I'm getting some wierd interlacing artifacts (I think)in my recent project, which I haven't seen in any prior project. These are showing up in motion scenes and an occasional still which has had a pan/crop applied.
SYSTEM: V4b(Build174), P3-600, Win98SE, 384 MB ram
FINAL DESTINATION:SVCD-NTSC, Video Rendering quality=best, CBR=2375, write sequence display extension=checked, DC coefficient=10 bit, Audio sample rate=48KHz (to match original audio in video). All other settings default
SOURCE: DV via firewire (high-motion, skiing, artifacts appear while camera is panned). Additional audio: Music ripped from CD's. Please don't start on copyright issues ;)
PROJECT FLOW: From original timeline, produced a NTSC-DV-avi, Lower field first, Best Rendering Quality, Gaussian motion blur, Blend Fields
Then, dropped rendered avi files into a new project timeline, made no changes, and rendered as above to SVCD-NTSC.
PROBLEM: There appear to be 3-4 narrow horizontal bands (each maybe 20-40 pixels high)of interlacing artifacts (shimmering, etc - typical), while camera is/was panned. These interlacing artifacts are not everywhere on the video, but only in the same 4 narrow horizontal bands, equally spaced vertically, and running all the way across the screen. These appear to come and go, depending on the motion/panning taking place, but are in the same areas, consistently. I hope my verbal description of what I am seeing is coming across clearly...
When I first saw this problem, I rechecked original project settings, and I had failed to reset project properties from progressive (while I was grabbing stills) back to interlaced - lower field first, and thought resetting would fix it - NOT!
Now, I know SVCD's are not of the greatest quality but, I've been satisfied with results obtained for the last year or more with VF, VV3 and now V4, and have not seen this type of interlacing problems before. I haven't made any other system changes, other than installing a new external firewire HDD. Any ideas/direction?
