- Has anyone considered doing for analogue video what PCs did for
- computing? How feasible would it be to enhance existing analogue video
- technology for flexible and more personal use? What I had in mind was
- continuously variable play back speed from the storage media (continuosly
- variable raster scan rates).
-
- Fast and slow motion film already has countless applications. It would
- seem to me that Amigas and existing analogue video equipment could also
- be adapted to do some pretty useful things at the personal level.
-
- Any thoughts?
