IIRC it could be used that way, but IIRC it wouldn't store an awful lot of video.

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.

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.
