I like to tap the "C" key which allows me to cycle thru more intuitive Camera controls (with the mouse) the the Rotate XYZ options in the Cam Transform area.
Go to the beginning of your timeline. Reveal all the Camera Transform options. Turn on Keyframes for them all (just in case)
Move your timeline to a point where you want to Move Up and Tilt Down. Tap "C" and use the interactive mouse controls to pose the Cam. Since all attributes are already keyframed, they will be automatically created when you position the Cam with the mouse controls.
If you are using Two-Node Camera, you should not forget about Point of Interest.
For One-Node Camera manipulating Y Position and X Rotation or Camera Orientation should be enough...
Good point Fuzzy.
Thx lasvideo, using the mouse controls via the C key was better and I managed to get my title!
I'm still at quite a loss to what all the variables are doing, what is the difference between manipulating the cameras Point of Interest over it's position? And why does the camera flip round if I move it's Z paramter beyound zero?
So can anyone recomend a good tutorial on 3D camera work that goes beyound the usual just link a null object to move the camera, one that really explores how to do more complex movement
With a 2-node camera, the camera ALWAYS faces the Point Of Interest (POI).
The camera Position is the space the camera sits in the "world".
The POI is the point within that "world" that the camera lens is pointing to.
If you move the POI downward in Y space, the camera will effectively rotate downward to follow it - but that rotation will not be represented in the camera's rotation parameters. The camera's rotation parameters wil be ADDED to whatever the POI forces the camera to do.
If the camera passes the POI in Z space, the camera instantly flips so that it is still oriented towards the POI. If the POI is confusing you, just switch it off in Auto Orientation settings and work with a one node camera until you get the hang of it.
Your welcome FF. Andrews statement does a great job of explaing the idea of a 2 node camera. This can be turned off in favor of a 1 node camera. which has no POI (point of interest) function. Play with each to see which you prefer.
When doing complex moves with AE's 3-D camera I always put my camera on a dolly. I also attach the point of interest to another null. This makes complex moves much easier. It also provides a way to easily animate the focus and the point the camera directly at what you want to point ot at by animating the position of the POI null.
Here's a screenshot of a simple timeline setup. The two 3D nulls are named Dolly (at the camera position) and POI (for point of interest)
Here is the animation preset that I use to tie the camera's point of interest and focus distance to the POI null. The expressions work with or without parenting.
The camera Point of Interest expression:
poi = thisComp.layer("POI"); fromWorld(poi.toWorld(position))
The camera Focus Distance expression:
C = thisLayer; POI = thisComp.layer("POI"); cp = fromWorld(C.toWorld([0,0,0])); fp = fromWorld(POI.toWorld(position)); length(cp, fp)
This technique makes animating a camera a lot easier.
