Camera Problems
Ok so i am doing a visualisation for a client and he wants the intial shot to be a top down view, the camera is then to pan down into the intial fly around shot.
My problem is that the cam seems to miss some rotation from frame 0 to frame 1, The H rotation on frame 0 is 0, and on frame 1 it jumps stright to 36. The other frame increments nicely at about 1.5degrees, yet this one makes the massive leap in one frame and looks very crappy. I have had this issue with cameras in all 3d programs. I really need a smooth rotation, Any Idea’s???
Thanks for your impending help!!

What’s it look like (the H parameter) in the the F-Curve editor? Is it a nice smooth exit from the keyframe or not?

yeah its smooth as it can be, u should try it out. make a targetcan, set the position values of cam and target to 0, then set the y value of the cam to lik 5000, add some animation and youll see what i mean.
Ihave overcome the poblem not by using a noraml cam but its not ideal!

Sounds like a problem with gimbal lock. Try putting the camera in a null with a different rotation and animate the null for the first move instead of the camera.

Gimble lock sounds exactly like what it is, and your idea sounds like it may work, but u say put in a null? is this a null object? and how do I create one?
thanks for your help

Yes, I was referring to the null object. You can create one by clicking the null icon (looks like an axis) in the modeling icons group, or throught the menu system: Objects>Null Object.

I’ve had similar problems with gimbal lock. I’ve usually just rotated the model around by 90 degrees and repositioned the camera accordingly.
Not an elegant solution but it gets you out of trouble quickly
