Increasing the speed will only look perfect when you go to 200 or 300 %, otherwise the system has to skip an uneven amount of frames to get it right. Say you put it to 120 % speed: Then one in five frames is skipped and that makes for jerky motion.Some editing softwares have special algorithms. In Final Cut Pro it's called "Optical Flow": The whole motion is analyzed and put back together.
It's even harder for the software to slow footage down. If you want good slow motion you should record in a higher frame rate. If your final product is supposed to be in 25 frames (typical for Europe) then if you recorded in 50 frames per second you can slow it down to 50 % (exactly 50%!) and it looks buttery smooth.
Hmm.. yes it has a logic, I will try.
But it does not happen to all the captures, this is what it puzzled me.
Thanks a lot for the explanation. |
