Samsung uses the occasion of Photokina 2014 to launch a camera that's sure to entice not only photographerss, but may lure video shooters as well, featuring 4K recording to H.265, a world's first.
Researchers at the University of Bath claim to have invented a codec based not on pixels but on vectors. Vector graphics have been around for a long time but until now they have not been considered to be suitable for general purpose image work - and certainly not for video - because while they have distinct advantages, they are difficult to use where images are complex
Even though many pundits think 4K will be delivered by streaming, there are plenty of households still with slower broadband for whom this will not be an option. Now, it seems, Google's free VP9 codec might be a candidate for a new "Blu-Ray" format
A surprise upgrade for Sony's shoulder-mount ENG cameras means they can record HD with the same quality as visually lossless ProRes
For most of the history of film, if you wanted to insert something into the picture that didn't exist, the camera had to be stationary. Motion tracking allows artificial objects to be inserted convincingly into real footage. Phil Rhodes explains
It’s a great pity that in order to enjoy the benefits of digital imaging, we must use pixels that may only be one of a comparatively small selection of colours, as opposed to the effectively infinite subtlety of nature. Phil Rhodes spreads light and understanding about quantization and noise.
In a major new article, Phil Rhodes explores the background to HEVC/H.265, and explains what makes it so good at compressing video. Read this if you want to know how almost all video - including 4K - will be delivered in the near future
