![]() ![]() Then Kane moved the smaller screen around to imitate the movement of a motion picture – he asked the attendees if they could see the noise introduced by the granular material on the smaller screen. Of course, the projected image showed on both the smaller screen and the larger one behind it. To demonstrate the granularity problem, Kane held up a smaller screen panel with typical construction in front of the Da-Lite Affinity screen. > Click to see a full slide show from Joe Kane’s Expo presentation, including a series of slides of the construction of a reference theater in his own home. But the granularity of the coating, which Kane calls its coarsivity – while positively enhancing directivity – tends to add visual “noise” and other problems. The coating, over an initial flat screen, is sprayed with a granular material that enhances directivity. The typical video screen is coated with material whose purpose is to enhance directivity. Here again, he began with a short primer on the construction of the typical screen and why most of them are sub-optimal. Screen realities you need to know…Īfter determining that the seminar attendees all understood his position on the topic of resolution, Kane moved on to the originally promoted topic of the seminar: video screens. ” Screens must present color accurately and consistently for optimal performance, Kane told seminar attendees. “And they’re not doing that.”īut for the images in his seminar, “I’m actually doing that – I’m transferring my film at 6K, so that I can down-covert it to 2160p and actually show the differences in picture quality between the two formats. ![]() “Because if they’ve learned the lesson of the other two formats to come before them you know that they have to be transferring at 6K or 8K,” Kane said. If the industry plans to up-scale 1080p content to 2160p, it will not look good, Kane said. Kane, however, is quite skeptical about this claim of content readiness – “No they’re not,” Kane proclaimed. There has been a lot of industry discussion about “a huge amount of 4K material archived” and available for this new format. On successive images, he pointed out greater accuracy in, for example, images with detailed fabrics or complex color shadings. To help demonstrate the point, Kane showed a series of images that were originally created in extremely high resolution and then down-converted to 2160p. Apparently, this was the system employed by the now defunct HD-DVD format which Kane says originated with content from higher resolution sources than used by the Blu-ray camp. If done properly, very fine detail will be revealed. Kane suggested that content should come from original sources at very high resolutions that are then down-scaled to the final 2160p format. “I actually took acting lessons,” Kane told in a separate interview, to help him be a more effective communicator. Kane also was a relatively dynamic speaker who moved around the room and used his voice and his gestures to amplify his message. Not only that, but he also took time to demonstrate concepts or use more easily understood analogies to clarify topics. A techie who can actually communicate with mere mortals… ![]()
