Exploring death through the isolation of VR
I'm sitting on a field of tall, red grass staring straight ahead at a lone tree. Its leaves match the crimson landscape that stretches out before me. In the distance, a rusty orange forest fades into the background. There's a gentle rustling of leaves, occasionally interrupted by the faint chirping of a bird, that forces me to breathe slower.
First Canon 7D RAW video shown courtesy of Magic Lantern
If you've been lustfully eying the latest DSLR models, you want to give your trusty Canon 7D another look. The popular, but aging semi-pro model has been given the RAW video treatment from Magic Lantern, and the first samples have now been posted (after the break). Maximum resolution still falls short of the much newer 5D Mark III's full HD at 1,736 x 1,156, but otherwise, the images are improved in every way. The video has a full 14-bit color spectrum, for starters, is completely free of compression noise and has much less (though still some) moire and aliasing. So far, video can only be captured in 2 second bursts, but we saw similar limitations on early Magic Lantern builds for the 5D Mark III, as well -- meaning the 7D may finally live up to its beast-like video potential.
Magic Lantern gives 14 stops of DR to Canon 5D Mark III with dual ISO recording
Magic Lantern's brought some miraculous features to Canon EOS DSLRs lately, including RAW video recording on the 5D Mark III, and video recording, period, to the 50D. Its latest feat is no less amazing, even for jaded DSLR shooters. By exploiting unused dual ISO amplifiers on a sensor chip in the Canon 5D Mark III and 7D, new firmware allows you to record lighter parts of a scene at ISO 100 and darker portions at ISO 1600. It works with RAW video and stills on the 5D III and RAW stills only on the 7D, with both requiring post-processing after capture. That bit of creative coding increases the dynamic range of both cameras to around 14, though not without some drawbacks. Namely, the 7D implementation is buggy for now, you'll lose some resolution while gaining aliasing in shadows and highlights, and won't be able to check critical focus by zooming in. Still, the organization has a track record of quickly improving new features -- so, if you've got the guts to risk voiding your warranty, hit the source.
University of Toronto student tech shoots HDR video in real-time (eyes-on)
Sure, you love the HDR pictures coming from your point-and-shoot, smartphone or perhaps even your Glass. But what if you want to Hangout in HDR? An enterprising grad student from the University of Toronto named Tao Ai -- under the tutelage of Steve Mann -- has figured out how to shoot HDR video in real-time. The trick was accomplished using a Canon 60D DSLR running Magic Lantern firmware and an off-the-shelf video processing board with a field programmable gate array (FPGA), plus some custom software to process the video coming from the camera. It works by taking in a raw feed of alternatively under and over exposed video and storing it in a buffer, then processing the video on its way to a screen. What results is the virtually latency-free 480p resolution HDR video at 60 frames per second seen in our video after the break. When we asked whether higher resolution and faster frame rate output is possible, we were told that the current limitations are the speed of the imaging chip on the board and the bandwidth of the memory buffer. The setup we saw utilized a relatively cheap $200 Digilent board with a Xilinx chip, but a 1080p version is in the works using a more expensive board and DDR3 memory. Of course, the current system is for research purposes only, but the technology can be applied in consumer devices -- as long as they have an FPGA and offer open source firmware. So, should the OEM's get with the program, we can have HDR moving pictures to go with our stationary ones.
Canon 50D gains video recording through Magic Lantern RAW hack
It may be time to dust off that Canon 50D you purchased back in 2008. The folks behind the Magic Lantern firmware add-on have pulled yet another rabbit out the proverbial hat (or is it lantern?) by enabling RAW video recording on the APS-C-based DSLR. What's even more impressive is that the 50D lacks video support out of the box, so this new-found functionality is truly magical. This hack comes hot on the heels of the Magic Lantern team coaxing the Canon 5D Mark II / III into capturing 24 fps RAW video. With the firmware add-on installed, the 50D is capable of shooting video up to 1592 x 1062 pixels at 30 fps. There are some caveats, though. First, there's no audio recording since the camera lacks a microphone input and associated electronics. Second, capturing RAW video requires fast CF cards (at least UDMA 6). Third, we now fully expect to see the 50D skyrocket in value on the used market. Hit the break for a few sample videos.
Canon 5D Mark III now captures 24 fps RAW video thanks to Magic Lantern firmware add-on (update: Mark II also)
It's no secret that Canon's 5D Mark III is the go-to DSLR for videographers the world over, but things are about to become a whole lot more interesting. The people behind Magic Lantern have successfully coaxed the 5D Mark III into shooting 24 fps RAW video at resolutions up to 1,920 x 820 pixels using 1000x speed cards. If you're not familiar with Magic Lantern, it's an open source firmware add-on that brings additional functionality to Canon EOS cameras. The ability to capture RAW video at 24 fps improves dynamic range and resolution -- it also provides extra flexibility during post-production. According to the team at Magic Lantern, more work is required before the feature is ready to be deployed. So until then, you're invited to follow the via link below and watch the RAW vs. H.264 videos after the break, or if you're feeling brave, check the source for download locations. Update: We just received news from Magic Lantern that Canon's Mark II is now also a go for 24 fps with the new firmware. Nic from the development team said "After some further testing it is clear the older, cheaper Mark II should be able to record at least resolutions of 1880x840 in full-frame mode (with line skipping)."
Magic Lantern EOS 5D Mark II firmware tweaks video mode, adds more manual controls
It's hacky and requires some fiddling, but EOS 5D Mark II owners interested in maxing out their video abilities will want to check out the new Magic Lantern firmware developed by Trammell Hudson. The new code adds a tons of features, including on-screen audio meters, audio and video gain control with the option to disable the auto settings, zebra stripe masking of overexposed areas, and on-screen aspect ratio overlays -- and what's more, it's billed as an "open platform," so there should be many more plugins and tweaks forthcoming. Caveats apply with this early release, though: you need to reload the firmware if the camera so much as goes to sleep, and battery drain appears to be an unresolved issue. Still, we're certain these problems will be fixed over time, since we're guessing there's gonna be tons of interest in this -- if Canon would just throw us some autofocus in addition to those new manual exposure controls, we'd be all set.[Via Wired]
