Clips playing back badly in preview window
I had just loaded 6 hrs of wedding footage into Vegas, and just started to play some clips that I had placed on the time line. I noticed They were playing back terribly(any thing that “had movement” in the frame was distorted with horizontal lines,) but any thing that was stationary, or still looked OK. Fast panning of the camera would also cause this strange thing to happen.
The first thing I thought of was, that the clips were “corrupted”
But then I placed the “suspect clips” in the trimmer window ,and
they played back smoothly without any problem.
Spent most of the day trying to track down what is causing this.
with out any success, your help is always appreciated !!Blayde @ Cornerstone

Is your Preview Window set to Preview/Auto?
What kind of footage is it (i.e. miniDV, HDV, AVCHD)?
If it’s the latter, are you running at least a quad core? -
The Trimmer and Explorer plays in Vegas are unbuffered playback, and unscaled playback.
When you put a clip on the timeline, Vegas scales the footage for optimal playback speed and relevant display in your preview window. this is why Vegas allows you to play back at full, half, quarter scale of original. This is less of an issue with faster computers, but putting your playback to Best/Full and unchecking the scale feature in the Preview window often makes the issue you’re seeing go away.
when you render, you’ll see the same quality as you see in the unbuffered playbackDouglas Spotted Eagle

Mike & Spot,
Thanks for your timely responses, we certainly need them.
We are editing SD/DV on a Windows based system,w/ Vegas
Pro 8.0c.
System has:INTEL CORE 2 CPU 6600 @2.4GHz,2400Mhz 2 Cores
Total Physical Memory 3.25 GB
We did have Preview Window Set To BEST / AUTO But Now To
BEST/ FULL,We also “unchecked” The scale in preview settings.
But to no avail, the same things are still happening.
Is there any thing else we could be over looking, or should I
reset Vegas back to default???Blayde @ Cornerstone

Blayde, set the preview window to PREVIEW/AUTO and see if that helps.
Also, do you have any FX on these clips? -
Mike,
Yes, “Preview /auto” seems to help, but there is still
one clip that is giving me trouble.To answer your
question about FX on clips: I have added them @ the
Project Media area (color correction ect.)because I
will be doing a multi-cam project, and you have to add
FX at that level, to keep the FX locked to the multi-
cam project.I think that how I did it in other Multi-
cam projects.Any other input is welcomed, thanks.

Blayde,
I have a similar problem with HDV footage I shot. The horizontal lines are horrible on movement and action. I could care less about the preview window but the results are painfully visible when I burn to DVD. The simple solution that worked for me was to just right click on each event that has a problem and check off reduce interlace flicker. It helped for me but still not perfect.
I hope someone else will have a better answer. Thanks.

Mike & Mike,
This morning, after my quite time I had a chance to
really think about this preview delimma.
I now realize that it must have been “self inflicted”
in that 6 days ago I was in the control panel of my
computer, fiddling with my Secondary CRT display settings. And I set the 2nd display to a higher resolution than I usually use.(1024x 768)instead of
(960×600)thus making my preview window from Vegas on my CRT screen mess up the preview playback. Resetting my Secondary monitor back to a slightly lower resolution.on my computer has fixed the problem!!! Life is good…Once again thank you for all your help.

Blayde, I’m glad to hear that you got it resolved.
Your solution never would’ve occured to me as I’ve got a dual monitor setup with an external CRT so my preview window is always quite small.
