Smoother Keyframes
Hello everyone,
Having a really hard time making my keyframes smoother, any help would be greatly appreciated.
At the moment, I’m trying to make a similar parallax effect to this: https://www.youtube.com/watch?v=3AbejeKd9Nw
I’ve got the parallax down, but now I’m having trouble animating the camera. I’ve got 4 keyframes (image attached) with a steep position ease out, then linear keyframes, then finally a steep ramp out again. However, the point where the ramp ends and the linear keyframes begin, is very noticeably unsmooth (again, image attached to help illustrate my point).
As you can see in the video example, the camera does its movement, then there’s linear travel, then it does another big movement, but it’s all seamless. With mine it looks very choppy (as if the camera moves, then stops, then starts again each keyframe if that makes sense?).
I’d imagine it would be a lot easier with the value graph editor, but that doesn’t work very well with position keyframes.
(Also, as a sidenote – this also happens to me when I try and do this with my shapes and text in my everyday workflow, but I’ve just chose to ignore it or spend ages working around it)
If you’ve read this far and haven’t left due to the frustrations of reading my poorly written question, then I appreciate it 🙂

I’ve managed to recreate it with scale, like so:
but again, not sure how to do this with the “speed” graph editor for the position.

Try the Separate dimensions command:

every keyframe has incoming and outgoing velocity, if you match this value to the speed of your linear motion you’ll see no bumps. Essentially just pull that point up to match the velocity line and accentuate the handle’s influence so you get more easiness in.
Just keep in mind that your temporal interpolation has nothing to do with the spatial interpolation, so you’ll need to give some smoothness to that curves too if you’re animating in more than one dimension. (this too is usually the problem with bumpy movement when animating cameras in 3d space)

Sorry, I’m having some trouble picturing this… would you mind maybe posting a screenshot so I can understand what you mean?
Thanks!

I’ve tried that before, but matching the speed of two dimensions perfectly is really difficult…
Also, working with 3 different easy-ease curves is messy, especially when you introduce multiple layers that need to be matched simultaneously. I was hoping for a more efficient method, never mind.Thanks for the help though, I might just have to do this 🙂

You should right click a keyframe and choose keyframe velocity, If you match its incoming and outgoing velocity (or check continuous) you should see no speed alterations within that keyframe’s frame. After that you just need to increase the keyframe’s influence to get a more smooth transition between the speeds.
