I think we are talking about different things. Increasing fps is pretty meaningless, if the clip is never played at that exact framerate, which applies to a lot of video. You only change the content of the frames for no sensible reason by smooshing in "wrong" pixels. Furthermore, I really don't see the point in adding inbetween frames at the cost of reducing overall sharpness and getting that floaty feel. The resulting frames are never physically exact, anyway, as neither their direction sampling nor their timing mimics a true shutter. Call me old-fashioned, if you will, but I truly don't see any use case for this. In mixed media projects, there may be conformed clips, but nobody would treat all footage just at whim. If this is some requirement for a specific delivery system, then okay, but even then I would assume that just doubling frames looks better than interpolating them. Anyway, your issues are very likely due to not obeying pulldown cadences, which naturally occurs when going from 24fps to 30fps/60fps. Check your footage interpretation on that one. Also verify, that your cam actually shot 24fps, not something else, including possibly "fake" 24fps based on 60fps with tagged frames... Mylenium
