Hi all.

I captured 5 minutes of video @ 720 x 480.
I load it into Vegas Video and it plays
perfectly via TV output but, the second I try to add an effect or even just pan the main video track the tv output is really slow and way out of sync. Same result, (maybe a little better) at draft quailty.

Is this because I am using the video card that came with my pc and not a high end video card?

I doubt it's the video card, but you should give more system specs.
How much RAM do you have?
Anything running in the background?

Hi Francis,

This is normal. Depending on the processor-speed of your computer, Vegas will reduce the framerate of the playback, but still show you the composited image. More heavily composited/FXed video will have lower framerates.

You can see the framerate in the lower righthand corner of the preview monitor.

To preview composited images at full framerate, use the "Preview" quality, and pre-render the small segment you are working on using the "Loop-selector tool".

You can also let the small segment loop-play until Vegas automatically builds a temp file that plays at the highest framerate your processor can manage.

did you make build a RAM preview? Select the clip-tools-build dynamic RAM preview.
Maybe that will help in some way...depending of the memory you got under the hood.

System:

Winows XP
512 Ram
P3 925hz
7200 40gig internal HD (C) System
7200 80gig internal HD (D) Video
7200 100gig USB 2.0 HD (E) Audio/GigaStudio drive (80 gigs used :) Im an audio guy)

Firwire Card and Dazzle Hollywood Bridge.
20inch Flat Screen SVHS input TV.

I just tested. All I did was drop a picture into the time line - drew a small cross fade up from black and the pictures plays back on the TV like this.

Bip

out of fade

EDIT:

Here's a thought.

Since this is a digital file could I not resize it to 320 x 240 with Vdub and then do my edits and then render out back to 720 x 480?

Hi Francis,

Rendering to a smaller file and back will kill your resolution, and is unneeded.

Vegas prioritizes the image, then the framerate. This is the way it is supposed to work. Vegas is the only NLE that will let you see your compositing of umlimited layers without rendering first. The trick is reducing the framerate. Again, if you select the range of the fade-up with the loop-selector and pr-erender the segment or let it loop play a few times you should see the segment in full framerate.

If you print to tape or create an avi file it will look fine.
