10.22. Multi-Tiled Movie (MTM) File Format

The multi-tiled movie (MTM) file format is designed to allow a single, large movie to be subdivided into a grid array of movies for playback in a tiled hardware setup using EnVideo. The mtm format also allows collections of images that match a pattern to be read as a movie, as a stereo image, or as a stereo movie. The mtm format also allows a pair of animations to be read as a stereo animation. Finally, mtm format can be used to simply play two existing movies side by side.

10.22.3. Example Tiling of Two Movies to Play Them Side by Side

MTM 1.0 
# 
# This is a Multi-Tile Movie file of full dimension (1400 x 600). 
#   with the first sub movie containing 700 x 600 
#   and the second movie containing 700x500 
#   NOTE: because the second movie is not as large in the Y 
#     direction, there will be a black bar above the movie 
#     denoting the mismatched pixels. 
# 
#  This allows you to play two movies of the same number of 
#    timesteps side by side.
