Timeline / Lerp / Distance / Speed / Time / Maths... ?

Mistake in my maths above, so the initial playback speed of 1, divided by 3.3333 would be 0.3, thus slower not faster…

BUT…

How do I know how much distance has actually been travelling in that 1 second length of Timeline? That alpha that is generate for the Lerp? How do I know whether the value of 1 is correct or whether it should be something else?

It strikes me that if I could just put in the actual values this would all be so much easier… if I could then the playback speed would be 1. The length would be my calculated duration of 1000/300, thus 3.33333. The first keyframe would have a value of 1000, and the second would have a value of 0 and be at 3.3333 seconds on the Timeline. Yet I can’t do any of that.

…and should I also not be concerned about using DeltaTime in all of this somewhere to make the movement frame rate independent?

Sorry, only just saw the bit about delta. You only need to compensate for delta time when using interp nodes. The great thing about timelines is they always complete in the correct time regardless of frame rate. Here’s a good vid about it:

Nope, can’t find it right now, but there’s a good vid on this channel:
