keyframe pre and post infinity?
Looked around and haven’t found info on whether there is a way to make keyframes continue into pre and/or post infinity.
As an example, i have two position keyframes on a layer and I want the motion to continue at the same rate before and after the keyframes.
In a package like Maya, I can grab the last keyframe and set its post infinity setting to loop with offset and- even tho the curve has ended- it continues moving at the same rate as if that curve continued on the rest of the comp.
thanks!

Hi,
Yes, you can do this with a little expression added to your property.
loopIn(type=”continue”);
loopOut(type=”continue”)This bases the value on the velocity at the first or last keyframe. You can read a bit more here.
Hope that helps,

Thanks! I will give it a go!

i feel sort of silly, but for whatever reason, with the syntax, which seems from my research to be correct, i can only get pre and post looping to work with one or the other, not both.
if i use:
loopIn(type=”continue”);
loopOut(type=”continue”)then it seems to ignore the loopIn and if i do it in the reverse order, it ignores the loopOut. in other words, it always ignores the first argument and runs the second.

Hi again,
Sorry I didn’t reply to this sooner – I just didn’t see it :-/
Stick this in as your expression:
if (time-key(1).time<=0) {loopIn(type = "continue")} else loopOut(type = "continue") That should work. Cheers, Ben Curious Turtle Professional Video

Just a quick one but I’ve been looking for this solution for ages!!! Thanks so much Ben. I’m going to have a proper look at it and try and understand the principles that it works by – I’ve never used the…
if (time-key(1).time<=0)
… expression before.
And thanks for that Adobe link. It’s great.
Jim
