OSMMMTVD - SOFTWARE MOTION-VIDEO SUPPORT IN OS/2 2.1 AND OS/2 2.11 01/30/96 ======================================================================= Software Motion-Video Support in OS/2 2.1 and OS/2 2.11 ======================================================================= Please Read Entire Document for Full Explanation of Procedures -------------------------------------------------------------- DESCRIPTION OS/2 2.1 and OS/2 2.11 support the ability to play video and synchronized audio, and does not need special video hardware. Multimedia Presentation Manager/2 (MMPM/2) supports the Audio Video Interlaced (AVI) movie format using the Ultimotion or Indeo software motion video decompressor. RESOLUTION Ultimotion offers several advantages over other available software video technologies. Video Adapters -------------- Ultimotion movies can be played on any OS/2 system that has an SVGA XGA video adapter, with 256 or 65,536 color capability. Ultimotion can play back on VGA systems, although video quality is reduced when mapped to 16 colors. Minimal System Support ---------------------- This refers to playing a movie on a minimal system (such as a 386, 25 MHz system) directly from a CD, with 150 KB per second or less. Ultimotion supports movies playing at 15 frames per second with a size of 320x240 pixels, which is one-quarter screen size on VGA or SVGA systems. This is four times the resolution of other software motion-video technologies. Scalability ----------- Depending on the playback system, Ultimotion movies can be created with up to 30 frames per second, or at full-screen size, 640x480. All movies are created in a high-depth direct color space. If the playback system cannot support the movie as created, Ultimotion technology automatically scales the movie to match the system capabilities. If the processor in the playback machine cannot support the frame rate of the movie, Ultimotion scales the video down to match the processor speed. The audio plays back at the speed it was originally created, and the video stays synchronized with the audio. You can scale the movie larger or smaller during the playback by changing the window size directly, or by selecting options from menus. The Ultimotion decompressor plays the movie with 65,536, 256, or 16 colors, depending on the video adapter present in the system. With Ultimotion, there is no need to create separate movies with different numbers of colors; one movie covers all target playback systems. ______________________________________________________________________ IBM disclaims all warranties, whether express or implied, including without limitation, warranties of fitness and merchantability with respect to the information in this document.
