Hi,
Frameblending is the method that is used for s-m-o-o-o-t-h slow motion effects.
basically if you have a series of frames of video running at normal speed ie:
1, 2, 3, 4, 5
if you were to do a 50% slow motion without frame blending you would have:
1, 1, 2, 2, 3, 3, 4, 4 , 5, 5 which results in a slight jerky effect.
with frame blending (which merges two frames to give an independent frame) is:
1, 1+2, 2, 2+3, 3, 3+4, 4, 4+5, 5
At least, this is what I think it means
Hope it helps,
Matthew
