    Ok so I’m making a longboarding edit using Twixtor Pro in Final Cut and I filmed it with my T2i at 60fps. The tutorials that I watched told me to bring the clip that I wanted to slow mo into a new sequence and when I do that it changes the video to 30fps and when I add twixtor it gets choppy because Final Cut changed the fps. Any ideas how to get around that or a different way? I tried exporting the clip and re importing it but now its taking 40+ minutes to render. I really need to get this edit finished soon so don’t be afraid to post any ideas to so I can get back to editing.
    Thanks!

    Hi John,

    The Twixtor in FCP workflow is as follows.

  • First create a sequence (Which we will call SloMoClipSeq from now on) and make its settings identical to the Master Sequence.
  • Next add your clip to be slomo’d to the SloMoClipSeq. If it asks to change the seq settings say No.
  • Then add a Slug after the clip with the same duration. If you are going to slo by 50% add 1 of these slugs. If 25% add 3 of them, etc.
  • Back in your Master Seq, add the new SloMoClipSeq to the timeline.
  • With the SloMoClipSeq clip selected add the Twixtor effect and adjust its settings accordingly
  • That’s it in simple terms as I remember. Hope it helps.

    First off how do you change the settings to make it identical, and second is there a video tutorial that you like since I am more of a visual learner, but thanks

    Hi John,
    Goto your Master Seq and use Cmd-0 (zero) to bring up the seq settings. Make a note of the compressor, the frame rate, and so on.
    No jump to your SloMoClipSeq and do Cmd-0 again. Provided there are no clips in it you will be able to adjust its frame rate. You can also adjust it’s codec at any time.
    I will do a search for a video. I’ve not needed them myself as Twixtor has always been simple enough to understand from it’s included documentation.

    Does it matter that I have Final cut express and not Pro? because when I do cmd 0 it brings up the settings but what you say isn’t there

    John, I’m having the same problem, also in Final Cut Express. Whenever I apply Twixtor, my footage becomes very jerky, and oftentimes will have a lot of smearing, even though I filmed it against a simple background with no other motion.

    So…I don’t have an answer for you. But I thought I’d bump this post up a bit so hopefully someone who DOES have an answer will see it.

    (Just to note, I followed that exact workflow suggested by Sean above, and my footage still looks terrible. Not sure what I’m doing wrong).
