Is this right

Using Vegas 5.
Win XP Corp
3 gig AMD CPu
1.5 gig of ram
60 gig Windows drive.
120 gig video drive

I have a 1 hour project of 12 tracks consisting of main video track and a few sound tracks. I have voice overs and quite a few transitions and video fx's, some pan and crops and zooms.
My problem is that my playback has degraded and my picture quality is now not smooth when viewed on the tv.

If I render to a new track and then use this avi in a new empty project it plays back fine and the picture quality is great.
Is this normal for Vegas to start to slow up the more you keep adding to a project. I have tried all the settings on the playback rate but they don't make any difference.

I have defragged all the drives deleted all the temp files and even rebuilt all the audio peaks but its still the same. But like I said if I render a section of it and play it back its fine... Just curious because I have not seen this before.

anybody else seen this.

Flack...

The more processes you apply to the video, the more it will slow down the playback rate, and depending on the resolution you've chosen, you'll see a greater or lesser impact. If you use Draft/Full or Draft/Auto, you'll see more frames than if you've chosen Best/Full or Best/Auto.
Generally, Preview/Full is desirable for external monitoring, and Preview/Auto is desirable for computer screen monitoring.

I have tried changing to those settings but it did not appear to make a difference to the playback, I did start thr project on my laptop and did not notice any problems with playback.
I only noticed it when I started to edit on my desktop which is a lot more powerfull than my laptop.
Thanks for the reply its not a problem as such, because the final output is great. I was just curious

It seems to me that Spot was right, but maybe not clear enough?

There's a difference in playing back a rendered piece of video (which is only 1 .avi-file) and playing back what you are editing, which is previewing. With a lot of tracks, effects etc. your pc has to work harder to keep showing everything without glitches. So, when editing it should make a difference in choosing 'draft' or 'preview' in your preview window. Once it's rendered you can use best again (or good) without any problems.

good luck,
Mark

I should have been more detailed, no doubt.
One religion I ascribe to is RAM rendering. Select areas that you need to see in full motion, full rez, and hit CTRL+B. this will render that section to RAM, allowing you to see full frame, full motion. Much better than pre-renders, and leaves no detritus on your hard drive. Also allows you to move thru the project faster, IMO.
But...as you add effects, add filters, change speeds, add composites, your project will always lose framerate and/or resolution. At least you can control this in Vegas.

When you hit CTRL+B and render to RAM, do you change the preview setting to BEST FULL or does rendering to ram automatically render to best full?

I've always been curious about this.

It appears to render to whatever your preview settings are. If you do a RAM prerender and then change the preview settings the prerender is lost.
