In an age where even consumer cameras record progressive 1920 x 1080 HD video in a standardized video codec and in a wide variety of frame rates it may be easy to forget how complex early HD production was. Early HD adopters had to navigate a wide array of early HD video resolutions and formats, often specific to the camera manufacturer. Most early “1080” video formats, like HDV and DVCPRO 100,...

CUDA (Compute Unified Device Architecture) is a parallel computing and programming platform developed by NVIDIA. CUDA technology is important for the video world because, along with OpenCL, it exposes the largely untapped processing potential of dedicated graphics cards, or GPUs, to greatly increase the performance of mathematically intensive video processing and rendering tasks. By leveraging... READ MORE

One of the most confounding aspects of 4K video production is the lack of accepted standards. And like many other parts of the emerging 4K workflow, 4K video signals are done in many different ways. The biggest problem is that there is still no broadcast standardized SMPTE 4K signal. Without a supported professional method for distributing 4K most companies have had to improvise. Some use...

The concept of using an external device to record video is virtually as old as the concept of video itself. In their earliest form, portable video recorders took the form of large, heavy backpacks powered by a lead-acid battery belt, both worn by the camera operator. Even at this size portable recorders only offered what today would barely be considered standard definition resolution. ... READ MORE

Software capable of importing and manipulating 4K video is not necessarily a new development.  Many, if not most, nonlinear software packages have been resolution independent since the early days of HD. The barrier to running 4K on the desktop hasn't been the software, but rather, the hardware on which it runs. Until fairly recently, real-time 4K performance was relegated to only the most high-...
