Hi all!
I wonder if it is possible to have motion detection to modulate the strength of a temporal filter? This could be useful for analogue captured clips with still pictures like cartoons but also on normal movies.
We have the MAM filter which toggles between low motion filtered clip and fast motion filtered clip. We have CopySame and the dup filter that duplicates identical frames where no motion is detected. But is there a filter that averages identical (or almost identical frames) as long as no motion is detected? With a motion treshold it could be set up to do temporal smoothing of all no-motion-frames until motion is detected. I guess this would require some kind of frame buffering of the almost identical frames until motion is detected and then the filter is applied on the "almost identical frames". At high motion scenes the filter would be almost not used at all and where there is low motion or still pictures there would be strong temporal filtering.
I am not a programmer and also new to avisynth so this filter may already exist. Anybody is free to use "my idea" to make a new filter if you want. Perhaps there is methods to do this already?
Just an idea.
