Gamut. A typical CRT gamut. The grayed-out horseshoe shape is the entire range of possible chromaticities, displayed in the CIE 1931 chromaticity diagram format (see below). The colored triangle is the gamut available to a typical computer monitor; it does not cover the entire space. The corners of the triangle are the primary colors for this gamut; in the case of a CRT, they depend on the colors of the phosphors of the monitor. At each point, the brightest possible RGB color of that chromaticity is shown, resulting in the bright Mach band stripes corresponding to the edges of the RGB color cube. In color reproduction, including computer graphics and photography, the gamut, or color gamut /ˈɡæmət/, is a certain complete subset of colors. Introduction[edit] When certain colors cannot be expressed within a particular color model, those colors are said to be out of gamut.

PANORAMAS. Canon speedlite 430exII - The Photo Forum - Photography Discussion Forum. Apple's ProRes 422 : Apple Final Cut Pro Tutorial. 205 posts in 11 forums! As I write this Wednesday, May 30 2007, that's the number of posts we've seen on Apple's new ProRes 422 codec here at Creative COW in just the past two weeks! It's an understatement to say that this is the most talked-about topic in our communities right now. Needless to say, it's impossible to summarize all of that information into even a very long article.
I'm going to try to do it in TWO very long articles. Even so, I'll just be getting started. This small sample is taken just as Final Cut Studio 2 hits the streets. For the record, barely half of the posts are in the Final Cut Pro forum. See what I mean? To keep things balanced, I've based this article on the most active conversations in 8 of those forums. It happens that HDV is a special case. Any guesses on the number 2 forum for HDV ProRes posts after FCP? Apple Color, with twice the number of mentions of ProRes workflows for HDV found in the HDV forum! A quick confession: I've yet to install FCS 2.

It was launched in 1995 with joint efforts of leading producers of video camera recorders. The original DV specification, known as Blue Book, was standardized within the IEC 61834 family of standards. These standards define common features such as physical videocassettes, recording modulation method, magnetization, and basic system data in part 1. DV compression[edit] DV uses lossy compression of video while audio is stored uncompressed.[2] An intraframe video compression scheme is used to compress video on a frame-by-frame basis with the discrete cosine transform (DCT).
Closely following ITU-R Rec. 601 standard, DV video employs interlaced scanning with the luminance sampling frequency of 13.5 MHz. Prior to the DCT compression stage, chroma subsampling is applied to the source video in order to reduce the amount of data to be compressed. Digital Interface Format[edit] Baseline DV employs unlocked audio. Variants[edit] AVCHD. AVCHD (Advanced Video Coding High Definition)[1] is a file-based format for the digital recording and playback of high-definition video. Developed jointly by Sony and Panasonic, the format was introduced in 2006 primarily for use in high definition consumer camcorders.[2] Favorable comparisons of AVCHD against HDV and XDCAM EX[3][4] solidified perception of AVCHD as a format acceptable for professional use. Both Panasonic and Sony released the first consumer AVCHD camcorders in spring of 2007.[5] Panasonic released the first AVCHD camcorder aimed at the professional market in 2008, though it was nothing more than the (by then discontinued) FLASH card consumer model rebadged with a different model number.
In 2011 the AVCHD specification was amended to include 1080-line 50-frame/s and 60-frame/s modes (AVCHD Progressive) and stereoscopic video (AVCHD 3D). The new modes require double the video data rate than previous modes. AVCHD and its logo are trademarks of Sony and Panasonic.[6] DVD[edit]
