to open the final cut .mov dvcpro hd files in Vegas, bring them into the timeline then you have to go to event pan/crop and hit “no” on maintain aspect ratio. For some reason quicktime does not embed the aspect ratio in the file, or vegas can’t read it. Not sure. I usually change the first clip in pan/crop and then copy and paste attributes to all the rest of the clips on the timeline before editing. Probrably an easier way but that is how I do it. I have not gone back to final cut yet.
