Video camera? It's a movie projector. (5, Informative)

NixieBunny (859050) | more than 3 years ago | (#36211282)

There is a difference between movies and videos, and between projectors and cameras. Subtle, but it's there.

Re:Video camera? It's a movie projector. (0)

Anonymous Coward | more than 3 years ago | (#36211432)

Those differences only exist in English, which the summary writer plainly doesn't speak; to his mind, those terms are the same meaningless jibber as "parts Lego Technic parts".

Not since the advent of digital cameras; there's no projecting through negatives any more.

Re:Video camera? It's a movie projector. (1)

hedwards (940851) | more than 3 years ago | (#36213958)

That's not true. For quite a while you could get digital images converted to ones that could be put in a slide projector. Or onto regular 35mm film for creating normal prints from digital.

I think that has fallen by the wayside as other forms of printing have been advancing.

So if you converted an episode of Dharma and Greg to Super 8, it would become a movie if you played it on this device?

Re:Video camera? It's a movie projector. (1)

scottrocket (1065416) | more than 3 years ago | (#36211800)

I hold in my lap, as I type this a wind-up, Kodak Brownie Movie Camera Model 2, 8mm. It advertises that it make "marvelous full-color movies...outdoors, indoors". Given the times (late fifties), that is simply sensationalistic advertising (much like today?). I would call it a motion film camera, and the device in this story a motion film projector, or something along those lines.

Re:Video camera? It's a movie projector. (4, Informative)

Bing Tsher E (943915) | more than 3 years ago | (#36213052)

A Kodak Brownie is a regular 8mm camera. Not Super 8. Super 8 uses a film cassette, whereas regular 8mm used 16mm film with a sprocket on both sides. You turned the reel over to shoot the second side, then at the processor they split the film in half. For inexplicable reasons, Super 8 and Regular 8 film had different sprocket hole sizes, so they are incompatible formats.

Because Regular 8 film was regular 16mm stock and rolled on an open generic film reel, you can probably still get it. Super 8? Probably not.

Re:Video camera? It's a movie projector. (1)

scottrocket (1065416) | more than 3 years ago | (#36213872)

Right about the Super 8 (we also had a Super 8 - with a zoom button!). In fact, to avoid being pedantic I'm going to take back the last sentence of my previous post; if someone last week had asked me what this camera produced, I would've said "Home...movies". But I understood the AC's pov: I tend to think of movies as something commercial, not me running around the yard with a Frito Bandito mustache on my face.

Re:Video camera? It's a movie projector. (2)

MstrFool (127346) | more than 3 years ago | (#36212490)

Certainly. All that is needed to understand this is an understanding of the word 'Movie' and where it comes from. A Movie is not a big budget production that you pay to see, it is a series of still images projected in rapid succession to give the appearance of motion. Only quite recently has the terminology started to shift from 'Home Movies' to 'Home Video'. So yes, if you converted the video to super 8, it would in fact qualify as a movie. Though don't be surprised when kids these days aren't aware of the real meaning of the word and are confused by it. And get off my lawn...

Re:Video camera? It's a movie projector. (1)

hedwards (940851) | more than 3 years ago | (#36213970)

Sure why not, but unfortunately, it would still be Dharma and Greg.

Maybe not, but it'd no longer be "video".

Re:Video camera? It's a movie projector. (1)

sunderland56 (621843) | more than 3 years ago | (#36211896)

Especially since a camera must be light-tight; a projector, not so much. Legos fit snugly, but aren't light tight.

Re:Video camera? It's a movie projector. (1)

seifried (12921) | more than 3 years ago | (#36211968)

Just do a double layer with the joints of the two layers offset, you'd be down to pinpoints of light, which a third layer could solve. Or use tinfoil.

Re:Video camera? It's a movie projector. (1)

hedwards (940851) | more than 3 years ago | (#36213980)

I fondly recall the few times that a bunch of us got together and rented a movie projector and a few reals to watch. It was kind of a pain, but there's something about watching movies in a way that's roughly analogous to how they're viewed in a theater.

Re:Video camera? It's a movie projector. (1)

antdude (79039) | more than 3 years ago | (#36214198)

Funny, I complained about my local AMC movie theater not getting digital screen. They finally started getting and showing them last year or two. Now, my friends and I can finally stop going to far away theaters for better pictures.

I've got about 3hrs worth of 3min super 8 reels from the early 80's when my kids were toddlers, the projector still works. The grandkids are toddlers now but in a few years I think they will enjoy watching thier parent's childhood on grandpa's antique "video player".

There are no LEGOs! LEGO is the brand! The pieces are, well, pieces (or bricks, blocks or units or whatever). To say LEGOs is like saying Sheeps!

You try having kids and not calling them LEGOs. "Sammy! Clean up your LEGOs right this minute!"

Re:No, you neophyte! (1)

srodden (949473) | more than 3 years ago | (#36212020)

My parents used to call it "Lego" or "that mess" :-) Also we had a double-bed sheet that used to contain all my Lego. So cleaning up was a matter of grabbing 4 corners and lifting.

TBH I've always detested the idea of having kids but now it occurs to me that it would give me an excuse to play with Lego again, it's starting to have a bit more appeal!

Re:No, you neophyte! (1)

pookemon (909195) | more than 3 years ago | (#36214270)

Whatever happened to "This pig sty!"? It's pretty unlikely that the mess would only include "LEGOs".

Do you also tell them to "clean up your Sonys" or "put away your Mattels"?

I hope so, because the cardinal sin of the Geekhood is inconsistency.

When I was a kid, they still advertised 8mm films in the back of the seedier porn mags, usually with a cheap or free projector since nobody had them any more.

Off topic: apparently firefox doesn't think that "wank" is an English word, does this warrant a bug report?

Re:Off topic (0)

There are a bunch of words Firefox deems misspelled when they aren't. Happens in both languages I speak fluently. So yeah, I'd say it does warrant a bug report.

I see super 8 projectors (and others) at yard sales and flea markets all the time, and you could get one and the parts to illuminate it with LED as brightly as the original for dealextreme along with the used projector for less than the cost of the legos used to build this project.

Now, that doesn't make this any less cool, but it does make it very silly.

Other than the IMPORTANT PARTS... (0)

Anonymous Coward | more than 3 years ago | (#36211942)

...of a projector (like the lens, lamp and reels), this is "made" out of legos? That's like saying I made a car out of legos, though I ended up using a real engine, chassis and tires.

It's the film handling.... (4, Informative)

meekg (30651) | more than 3 years ago | (#36212838)

The important part is the film handler. Unlike a camera, which can run the film more or less continuously and use a fast shutter speed, a projector has to stop the film for most of the frame's duration, and then quickly accelerate it out of the way while only blocking the light for a very short duration, or else the movie would "smear". Of course it flickers, since this is Lego, but it doesn't smear, and that's quite a feat.

OK, but I still think that if I were to start a project like this and realize that I needed a lens, lamp and reels, the best way to get them would be to cannibalize another projector . . .

Was there ever an episode of UFO where something actually happens?

I've watched a bunch of them and it's always just one or two things happening, never a complete story. So unsatisfying given the work that went into the visual look of 1969's version of 1980.

I wonder why the shirts made of string never caught on.

I actually have a school's old library of 16mm educational films, & a few movies, so I'm biased towards 16mm but the larger 18mm reels are heavy, it might not even be physically possible on Legos without turntables, but then you need to have angled rollers for the threading to get the picture up-right & all that...it'd take up the whole table :P
