Is there a way to animate a camera along a curve at specific speed? There are two ways to animate a camera along a path:
1) Follow path Constraint and 2) Parent (follow path) command

But they both have the same problem: The speed of the camera depends on the length of the curve. I want to have constant speed between different shots and scenes.

The way around is of course to calculate the length of the curve and determine the speed that way but it would be annoying and extra work since I have multiple separate shots.

I'm not sure how you can do it with the standard tools, but I figured out a way using animation nodes that seems to work (someone might need to check my math). I basically created a subprogram that takes a Spline input and an object input(what will move along the spline). Then using some math, it takes the spline length, number of frames in the scene and a speed number and moves all the objects along their respective curves at that speed.

Maybe this will help you out, here's an example file.





edit: Thinking through this, you can probably replace the end frame value with just a float number set to some high number. That way this would keep the speed the same regardless of how long the scene is.
