-
-
- Yes, there is a better way, and best of all, no
- Macintosh is necessary.
-
- Get yourself a copy of IRIX 4.0.5, and the Media Mosaic
- software package. Included are two programs you will
- find very useful: moviemaker and movieplayer.
-
- Movieplayer plays back compressed digital movies, just
- like Apple's Quicktime movie format. Your movies may
- also have an optional mono or stereo soundtrack (of
- course, you can hear the soundtrack only on IRIS
- systems with audio).
-
- Moviemaker will combine a series of image files, together
- with an optional sound file, into a movie file. You can
- also edit movie files, decompose movies into images and
- audio, and even perform simple image processing on the
- individual frames of a movie.
-
- The latest release of Moviemaker (which will definitely
- be included with the Indigo R4000, I'm not sure when it
- will be available to all) now includes a graphical user
- interface. You can view the entire movie, together
- with its soundtrack, as a scrollable "filmstrip"
- onscreen. You can select regions of the movie with the
- mouse and edit the movie with Cut, Copy and Paste
- commands. Also included is the program "svtomovie",
- which will record live video off the IndigoVideo board
- into a movie file.
-
- Finally (and this may be of interest to you), the
- program "imgsnap" (part of the ImageVision Utilities
- software package, and free with the system) has been
- enhanced to automate frame grabbing, in order to work
- better with the movie tools. To create a movie from
- Insight, you might do the following:
-
- 1. Start imgsnap, sweep select the
- region of the screen you wish to
- capture as a movie.
- 2. Click the "Save in Same File" button.
- Now imgsnap will save consecutive images
- in the same image file.
- 3. Click the "Save" button each time you
- want to snapshot an image.
- 4. When done, start up Moviemaker. Choose
- "Insert" from the menu.
- 5. Click on the image file in the file
- browser. Choose "Accept." Moviemaker
- creates a movie from the image file and
- presents it in the display. To view it,
- click the "Preview Movie" button.
- 6. Choose "Save" from the menu. Name
- your new movie.
-
- Contact your sales rep for availability of the Media
- Mosaic package. Release 1.0 is currently available,
- though the new release (which is just now in the
- process of release to manufacturing) should be
- available soon. Much of the release is specific to
- Indigo and the 4D/35, however the movie tools should
- run on any IRIS system.
-
- Hope this info helps.
