Question regarding scaling the length of a timeline?

[llamadoH]

I set up a timeline at 60 seconds for testing purposes. Now that I have it working properly, I want to scale it to the correct time length, which is probably around 1000 seconds.
How can I scale the timeline from 60 to 1000 while keeping all of the keyframes on the timeline at the correct proportions from one another? Or do I have to manually adjust each keyframe?

You can dilate the timeline by setting its Play Rate, in this case it is set to 0.1, making it last 10 times longer. To make 60s last 1000s, you’d need to set it to .06, I think.

Alternatively (the bottom example), you can define external curves and feed the timeline.
