What is the best techique or plugin for effective slow motion?

Right-clicking on a clip and adjusting time is not good. I have tried sending to Motion and adjusting the timing there but it softens the image.

Is Twixtor the way to go??

    Most people I know have got quite good results in Motion; have you tried the Optical Flow setting?

    What kind of footage are you editing and are you judging it after export from Motion or within Motion?


    I don't have Twixtor but a lot of folks love it, It's pricey but there is a demo if you want to compare vs Motion.


    Good luck.

    Depending on how much you are slowing things down, you may be expecting too much. If you are slowing more than 50%, the program has to fabricate intermediate frames from thin air.


    If you want to work outside of FCP/FCS, there is always AfterEffects.

    I'm late to the party but somehow I ended up here.  I'm reteaching myself this now.  I remember Captain Mench had a solution for this on the ProVideoCoalition site at one point for taking 60i footage and conforming to 24p using Shake.  The key element was Optical Flow, Motion uses OF as you know.  But I've just been doing a bunch of tests all night with some 60p (59.94) that we shot last week.  The CrumplePop tut is the one I've been following for Motion 4 and some random youtube stuff using Time Warp for AE tests.  The consensus seems to be each technique, including Twixtor, has limitations depending on the footage. AE better in one instance, Motion/Shake/Boris Red in another, Twixtor generally better than everything but still with flaws.  Let alone the other factors like did you shoot 60p to begin with?  Was the shutter 1/60 or 1/1600?  Other great tidbits like  this slomo conversion chart and this other Motion tut, 3 steps and bang!  I gotta go to sleep, hope this helps.


    Forgot this guy, of course he has some great tips from his friend on  using Twixtor.
