What type of Film did video cameras for Hollywood use in the 1970's to make Hollywood movies?

Hollywood movies since the era of "talkies" have been shot on either 1 inch or 2 inch wide film strips. Known in the trade as "35mm" and "65mm". Silent movies and home movies from the 20s used 16mm or 1/2 inch wide film. then Kodak came out with its 8mm format for home movie use. 8mm is the same identical film as 16mm double perf but only exposed for half the width. the reel is flipped at the end and then the other side is exposed. 8mm is also 16 fps instead of 24 fps used for theatrical movies. thus it consumed a lot less film making it affordable for home use. after exposure, the double shot camera reel was developed, split down the center and spliced together to make a single 3.5 minute reel of 1/4 inch wide film with sprocket holes on one side only. The reels for 8mm film are the same as for 1/4 inch audio tape except they have a feature that prevents them from being mounted backwards on the projector.

when videotape came out with portable cameras for consumer use that pretty much ended the 8mm movie era. Kodak and other camera makers came out with Super8 which was a cartridge film system to try and compete. Compared to 8mm it offered improvements, like sound, higher frame rate (18 fps) slightly larger image size, battery power, and ease of handling, but the public preferred VHS that could be viewed on the TV set instead of requiring a projector and screen.

the majority of Hollywood movies are still shot on 65mm film. the film is often converted to 4k video for the purpose of editing and special effects creation and then regenerated back to film for theatrical use. it has only been very recently that CCD technology has improved to allow 4k video to be imaged directly by a digital camera, so that is the future of movie making as it matches the 4k video editing that has been done in Hollywood since the 1980s.. HDTV is 1k video for comparison.

there is a huge gap in quality between equipment made for the motion picture industry and home use. that is mostly because the big screen requires far more resolution than a TV set.

lare is right. The key comment he made, "the majority of Hollywood movies are still shot on 65mm film" is supported by staying through the credits... You will typically see "Panavision". Not directly to hard drives... still film, sent for processing and digitized. As for power supplies, "Car Batteries and power cords plugged to wall outlets" - not even close, especially when on location and there is not wall outlet. Try semi-truck mounted generators (more than one) like

And keep in mind, the cameras do not record audio... they record the moving images to film and later processing. Audio is recorded to a separate audio system, generally like a portable music studio, assuming that audio is even used... and don't forget lighting, monitors, trailers, camera cranes, motorized controls for various items, and a lot of other stuff that goes into a production...

I don't think "video tape" has ever been used in a "Hollywood movie" unless it was some sort of documentary... And even then, it would be supplementary to the film stock used for capturing the body of the production. The only recent one that comes to mind is the original "Paranormal Activity" was shot mostly on a Sony HDR-FX1 or HDR-FX1000, but that was also originally an indie production that was bought by a big studio after the project was done.
