How to shift Image plane in A:M-camera

[Bobby]

When I want 2 points perspective, I must set height image size than I need,
Can camera in A:M shift image plane?

I found it easy way in Blender, but I love to do in A:M.

Hi Bobby!

I believe the way you are doing it is the only way in A:M.  You might try a camera rotoscope to blackout the portion of the frame you don't need to reduce the rendering time spent on that part of the frame.

Not exactly sure what the difference to moving the camera on local axis is?
For that you just go to the top view, press 1, 2 or 3 (standing for x, y, z axis) and move around.

The other option is, that you go to camera view, press CTRL and the middle mouse button and move the mouse around if you want to do it in the viewport.
However this is not that precise.

Best regards

It is possible to use the "Render Animation Preview" button to render a portion of the screen to a file.  You could set up your overly-tall camera frame for the 2-point perspective you want, zoom in on that camera view, and then use Render Animation Preview to drag a bounding box around just the portion you need.

I believe you can make the render format and output location choices for this partial capture by setting them in Options>rendering and choosing "This Dialog"

Is it posible to Rotate X, but Y,Z not change? I don't know about function in Expression. Thank you.

X Y and Z are all separate values so, yes, it is possible to change just one.

But I'm not sure i understand your question.

[Bobby]

camera in Blender can do as same as shift film plane in view camera, so I think camera in A:M can do the same.

The rotate handle is part of the camera bone. It only shows the Z rotation of the bone.

Is there a big reason you can't render the large frame and then just crop for the portion you need? If there is nothing in the rest of the frame it won't add much render time.

Would the technacrane camera do what is needed?
