- QuickDAT™ and datTime™
- ——————————————————————
-
- by Richard Zulch and Stephan Somogyi
-
-
- conceived of and written entirely during MacHack '93
-
-
- What Is It
- ——————————
-
- QuickDAT is a tool to move (not copy, move) the contents of a QuickTime movie
- onto a DAT tape. It uses Retrospect 2.0 (or later, I guess) as an engine; it
- will not work stand-alone.
-
- datTime is an INIT (that does work stand-alone) that allows you to play back
- the movie stored by QuickDAT.
-
-
- What To Do
- ——————————
-
- Moving the movie to DAT:
-
- - Make sure you have a DAT drive connected, that it's on, and that it has a
- tape in it. Any contents of the tape will be overwritten -- you've been
- warned.
-
- - Double-click on QuickDAT; this will launch Retrospect.
-
- - Choose the movie you want to move to tape.
-
- ••• QuickDAT will irrevocably change the selected movie file -- don't use
- QuickDAT on a movie that you don't have a backup of! •••
-
- - Depending on the size of the movie, the process of moving may take quite
- some time. QuickDAT will show a progress indicator while it's moving the
- data to DAT.
-
- - Once the movie's data has been moved successfully, QuickDAT will delete the
- movie information from the original file. The resulting file will be much
- smaller than it was before. However, keep the resulting file around, you
- will need it to play back the movie from DAT.
-
-
- Playing the movie back:
-
- - Make sure you have QuickTime installed and that the datTime Extension
- loaded at startup. You can see for certain whether it loaded successfully by
- watching for its little icon at startup. If an error occurs, the little icon
- will have an X through it.
-
- - Make sure that the DAT drive is connected, that it's on, and that the DAT
- with the movie data is in the drive.
-
- - Double click on the movie file.
-
- - That's all; the movie should play, and scooting the little QuickTime slider
- around should work as well, albeit slowly.
-
-
- Technology Caveats
- ——————————————————
-
- QuickDAT (and therefore datTime) will only work on movies that are completely
- self-contained. We have no idea what will happen if you try this with a movie
- that has external references. We don't recommend that you try it and find out,
- either.
-
- DAT drives (and tape drives in general) are not random access devices.
- Playing a QuickTime movie sequentially will work just fine. Jumping back and
- forth will be really, annoyingly slow.
-
- On the other hand, you can now store about 2 gigabytes worth of movie onto a
- $12 DAT tape instead of storing a 1 gig movie on a $1200 hard disk.
-
-
- Disclaimers
- ———————————
-
- QuickDAT and datTime function well when used within their operational
- parameters. This is to say that we got it all to work on the machines (and
- with the DAT drive) we developed, debugged, and demoed on. If this software
- works for you, more power to you; if it doesn't, don't blame us. If
- something (anything) bad happens as a result of you trying to get it to
- work, it's not our fault. After all, it's a hack.
