GPL Firmware For Canon 5D Mk II Adds Features For Filmmakers
tramm writes "I've released an extension for the Canon 5D Mark II DSLR's video mode to enable functions that are useful for independent film makers. While the camera produces a great movie out of the box, the audio is a severely limited. My code adds features that should have been in the software, like on-screen stereo audio meters, live audio monitoring, reduced audio noise and crop marks for different formats. An introductory video shows the new features in use and an audio evaluation compares it to the stock firmware with very good results. It's similar to the incredibly flexible CHDK software for Canon's point-and-shoot cameras, but targeted at the film makers using the 5D. The Magic Lantern firmware is GPLed and new features will be written to make the camera even more useful on set. There is a wiki for documentation and development."
Is this post about technology or someone bragging about accomplishments...?

Sounds complicated and admittedly, I know very little about this, but congrats anyway.
Laughter is the best medicine, except if you have a broken rib.
Why would anyone use this camera to make an independent film? It's an SLR still camera that only has a video mode thrown in as an afterthought (meant for taking a few minutes of video). You could get a real HD video camera, much better suited for filmmaking, for the same price.

Wow, sounds like you've added some great functionality. Interesting read.
I have a T1i- the little brother to the 5d Mark II. Any thought on firmware for this model?
Aside from not being full frame, it also only does 1080P video @ 20FPS... I understand that it *can* do 30 but Canon crippled it as to not encroach on the 5D market. Has anyone seen any "updated" firmware to crank the frames for the T1i? :)
Magic Lantern? Do you open sores fucktards know how to name something so it has any relevance at all to your software?
This GPL'd firmware sounds cool and the 5D2 is a cool camera. However, people who are interested in getting one solely for video should also look at the Panasonic GH1: it has stepless aperture control (with the right lens) and is in general made for video, unlike the 5D2 which has half-afterthought video.
The reason I mention the GH1 is that it's really the first digital system camera that's 1) Made for video 2) Costs below 1500-2000 euros. It would be nice if the firmware hack people could do it for some other brands than Canon too though...
The models won't matter soon though: all of this points to high quality video soon being available from lots of companies for anyone with 1000 euros to spend. Essentially, anyone with a decent income can soon only blame themselves for their video footage sucking.
Two words: very impressive!
Now just give us 24 fps and maybe externally controllable aperture and focus (ability to focus the lens to specific distance).
If those are possible, if necessary, I'll bow towards your generic direction several times per day. ;)
That, and a reasonable contribution to your paypal account.
This wasn't automatically picked up by slashdot's "related story" thingy:

Why not?
It's possible, they can do it, so why not do it? I, for one, welcome custom camera firmwares. The more the merrier - I know I had a reply on Slashdot before where I asked if there was a programmable camera; lo and behold, there is.. and there's some very fun projects coming out of it. Why let the camera maker dictate what you can do with the camera, when you know that it is physically capable of so much more? E.g. why limit exposure times to 2 seconds, when there's no physical reason you couldn't keep the shutter open for an hour? )
As for HD.. an HD camera, 1080i/p, is 1920x1080.
The 5D Mark 2 is 5616x3744. That's larger than 4K cinema. Let me put it differently.. that's larger than practically every single movie you see on 'the big screen' today (which are often finished at 2K, or post-effected at 2K and upressed to 3K).
Sure, a consumer might not exactly -need- 4K. I'm not so sure they need HD - non-'HD' youtube resolution seems to be just fine for most people. But, again, it's possible.. so why not?
RED, at one point, decided that movies could he shot all-digital and made their behemoths based around fairly expensive sensors... now Canon, Nikon, Kodak, SONY, etc. are realizing that their sensors are getting fast enough to do movies as well.. and they're taking full advantage of it.

As awesome as these hacks for the Canon cameras are, as a 40d owner I'm feeling a bit left out. I have the CHDK firmware for my S3IS which is awesome; multiple exposure bracketing, RAW support, and scripts galore. And now extra movie support functions for the 5d. There was a guy a while back who hacked the 40d to shoot video, but he ended up getting hired by Nikon and couldn't release his code. Anyone know of any efforts to hack these cameras as well?
Shameless plug for my photos on Flickr
According to the wikipedia page:
The 21 megapixel sensor is downsampled to HD resolution by only using every third line and 4:2:0 chroma subsampling[8], leading to concern about Moiré patterns in recorded video
Does the software address this? Or is it a non-issue?
I never undestood why don't manafactures already have all these features.
It's easier for them than for anyone else to develop this kind of things..
Hi y'all If you're interested in the 5D mk ii, you should check out my blog and wiki - http://planet5d.com/ - the best 5D information on the planet! We have had several posts on this story since it was 'announced' several weeks ago (yesterday's formal announcement was the first 'release' of the software to the public - but we've been covering it before that).
Can anyone explain to me what exactly is the fascination with QuickTime MOV format?
Kodak's cameras record video in MOV. Apparently Canon's cameras also record video in MOV.
It's a PITA because Apple is so stingy about licensing the codecs for its QuickTime formats (no, I don't want to buy QuickTime Pro). It makes it a major inconvenience if I want to actually edit the clips. So, why do I have to put up with this?
Sorry if this seems like a rant. If there's some reason why MOV seems to be favoured, I'm honestly curious as to what it is.

