Video Fforward blending effect?

    May 03 2014 | 8:35 pm
    I believe these videos are editing in a film editing software.
    I would like to make a patch with fast-forward jit.qt movie in this blending effect in a realtime. This effect in max would be sort of frame blending. (overlay, bleed etc.) I am going to use a small video file, but wish to make this effect while not consuming too much graphic processor that leads to have freezing. Rate control consumes cpu and gpu I believe?
    I planned to control ONLY the video's 'playback time' with this blending effect. not adjusting frame by frame slide.
    Can anyone help me?
