unwanted ripples
I am making a video in FCP using etching stills. When I make them move, the horizontals ripple, even though I have deinterlaced the clips. How do I calm this down?

Try changing the motion filtering quality to BEST. This sometimes can dramatically increase the quality of positional changes or scaling in Final Cut when things are rendered.
To do this go to Sequence Settings > Video Processing tab > Motion Filtering Quality > BEST.
I think you need to make sure that you render out the pieces that have motion changes involved… at least give it a try. If it’s still not looking right and it’s not making you render (because it’s “full”) then force it to render items on your timeline that are “full”.
Oh and fyi it’s best to always set the motion filtering to best in Final Cut, but not until right before you’re about to master or output. This is because the rendering goes slower… so I usually work with it set to Normal, and then change it to BEST at the end. Sometimes I forget though… :]

Thanks,Paul, for that important information which I will use for all stills in the future. But I tried it and it didn’t solve this problem. I’m using a Goya etching with horizontal ripply lines over which I move down and across, causing the ripples to come alive like water. It’s lovely but not what I need. Any other ideas?

Hmm… I know you said you tried to de-interlace and still have the problem… have you tried the flicker free filter? Try playing with the settings on that, possibly with and without the de-interlace filter still applied. See if that gives you any sort of improvement.
Is it possible to send a screen shot? Or is the problem only visible when viewing in real time?
Also, are you noticing the problem on a broadcast output? Or just on your monitor when working in Final Cut? Sometimes the computer screen doesn’t give you the best indication of what is actually being displayed if your attended output is broadcast. Also, make sure that your canvas is at 100%. Sometimes scaling it down gives you strange visual effects that aren’t actually there in the video.
Let me know if any of this helps.

Well, I did everything you suggested in all combinations, and there’s still no change. I assume that when you said “flicker free filter” you meant the flicker filter in Video Filters–Video.
I can send you the still (2.2MB) but you would need to make it move (starting in somewhat and zooming out as you move from right to left), but that would take time and I don’t want to impose.
I may just have to use stills with fewer problems.
Thanks again,

By the way, Paul, I transferred it to DVD using DVD Studio Pro at hihest resolutiion, and it looks the same on the TV monitor.

What you’re seeing is probably interlace flicker cased by the fine detail in the etchings. Deinterlacing won’t solve the problem, because the still images of the etchings themselves were never interlaced to begin with. You’ll have to blur the pictures slightly. Add a Gaussan blur at anywhere from .5% to 2% & see if that fixes your problem.
