drunken master : la propia tecnica

delante del espejo...
inspired by bob weisz' cool " how to datamosh " ( http://www.youtube.com/watch?v=tYf3EWMuHH0 ) i tried out some similiar techniques. But instead of using the "real" compressed i and p frames, i used only the motion vectors of one clip and applied them to another image (except the first bit, which is "genuine datamoshing") . sometimes it looks a bit like the style of the great takeshi murata. I used avidemux, avisynth, virtualdub, and - for the calculation of motion - the mvtools that have been mainly developed by fizick and manao ( http://avisynth.org.ru/mvtools/mvtools2.html ). the avisynth script should go something like this (you might want to play around with the variables, especially "recursion", "blksize", "overlap". And be sure to use mvtools2 that have the nice recursion option again - which is essential for this technique.)

# 41sttry 2009
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\mvtools2.dll")
o_clip = AVISource("E:\video\clip41.avi")
image = ImageSource("E:\graphics\bg41.jpg", end = 41, fps = 25)
image = image.ConvertToYV12
super_clip = MSuper(o_clip, hpad = 0, vpad = 0, pel = 1)
mv_clip = MAnalyse(super_clip, blksize = 4, truemotion = true, overlap = 2)
super_image = MSuper(image, hpad = 0, vpad = 0, pel = 1)
result_clip = MCompensate(image, super_image, mv_clip, recursion = 100)
return result_clip

great it works . is there a way to use a video clip instead of a static bitmap ?

[41sttry]

well, the fun thing about the use of mvtools is actually that the traces of motion of the applied video is accumulated (that's what recursion is basically) in one "static bitmap" which gets more and more out of order. as the first thing to try out i would recommend to produce another videoclip with the exact same properties as the original clip and use it as "image" (it has to be something like avisource() of course then). then first try different values for recursion (e.g. "recursion = 50")

[41sttry]

to get both; two videos and disorder, you could try to mix the technique applied here with the "original datamoshing" way. for example "interleave" the frames of the two videos in avidemux, and then apply the mvtools-script to the result, with the first frame of one of the clips, and maybe recursion = 90. I haven't tried that myself yet, so good luck ;)

Is there a way to access that static bitmap in which recursion accumulates?

I want to be able to render it ..see it and replace it directly .I imagine it as an image with some motion vectors looking like particle trails.
