Stills flickering on cameramoves
Doing a documentary which involves me scanning in pictures then doing camera moves around the pictures. I scanned the black and white in at full res 600dpi. When rendered out I’m getting a banding and strobing during the moves. It looks like when you film someone with a black and white checkered top. I’ve tried the interlacing blur bit it just makes it look blurred. I’ve also added the flicker filter in FCP, but you can still see it. Has anyone got any advice.
Cheers in advance

TV is a horrible resolution, your picts are way too big.
Try downsampling them to the size you’ll actualy see on screen.

If you use the deinterlace blur on smaller sized pics it may not be as noticeable. When you have huge files you need to crank the blur up to 3 or even as high as 6 or 7 to get the deinterlace effect to work. If the pics are the resolution you need them for the scree and 72 dpi, a .5 – 1.0 should be enough to fix the problem. I usually would rather the pics be a bit soft than to have them vibrating all over the screen.
AND
TV is a horrible resolution! If your in SD no one except you (and maybe the client, but you can tell them that’s just how it is) will ever notice the blur. Especially by the time it gets re-compressed, sent to the satelite, re-compressed, beamed back down, re-compressed, sent to local stations, re-compressed, and delivered to the tube! I’ve seen stuff that in playback off the edit system rings like mad and no one ever fixed it. Then I saw the spots on TV and there was no ringing at all.

in addition to what has already been mentioned…
banding can usually be reduced by adding an adjustment layer at the top of the comp and adding a little noise, maybe 2%, monochrome. this technique is really just hiding the banding, but it does often work, and it is quick. another way (probably better way), is to work in a higher color bit depth… if you are in 8 bit per channel, try 16bpc (note, high color depth will increase rendering time)
as far as the strobing, if the movement is fast, the strobing may be lessened by motion blur and/or rendering with fields (know the dominance needed). motion blur will soften the images, particularly the ones moving quickly, and it will increase render time. rendering with fields well only help if you destination is interlaced tv, and it will double the render time. you can enable field rendering in the render settings from the render queue, just select the correct dominance.
