Simplest thing to do is to open up Vegas as many times as you have projects to render, load each project into a Vegas instance, and start them all rendering. If you have Windows 2000 or XP i would suggest setting each one's priority to "Below Normal" after you start rendering and before moving on to the next one. It's also helpful to set the Dynamic RAM preview to 0MB. They'll all run together all night. It won't be any faster than doing them individually, but once you've spent a few minutes getting them all running you can walk away and forget them until morning.
There is also a batch rendering script available. Try checking at vasst.com or search in this forum for "batch rendering script".
I have lots of free batch scripts, each doing a different kind of batching.
Let see ...
BatchRenderGUI - Lets you render the current project (or just the current selection) to multiple templates (e.g., to MPEG-2 and AC-3). Has a GUI interface for selecting templates, hence the name. Also lets you render each region in a project, each to separate files, using multiple templates.
BatchConverter - Renders all media files in a directory. If you have a bunch of AVI files in a folder/directory that you want to convert to MPEG, you can use this. Don't even have to bring the files into Vegas and put them on the timeline.
Batch_Project_RenderQueue - This one takes all the VEG files in a folder and renders each one, in its entirety, using a single media template.
I probably have some others lying around, but that gives you and idea.
I'll add my vote to that, hardly expensive and very capable the Multirenderer be. It'll render regions as well as whole projects and to multiple outputs, all in one batch, batch can be saved and results logged.
An "instance" of Vegas is the actual "occurrence" session of Vegas you have present at the moment, OPEN. So, another instance of Vegas would be another OPEN session of Vegas. This is one of the BOONS of this gorgeous software, the ability to have more than one "session" = "INSTANCE" of Vegas open at one time. Often I can up to 4, yes 4 instances of Vegas open at any one time.
This is useful if you don;t want to "mess" with some work you already HAVE open but just want a kinda of SCRIBBLE pad to "work-up" some ideas - yeah? Often for me doing this away from say 10 tracks which have say some track motion, some Fxs on a track and some audio being configured, is brilliant.
.. oh yes , then you could ALSO nest un-rendered Vegas Projects within open and OTHER Vegas projects too!!! Now THAT has to be seen to be believed!
Tara: go to Start / Programs / SONY / Vegas 6.0, click on the Vegas 6 icon (or 5 or 4 or 3, depending on what you have). This launches Vegas in a new window. That's one instance. Do this again and you launch Vegas again in another new window, and you now have two instances running in two separate windows. Repeat as often as you need.
To set priority in Windows 2000 or Windows XP, Ctrl-Alt-Del and bring up the task manager. Select the Processes tab. Right-mouse-button click on the program you want to change. A menu pops up with various priorities listed. Most programs are set to Normal. Setting a program to Below normal will make it more "polite", in that it will let other programs go first. Since most everything running on your computer besides Vegas rendering is pretty much completely idle time, changing Vegas to a lower priority won't slow it down much. With the lower priority though other programs will respond quicker when you do ask them to do something. If you have 3 or 4 Vegas renders going on all at once at normal priority you'll quickly get to the point where the system takes a very long time to respond to your mouse clicks or keyboard presses.
Multiple instances doesn't seem clunky to me at all, especially when i have 9 renders to do by morning and almost every one uses a different template to a different file type. I start one up, forget it, start the next, forget it, etc. then have a nice peaceful sleep. The only difference between that and rendering one at a time is that i get to sleep the whole night instead of getting up every hour to start the next one.
I suppose if you have a large number of renders that are going to be all the same template and file type, then a batch script is very helpful. That's rarely the case for me. Almost every render i do has something unique, whether it be adjusting the bitrate, rendering to a different resolution, adding ID tags specific to that project, or many other possibilities.
I know this thread is 2 months old, but I have to say thank you to Chienworks. I too have a need to do bunch of renders from different veg files with different templates etc. I knew I could run multiple instances (I've had a render going while editing in another instance), but I was afraid that somehow multiple renders would "clash" with eachother. So I did a search for "multiple renders", the first hit was this thread, with the answer! I will sleep better tonight. Thanks!

How about open the main project, put the other projects on to the time line and then put regions on them and then use the Batch render scripts and select the region option.
