Multiple Rendering Question

Because there is a limit as to how many video tracks you can have if I need to include more is the only way to do this is render the video and then import the rendered version and then keep adding on top of it?

I did this before and for some reason when i rendered the second time it took 4 times as long as the 1st one did even though I only had 2 tracks that were rendering the 2nd time and 4 the first time.

Im sure your probably wondering why I would want to add so much so heres an example.



What I would like to do is have a show where I can have like a round table discussion with multiple people.. so instead of 2 video feeds I would need to have like 4.

You can have 4 video tracks in Movie Studio. Right-click to the left of the timeline and select "add video track."

I know but I need more

If I have 4 Videos I still need a track for the background - text scrolling and so on

Perfectly right.

That is one of the reasons why I changed to "the full" Vegas Pro, which as "enough" tracks :-)

Probably you know this Vegas comparison http://www.sonycreativesoftware.com/vegaspro/compare

I would love too but im actually really new to all this editing and stuff..I probably wouldnt know what half those features do and then you have the big price jump which is my biggest hurdle. Ill put it on my Santa wish list

So .. what file type / format did you render to?

WMV

I have a quad core with 4 GB Ram and I turned everything off to make sure all processing power was directed to the project

Well, I'm no expert .. so I waited for someone more knowledgeable than me to answer .. but I guess not ;-)

Don't render to WMV. Render to somthing like uncompressed AVI. You want your "sub" render file to match as closely as possible to your "raw" files (from the camcorder)

If you render to WMV, add it to the timeline and re-render then Vegas has to do a *lot* more work .. hense the long render times.

If you're final end product is WMV .. fine, but don't render anything in WMV for intermediate use .. only for your final render.

One other thought on why later renders might take more time; sorry if you already know this...

The longer renders would make sense if your later renders were for the text overlays or other generated media, or where you may have done some pan/crop, etc. In those cases Vegas has to do lots of math (meaning extra CPU cycles) for pretty much every frame, thus it would take a lot longer than just rendering out "plain" video.

The other comment was correct, as well... switching between formats can cause longer renders as well.
