Teşekkürler.

[@PeriscopeFilm]

Thanks very, very much. Donations like this make it possible for us to save more rare and endangered films!

I love how these old-fashioned documentaries can explain complex topics with outstanding clarity and brevity.

[@silverhammer7779]

Great explanation of the basics of analog television. It's so easy these days either oversimplify or get so bogged down in details that you lose the audience in short time. Thank you for posting these old films and I always look forward to seeing them.

They got a few things wrong, though. For example, in the picture tube, the video signal is actually sent to the cathode. The control grid is used for blanking between lines and frames. In a colour tube, the control grids are where the colour signals get applied, but this film was only describing B&W TV. And this was very simplified. There was no mention of the studio and control room equipment, nor synchronization.

Future generations will value your restorations. Thank you so much for preserving these treasures.

Informative . 😊 I never knew that's how it worked.

[@Lurker1979]

Always wondered how a analog tv camera worked.

[@jsaurman]

I always wonder how these films get so beat up.

[@jaminova_1969]

One problem is degradation of the film media. They weren't designed for long-term storage and the mechanical process of film running through a projector causes scratches. Thankfully, we have archivists like Periscope Films trying to preserve as much of these old films and making digital copies!

I’m sure one day AI will get to the point where we can restore these completely back to 100% too.

Hi Jim, thanks for the comment and for being a sub. Films that we collect tend to have wear from use in classrooms and sometimes they have water damage or heat damage too! Then there is the issue with the color, which has often faded to red and has to be restored (see our video about rescuing a film collection to see how that is done). Sometimes film stocks also have shrunk from age, or have other problems like warp or what is known as "vinegar syndrome". We are dealing with many films now that are in the 100 year old category, or thereabouts.

Is that Bonnie and Clyde getting away?

[@NA-me6sh]

and they never mentioned how racist the technology is and apologized for it, etc... imagine that... Things sure have changed..

[@coloradostrong]

Do what?

Kids think us old farts (boomers) are stupid. They need more than an ESG degree to even start to understand this technology.
