- My impression is that parts of this exist today (frame grabbers,
- Quicktime, Toaster, etc.) but at the consumer level there is significant
- degradation of picture quality.

- This implies you want to view the result on a standard TV without noticing
- any artifacts or picture degradation beyond VHS quality. So far any
- computer video I've seen looks pretty bad even in tiny windows. I would
- not want to see it on a 27" TV. (especially at <60 fields/sec!)
-
- We should not underestimate the amazing capacity analog signals have for
- carrying the enormous amount of information needed to satisfy the human
- visual system.
-
- What we really need are computer assisted analog devices at the consumer
- level. There is no technical reason why SMPTE timecode based computer
- controlled VCRs and effects generators are not readily available. What's
- preventing this? It is probably the same forces which caused Pioneer to
- REMOVE the computer control jacks from their consumer laser disc players.
-
- As for the request, what's wrong with VCR to VCR editing with a Toaster
- for effects and Federal Express for transmission.
