Setting the blur to 0 to the right inlet or switching the motionblur off by sending a 0 to the left inlet doesn't take the blur away any more. only re-loading the videos to the buffer makes the image unblurred again.

yes, Gem does most of it's operations "in-place", thus modifying the
incoming image rather than generating a copy. this is all for cache reasons.
if it's important for you to preserve the original image, use
[pix_separator] to force making a copy before mixing the pixes.
