Selectively prerender video

Would someone explain to me this like I was in third grade? I want to take a region a render it to see how it will look on an external monitor. Then I saw this and how it says that it would be good for an external monitor.

Anyway, I need a helping hand.

Thanks,

Thomas

Make a selection, then choose CTRL+M. This will create a pre-render, writing a temp file to the hard drive. The pre-render section will have a blue line above it. (depending on your theme settings)
A render to RAM is CTRL+B, but this won't allow you to control the settings for the quality like a HD prerender will.

I know how to do it. I just can't decipher the benefits of it over "Rendering to a new track".

Although when I tried the "prerender", it did not give me the choice of where to save it. I couldn't find it after I prerendered.

I use it whenever I've done anything that causes Vegas to render. When you play the timeline, Vegas will read the prerendered (temp) file and send that out to the external monitor. On my system, previews are always a little slow and very blurry and most of the time that doesn't matter but when it does, I use selective pre-rendering.

Thanks, I think I get it.

I jprerender to a new track all the time, as a normal matter of course.

Whenever I take a break, I select the most intense parts of what I've been working on, and PreRender it into a folder I have called, "Prerenders".

Generally, by the time I've gotten ready to resume cutting, the section is done. I drag the prerendered video clip down to the top track, and erase the track it was created on. This gives me a "timeline" representaion of how many effect sections are completed (I do a lot of layering and effects).

If I need to revise sections in the preRender, I cut out the bad parts and insert the changes, butnly preRenderi the revised part.

When the prerendders get too choppy, prerender them again, into larger pieces and erase the older prerenders. This way, my videos always play at speec, PLUS, when it comes time to layouff the finished project to tape, the final render is quick (all the efects are done!)
