To learn more about the UAD codec, please see the <strong> [[UAD CODEC WHITE PAPER]].</strong>\n<br><br>\n==Quick Start==\n<br>\n====System Requirements====\n* Windows 10 or macOS\n* Adobe Premiere Pro CC 2015 or newer\n* Intel/AMD 64-bit CPU ''(Native Apple M1 support in progress)''\n* Graphics card with support for OpenCL 1.2 or newer\n<br>\n====Installation====\nUse the following installer for your platform to install the UAD codec plugin:<br>\nWindows: [http://www.octopuscinema.com/downloads/OCTOPUS-UAD-Windows-Installer.msi OCTOPUS-UAD-Windows-Installer.msi]<br>\nmacOS: [http://www.octopuscinema.com/downloads/OCTOPUS-UAD-macOS-Installer.pkg OCTOPUS-UAD-macOS-Installer.pkg]\n\nThe installer will automatically detect the correct location to install the plugin for Adobe Premiere Pro. Please do not change the installation directory unless you know what you are doing.\n<br>\n<br>\n====Sample .UAD Files====\nThe following UAD-RAW sample files can be downloaded for evaluation of the UAD codec and plugin:\n<br>\n[[File:uad-thumbnail1.jpg|left|frameless|class=rounded-corners|UAD Thumbnail]]\n\n<span style=\"white-space: nowrap;\">UAD-RAW 2:1<br>\n7680 x 3200<br>\n24 FPS<br><br>\n[https://drive.google.com/uc?export=download&id=1M73rkrN1vRVS3wyNgxFINwxq8_6UJd-K DONWNLOAD .UAD - 5.2GB]</span>\n<br><br>\nFind more UAD sample files in the [http://octopuscinema.com/uad-sample-files UAD Sample Files Gallery]\n<br>\n<br>\n==Usage==\nWorking with the .UAD files in Adobe Premiere Pro is the same as working with any other video format. Simply drag .UAD files into projects and timelines, or navigate responsive .UAD thumbnails with the ''Media Browser''.\n<br>\n<br>\n====RAW Image Controls====\n[[File:uad-raw-plugin-usage.png|thumb|Accessing UAD-RAW Source Settings in Premiere Pro]]\nWhen working with UAD-RAW or any raw format, the image needs ''developing'' to look normal. Raw formats can expose control over the developing process. These controls typically include ''white balance/tint'' and ''exposure'' but can also feature more advanced and creative options. The UAD plugin exposes as much as possible while remaining straight forward to use.\n\nTo access the UAD-RAW image controls, select the clip in the timeline and then navigate to the ''Effect Controls'' window. Inside the ''Effect Controls'' window, activate the ''Source'' tab to show the source settings for the clip. This will be titled <span style=\"white-space: nowrap;\">''Source * CLIPNAME.uad''</span>."

                        "*": "==Introduction==\n\nUAD (Uncompressed Adaptive Downsampling) is a new open source and radically different approach to image acquisition. UAD does not ''compress'' data, but rather it dynamically alters the data frequency in the spatial domain - in the context of image data, this means dynamically altering resolution within a single image.\n\nAs CMOS image sensors increase in resolution, the bandwidth and storage requirements race upwards. When an image sensor increases in physical size, however, the optical behaviour creates a larger disparity between what is in and out of focus. At the extreme end, the large imaging area of a medium format camera creates\nimages with typically only a small percentage of in-focus pixels. Despite this, medium format CMOS sensors are usually much higher resolution than their smaller counterparts.\n\nUAD exploits the notion that only some areas of an image or frame will benefit from an image sensor's full resolving power. Instead of ''compressing'' images by looking for entropy to predict image data, UAD simply reduces the resolution of lower precedence areas.\n\n\n====Benefits====\nBenefits of UAD's encoding method include:\n\n* '''Uncompressed quality''' Colour accuracy and fidelity is not affected by downsampling, higher reduction ratios only ever trade off resolution.\n* '''GPU efficiency''' Resizing image data can be done on GPUs extremely fast. 8K UAD can be encoded at faster than real-time (30fps+) even on mobile class hardware with integrated GPUs.\n* '''Freedom from compression patent infringement''' UAD's lack of ''compression'' or ''entropy'' approach means it does not use any compression algorithms which could be considered prior art.\n* '''Multi-resolution decoding''' Decoding can be performed directly to lower resolutions allowing for manageable real-time performance on low spec hardware.\n\n\n====Supported Formats====\nCodec development is on-going with image format support as follows:\n\n* 12-bit log encoded CFA Bayer RAW (Fully implemented)\n* 12-bit log encoded monochrome (Planned)\n* 12-bit YUV video (Planned)\n\n\n====Data Rate====\nThe codec is designed for quality and throughput at the expense of size and recommends the following size reduction ratios for high fidelity capture:\n\n* 4:1\n* 3:1\n* 2:1\n\n<br>\n==Why Open Source==\nUAD is a true open source codec and the only truly open source RAW video codec. The UAD code base is publicly accessible on [https://github.com/octopuscinema/uad GitHub].\nThe UAD repository is licenced with the permissive [https://www.apache.org/licenses/LICENSE-2.0 Apache 2.0 License]. \n\n* '''Future proof''' Open source software can be ported to any platform by anyone and can be updated to work with new hardware and environments as they emerge.\n* '''Work smarter''' Avoiding the proprietary black-box approach promotes learning and the understanding of how tools work. The entire raw developing process for example lives in [https://github.com/octopuscinema/uad/blob/main/octopus-uad/Codec/CL/RawProcess.cl RawProcess.cl]. Even with no programming knowledge, one could see how parameters like exposure, contrast and saturation are  actually manipulating the image. \n* '''Stability''' Opening up the codec to the public allows for democratic and rapid improvements and bug fixes.\n\n<br>\n==RAW==\nA core feature of UAD is the ability to encode and decode ''raw'' image sensor data. By recording raw sensor data, the image processing pipeline is no longer confined to running on the hardware of the camera within the time duration of one ''frame''. This not only allows for more complex higher quality raw processing but also far more creative control over how the image is ''developed''.\n\n\n====Efficiency====\nRaw sensor data from a colour image sensor contains only a single colour channel per ''pixel''. It is only after debayering this raw data that the image contains the three expected ''red'', ''green'' and ''blue'' channels per pixel. This transformation of one channel into three channels increases the image size by a factor of three. For this reason, it is much more efficient to encode image data prior to the debayering transformation.\n\n\n====Performance====\nThe debayering and image processing phase evaded by raw acquisition must still be done in order to display the final image. The workload of a raw decoder is therefore much greater than a typical non-raw image format. UAD implements the entire debayering and image processing pipeline in a single OpenCL program allowing for efficient real-time 8K raw playback on mid-range computer hardware. Additionally, UAD can decode natively at half and quarter resolutions, allowing for smooth real-time playback on lower-end or mobile class computer hardware.\n\n\n====Creative Control====\n[[File:uad-raw-plugin-usage.png|thumb|UAD-RAW Source Settings in Premiere Pro]]\nNot all raw formats provide a rich interface for controlling the ''raw'' developing process.\nUAD-RAW and the [[UAD CODEC PREMIERE PRO PLUGIN|UAD plugin for Adobe Premiere Pro]] provides far more than simple exposure and white balance sliders - shape noise, adjust tone-mapping, configure gamma/colour spaces and more."
