Extrapolation in AE

[Simon Bonner]

Not used Shake or Flame, so don’t know if this is exactly what you need, but Dan Ebbert’s site shows how to make curves using expressions.

Hey Simon

No, that wasn’t what i meant, although it was a great link. Thanks.

I’ve uploaded some screengrabs from Shake at:

Hope it explains what I am trying to do.

Thanks,
John

To get the the graphs of the keyframes twirl down that property.

So if those graphs you’re showing are for Opacity, “T” reveal the opacity stopwatch and keyframes. Twirl down that little triangle next to the Opacity Stopwatch. If they’re Hold Keyframes there will be a Step pattern, if Bezier Keyframes they’ll have Bezier Handles to adjust the curves.
The newer versions of AE have an advanced Graph Editor, see this for a tut:

Oh, yes, F9 on select keyframes makes them Bezier, Right-Click >Hold Frames makes them Hold Frames. Otherwise use Animation>Keyframe Assisstant>Interpret Keyframes.