With Canon, we can.
Here be signatures
Not only does Canon let the consumer play around with the firmware they encourage it, as far as CHDK goes there are tons of parameters if its not working the way you want it to its your fault. I have taken shots of lightning where the motion detection script responds in 110ms. To take advantage of RAW (CRW file format) you have to be a borderline pro photographer and know how to convert them to DNG, preserving the 10 bit color, and then I use RawTherapee and possibly GIMP.
I own the 5D Mark II and I love it, especially since Canon recently released the firmware to enable ISO, Aperature and Shutter Speed control in video mode. I work on indie film and professional video and I can tell you that even though this isn't a "video" camera, the full-frame sensor and the Canon line of lenses, especially the high-end primes, are a wonderful combination. Such shallow depth of field, such great color reproduction, and great low light sensitivity.
Most prosumer / consumer HD cameras can't touch the sensor and lens combo that this camera does, unless you get above 10K$ for your camera. Naturally, in indie film we want to get the best bang for the money, so this camera has been a godsend. A lot of companies like Redrock and Zacuto are now selling full rail systems with matte boxes and follow focus equipment for this and other DSLR's enabling a DP to utilize a DSLR like a traditional video or film motion picture camera.
One of the biggest issues with this third-party firmware is it has to be reinstalled every time you power down and power up the camera. I hope Canon sees what the community is doing and adds these features directly or at least supports the development of 3rd party firmware. We're still missing 24/25P, and a real Zebra function would be incredible.
Abuse my rationalization of rhetoric as either metaphor or monotomy.
You can also make some videos with stills.

(do get the HD videos, they're MUCH better)
I recall the slashdot story saying that many of us can't see the Milky Way at night, but that's not true - we can see it on Youtube.
And we can even see beautiful sunrises from our basements ;).
FWIW those camera sensors and lenses are better then my eyes in terms of quality of picture.
The rolling shutter is no where near as slow as 1 line/frame. It scans the entire frame at about 120 Hz, which is still slow enough to show some of the "jello" effect. But the entire frame is still progressive scan.
I seem to have stumbled into the Slashdot Classified Ads section. And I didn't even know that Slashdot had a Classified Ads section.
But given that its GPL code I will mute my criticism that this post is put up by the author, and not a more neutral review site.
"It's the height of ridiculousness to say for those 9 lines you get hundreds of millions."
The greater depth of field of the GH1 is by no means a disadvantage. The idea that a camera like the GH1 is somehow crippled because it's DOF is wider is just an internets camera measurebator myth. The lenses needed for a sensor of the size of the GH1's are large enough to produce perfectly fine background blur, and you'll get more of your subject in focus thanks to the greater DOF. The larger sensor cameras shallower depth of field is in nearly every case a disadvantage, though one that they make up for thanks to having much larger sensors (and thus allowing you stop down the aperture and crank up the ISO).
These two posts at The Online Photographer make for instructive reading:
Are you adequate?
And companies won't make products like that unless they're willing to abandon their business strategy and relinquish control. A company makes products for the company's sake. Its the same thing that governs the product's features (implemented, locked in and otherwise). If a company was willing to create a product for the product's sake, they would have no control of it because it would be so many different things to so many different users. How many companies do you know that are willing to take that risk? That's open source's niche and that's what makes it so amazing. Its a meritocracy.
Find a job you like and you will never work a day in your life.
Will the Panasonic GH1 run free software firmware like the Canon 5D Mark II apparently can? If not, I don't see the advantage. The story says that these hackers added features Canon didn't; that's added value to me. That makes me want to consider a Canon 5D Mark II for a camera purchase. Thanks to their work, I am not dependent on Canon in the way I am dependent on a proprietor for other hardware which lacks free software firmware. Even if these hackers stop developing that firmware anyone willing to learn can pick up the job, or I can hire others to work on my behalf. And because the software isn't just free but copylefted under the GPL, I stand a better chance of benefitting from any distributed/conveyed derivative work based on this firmware. All of this future-proofing exists because of the freedoms of free software.

The DOF control with a large sensor is simply amazing. To get similar quality of video with such DOF control you need a 50000$ cam
