ABC TV Videotape room tour and edit demo [720p60] 

Thanks to Bobby Springer for bring this and a couple of longer cuts to us featuring Robert H Springer, Head of Videotape at ABC TV in the US in the late-1950's doing a tour of the videotape room with it's racks of video equipment and rows of early Ampex VT machines. Interesting to note the presence of Ray Dolby, famous for his audio noise reduction system, and key team member in the development of the Quadruplex 2 inch videotape system at Ampex that was the first commercially used VTR, and a format that lasted into the early 1980's. (I managed to use a colour Ampex 2" Quad AVR-2 machine when I was training as a sound engineer at the BBC - quite chuffed there).
This is a short 7 minute extract from the 36 minute tour which was shot on electronic cameras and recorded on videotape for student at UCLA to watch.
The videotape of this tour for UCLA students has not survived it would seem, but a 24fps kinescope (or telerecording as we call them here in the UK) was made. I've re-rendered this at both 48 progressive frames per second and 60 progressive frames per second for each of the edit lengths put up on RU-vid by Bobby Springer, and have found that the 60fps versions look more fluid and LIVE!
Enjoy. If you want me to upload the full 36 minute tour of the videotape room in 720p60, ask in the comments space below.
