vkdt is a workflow toolbox for processing raw still photographs and video on Linux, macOS, and Windows. Its pipeline connects multiple inputs and outputs in a node graph, using GLSL shaders and Vulkan. Photography tools include colour management, noise profiling, a folder-based image database, automatic parameter optimisation, and U-Net-based denoising. The maker also describes real-time workflows for animations, timelapses, and raw video, including Magic Lantern MLV and MotionCam inputs. Documented formats include JPEG, OpenEXR, raw stills, MLV, MotionCam raw video, and video for input; listed exports include JPEG, JPEG XL, OpenEXR, PFM, BC1, H.264, ProRes, and video. A command-line utility substitutes export nodes for display nodes. vkdt is free. It requires a Vulkan-capable GPU; the maker recommends 4 GB of video RAM, or at least 8 GB for large graphs or images above 50 megapixels.
