I had been looking for videos explaining the shutter for a while and, until finding this video, had not found anything very clear. this is So didatic....
"less technology" is actually euphemistic for "more simple." that's not to say there's no complexity, but at the same time... explaining how a digital projector functions to this precision would require a much deeper and broader explanation drawn from many more fields and disciplines. depending on how deeply you care about how digital devices work in general, this might include a dip into quantum mechanics, which are very relevant even in systems that rely mostly on classical mechanics. film projectors of that era could be explained intuitively, and understood intuitively. we are in an age where real-world phenomena have counterintuitive explanations, or explanations that are so technical you need education to understand them. it has a lot more to do with the technology itself than it does any way people explained it. i almost hate to say this, but if you can't understand modern explanations, it's probably your fault. this is potentially too blunt, but it is accurate.
@@korwl540I hear ya but I'm not sure if you we're directing that last part directly to me. If so, I didn't say that we couldn't understand modern explanations - just that they explained things better back then... This video was a high level view of how a Cinema Projector works, not technical explanations of how to build one. Never the less, I was just appreciating all the hard work that the creators of this video had to have put in to produce this film (without modern Computers, Software, Technology and ect). We tend to take videos like these for granted -- especially when all we have to do is fire up a PowerPoint with the click of a mouse.
When I was in my tender age I fascinated with films in theater....to understand the technology managed to see movie in oprator cabin.Thereafter , I used to collect the cut piece of the film thrown away behind the cinema hall. I made a card board projector at home and managed to enjoy Home theater using reflected sun light via mirror. I had to change the angle of the mirror with the moving sun.. As soon the sun light moved out, the show is over.

There is no any real cinemas today. They use digital now and that takes away the feeling of the real cinema and the moving pictures. I don´t go to cinemas anymore because of that.
Well said, I would like to represent this feeling as you look to a paper or vinyl artificial flower rather than a real garden one with all its swings, feels and aroma. Although i understand that a person grown up in digital age will hardly appreciate the old school 35 mm motion picture handling in Cinemas due to mindset difference "Analog vs Digital"
sound on film is achieved by sacrificing a little portion on the side of the film frame to fit a sound track (this is also probably where the term "soundtrack" came from) early 35mm films use an optical sound method. on the projector's sound reading area, there's a light bulb (usually called the exciter bulb) that shines light into a little slit. that slit only lets a small ribbon of light to pass through into a photoreceptor/light detecting cell. the sound track is basically going to let a specific amount of light to hit the light detecting cell by blocking the ribbon of light with dark areas. the size of dark areas vary with the volume and frequency of the sound intended to be reproduced, lower volumes have more dark areas and louder volumes have less dark areas. the dark areas also vary much more minutely to produce the specific frequency intended to be reproduced. higher frequencies have the areas vary more frequently and lower frequencies are less frequent. the light that's received by the light sensitive cell is converted into electrical currents, then these currents are greatly amplified and the amplified signal is then fed into the speaker, which reproduces the sound.
Do both reels move all the time? My projector, On fwd the left works on reverse the right works, But are they both supposed to move? I’m waiting for some old film reels in the mail to try my self
The takeup reel is powered and the feed reel is unpowered, with a little bit of drag to keep mild tension on the film. Usually the upper or front spindle holds the feed reel and the lower or rear spindle holds the takeup reel. If you have a projector with both spindle arms on top, and you are facing the right side of the projector where the controls and threading path are, the left reel will be the takeup reel when going forward. If your projector can play in reverse, the feed and takeup reels will reverse roles. When you have played the whole reel of film and let the tail run out the back of the projector (or better, stopped it before the tail leader and unthreaded the projector) you take the end of the film flapping loose on the left (rear) takeup reel, and thread it counter-clockwise around the hub on the right feed reel, putting an inch or so of the film in the notch in the hub for that purpose. Then hold your fingers _lightly_ on the rim of the full reel to provide a little braking, and put the projector into rewind. Keep you hand on or near the reel until the whole reel is rewound. If the film starts getting loose between the reels, apply a little pressure to the rear reel to tighten up the film a bit. If you don't do this and let the film rewind by itself, about half way through the reel the film will get loose, then usually drop off one reel or the other, tangle in the spindle supports, and stretch and break the film. Then you will have to cut a couple of feed of damaged film out of the middle of the show and splice the ends together.

It's worth off safe for movies in cinemas digital workes not safe for producing a movies buzzt final copy are nott safe without laws back this technology incinema worker's and makers swtt tha mind for this technique update this is best for life line for movies
i swear.... ...even with less technology back then, they explained things better...
Right?!

They were actually smarter back then.

We used to watch reel to reel movies at school when I was a kid. Our library also had a card catalog!!!!
It's a miracle for me all the time.
24 fps print projectors used a bowtie-shaped shutter to flash each frame twice to reduce flicker, so each image is on screen for 1/48th of a second
You know anybody that teaches people to run 35mm?
Seriously. You did fantastic work. Without technology at that time
Great explanatory video! Thanks for sharing!
why am I seeing this at 4am in the morning.. truly I'm single..😂😂
It's 10 minutes left before it's 3 am here and I'm just curious 🧐 that's why I'm watching it

This was best explanation I was always thinking how does it work it was for me like mysterious since I was Kid thank you for your video
I watched 10 other Videos from the last 2 years, but I understand the content first in this video

Strobe light warning!
This looks better than cinemas today
I love the look of old films :)

Great video! How do they sync audio for movies with dialogues?
seeing this in 2023 ❤
謝謝😊

0:43 they had the computer's cursor way back in this year? also is this video from the 1950s
It's just a normal arrow XD
Mükemmel eline emeğine sağlık usta teşekkür ederim
Nice information 👍🏼👍🏼👍🏼
Projecter mechanism
amazing. today now laserprojecter
Awesome verybrilliant..
This video explains how we see reality.

Anyone else tried to replicate this as a kid by placing a film negative of photos in front of a flash light
Hi can you tell me where you got this footage please? I would like to use it for a film!!

interesting, I've always wondered how films played
Gracias, nuevo suscriptor
Great work
I think this was seen from 1956, It’s my best guess.
Wow good 👍😍😊
2:01 Epilepsy warning!
Bende de sinema makinesi var.makine aksamı ile ilgili her türlü bilgi dikkatimi çekiyor.
i could not watch a movie that flips like that
Was it in the 50’s to 1966
I came to know about that shutter today.
When did the original video come out?
Around 1936.
A natureza é maravilhosa
So simple to make
My mind: *hey I'm making you search for this for some reason* this is very reel.
🤝🏻
Is that clip copyright free?
It's worth off safe for movies in cinemas digital workes not safe for producing a movies buzzt final copy are nott safe without laws back this technology incinema worker's and makers swtt tha mind for this technique update this is best for life line for movies
pretty cool
Wow
and then transistor came into existance.
What??? Acrobatic in a car *(laughs)*
Is it 60 fps?
Actually, films run at 24 fps, while youtube videos run at an average of 30-60 fps.
2:00 trigger warning
fascinating don't believe your eyes lol
