lower framerate simulation

PostMon Feb 06, 2017 4:09 pm

im re-creating this effect:


i think i know exactly how to do this except for one thing.

im still looking for a tool to simulate a lower framerate. and i cant just render out a lower framerate because i would like to have all/most of the serperate elements slightly offset.

in after effects, it's called ''posterize time''

any ideas?

I'm not in front of a computer but I would try double "timespeed" for it.

And brake concatenation if needed.

with timespeed i can get it to play slower, but thats not really what im going for. i want some frames to skip. for example: instead of frame 1 2 3 4 5 , only 1 3 and 5. or maybe more random.

you can use the "time stretcher" node with some animation orr expression in it

or take a look at the fantastic "time machine" fuse:

That was my idea:

            },
            Width = Input { Value = 0.1043812942002, },

double timespeed did it indeed. i thought i already tried that, but i guess i did it the other way around. stupid me :lol: life could be so simple :) ill also check the timemachine fuse. thanks guys!

You can use a simple expression in Time Stretcher:

Source Time = time-(time%3)

Where "3" can be replaced for any number of frames you want to freeze at each step.

With this expression, the time only changes in increments of "3" (or any number you want)
