Getting Jagged video when exporting out of AVID Xpress Pro
I am importing video at 720×480 non-square with lower fields first. When I export the video to quicktime using DV compression, 720×480, lower field…I get jagged edges on the export video. When playing in AVID it looks fine. I tried an AVI file as well and still get the jaggys. The video is fine when it is still, the moviement causes the jagged edges. HELP!
Anyone have any ideas? I’m all out!

What version? There was a known bug using DV compression on export creating jaggies in the 5.1-5.2 era of Xpress Pro. Try transcoding to a non DV resolution and try again to see if it is this issue.

Where are you viewing the exports?? On a computer monitor or TV/broadcast monitor?
Computer monitors are Non-Interlaced, TV’s/Broadcast monitors are Interlaced. If you’ve exported it with LowerField First, then you’ve got Interlaced images and if you’re viewing that on a computer screen then you will see the jaggies.
To overcome the jaggies on a computer monitor, export as Non-Interlaced.

I also wanted to add that the reason you’re seeing it “fine” on the Avid screen is because even though that’s a computer monitor, Avid only displays single field. So in short, the image is not being played back as interlaced from Avid.

I have the same problem. When I export video to a QT Ref file, and compress for a DVD, I can see the jagged edges through the whole process — even on my TV while playing the DVD. Looks fine in the avid.
