control prerender segment size?

What controls the prerender segment size? Usually it generates 9-10 second avi files but sometimes, for no apparent reason, it will generate a much longer file. I'm looking at a timeline now with a bunch of the short ones and then one five minutes long. I have to make a tiny edit in the long segment that will now take hours to re-prerender.

Hi Jason,

If you are using V4, you might try:
Saving the project as...
Rendering the whole program to a new file
Place the rendered file on a top track exactly above the original, then splitting it and opening gaps where you need to edit any specific sections.

V4 should use the prerenders to make the render the new file... no lost time and no lost quality.

Good point. That sounds like a better way to go when prerenders are important. I'm still curious about that segment size, though.

The STANDARD Prerender segment is exactly 10 seconds unless the whole area to be prerendered is less than 10 seconds.

There was a glitch in VV 3 which allowed the program to miscalculate and sometimes instead of, say, 270 segements at 10 seconds, it calculated, say, 49 segments, and made them each VERY long. Until a few days ago, I had not noticed this happening in Vegas 4.0. But, the numbers I just quoted are the numbers that V4 gave when it miscalculated Friday. Again (for SoFo) this was the FIRST time I noticed this in V4.

I didn't notice until hours later, and then it was too late. When I was still using VV3 I got into the habit and would look at the bottom-left of the screen and if the number of segments appeared very wrong, I would cancel the prerender and start it again. I guess I will have to get back into the habit of watching that indicator, again. It can really mess you up if it miscalculates.

Sometimes, when it miscalculates, VV 3 would lose track of the enormous segments almost immediately. Sometimes, as you mentioned, you would lose several minutes by making a change which SHOULD have only affected 10 seconds, or at most, an entire clip. Either way, it was a pain.

I hope that V4 isn't as bad at this as VV3.
