31 Окт. 2014 г.Gopro прошивкаGoPro Studio will automatically download and install the new firmware onto your Hero camera. So go ahead, check your Hero camera now to see if you’ve got the latest software installed. Register your camera with the GoPro website and enter your device’s information as requested.Even the uncompressed mode of the new Blackmagic camera maps its 16bit linear output and only stores 12bit with a curve - this is not lossless, but you will not miss it either. As a result, most cameras map their sensor's 12, 14, 16bit linear image, to an 8, 10 or 12bit output with a log or gamma curve, exploiting that we humans will not notice. These GoPro “firmware” upgrades mean that the software of the actual Hero camera stays up-to-date with the latest features, so your camera stays cool and fresh. It should also be unplugged from your computer, and check that your camera battery is well charged. If you’ve got an outdated version, just follow any of the 3 methods above so you don’t miss out on the latest camera upgrades. Fortunately it turns out that linear is a very inefficient way of presenting light when humans are involved, as we see brightness changes logarithmicallya stop change is the same level of brightness change to us, whether it is from linear levels 1 to 2 or from 1024 to 2048. Once downloaded, save the file to your desktop, unzip the contents, and install GoPro Studio. After the first detectable level of light brings our ideal sensor from 0 to 1, a doubling of light goes from 1 to 2, and the next stop from 2 to 4, and so on to produce this series 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048 and 4095 of doubling brightness (to the point where the sensor clips.) An ideal 12bit sensor has a theoretical maximum of 12stops of dynamic range. Back in 2006, CineForm was very much involved with Silicon Imaging and the development of the SI2K camera, which was highly praised and generally confirmed to have around 11 stops of dynamic range - good enough to be used on the first digitally acquired feature (well, mostly digital) to win Oscar Cinematography and Best Picture awards. Making images look great out of the box is the right thing to do for all consumer cameras, and you get just that with HERO2 via HDMI to your TV. The dudes at GoPro are always working on ways to update and innovate the software of their Hero camera products. You also don’t want to be left out of the GoPro crowd by leaving your GoPro software stale and outdated. Before the firmware update you will notice there is the typical low-light artifacting present in smooth transitions and subtle tones, plus the overall dynamic range has increased substantially after the Protune update. Keep in mind that whether a certain option works for you or not will depend on the model type of your GoPro Hero camera. It was not just five years of sensor technology that made all the difference, it was using a log curve instead of contrast added to Rec709 with 2.2 gamma geek speak for calibrating cameras to make the default image look good on your TV.  You should also keep your camera software, or firmware, updated because it means that any bugs or software problems in older versions are fixed in your new camera update. So if an update option doesn’t work for you, or it’s too much trouble, then try one of the other upgrade options. I know this post has a clickbait sounding title, and for that I apologize, but I’m not writing this for click throughs or ad impressions. Lossless versus lossy is an argument you might have heard me present before, to the same conclusions.If we remained in linear, converting to 8bit from 12bit would truncate the bottom 4 stops of shadows detail, we will notice that. When it comes to editing and post-processing, some products are a reference in the market, but with so many new programs available, some FREE, the future may be different. Many professionals in the video editing industry have grown with a list of programs as their reference for quite some time, but a new generation of users is not bound to the same names. That's okay, because this is not nor is it intended to be a round-up of every single camera Sony has available. Step 4: If there is a software update available for your Hero camera, then the Home screen of your GoPro App will have a Software Update button showing. This gives a much more natural and softer look to the footage with a broadened range and flatter image color space. Or, maybe I should say I showed them how Alexa desaturates color with overexposure: once a hue passes a point at or near middle gray in brightness, its saturation locks and it only gets brighter. Several years ago, at an NAB focus group, I showed Sony the difference in how Alexa saturates color with overexposure vs. Smaller pixels often result in reduced dynamic range, yet so much has changed in so few years. Step 1: Make sure that your mobile device (such as your smartphone or tablet) has access to the internet and go download it at your local appstore. This is about the things that software can do now and guessing at what it will do in the very, very near future. So that may create possible synch issues over longer clips in your production workflow if combining your GoPro footage with other cameras.As far as the data rate and other tweaks to the sensor goes - this was the most notable difference I discovered.  |
