twixtor – bad quality
i am trying to change the frame rate of some canon 5d footage 1920×1080 at 30p to 25p 1920×1080 in final cut pro. i’ve converted the 5d footage to 25fps in compressor without speed change to get a clean 25fps footage master, which is at that point obviously too long though. then i took this footage into final cut and applied the twixtor effect with a speed change of 120% to get the correct speed in 25fps. the sequence is set to uncompressed 10bit 25p.
when i apply the twixtor filter though, the quality of the image immediately drops and i see jagged edges all over the image. it looks like twixtor drops half of the quality of the original image to do its task.
what am i doing wrong?
thx for your help

First: I presume the frame rate converted footage doesn’t look jaggy, correct?
Sounds to me like Compressor marked the footage as interlaced when it should be marked progressive.
Take a look at the item properties for the footage. Right-click (or option-click) on the footage in the bin and select Item Properties->Format… Make sure it says “None” for “Field Dominance”. If it says Upper or Lower, right-clock where it says upper or lower, a menu will appear and choose “None”.
You’ll then need to drop your clip into a new sequence, so that the sequence and the clip within that sequence gets marked as “None” for Field Dominance. Apply twixtor again and set the speed to 120%.
If that isn’t your problem, send a 10 to 20 frame SOURCE (before Twixtor) clip to us at techsupport (at) revisionfx (dot) com, and and FCP project that shows the problem when Twixtor is applied.
