How a Movie Projector Works

[alienhddna]

wile we wacth a movie some one up in the bofe working his ass off big time

[gandalf87264]

No, that is not how a projector works. That is what a projectionist has to do to make it work. How does a projector actually work? Geneva movement, perhaps? Light behind the film? Lenses to project the image onto the screen? That is HOW a projector works. I think you need to do a bit more research, Mr brain, then re make this video.

[mathieuemi666]

Don't forget the shutter which is a critial part! (Otherwise you would only see lot of colors on the screen...)

[AirForcedude5]

what self respecting theater still uses reel?

[hobojoeisme]

@AirForcedude5 all. 

[Tubetheweb]

how about a video showing a 3D movie projector. Please?

[Hepglon]

is that a toothbrush?

[therealimaxguy]

"non-sync" means any audio input that's not synced to the film. If there's no input to the nonsync, then there's no sound. Advertisement audio, CD music, etc would be considered "non-sync". I'm the Chief Projectionist at the Imax in Austin Tx, winner of the 2010 "Best IMAX Booth" award. Google "imaxguy" and on youtube as therealimaxguy. Search for "IMAX Projectionist".

40 years projection experience.

[bloominpen]

i need help rewinding the film on an 8mm sears projector...any help???

[bdeterman]

I love how when he mentions checking the sound, its set to "non-sync", meaning there would be no sound at all.

[Bish1013]

@bdeterman not true at all. our sound towers can be in non sync and theres sound

[bdeterman]

@Bish1013 Oh, ours never work that way. i assumed non-sync meant "off" or "ads"

[2muffinsinanoven]

BAHAHA "The projectionist cleans the projector before each showing" Yeah right! That's a weekly for the over acheivers at my theater!

[paulkaygmailcom]

they need to teach the local morons here to focus the picture before the movie starts

[domyaska]

thanks a lot!!!!!!!!!!!!!!!!!!!!!!!!!!!­!!!!!!

[pantyflash]

Like, miserable. No mention of pin register, anamorphic lens, lens throw, aspect ratio, shutter, or any other significant details. It's like saying that the way a car works is that you get in it, turn the key, and drive off. Very weak presentation. Way to go, babes!

[bluemark101]

stupid video. each cinema has a different setup and a different way of doing things. projectors vary, this particular one had equipment rediculously outdated. For example, modern film projectors had built in lenses and appeture plates which automatically switch we dont "mount" them before each show, hardly any mainstream cinema uses these anymore. And yes GarretBMXes, digital projection is already taking over properly with all cinemas set to be fully digital in the coming years.

[GarrettBMXes]

im sure those will be obsolete after a few years. digital projectors will take their place

[grodenbarg]

Ever seen one get stuck, and burn up the film? It happen really fast.and the movie is ruined, at best, at worst there is a fire..

[Speedster159]

WOW A BIG MACHINE!

[bobbedie]

wow now i finaly understand how it works, not thanks to this movies, cause this was just fking retarded

[dumle29]

know a days those projectors is replaced with digdital ones stack in groups of 4, 6 or more

[PictureHouseCinema]

This reminds me of a feature I saw once about how plastic is made. It showed comb being made, it didn't show what it said on the tin. Show us the workings of the mechanism.

[Discoo00o]

Sorry i just can't listen to your voice

[EETech]

Don't ever submit an article to How Stuff Works. I submitted an article on "How Motion Picture Projectors Work" and they rejected it saying that it was too "outdated", yet a month later, Marshall Brain published his own article containing the SAME "outdated" info mine had. When I called him out on it, his legal department e-mailed me. Unfortunately, you can't copyright ideas. He changed just enough of the wording so that I couldn't take legal action. Thanks Brain.

I hate threading the projecters! I have to become a pro at it...by this next weekend!

[PsycoMonkey42]

eh threading aint so bad after a while... once you know how to do everything it pretty much becomes second nature and you can thread a movie in no time.

[PhoenixTheGreat]

yeah, now I am better at it, but the tower of terror is a real b*tch

[northstar1950]

No mention of "persistence of vision" no mention of the maltese cross either, could have done a better job my self!!!

[starwars21]

Digital projection is really Digital "VIDEO" projection, folks! It's interesting how that word is conveniently not used in movie ads, etc. Why would you pay money to have the same type image that would get from your TV set at home?

Theaters that use digital VIDEO projection then should also allow you to bring in chips, beer, sofas, talk out loud, etc. You know..so you get the true VIDEO experience!

[RiseDarthVader]

Uh Digital projectors have a lot higher resolution then what you see at home. It has a higher resolution then Blu Ray believe it or not.

[ketogenesis]

ah, cool. then what about when there's a live PPV, such as wrestling? it's not on film O_o

[motox00]

he didnt teach much, and yes, we still use film

[Fader2003]

Digital Theater's are crap!!!,You mean to tell me that you would pay what it cost in this day and age to go to a movie theater and basically watch a movie that's based on a DVD or hard drive?? That's stupid as hell!!!!, DLP has no business in a movie theater at all

There is nothing in the world that can top the clearity and sharpness of 35mm,70mm Film "Film is the future of HD"

Dont Support Digital Theaters

[RiseDarthVader]

DVD resolution lines: 480

Blu Ray: 1080

Digital Cinema: 4000

It's alot better then what you will see at home. and 4k is approx the same resolution as 35mm but with alot better colour and not more flickering.

[StaticWrap]

Film has a resolution greater than digital cinema. It can be enlarged as much as you want without losing any detail. Same cannot be said for digital as artifacts are present on screen.

[live2blade]

haahh they still use film u knob head but that projector is really old the new ones u down even have to touch the film its self u just have to feed it in.

[lorisurfer666]

I STILL USE FILM AND IT LOOKS AWESOME- 35MM, 16MM, AND SUPER 8MM. hello 2008

[xzn88]

He's right. Film is still being used. All digital movie theatres are rare. Often times the preview ads are projected on a digital projector. But the actual movie is on film. Even IMAX is film.

[BmxProductions]

we actually do, im a projectionist at a movie theater and we do use film still to this day.

jackass

[Alexeuk]

Yeah, like 20 years ago! We don't use film anymore!!

[Born2killx]

Of course they still use film...
