Yeah, well, it's easy to get confused when you're looking at digital
video and thinking video must be as old as film simply because both
have been part of your ordinary life experience since birth.  And the
frame rate for video is pretty much fixed at either "drop frame"  (30
fps) or "non-drop frame" (29.97 fps).  Video "shutter speed" can be
altered on professional cameras for high-speed frame capture.
Sometimes you see computer monitors in video than don't have the "roll"
because the camera operator has synced the shutter speed to the video
display rate.

This clip was shot on film.  Video simply doesn't have the dynamic
range to produce the level of detail that's apparent in those low
lighting conditions and to the trained eye (mine) it has the
unmistakable, unduplicatable look of film.  Today film is commonly
dumped to digital, edited and effects added, then dumped back to film
for distribution.

The audio has oh so obviously been dubbed over.  Ignoring the fact that
the acceleration is a bad mismatch for the audio... at the very least
the front of the car to which the camera was affixed would move up and
down just a tad during the hard acceleration, shifts and braking
supposedly occuring.  The camera is obviously gyroscopically stabilized
but stabilization wasn't then what it is now, or anywhere close.

I'm sure it was plenty good enough to fool audiences in the '70's,
especially in a theater environment with the audio blasting.  It seems
audiences are still quite willing to suspend belief of what their eye
sees and believe what their ears hear in the 21st century.
