just as flaky as mine!

[Anhtu Vu] “I tried different playback settings in PP, they all yield the same result…for example, this particular file is in 1080psf @23.976, codec is DnxHD, i have the playback set at, 1080p23.98 custom with DnxHD codec. playback is still stuttery”

Anhtu,

Have you tried to re-encode the video into something else (e.g. H.264), and see if it still stutters?

Anhtu it depends. For many projects I just use the MPEG I frame option since they render very fast.

If I want to use the rendered preview files when exporting or QC is important during the edit, I use DNxHD.
