Video Quality-Workflow Question

Hello,
I have several Vegas (7) files that contain video clips (SD), text, photos & some effects. If I render these to avi (NTSC DV) then import those avi files into another Vegas file then render to mpeg2, how much quality if any will I lose? I ask because in the past I have had trouble with Vegas files rendering (crashes) that contain imported .veg files. If I render to avi then follow the above workflow I have no rendering problems.
Any thoughts are much appreciated.

If your original clips were DV then you'll suffer no loss at all. The photos and titles will lose some, especially around hard contrast colored diagonal & curved edges. The loss is rather small in most cases.

Adding effects will result in some loss as this will cause the video to be recompressed when rendering.

In general though, SONY's DV codec is amazingly good and it's worth using. Give it a try and see.

If you want to minimize loss even further try using the SONY YUV codec as this doesn't compress as much and doesn't affect the color resolution as much as DV does. There's also HUFFYUV which is lossess or you could even render to uncompressed.
