IIRC it could be used that way, but IIRC it wouldn't store an awful lot of video.
I didn't realize the Avid stuff was as popular and
well-used as you guys are saying. ... Sounds like it was well used in professional
broadcast apps, also.
Avid was initially only professional and very expensive. The fully-loaded Avid/1 Media
Composer in 1989 had about 4 gigabytes of SCSI hard drive and 5 megabytes of RAM (in the
Mac) and cost nearly $80,000.00. IIRC that configuration could store something like 6
hours of 30 fps video with stereo CD-quality audio.
... but a TBC? Was that because you had to have video
timings exactly matching before you could successfully show bits from both at the same
time (ie.. in an A/B roll) or was it for a completely different purpose ?
A/B roll was one purpose. Another use was that some video sources (such as some sat
receivers) were not genlocked to the house standard, so we used TBCs to permit smooth
dissolves and switching between sat receivers and in-house sources which were genlocked.
We also got some out-of-house video (some church services shot by small churches come to
mind) that came in on VHS, and the VHS decks were not genlocked.
