Playback jitter FREAKOUT
I didn’t used to be like this…
I’m making a video and editing footage. While I play the shot to find my in and out points in the left monitor, all is rolling slick. The second I make my cut and insert it into the timeline, when I hit playback the image starts to jitter (in right monitor), skipping frames randomly. It becomes really ridiculous in terms of trying to see if the shots flow since frames are skipped all the time (not the audio though). And that happened since the first cut, meaning that it’s not because the computer is searching through tons of shots.
And on top of that, accessing different sequences from one tab to the other in the timeline takes forever, the program has slowed down alot. Feels like I got a prehistoric pc… ( I have a pentium 4, 2G, 1GB of ram, matrox millenium g550 by the way)
-Is it because my footage is 24p normal coming from the panasonic camera? I wouldn’t be that sure since I previously done some other work with 24p normal and didn’t have that jitter at all.
-I tried different options in the project settings, but it didn’t change anything.
-Image quality is even set at DRAFT.
-I have no other big program running at the same time.
-I thought that updating to the new dirext X 9.0c today could maybe help, but it didn’t. I might have had it already, I’m not sure…
-At this present time there are no effects at all, this is just a straight cut montage.
So, any idea why it can’t play properly in the right monitor?
Thanks for your time!

How much disk space left? Is it 7200rpm or 5400rpm? How do you set your preferences?

Hi,
Got 3gb left on my C drive, 9 on my E drive (which is the one holding the video files).
-All drives are 7200 rpm.
-Scratch disks: Video and audio previews + conformed audio are run from my G drive where there’s 14gb of free space. (plus all my drives have been defragmented before I started the project).
-And in General, the option “play work area after rendering previews” is checked. I’m not sure what this actually means…
Does all of this adds up in resolving my mystery?! Thanks!

Pat,
All I can think of is the disk spaces left are somewhat limited (all 3 drives are relatively small). Well, with 14G for the preview drive and conform audio, it may be enough? Try to seperate the conform audio files from the video preview files drive. Otherwise, I run out of idea now.Perry

thanks alot for your time, I’ll try that out.
it’s hard though, when you got tons of stuff that needs to be there. I’m running 2 projects at the same time… Argh!

ps: anyone else got a clue, feel free to speculate!

Just a speculation…
in playback setting if you checked (may be by mistake)”playback on DV camcorder” you get jumpy playback on the right monitor.

Playback of clips in the clip window uses a different rendering system (Windows) to that in the program window (Premiere), which is why some people report good clip replay and problem timeline replay when they have CODEC or other issues that are OK in Windows but a problem for Premiere.
Is it possible that you need to render the timeline? Invoking RT replay that challenges the hardware can cause the effects you describe, as can the active DV device issue already mentioned. Is there any chance that your source footage is not exactly matching the project settings?
This might just be relevant, too:

Unfortunately, this is not it, as it is set to play on the desktop…
Thanks anyway!

I’ve read the article which lead me to another and then made me change some dma thing in my atapi controller. Whether that will make it work, I don’t know. I’ve also just updated my video card driver. Will see…
Thank you all again for your support.

IT WORKED! Well there were 5-6 glitches (probably due to fast cuts) but otherwise it played slickly til the end!
So my bet is on the update of the matrox g550 driver. Could be the dma thing, but who knows. Should have done one at a time, but it’s working now.
Thanks! The Creative Cow members have always been great to me, so LONG LIVE to the people of these forums!

I bet it is the DMA thing. You need to enable the ultra DMA support. I thought this is an existing system, but sounds like it is new to Video editing? Well, anyway, congrad.
