slow motion
Hi.
I have a problem with slowing down footage in FCP. For example 75% speed makes irregular double frames every 4 frame and it makes footage looks juddering or steppy.
I was trying to do it in Compressor setting frame control timing to motion compensation but it makes strange blending or artifacts.
Motion has optical flow but no settings and it looks morphy.

Motion does have settings. You can set the type of image analyzation.
Optical Flow tends to be ‘morphy’. Also, I’d suggest trying different types of analyzation in Compressor, not just best (or optical flow). If none of that works, try a plugin like Twixtor which is built just for this and has ways of dealing with morphing.

Thank you guys for the respond!
Footage is 25 fps, DVCPRO HD 720p50
Twitor is quite costly Jeremy 🙂 … i am watching now overview from the link you provided.

Yes, but if the built in tools aren’t doing it for you….then it might be worth it.

I have often found that turning off the “Frame Blending” option in the FCP slow motion window solves blurs and smears. Perhaps try that before whacking out the dollars.

I agree with Jeremy.
Twixtor allows total control because you can key-frame all the parameters.
With Motion or Compressor you can not and sometimes the results are horrible.
