It is primarily found in video production and broadcast environments, such as television studios.<\/li>\n\n\n\n<li><strong>HDBaseT<\/strong>: This is a relatively new standard that allows for the transmission of uncompressed high-quality video, audio, Ethernet, controls, and even power over a single CAT5e\/6 cable up to 100 meters long. It is used in professional environments such as AV installations and conference rooms.<\/li>\n\n\n\n<li><strong>NDI<\/strong> (Network Device Interface) is an innovative standard in the field of professional video broadcasting. <strong>Developed by NewTek,<\/strong> it enables the transfer of high-quality video over a local Ethernet network. Additionally, <strong>NDI supports 4K video,<\/strong> making it an <strong>ideal solution for broadcasting high-resolution videos.<\/strong> It is also capable of handling multiple video streams over a single Ethernet cable, greatly simplifying the cabling infrastructure in a video production environment.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Video stream synchronization<\/h2>\n\n\n\n<p>In a video mapping setup using a large number of projectors managed by multiple machines, <strong>video stream desynchronization can pose a significant problem.<\/strong><\/p>\n\n\n\n<p>This desynchronization occurs when the various video sources are not perfectly aligned in time, leading to inconsistent and disruptive visual effects. For example, if an animation is meant to move smoothly across multiple projectors, <strong>desynchronization could cause the animation to be ahead on one projector and behind on another.<\/strong> This issue can be exacerbated when multiple machines are used to control the projectors, as each machine may have slightly different performance levels, leading to slightly different processing and display times.<\/p>\n\n\n\n<p>Additionally, network latencies, differences in video processing speeds, and variations in projector response times <strong>can all contribute to desynchronization.<\/strong> To address this issue, it is crucial to use software or hardware capable of precisely synchronizing video streams across multiple machines and projectors, which often requires advanced technical expertise and careful setup.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">To continue<\/h3>\n\n\n\n<p>Graphic concepts: aspect ratio, resolution, layers, codecs<\/p>\n\n\n\n<p><em>This guide was written by <a href=\"https:\/\/www.heavym.net\/de\/\"><strong>HeavyM<\/strong><\/a>, a company specializing in video mapping since 2013.<\/em><\/p>\n\n\n\n<p><em>For any questions, comments, advice, etc., please use this contact form: <a href=\"https:\/\/help.heavym.net\/hc\/requests\/new\">**<\/a><a href=\"https:\/\/help.heavym.net\/hc\/requests\/new**\">https:\/\/help.heavym.net\/hc\/requests\/new**<\/a>.
