Can Camera speed along a path be controlled?
show user profile  dry_erase
Is it possible to control the speed of a camera along a path, in the same way that it's directional velocity can be controlled; i.e. graphically? In other words, is it possible to manipulate a graph of speed, in a way that the total time of the animation will be changed when it is manipulated, but so that acceleration can be carefully guided through a move? Otherwise, what is the best way of controlling camera speed and acceleration along a path... Any thoughts helpful... thanks!!

assign your path constraint to the position track and then assign a bezier float to the percent track

I think a graph chart should do this well.

Thanks Mak - any chance you could explain in a little more detail how to do what you've suggested?

you sure you dont want to give Curve editor a shot? F1 "curve editor". its alot more flexible

You should use the curve editor for this. I think that is what Mac means, but instead of having linear keys, you need to use bezier float ones so that curves are smooth to allow for smooth acceleration and decelerations.

Basically, keyframe the percentage of the object on the path constraint. For instance, set one key at 0 percent and another at 100% and the object will travel the full length of the path. If you move the keys closer together the object will travel the path in a shorter time. If you use linear keys, the object should travel the path at a uniform speed, however if you use bezier keys, it will slowly accelerate at the start, then slowly decelerate towards the end.

If you want to control the speed at some other point in the animation, simply add more keys for example, at 25% - 50% - 75% and slide them closer or further away from each other to slow down or speed up the animation.

yah, use curve editor..open it up(after using a path constraint), find the percent track and assign it a bezier float controller..bezier float will give you precise control over in and outs between key frames
