For example, if MPEG-LA authorized Canon to use MPEG patents in consumer cameras only, and you bought one of those cameras and used it for commercial use, you are infringing the patent.

            If I were to encode the final video product in MPEG 2 or MPEG 4 and attempt to sell it then I would require a commercial license but not for using a camera.

                      So, let me get this straight.

                      You're saying that in an alternate universe where MPEG-LA and the Supreme Court said things that it did not say in this universe, it might be possible that you COULD be violating a patent by using a consumer camera for professional purposes, except not.

                      OK. Got it.

                      A video that grosses $500M does not require 5000X the number of cameras that a video grossing $100K requires. So how do you structure the license fees so that they are fair to everyone?

                      I guess now I can understand why patents are so completely worthless. Because of people who think like you.

                      I suppose you believe there should also be two tiers of super-sharp nanotech chef's knives. One for someone who cooks for their family and one for a master chef who owns a chain of restaurants.

                      If I invent the greatest oil paint ever, should I have two levels of licenses? One for somebody who paints still lifes in their family room and another for famous artists whose paintings sell for hundreds of thousands?

                      How 'bout this one? Think of all the patents involved with your desktop computer. There should be a divided market for personal computers. One for the kid who play WoW and another for his older brother who uses his computer to build a website which becomes the next Facebook. I mean, according to you, it's the only way to make licensing "fair".

                      I have no doubt that you're going to go down swinging with this idea, bws111. You'll aver to the end that of course there should be two price levels for golf clubs with patented technology. One for the Republican congressman who plays 160 rounds of golf per year with his 10 handicap and another for Tiger Woods.

                      But you would be completely insane. However, you have inadvertently made a great case for why our current patent system is completely useless.

                      So the answer to your question, "How do you structure license fees fairly?" is, "You do NOT structure license fees "fairly". You make your invention, you license it, you make some money and then invent something else. Your patent should not grant you fortunes for your descendants to the tenth generation. Your patent should not be a tax on everything. Your patent should not pass beyond whoever uses your invention to manufacture a product and sells it to someone. YOU GOT PAID BY THE MANUFACTURER FOR GOD'S SAKE, NOW SUCK IT UP AND INVENT SOMETHING ELSE. Don't be a baby and expect that the world owes you riches beyond measure just because you had one fucking idea, even if it happens to be a good idea.

          MPEG-LA basically claims certain financial rights over your project in exchange for the right to use the h.264 codec. This means that if you shoot a scene in h.264, but switch to something else to release on the web, they still have rights over you. If a contractor shoots in h.264 but sends you the video in a different format, they still claim rights over you. As far as I know, pretty much all HD cameras shoot in h.264.

          Some of this is definitely winnable in court, some isn't. But if you're an independent filmmaker, you don't have the money to go against one of the biggest legal groups in filmmaking.

Forget about a camera for cinema, with a sensor that size you're going to be struggling to get it not to look like a webcam video. Looking at the company that makes the actual camera element, though, it looks like they also sell a model with a more reasonably sized sensor, but it can only do 5fps. If they really want to pass this thing off as a motion picture camera, they need to find a solution that will give them a big sensor at a respectable frame rate. Hopefully that will be possible in the near future, because the rest of this project looks downright awesome.

Being able to record 12 minutes, you should be able to break up scenes into small enough segments to record all of it, so maybe with the right accessories maybe it can be a decent movie camera.

            Because when your lens is already wide open, that isn't really an option. For instance, with a 28/2.8 lens on my 20D (appreciably smaller than 35mm sensor, but still much larger than a compact digital) I can get somewhat shallow depth of field at f/2.8 at close range. If I mount it on a 5D Mark II, I can get that shallowness at a much longer range (still wide open), and when you get in really close it's just remarkably shallow.

              This results in the background looking more blurred despite having the same "depth of field".

    • Ouch, the sensor size is a limitation, you can get a new Canon camcorder with a sensor about that size for about $700 from a reputable shop. Sure, it won't have all the same features but that puts the whole thing into a bit of a perspective. The kit in question is above the base price of a 5D Mk. II, the saving grace of the Apertus is maybe access to less expensive lenses. I see some features that make it more useful in a production environment, but the sensor size is a major limitation.

      That's because in serious cinema (and still), there's no such concept as "the lens." It's "whichever lens is best for this particular lighting situation/distance/position," and you have a bag full of them that you swap out at will. While you can buy some SLR (and possibly cinema, I'm not really familiar with that world) cameras in a package deal with a lens, experienced users generally won't, unless the package just happens to include a lens that they want to have at a discount for buying it with the camera. Shipping a single lens with every camera would just be foolish, and turn away buyers who either already own or just don't want whatever particular lens you chose. Besides, at this point the entire camera has to be purchased piecemeal and assembled, so even if it were standard to include a lens with a camera purchase, it wouldn't exactly be the single issue standing between them and market dominance :/
      • Prosumer (I hate the word too) level cameras tend to be offered with or without a lens. Often there's two packages, a camera body+battery+remote, and a full kit with all that plus a lens, a bag, and a crappy cleaning kit. So it is slightly odd for something at this level (in small sensor land) to not be offered with a lens, but it's not really that big a deal.

