Hello everyone,

I want to animate my camera like the way we can see in these videos:

from slow to rapid movement transition and from rapid to slow again.

I pass a lot of time in lightwave during last days to try to manipulate all the camera setting, keyframe, null target... but without a convicing result :( someone can help me on that, any free camera setup to share with me just to understand what I'm doing wrong?

Thanks

It's called time ramping and it's done in post. You should figure out what your slow speed is going to be and do the whole sequence at that speed (just how slow you choose to move things, not talking camera speed), then you can time ramp (time re-map) various sections to fit the edit/music. It's best to do it in post so you have the freedom to have this effect whenever you choose, if you try to animate it that way it's all locked in and it's going to be hard experimenting.

I'm going to go out on a limb and suggest it's probably done in post. Not saying it's impossible at the render stage, but RE:Vision Effects make a plugin for After Effects and other packages called Twixtor. Got me out of a sticky situation on more that one occasion by tweening between frames to make an animation last longer :)

Edit: I see Mr Waterman beat me to it :thumbsup:

I think I will make all the animation at a slow speed and use in AE the temporal extension to make it faster when I want to be.

It can be done in post, but if you don't have the time to render out your entire animation at its slowest speed (for speeding up in post), you can do it simply in Lightwave.

Just bake all of your animation to a .mdd file, then you can use one of the dp kit nodes to keyframe the movements very fluidly in a graph editor. Then you can render out in one go with a camera move which doesnt get sped up the way your objects would.

The problem with doing it in post is that any camera move you have in your shot gets sped up also.

And how can I do a smooth curve path instead of having these hard transitions? I have tried to play with graph editor and use bezier instead of TCB spline but it don't give the result I want.

It looks like your keyframes are set to linear. Here, I have made only two keyframes, set to Bezier spline, which I can use the handles to get a nice smooth curve.136174

The frame 0 just don't want to obey to the bezier curve... same thing on each axis

ok I just found that the 2 keyframes at both ends needs to be bezier. It's not really friendly user.....
