Blurring the real and the virtual live
The capture of depth information in scenes is an increasingly rich field of development but it has so far remained on the fringes of TV production because of the need to either use physical markers on objects or to render the output in post. Start-up company Zinemath aims to changeThe Fast Tracking of Slow Motion Video Technology
Slow motion was originally a staple of motion picture production. It was a simple process — each film frame was captured at a speed much faster than it was played back. When replayed at the normal speed of 24 frames per second, time appeared to be moving more slowly. …Understanding Compression Technology: Predicted Frames and Difference Frames. Part 3.
In Part 2 of this series on Compression Technology we learned how Motion Vectors are generated when motion estimation is employed as the first step of creating P-frames and B-frames. In Part 3 we’ll learn how these motion vectors are used to generate Predicted Frames. …4K Cameras in 2/3 format for UHD Production
Grass Valley and Hitachi both showed 4K cameras for the UHD production market at IBC 2014. Cameras with 2/3 in sensors are thought to deliver the ideal depth of field and sensitivity for general studio and sports production. Although the super 35 format is good for cinematography, accurate focusing can be challenging. NotUnderstanding Compression Technology: Motion Estimation Part 2
Part 1 of this article covered multiple aspects of compression technology: macroblocks, DCT, quantization, and lossless compression. Part 2 will focus on motion estimation for P- and B-frames—after a review of lossless data compacting. Part 3 (next month) will detail the critical role of Predicted frames and Difference frames in maintaining image qField Video Recorders Ride the Popularity of DSLR Video Cameras
DSLR cameras get smaller, lighter and more powerful. …Taking graphics to the next level
As graphics’ technology gets better, it becomes more difficult to tell the difference between real and software-generated imagery. …Channel-in-a-Box Technology is Driven By Fast Growth of New Television Channels
Viewers and broacasters all want more channels. …
