    We’ve all had it: a client that did not shoot progressive, but wants perfect slowmo on his interlaced footage. 50% and 75% slomo’s needed, and FCP’s slowmo makes the footage soft with field blending.

    Options:
    Twixtor
    re-time
    Compressor 2 with motion estimation
    Avid Fluidmotion (symphony only)
    Shake 4 optical flow
    Graeme Nattress’s G free fifty

    I know most of the above will work well with progressive footage, but which of them will work well with interlaced?

    Regards
    Francois

    I can vouch for the Compressor method. Very smooth…

    Have you tried dropping a de-interlace on the slo-mo’d footage?

    Shake4 with optical flow works very well with interlaced.
    Actually you’ll get much smoother motion with interlaced than with progressive, since the frame rate is double.

    You left off Boris Continuum Optical Flow. Very nice smooth slo mo’s in FCP.

    I use a lot of slo mo for action sport videos and here’s what works. Use FCP change the speek to whatever you want. UNCHECK the Frame Blending option. Then apply the deinterlace filter to reduce the strobing. This give very good looking slo mo for action sports stuff. Is just as good as twixtor. Don’t know about the others. some of the programs that “create” intermediate frames don’t really do that good of a job when there are lots of pixels that move in the shot, as is the case in action sports. the might work very well in a slo mo of somebody walking down the street or eating a chicken wing.

    [Trevor Ward] “This give very good looking slo mo for action sports stuff. Is just as good as twixtor.”

    Now your method might create a good looking effect, but you can’t compare anything that FCP does to Twixtor. There’s not a whole lot out there that compares to what Twixtor can do with speed changes, hence the price tag.

    But your method probably does yield some of the best results that FCP can create.

    The free 50 was just a test for comment. Try G Map frames in Standards Converter for lovely 50% slowdown of interlaced footage. It only does 50% mind you, but it’s lovely.

    I did tests with my footage (DVX100a, 60i) and compared all the different combinations of settings in twixtor with the ones in FCP. For MY footage, my FCP method was better than twixtor. Used a monitor and not just the screen. I think someone needs to test their methods with their own footage. My footage was wakeboarding. The rider is traveling at 25mph past water and trees and sky all while doing fast, twisting flipping motions. the twixtor footage either distorted the rider, or the trees or the water, or blurred areas that moved too far from frame to frame.
