Extraperlate constant movement before and after keyframes
on Oct 25, 2018 at 10:11:39 am

Hello After Effects people.

I'm new to after effects, though I'm an experienced 3D animator with Blender.

I'm creating a video that will contain a lot of images scrolling past at a constant rate. From what I understand I can create a null and parent everything to it, but... is there a way I can set two keyframes - say at position 1 at frame 100 and position 2 at frame 200 and have the null move at the same constant rate both before frame 100 and after frame 200?

Thanks in advance,
Mike

You can use an expression. Alt+click on the stopwatch icon for the position property, then paste in this code:

if (numKeys > 1) {
if (time < key(1).time) loopIn("continue")
else loopOut("continue");
} else value;

Wow - I didn't think I'd be entering code so early, but you've explained very clearly how to do it - thanks!
