If you are capturing and printing to/from a MiniDV camera:

Capture to NTSC-DV or PAL-DV
Render to NTSC-DV or PAL-DV

In general, the more the files are compressed, the longer it will take to read from them or write to them. DV is less compressed than MPEG so it can be read and written faster. Uncompressed theoretically should be fastest of all, but unfortunately all the extra bytes that must be handled offsets this advantage. DV seems to be right at the peak of speed. Vegas is also written to work natively with DV so it is optimized for this format.

Codecs like DivX and MPEG have two types of compression. DV is compressed spatially in that each frame is taken as a unit and squeezed. DivX and MPEG do this, but also add temporal compression which is using groups of frames and finding common elements in a string of them that can be eliminated. This saves lots of space, but drastically increases the time it takes to decode or encode these formats.

Now, having read your other posts, it seems to me that your primary concern is to work with source material from DVDs and reencode them to other media, perhaps with minimal if any editing. One thing you should understand is that Vegas is intended to be a very versatile, powerful, easy, and high quality editing environment. As such, it is optimized for quality and ease of use but not for speed. If your primary goal is to move compressed video files from one format to another then Vegas probably isn't the right tool for you. There are probably plenty of other software packages out there created specifically for that purpose and perform them much faster and more efficiently than Vegas does. For example, the DVD2AVI ripper will take a .vob file from a DVD and convert it to a .avi file on your drive very quickly, but it doesn't allow any editing at all.

Also keep in mind that if these DVDs aren't your own productions then you may be violating copyright laws by using material from them.

ok Chienworks. you almost have it there DVD2AVI doesn't produce an AVI. Or does it??? because If I could at least work witht the AVI then that would be perfect.
