Kernel Based modesetting in Linux

Posted on Sunday, April 20th, 2008

This is an interesting new feature coming soon to X.org and the Linux kernel – it’s basically moving a video card’s mode setting code (which makes the card change resolutions and so on) out of the user-mode video driver, and into the kernel. It probably doesn’t sound exciting, but it will lead to a much nicer user experience. For example, it helps to make the boot process more flicker free, and will make suspend and hibernation much more reliable.

It also makes switching from X to a virtual terminal much, much faster. There are some videos in the article demonstrating it, but since this is not planned for release until the end of the year, it is still fairly buggy and unreliable.

“Scarlet” 3K Camera revealed at NAB

Ever since RED Digital Cinema’s new professional pocket camera was mentioned at last years NAB tradeshow, there has been wild speculation circulating around almost every camera and video forum and website around. Most people were expecting an HD or 2K camera for around $5000. When you take a look at the specifications of other cameras around the same price on the market, such as Panasonic’s HVX-200 and the Sony PMW-EX1, you can see that they were asking for a lot.

But in true RED style, the announcement at 9:00am at this year’s NAB shocked us all. The resolution that this camera shoots is not HD. It’s not 2K. It’s 3K. To put that in perspective, that’s two and a half times bigger than full HD. It can shoot at up to 120 frames per second, or even as fast as 180fps for a burst of a few seconds. That means that a one second action, when played back at the regular 24 frames per second, becomes seven seconds of action. Another significant aspect of this camera is that it shoots REDCODE RAW. This is a compression scheme that is much more efficient than traditional codecs. This is similar to RAW on a digital SLR camera, but it’s compressed using wavelets. This codec gives you very close to uncompressed quality, but with a relativity low data rate.

Now, judging from other cameras on the market, a camera with these specifications would run into the hundreds of thousands of dollars. It would be surprising to see it on the lower side of $50,000. But RED is targeting a price of three thousand dollars. They did it with the RED ONE (a 4K resolution, $17, 500 camera now on the market that outstrips cameras like the Sony F950 – which retails for around $115,000 ), and I have complete faith that they can do it again.

Updated Blog

Posted on Sunday, April 6th, 2008

I have updated the blog to the newest version of Wordpress recently. In fact, I am running the bleeding edge version from the Subversion repository. So now when I need to upgrade, all that should be required is SSHing into the server and doing an svn up in the directory.

You’ll also notive that I moved the blog out of its own subdomain, and into the main site. I think its better this way, and makes it easier to keep all the images and media together.

And finally, I hope you like the new design! I have been working on the new site for a while now, and I think that it is much improved from the old version.
