prerender

i have a project that takes to long to render in one session. i thought that by prerendering a section at a time then i could piece the whole render process up into managable pieces.

when i cut the end off of my project by selecting a loop region then my prerendered files dissappear from the timeline.

any idea how i can selectively render my project?

thanks in advance.

Try the "Render to New Track" option instead.

A note about how Vegas selectively prerenders.

Vegas prerenders areas on the timeline, not the events. So, if you prerender minute 2 to 3 of the timeline then that is exactly and literally what is rendered. If you change anything in that area you break the prerender, even if all you do is move something. You can have absolutley no change in the events or how they relate to each other, yet if you move them a frame then the prerender is null and void.

I'm not saying it's right, or good, or desireable. It's just the way it is.

the important part of my question remains...

is there a method of rendering a project in parts? as opposed to 'all at once'

thanks in advance.

Sure.

Just render selections to a new track. The only problem is that this always creates a new track but if you name the first track to something like "Renders" then you can drag all subsequent renders to that track and then get rid of the surplus tracks. (Okay, you don't have to name it anything but it's probably a good habit)

As long as these are on the top track and in your final format (or maybe uncompressed if you can stand it) then that last render should be pretty fast since it'll largely consist of copying instead of rendering.

This all takes some concious effort of course. It would be nice if Vegas treated selective prerenders as if they were on a track of their own and would ripple edit. You don't even have to see the track, Vegas just needs to behave as if it existed.

Also, you could work on individual sections of your project, rendering each section to its own Video for Windows (avi), and then assemble the avi’s in a ‘total project’. This workflow would allow you to continue to work on one section while another section renders by running multiple instances of Vegas.

BTW, prerenders (and Ram renders) are generally used as an editing tool to ‘preview’ short sections of video that have fx, transition, etc., so the preview will playback at full quality and full frame rate.

Yes, just save a copy of your project and then open it in a second instance of Vegas. Render away while you work on the original.

Maybe before you save a copy of you project, mark some regions to render. That way later on you'll know exactly where the new render goes.
