Why is it necessary to render an avi file in Vegas 4? I plan to burn to a dvd using dvd Acrchitect? Furthermore, Dvd architect also renders an avi file before burning. Is it necessary to render in both programs? Thank you.
No. Not necessary in Vegas (or DVDA) unless you want the video you edited on the timeline to show up on your DVD :0). What you wind up with on the timeline is not the actual DV file because Vegas is a nondestructive editor. So, to make an AVI (or MPG) file that is exactly like your timeline, you must render the timeline to a new file (AVI, MPG...etc.). Then, you can import that file into DVDA. If the file you make is AVI, DVDA will render it into MPG before burning it onto DVD. If it is MPG (and in the DVDA template), it will not re-render the file.
