ok - let me explane to you original video was made with 50 fps with simple HD camera sony HDR-HC7e then, it was deinterlace with QS deintartlace then, frame rate was up with MSU_FRC (plugin for avisynth, avisynth - works under virtual dub) to 300 fps then - video with 300 fps was compressed by DivX 60 fps. because 300 fps - is very big file and i gess that your computers also as my - couldn't play such file. thats why some blur in video now i'm workin about it - how to delete blur.
