video stutters

[Dario Boronat]

I have found some other behavior which I will detail in a moment. I agree that AJA should be involved in the solution of this issue and I have sent them a DVD illustrating the problem – I should be on the phone with them tomorrow trying to de-bug the system. I will post the outcome of that call here.

Comments to rest of thread:

1- I have found that the stuttering problems is alway terrible the first time I play back a section AFTER rendering. Playing it a second time produces greatly reduced stutter errors, and playing it a third time produces an almost perfect playback (but there is ALWAYS a minor error somewhere). It’s almost as if somewhere the program is indexing files to the timeline playlist. Estremely peculiar

Another symptom I have observed is that when the machine stutters, it literally stutters on the timeline, momentarily freezing TC output and monitor outputs.

2- I have all my media files pointed at that RAID, so there are no files on separate drives that could slow down the system.

3- I have also experienced the field based jittery video that Butch refers to. As with his experience, it only happened when bringing in video via FireWire. If I brought in the video from the same machine via an analogue source, the video was fine. What I found was that I only got the field jittering problem when importing firewire from my old Sony DSR-11. I have replaced that machine with a new HVR-1500 and have had no problems with importing via FireWire, Analog or SDI. I would do a test with a different machine and see if you have the same experience.

Sorry for the delay on this issue… just got back from Holidays.
I will do more testing today and post details soon.
Cheers

Helping others gives you good cowma.

Were there any resolutions or info that came from this thread??

I’m having similar problems that I need to resolve (lots of problems wth a current project). Hope to do some testing next week, and it would be great to have info on any issues regarding renders/previews and the mix of different formats.
