Hey Bernie,
Great, and thanks for the feedback. Yes the .01 wasn’t clear to me.
In short, what I did (please ask if that is too short):
I expanded the time-range to 37
I selected the Target and the Camera
The Keyframes in the Timeline (Standard view, the timeline on the button) shows then the Keyframes. I control (command) clicked on that key of Frame one and dragged it to frame 37.
In the Timeline window (keyframe) I selected all Keyframes and with the orange handlebar, I dragged on the right part of it, to place the keyframe 37 on frame 73 . 9Again reframe 37 is a helper reframe, other wise we would have no idea where keyframe 72 would be.
Then I used for both (at the same time) the (F-Curve) Function> Bake Objects… (Clean Baking to off!)
That would be all for the linear version
For the Spline interpolation some more steps are needed:
In the F-Curve Manger, I selected Target and Camera, and with the mouse over the curves I selected all keys (Cmd/A)
In the Attribute Manager, I set the Key Interpolation to Spline and the checked the Auto Tangent to get a nice short interpolation among all currently existing Keys.
The Clamp is set to off.
Now Bake that again as done above to create all the keys for each frame. If you really need for each frame a key, the baked version and the one created shortly ago should be identical.
I hope that works for you. Let me know if anything is not clear. Note that the bake Object will not produce a target tags, you need to set that up again.
=======
As a Side note, any animation path (F-Curve) can be converted into a spline and used as animation information. It might help in other cases. Just a thought.
All the best
Sassi
