Wierdness with PP2.0, Zoom, Color Correction at DVinfo.net

Patricia Lamm · February 26th, 2006, 11:54 AM

I've just migrated to PP2.0 + Aspect HD 4.0 and find the Quick Color Correction effect to be very nice. However, when this effect is implement after a standard PP zoom (from the motion effect) the Cineform HD Export avi file has wild ripples (extreme combing, only smoother). If I do the same Quick Color Correction and use the Cineform PZR zoom, then everything is fine.

OK, so use the Cineform PZR zoom only, yes? The only problem is that it's very difficult to pan/move clips using this effect -- the built-in PP motion effect is much better and more intuitive. Is there a way to use the Cineform zoom and the PP motion together? Once PZR is selected it seems to lock out the use of PP motion. (Only the PP zoom seems to cause the problems, not the PP motion alone).

Or, failing that, is there an intuitive way to map the coordinates given by a PP move (centered at 720,540) to the Cineform PRZ coordinates (-640 -> 640, -360-> 360)?

P.S. Welcome back, David. Are you getting any sleep these days? ;-)

Thanks, not too not much sleep. :)

This ripple sounds like fields are been combined from an interlaced source. Yes our PZR is field-aware, but I would have thought PPro's would be also. I'll do a couple of tests. However I first need some info from you. I guessing this is 1080i footage (not CFxx) or 720p. Was your 60i footage encoded as interlace or progressive (get the properties of the source clip.) In properties you should see the line : "Uncompressed Video Format is 8-bit YUV422 progressive" (or no "progressive" for interlaced.) Which do you see?

It's 1080i. When I check the properties it says "Uncompressed Video Format is 8-bit YUV422". The source was captured in PP1.5 using Cineform HD capture, so I'm assuming that it's interlaced upper field.

There does seem to be a PPro 2.0 bug (same does not occur with 1.5.1) so I looking into that and I have contacted Adobe. However there is a simple workaround; when using PPro's color corrector, add the Force Render filter after it. It seems added any CineForm filter will fix whatever the Adobe filter is doing wrong. ;)

Note: this issue doesn't happen when you use Aspect HD color correctors.

That's brilliant!! Thanks, it works great. I always wondered what I was supposed to do with "forced render". Any other great things that I should be doing with it?

Glad I could help. This one had us scratching heads at CineForm and Adobe. We have confirmed that it happens in Adobe alone, but we will try and find an easier solution than force render. Still explorering.

Force Render is handy when you overload playback with 6-7+ layers of RT video and effects and you force a render to get smooth playback. Force Render doesn't modify the image in any way.
