Rodriguez uses Linux to Edge out ILM
An anonymous reader writes "A Linux device helped legendary independent filmmaker Robert Rodriguez (El Mariachi, Desperado, Spy Kids, Once Upon a Time in Mexico, and others) win the race with ILM (Industrial Light and Magic) to create the first movie ever to use a digital format supporting full-bandwidth RGB. Rodriguez's Sin City, which opens April 1, was shot in Dual Link, or "4:4:4" format, and transferred between tapes and hard drives using SpectSoft's Linux-based RaveHD DDR (digital disk recorder)."
I would bet that a lot of the digital effects used in this film were rendered and perhaps even designed with Linux. If they were done with Windows they would have used a blue screen.
Rodriguez's Sin City,
Actually, its Frank Miller's Sin City. IMHO the writer is more important than the director.
"For Great Justice."
"It's really the same as 1:1:1," explains Howard. "It just means 'take RGB, break it up, send part of it down one wire, and part down the other wire.'"
The compromises in traditional Y'CbCr formats were designed to minimize perceptual loss, keying on the human eye's varying sensitivity to luminescence at various color frequencies. We are most sensitive to brightness in green light, less so in reds, and least with blue. This explains why studios often shoot against a "greenscreen" -- Y'CbCr has most information about green, so it's the easiest color for a software program to identify and replace.

I've had unreasonably high hopes for "Sin City" ever since I watched that fabulous trailer. But it's not like graphic novels-turned-movies have impeccable track records on the big screen, so imagine my concern going into this.

For lack of a more eloquent explanation, "Sin City" freaking rules.
Remember the first time you saw "Pulp Fiction"? You were unnerved and at times downright repelled, but you admitted that it was the freshest, most original thing to be put into a theater since... ever, and you couldn't wait to talk about how amazing it was with everyone you knew? "Sin City" is kind of like that.

1. Is "Sin City" a family movie?
- Heavens no. It's incredibly graphic and gruesome. I know YOU'RE into that, but don't bring the kids.
6. Does the all-star cast detract from the story at all?
- Refreshingly, no. No one character is the main star, it's more like a bunch of supporting roles. Great supporting roles. These actors are stoked.
8. Are we talking CG animation or live action?
- Almost all the live action was done with green screens and props, then the magic was painted in later. It's amazing.
10. I was pleased to see lots of hot chicks in the trailer. Can I expect more of that?
- You sure can, my friend! But they'll also chop your head off. Literally.
have you read the article?
"But what about "4:4:4 Y'CbCr"?!
Y'CbCr, also known as YUV, is the color space used by film editing equipment. Y represents luminance, while Cb and Cr are color difference signals.
Consumer DV (digital video) cameras typically use a 4:1:1 Y'CbCr format, in which luminance is sampled for each pixel, while Cb and Cr are sampled at every fourth pixel. SD (standard definition) cameras use a 4:2:2 format. HD cameras can use 4:2:2, or a 4:2:0 format based on "spatial" samples of 2x2-pixel squares. Dual Link, however, uses a 4:4:4 technique."
Deliriant isti Americani.
yes, because ILM was much more than just a render farm. Teams of talented artists, model makers and engineers have kept them relevent.
Incidentally, another distinction earned by Rodriguez during the making of Sin City, is that he joined George Lucas and others who have been kicked out of the Director's Guild. Rodriguez's offense, Howard says, was working with a co-director -- Sin City comic book creator Frank Miller -- who doesn't belong to the Guild.
I know it's slightly offtopic, but Robert Rodriguez wasn't kicked out of the DGA. He quit because they wouldn't allow him to credit Frank Miller as a co-director.
Kudos to him, I say.
I know you guys have to frame everything in terms of "LINUX WINS!" but you know what? It's not a race. Nobody was sitting around a table going, "I wanna be the first to make a feature with 4:4:4 dual-link RGB!" In fact, just the opposite: Everybody was sitting around going, "Let somebody else try 4:4:4 HD video. I don't want to take a chance on it with millions of dollars of somebody else's money."
Besides that, this whole thing is completely wrong. We've been using 4:4:4 for years in film production with a device called a "datacine." Go out and shoot 35mm film, which by the way has more color sensitivity than any video camera on the market, then run it through a device that scans each frame at high bit depth and high resolution in (you guessed it) 4:4:4 RGB.
Seriously, these machines have been around for more than a decade. RGB production is nothing new. You guys are making it sound like it's revolutionary, or worse, like it COULDN'T BE DONE WITHOUT LINUX. Inferno has done 4:4:4 since the mid-90s, and that runs on SGI gear.
