Video Toaster 4000 Specifications
NTSC only non-linear editing system
broadcast quality, tapeless nonlinear editing system for the Video Toaster and Video Toaster 4000

requirements
Video Toaster with v4.1 software
a SCSI 2 drive for Lightwave recording
three SCSI 2 drives for A/B roll editing – two for video, one for audio
input from video tapes must be time base corrected

More Specifications
compresses and plays back video in realtime
true broadcast quality – 60 fields per second, full overscan 752×480
internally works with D2 data – no D2 / composite transcoding
proprietary coporession method: Video Toaster Adaptive Statistical Coding (VTASC):
relies on limiting the video signal (i.e. dropping to Beta SP quality) instead of lowering picture quality as do JPEG, MPEG, WaveLet
no visible pixelization, artifacts show as video “noise” instead of jpeg “blockiness”
by using faster drives, lossless D2 quality can be achieved
three SCSI buses (two for video, one for audio), each bus can handle 7 SCSI drives (21 total)
two serial ports to control serial-capable VTRs
the SCSI and serial ports can be routed outside of the computer with the so called Octopus cable
