progressive screengrabs to uncompressed interlaced SD

Hello!

Any help with this little problem would be much appreciated

I've captured some screengrabs from the internet with iShowU into Apple Animation 1920x1080 at 24p (as I didn't want this program to interlace or scale anything).
I've then imported these into an uncompressed PAL SD (FHA) Motion project in order to pan and zoom around it.
Then I rendered these out as uncompressed PAL SD quicktime files (upper field dominant) and dropped into an uncompressed PAL SD anamorphic (upper field dominant) timeline.

However! When I play these back on my PAL SD SDI broadcast monitor (an old grade 1 CRT) I still get a bit of flicker on the pans and zooms. I realise this might be the thin lines on the website rippling over the interlacing but am I missing anything else?

Dropping in the .motn files into the FCP timeline and rendering produces the same thing. Have I missed a checkbox somewhere? Should I be using compressor?

Any thoughts/questions would be really useful.

Thanks!

Paul G

In FCP I would add a Flicker Filter to the file to get rid of the flicker. Hope this helps.

Hi Stephen,

Thanks for your help - doesn't the flickr filter do a deinterlace or blur? I don't want a drop in quality but if this is the only way... Incidentally I just rendered out some PAL DV video from motion as uncompressed PAL SD and this has the same flicker on it - I thought Motion would shift the fields for me...

The flicker filter adds vertical softness. Those darn thin lines are doing you in. Another way to get rid of them is to zoom into the web page further so the thin lines become thicker. Hope this helps.
