For example, if the video source is 24fps, frame 0, 1, 2, 3, 4, 5......23, the target would be 0, 0, 1, 1, 1, 2, 2, 3, 3, 3, 4, 4, 5, 5, 5,....... I was using MPC-HC + ffdshow which has plugin AviSynth and added SelectEvery(2, 0, 0, 1, 1, 1) but the cadence is not alwasy 3:2. Some experts suggest me to use MadVR instread of EVR, it improves. Also I tried ReClock but can not get always accurate 3:2 cadence(With ReClock I have to disable the selectEvery script otherwise the frame sequence is odd, I was using a capture device verifying the unique IDs generated from the frame contents so that I can tell if it's 3:2 or 2:3 cadence. ) Could anybody guide me how to reach this goal? via some configuration/plugin or even source code customization? Thanks in advance!:thanks: Here enclosed a thread in another forum talking about the same issue:
