Can anyone please tell me how to render a Vegas 10 project in a form that will make it suitable to send as an e-mail attachment to someone who has not got the Vegas program?
Most email systems are limited to 5 or 10MB attachments. That's not much video at all, probably just a few seconds. You'd be better off with something like a dropbox account.
Do you want to produce a high quality file that shows all the resolution and detail, or just a "preview" snippet so they get the gist of what's going on?
Bambino,
you really should do it like Chienworks and musicvid advise.
Even though VMSP 10 gives you the option to "E-mail it" (with render options) in Make Movie > Select destination, this impractical suggestion was not included in the v11 any more.
