- -------------------------------------------------------------------------
- Documentation of DOS VCR features and controls, as well as warnings
- about use. This VCR application uses the Motive library developed
- by Media Vision for DOS playback of AVI movies.
- -------------------------------------------------------------------------
- VCR currently requires Media Vision Pro Audio Spectrum or Thunderboard/
- SoundBlaster v2.0 hardware and a VGA card, preferably one using the
- Cirrus Logic 542X chip or supporting the VESA VGA BIOS Extension
- (VBE v1.2). VCR plays back movies recorded in AVI format in one of
- the following video formats:
-
- raw 8/16/24-bit video
- MS 8-bit RLE video (<64K per uncompressed frame)
- MS Video 1 (Media Vision ALF) 8/16-bit (<64K per uncompressed frame)
-
- VCR plays back movies recorded with 8 or 16-bit audio at 11kHz, 22kHz,
- and 44kHz, in mono or stereo. Note that video playback quality will
- be severely degraded at the higher data rates.
-
- VCR can play off of a CDROM, provided that the file is compressed for
- a data rate of <=150K/sec.
-
- To run VCR, type VCR, followed by the filename:
-
- VCR f:\space\8_bit_90\voyager.avi
-
- VCR will immediately start playing the movie. While playing, there are
- several VCR-like commands available on the keypad.
