Fast CinemaDNG Processor on GPU

We have designed high quality CUDA-accelerated solution for CinemaDNG processing with very high performance - much faster than realtime. Now it's possible by implementing full CinemaDNG processing pipeline on NVIDIA GPU with CUDA technology.

Advantages of Fast CinemaDNG Processor

• 4K CinemaDNG processing at 24-30 fps, up to 60 fps
• 8K DNG photo editing with fast response
• High performance DNG decoding on CPU
• RAW Curves and Levels before demosaicing
• High quality demosaicing with MG algorithm
• High speed denoising for raw, luma and chroma
• No proxies, 4K dailies can be processed in realtime
• Smooth and scalable Player for CinemaDNG footages
• MLV and DNG player, viewer, converter, transcoder
• Software for footage Culling and Reviewing before editing

We have implemented full image processing pipeline on CUDA to make fast each stage of RAW data workflow. That gives us opportunity to significantly decrease data transfer time over PCI-Express bus and to improve total performance. Now we can do CUDA-based DNG rendering much faster than real time. At the same time, output image quality is comparable with Adobe Camera Raw (ACR) and LightRoom (LR), etc.
