transform

The generic term for both a transition and an effect for Windows Movie Maker, used to enhance visual content.

video buffer A

The first input buffer for a transition, or the only input buffer for an effect. Effects read each pixel in this buffer for every frame and write the result into the output buffer. For transitions, this is video being transitioned FROM. Windows Movie Maker uses 24-bit RGB natively, though 32-bit may be used in a DXT.

video buffer B

The second input buffer in a transition. This is the video image being transitioned TO.