        That made it sound like they were bad. The primary reason is that they're all generally bundled with an all-round lens and if you already have an SLR - which is pretty much a requirement for being called an advanced user - you already have it from your last camera. Unless they are changing lens system, which for a professional photographer is a huge decision not taken lightly. The best lenses are never bundled as far as I know, it's more of a "starter kit" for people that don't have any lenses already.

      because even amateur photographers have a few lenses

    • by vadim_t ( 324782 )

      Whatever lens you get with the camera isn't going to be a very good one. Good lenses can easily cost more than the camera itself, so of course that's not what they're going to bundle with it.

    This thing is trying to compete with the RED camera system and the 5D Mk. II. As others have said, the sensor is already behind. Everyone doing 2K on the cheap is using the 5D Mk. II as a video camera - it has a bigger, better sensor than anything anywhere in that price bracket, plus Canon's awesome lenses. The next step up is the RED system for 4K, which is just on fire right now because of its revolutionary modularity. This thing is pretty small potatoes compared to either of those two. It might be good for student filmmakers though. A school could buy a batch of them.

      I'd also like to add the T2i or the 7D. It's "Good Enough" for 1080p, continues to use great EOS lenses, does it cheaper than the 5D mk II and is $1k or less. As TFA points out, the cost of the system their pitching has a camera that STARTS at $2k and "More advanced sensor frontends could drastically increase this price". To me, Drastically increasing $2k puts you closer to a RED camera, and not quite so drastic, the 5D mk II, so the $2k camera is close to the same as the T2i or 7D and they cost quite a bit

      Well the not being hemmed in by the MPEG-LA's patent trolling would be one big advantage. "It's a shame your film has made some money or become famous, let's talk about damages."

      Being limited to the C or CS lenses seems like a pretty big thing when the 5D has a large range of interchangeable lenses, and apparently the Red One can use Nikon and Canon lenses with adapters and even have full electronic control of them. The people developing the Magic Lantern firmware [wikia.com] seem to be a fan of the 5D's larger sensor compared to the Red One, etc to the point where they are reverse engineering the camera to add some cinematic improvements to its firmware. That's pretty hard core.
      • Adapters from C/CS to any other mount are cheap. Going the reverse is expensive.
        • by AC-x ( 735297 )

          Sure you can get an adapter, but a 1/2.5" sensor has a crop factor of 6, so a 28mm lense becomes a (probably quite soft) 168mm lens and a 50mm lens because 300mm.

          • My understanding is that the sharpest part of the lens is in the center. So the crop factor actually reduces the vignetting effect of a poor lens.So a crappy lens might become usable when combined with a smaller sensor.. It's all a trade off anyway. Smaller sensor = lower cost to manufacture but lens can potentially be more expensive. You just need to find the sweet spot.

            Right now full frame seems like the way to go because it's easy to find cheap but good new and used lens. However, not too many cameras

        the Red One can use Nikon and Canon lenses

        You can do that, but in practice you almost never do it, except for some very special single shots. These are photo lenses which are not well suited for cinematography. The RED has a standard PL mount that takes any of the standard film camera lenses (Zeiss, Cooke, ...) from your local renting company.

        Maybe a better solution would be to find an existing camera that's A.Cheap B.Good enough for amateur cinema work (the target audience here) and C.Hackable.

        Then you go and produce a custom firmware that only records into non-patented formats.
        MPEG-LA comes knocking on your door, you can show them that the footage was NEVER encoded in MPEG.

          And that camera would be...? The whole point of the effort in this article and the Magic Lantern is that no such thing exists, particularly at HD quality. This effort is trying to put the hardware together from scratch and Magic Lantern is trying to hack existing hardware that has the features they want. However you should read up on the things they have to do to decode the Canon firmware just to have the chance to try to improve it. And that's for one of the cameras it's possible for.

    Or is this really the Elphel opensource/openhardware camera, and how Apertus hopes to add things around the edges. The camera is Elphel, as is the sensor and the software. The only thing that seems to be community-designed/built is the "rod" packaging, and maybe the battery rig.

  • That's the same kind of sensor you get in a small compact camera like an IXUS, you'll never get anywhere near cinematic quality with that because of noise, lack of dynamic range and most of all the small sensor gives a large depth of field, so no fancy depth of field effects. For comparison a 1/2.5" sensor is about the same size as Super8 film.

    For cinematic image quality (at least in terms of shallow depth of field) you need at least a 4/3rds size sensor (which is a bit larger than 16mm film), even better w
