About Resize

When working with clips of different resolutions, you will sometimes need to resize clips. Use Resize to change the resolution of a clip and its frame bit depth. Typically, you resize clips in these cases:

If you want to load mixed resolution clips into a module (as front, back, and matte clips), you must use Resize to make them the same resolution or the module will not accept the input clip selection.
If you want to load a front and matte clip that are not the same resolution as Action media, you must use Resize to make them the same resolution or Action will not accept the input clip selection. Different Action media can be of different sizes—only the front and matte of each media must be the same size. You can get the best results by keeping the original resolution of all clips in Action and then resizing them using Action 's axis transforms.
If you have a master clip of your project's default resolution, you can resize the master to deliver to other resolutions.

Resize includes a crop box that you use to define the region of the source clip from which the resize sample is taken. Use the crop box to pan and scan 16:9 masters to a 4:3 delivery format.

You can animate the frame size of a clip, provided the result is used as an intermediate process in Batch. For example, you can animate the frame size of a clip and feed the result into Action media. You cannot output a clip that has anything other than a constant frame size from frame to frame.
