Framing in the 3D World

Framing is the method by which you position and aim your camera so that your subject is within your camera's viewing plane or frame. When directors want something to be in frame, they are indicating that they want the object to be within an area that the camera sees. Your 3D application has some useful tools for determining what is in frame and what is not. Your 3D application has always had safe frames, but with it, you can now size all the safe frame regions to their own independent values. Plus, you can now mask out the area outside the outermost safe frame. you must learn the usage of safe frames, combined with safe-frame masking at a 70mm aspect ratio.


The result is that a giant model is framed properly for the "float-by." Simple framing involves positioning and aiming your camera properly so that your subject is in-frame, or at least poised to come in-frame during the animation. When framing your scene in your 3D application, you should always use safe frames if you intend to go to video. If you are not going to video, you can still use safe frames as a guide for making sure the action or subject is in a consistent location for an animation. For veteran computer animators, using the transform commands to position a camera and its target is second nature.

Your 3D application, however, incorporates buttons in the lower-right corner of the interface, providing all of the necessary commands for controlling a camera. Note that a camera view port must be active for these buttons to appear. If you are familiar with these buttons, then this might be a good time to explore using the new Expert mode for your camera view port. By using this mode, you can manipulate your camera or target through keyboard alternate as well as the transform type-in dialog. Composite framing is similar to simple framing, except for the fact that you are framing your virtual scene based on live footage that you want to match.

The footage, whether it is moving or not, requires that you make sure your camera's position, in relation to the background image, is similar to the real camera that photographed the real scene. As mentioned earlier, you can use Camera Matching for this particular operation, especially if precision is needed. Just keep in mind that you will need to have the proportions of the real photographed scene to be able to match up your virtual scene. With the usage of Camera Matching against a background you could produce the illusion of new office buildings in an empty lot.
