I want to email a 6 minute Video done in vegas 5. Rendering to WMV9 sucks! Too much quality loss and still a large file. Would Divx be a smaller file and maintain the quality??
If so, how can I import the DivX codec into Vegas??
If I am not mistaken, both Divx and WM9 calculate their file sizes based on bit rates. So both formats would be approximately the same size. Personally, I would use WM9 if forced to choose between the two codecs. However, All of my encoding these days is done with Nero's H.264 AVC codecs. Only problem is not everyone has the playback ability unless you have a H.264 AVC capable player installed.
Multiple generations of rendering are never a good idea. Rendering to MPEG and then to WMV will lose much more quality than going straight to WMV to begin with. It would also waste a lot of time.
