when rendering to the vtfs from an animation program, you can render out as any file type you like that is supported by the vtfs, as long as you pre-stripe a segment of your drive first. you have to have enough room for the contiguous video file.
to pre-stripe a portion of your media (vtfs) drive, right click on the desktop with the mouse, or on windows explorer. select new ] dps media file from the menu that appears. a window opens:

enter a name for the file you want to create, enter a data rate and a duration, and the file is created. if you play it back in dpsvelocity, it appears as a black clip.
