Dealing with 720×486 material in a 720×480 project
I am trying to put some material in my DV project that was originated on a Cinewave system. The video is 720×486 – 40:27 aspect ratio.
When I put the video into the DV project and render it out to MPEG, it gets weird interlacing/morreit errors, because it is trying to squeeze the extra 6 lines in.
I’ve dealt with the same problem on Final Cut when moving this kind of material to a DV timeline. In that instance, FCP scales it down to 98.7 percent, but it is remedied fully by scaling to 100% and moving it to a position of 1 on the Y-axis.
In Vegas, I’ve tried mixing and matching different combinations of switches and Event Pan/Crop settings, but I don’t seem to have it.
Anyone know the sure solution?

Hmmm…
Not sure, but you could give a try:
Set track motion to default.
Use event pan/crop:
Maintain aspect ratio: NO
Stretch to fill: YES
Width: 720
Height: 480 (sure- you loose the extra 6 lines)If you still have interlace problem (flickery motion) increase or decrease y-center by 1 – so upper/lower fields get into their places.
Some time ago I succesfully used similar technic to convert upper field first footage to lower field first to match the standard DV-avi field order.
Hope that this helps.

If you are editing 720×486 you must crop 2 lines off the top and 4 lines off the bottom before you create your mpeg2 at 480. If you can’t crop in vegas then output an uncompressed file at 486 and drop it into mainconcepts or another mpeg encoder and crop out the 2 lines on top and 4 lines on the bottom.
