Re: Playback issue
 

Are we taking into account the natural judder that occurs with 24p while panning and tilting at certain rates? I played the Vimeo file and the pan in one direction is fine but the opposite direction has a slight judder. Film camera operators learn to avoid certain pan speeds when filming landscape shots without a subject to follow in the frame. I am not insisting that this is the problem but a consideration. Also there might be something screwy with the codec that JVC programmed that confounds some graphic cards.

I went out today to do more test shooting, and later I brought the media to another editor to see if the playback issue was present. I recorded various shots at 30p and 24p in HD, using 50Mbs and 35Mbs. My editor friend imported the media in Adobe Premiere on a high powered system. Playback on the timeline was choppy and rendered videos did not play back smoothly. "I don't know what to tell you" was his comment.

So now I don't have confidence to use the camera on a paying gig next week...I guess I'll have to use the 700...not happy.

It's weird, even 4k on a 4k timeline plays smooth in Edius, what I also don't understand how it can play smooth on my system yet be choppy on multiple systems you have tried it on.

On my 2013 MacPro, taking the HD files from the Google Drive and loaded onto a RAID5 drive, the files play slightly rough in QuickTime but perfectly in FCPX. The one question I have is what was the shutter rate on the footage? More than 1/60?

Re: Playback issue
 

The shutter was 1/60sec. I know about low frame rate shuttering, I can deal with that, the issue I'm seeing is more like frames being dropped and the video "jumps" randomly. I only seem to notice this problem when the shots are panning. Static shots look fine.

I haven't played with 60p or 60i footage, maybe I look at that tomorrow.

Thought I had an issue with the 4GB spanning, just misunderstood the setting.
