Even after prerendering my project, I can't get it to play smoothly on an external monitor or on the preview window. Some portions of clips "stutter" or "skip" a bit.
-------------------
I don't think anybody is getting clean ohci previews from the timeline. If you only have one clip on the timeline, it plays fine. Trimmer and media pool also are fine.
It's either a bug, or the limits of ohci previews with Windows. FYI, ver. 2 of Vegas does the same thing.
Best bet at this time is to render and use Vidcap to play out to ohci. Or even better is Pinnacle Studio DV because you can scrub or start anywhere you want while outputing to ohci.
Hey S.F., can we get some feedback on this?

Smooth previews from the timeline are absolutely possible- I do it every single day. Set up a new DV project and toss a captured DV clip on the timeline. Enable the external monitor (preview quality= preview) and play the clip- you should have perfect 29.97 (or 25 if Pal) playback. Add another clip, crossfade to two clips, prerender the transition (good is fine). Play again- you should see perfectly smooth playback of the clips + transition.

If you are not seeing this, it is a system config issue, or possibly a Vegas setting issue.

also...Are you guy able to print to tape from the timeline without glitches?

VIA motherboard, by chance?

This is not a system problem, afaik. These are all systems that play out OHCI fine with everything BUT the Vegas Timeline. You must use high motion clips to really catch it. Long zoom out with a pan will show it.
The glitch looks like one frame is played for a few frames every second or two. It's kind of a stalled look. One clip on timeline fine. Add a second clip, bam. Media pool and trimmer both play fine.
Here is a post sayings lots of people are seeing this.

I edit most of my stuff on my graphics card output for higher framerates. I tend to use the ohci preview as more of a framebuffer to check single frames. When I get a faster computer, I hope to change that.

I'm having this probem too, but it is very pronounced in slow motion. Stall or stutter is a good way to describe it, as if frames are missing. It also prints to DV tape, making the pojects I've done so far look very unprofessional and unacceptable for my company.

lynj:

I'd really like to get to the bottom of your unacceptable playback. Could you email the project (.veg file only) to drdropout@sonicfoundry.com and we'll see what we can find. I'll let the kind Dr. know to watch out for it and send it to me.

You're using the 3.0c update, right?

Thanks.

Dennis, did this problem ever get resolved? Jittres are unacceptable to me also if they are printing to tape. John

I've been using an external monitor for editing for a long time. If you reduce the playback quality to preview you should get smooth playback. If not drop down another notch to draft quality. How well your real time playback is depends mostly on how fast your PC is and if or not it is doing other tasks in the backgroud.

Hesitations during playback of the preview DOES NOT translate to the rendered file if you do things correctly. Of couse you remembered to put playback quality to good or higher BEFORE rendering.

Had the same problems...
Managed to overcome most of them by deleting the jittery clip from the timeline and reinserting it..Make sure Quantize to frames is on!

this solved most but not all jitters

ok, lets back up: is anyone NOT able to get a smooth print to tape?

Hi ,
I can get Excellent smooth playback most of the time, but.....

for some reason sometimes i get a small section that jitters
more often if I use SLOW-MO despite resample switched on.
I have however discovered if I render to AVI first and then print to tape it happens more often. If I print to tape direct from the timeline it happens seldom, if I then delete the event and reinsert the clip the jitter is gone.

Subsequently I only "print to tape" from the timeline and reinsert a jittery clip if needed

i was nder the impression that the preview window has no affect on the final render
it is only important when capturing pictures or watching playback-timeline etc
your (render as) settings override everything else
and i render at best quality now
can someone clear this up please
thnx :)

"i was under the impression that the preview window has no affect on the final render

100% true.

I'm very new to vv3, but have quite a bit of time on Avid. I too have "jerky" video when I print to tape. If I render to any other file type, no problem. It seems to "jerk" the worst during velocity effects. I have yet to fully explore other methods to see if it can be worked around.

Try turning on the resample switch on all events that are time-stretched or have a velocity envelope-

Well...I must say, it made quite the improvement! Thanks!! The video was much smoother than the first render... Many thanks!

I have the same problem as BART.

In order to fix the jittery playback from the timeline I finally decided to format my HD enterely and then I installed only WIN XP PRO and VV3.0c. I captured some clips using the VV capture soft (it works now). Then I played the clips from the "trimmer" and from the "media tool" flawlessly. I dragged one clip on the timeline and hit play: STILL THE SAME PROBLEM !!! JITTERY PLAYBACK ALL THE TIME -> 15-16 fps. The problem is exactly the same as it was before formatting the HD (Please look the first post for a detailed description). To be honest, I don't know what happens at all !

I uninstalled VV3.0c and then I installed VV3.0. I played a clip from the timeline and the frame rate is still 15-16 fps. If I play the clip at a double speed (rate=2) I get 25 fps, so the computer is fast enough. But when I play the clip at normal speed I only get 14 or 15 or 16 fps.

Please SonicEMP and other experts, I think that now you have a very detailed description of my problem. Would you mind helping me to detect the problem if possible ??

Thanks!

When printing to tape, try selecting the "Upper Field First" in the video/field order tab. It seems to have solved my jittery video. However, I'm losing sync quite a bit and have yet to find a cure for that... Hope it helps...
