movie - reads script to control playback of frames on a Panasonic TQ-2026F videodisk or Sony LVR-5000 videodisk.  

SYNOPSIS


movie scriptfile
 

DESCRIPTION

movie reads the file scriptfile and interprets lines in it as commands to control the playback of frames on the Sony or Panasonic videodisk. It can be used to put together a movie to be dubbed onto VHS format videotape.

Valid commands in scriptfile are as follows:

search "framenum" searches to the given frame number. Valid "framenum"'s range from 1 to 43500 for the Sony, and 1 to 24000 for the Panasonic.

blank searches to a frame that had black recorded on it, i.e. it blanks the screen. It is highly recommended that any time search is performed, blank is called first to avoid noise in the image during the search.

playto "framenum slow videorate" plays frames sequentially from the current frame up to frame number "framenum". The current frame is either the result of search or the last frame of a preceding playto. The value of "framenum" may be less than the frame number of the current frame. In this case, frames are played back in descending (rather than ascending) order. Currently the only legal second argument is "slow." "videorate" determines the rate of playback. Frames on videodisk are displayed at 30 frames/second divided by "videorate". If the value of "videorate" is 2, for example, the resulting rate is 15 frames per second. A "videorate" of 3 results in 10 frames per second; a "videorate" of 5 indicates 6 frames per second, and so on.

hold "seconds" leaves the current frame on the screen for "seconds" length of time.

As movie is executing any comments (a line starting with "#") are printed out as they are arrived at, and when "playto" is encountered the frames to be displayed and the rate of display are printed out.

The following is a sample script file:

blank
hold 2
# Larry June's movie - February 27, 1989
search 5852
hold 4
playto 6400 slow 2
hold 3
blank
hold 2
