Dynamic Ram Preview

I notice under preferance that there is a setting for Dynamic Ram Preview. I'm not even certain what this is or does. I have 512MB RAM & a Pentium 4 2GB processor. Should I be increasing this Dynamic Ram Preview figure on my machine for even better performance & it so what would you recomend? It says that maximum is 382MB.

This is only used if you build a dynmic ram preview (rendered in RAM only). The more RAM you allocate, the longer preview you can have. Basicly, it renders a certain section (the blue selected area) to RAM, and you have your video played back almost perfectly (i say almost because if I say perfectly, someone will say otherwise. :) )

I can playback a section of video that has generated media, various plugin SFX, and multiple sounds at 30fps when previewed to ram (highest quality) but only about 10fps when played normaly in my preview window. Very useful to see how something is going to look w/o wasting disk space.

Hi,

Like the friar say, RAM is good (and fast) for ram-rendering previews. It is also good for working with stills.

You might notice that even if you don't "RAM-render" segments, Vegas will progressively recompress and cache a segment that is permitted to loop repeatedly... I found Vegas will cache and play more footage than it would use for a RAM-render.

While fast, RAM renders go away... if you want to keep the rendered-preview, you might want to pre-render which saves a temporary file on disk.
