Movie File Type Use this control to select the type of movie
- MPEG (using mpeg_create) - This uses an external
program from the University of California - Berkely. Each
captured image is saved to a file and the program "mpeg_create" is used
to create the movie.
- MPEG1 (using VTK) - This uses a VTK algorithm
to create an MPEG movie. Since each captured image is saved "in
memory", there appears to be a limit to how many frames may be captured
before running out of memory.
- MPEG2 (using VTK) - Uses VTK to create an
MPEG2 movie which may not play on all movie file players.
- JPEG Images - Writes each captured image to a JPEG
file that begins with the name "record_image". No movie is
created. Instead the user must use a third party program such as
Apple's iMovie or Microsoft's Media Encoder to create the movie.
