HD to SD flicking

i have a HD footage shot in Canon 5D, when down scaling it to SD i got some flicking when the camera moves.

im using quick time conversion to down scale the footage, tried every possible option, but still have the same problem.

when i play the quick time file using quicktime player it looks fine, but when i import it to FCP i get the problem.

i did try 8 bits uncompressed, none, pro res (all), upper, off fields, played arround with the time line settings, but all the same


in the past i had same problem, what i did is render the project as 1080i then render it back to SD, but that is too much render for long projects.

thanks i will try compressor, i fixed the problem using antiflicker filter, it made the image a little bit blury, but its only few wide shots, so no one woule notice :D
