Understanding Rendering

I just started using Vegas 9 late May. Currently I'm running 32bit 9e, but will be running 64bit in Win 7 soon. I come from Liquid 6 and a Premiere background. One of the things that I can't figure out is "rendering"on the timeline. I'm sure I'm missing it somewhere. In LE or Premiere, if you have a clip with effects on it you get a red line that it needs to be rendered for full playback. Once it's rendered the line turn green and you get full playback on your monitor. From what I can see, in Vegas you can either get full playback at reduced frame rate, depending on how many effects, etc., or it will reduce the monitor playback quality for full framerate playback. To see a clip in full framerate, full quality do you have to "render" export a separate clip and to view it? It might be in the manual, but I think I have missed it or that's not how Vegas works. Thanks in advance for any help.

You can render any section between your 2 loop markers by pressing Shift-B. This renders it into memory at your current playback screen settings.

You can also do something called a "Selective prerender" which is not limited by the amount of available RAM (an important consideration if you only have 2 GB. of RAM on your computer}.

From the online help menu (search on Prerender):

From the Tools menu, choose Selectively Prerender Video (shortcut is Shift+M) to render temporary preview files for the sections of your project that cannot be rendered in real time. These temporary preview files are used when you play back that section of the project.

When you perform a selective prerender, a separate preview file is created for each section of your project that needs to be prerendered. Sections that contain transitions, effects, and compositing will need to be prerendered; unprocessed DV media files will not.



I should add that this will only stay in memory (be available for a project render) is you do not make any changes whatsoever to the prerendered segment.

Thanks for the info. It's just been one of those things that I didn't quite get and is different enough from other NLE's that I have been using.
