Rendering / Motion Blur problem
on Jun 8, 2006 at 2:55:25 am

Ok so ive got a video for school but the motion blur is really dodgy, it has huge lines and a big ugly motion trail that follows it

here is an example of what it looks like.







(just upped give a bit to verify)

this is merely a fraction of what it looks like at full quality on dvd its hard to watch its so bad...

The original =

Prog -> Vegas Video
Render -> NTSC AVI
Converted straight to DVD

Help please!

It looks like a field order problem. NTSC video is field-based at 60 fields per second. The odd and even fields combine to create a full video frame at 29.97 fps. If you capture with the wrong field order, it plays back the wrong field first, which is really obvious with any horizontal motion. DVDs retain the same field order format, so they're directly compatible with your standard television. So somewhere along the line your field order has been switched. You could deinterlace your video before export, which you would want to do, only if you're creating a video for playback on a computer or on the internet. That's because your computer is a progressive scan display. All lines are played on each frame. NTSC television is interlaced with the odd and even lines played back in separate field scans.
