    Hi ****,

    with the gopro camera I have shoot a little attached video that seems a little jerky because of the 25 fps progressive.

    I wonder: is there a way, in avisynth (or other programs) to have a more smooth video?

    thanks

  2. Motion interpolation techniques can work well with video that doesn't have complex or too fast motion.

    You'll need mv_tools2 to use that function. It generates noticeable artifacts with your video though.

    my target, for the moment, is a SD monitor standard interlaced

    I try to understand if exist a particular avisynth script that can reduce the jerking in image, possibly without artifacts or minimum artifacts

  4. 576i25 TFF:

    Code:
    import("C:\Program Files (x86)\AviSynth 2.5\plugins\DoubleFPS2.avs") 
    
    ffVideoSource("gopro.mp4") 
    BilinearResize(720,576)
    DoubleFPS2()
    AssumeTFF().SeparateFields().SelectEvery(4,0,3).Weave()
    There WILL be artifacts.

  5. You can try adding motion blur with QTGMC to create 25 fps video that flickers a little less.


    Code:
    ffVideoSource("gopro.mp4") 
    BilinearResize(720,576)
    QTGMC( Preset="Fast", InputType=1, ShutterBlur=1, ShutterAngleSrc=30, ShutterAngleOut=360)

    If you didn't mind the speed-up, you could:
    Code:
    AssumeFPS(pal_double)
