The default value of Hue is 128, which represents phase 0; the value range is 0-255.<\/p>\n<h3>Video preprocessing<\/h3>\n<p>Before video captured and sent to encoder, we can make some necessary preprocessing:<br \/>\n(1) Source picture cropping: Crop a part of the original picture for encoding.<br \/>\n(2) Scaling: After step 1 cropping (or not cropping), video can be scaled up\/down to certain format. (E.g. Input video is 1080p60, scaling down to 720p30 for encoding.)<br \/>\n(3) Second cropping: After the step 2, you can continue cropping the size you want for encoding. (It\u2019s almost the same with step 1, but necessary in specific application.)<br \/>\n(4) Rotation or flipping: It&#8217;s the last step before encoding, you can rotate the video with 90\/180\/270 degrees, horizontal mirror or vertical flip.<\/p>\n<p>Above process is a pipeline from step 1 to step 4. You could choose to open, or prohibit it about each step.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.kiloview.com\/data\/kv-image\/en\/NDI\/E_Series_NDI_Encoder_User_Manul_V2.0\/image40.png\" alt=\"img\" \/><\/p>\n<h3>Audio signal source<\/h3>\n<p>Audio source \u201cAuto selection\u201d mode is automatically to select the embedded audio of the input video source.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.kiloview.com\/data\/kv-image\/en\/NDI\/E_Series_NDI_Encoder_User_Manul_V2.0\/image41.png\" alt=\"img\" \/><\/p>\n<blockquote>\n<p><strong>Note: E series products are without Analog Line in and doesn\u2019t support adjust analog input gain.<\/strong><\/p>\n<\/blockquote>\n<\/blockquote>\n","protected":false},"featured_media":0,"parent":4251,"menu_order":3,"comment_status":"open","ping_status":"closed","template":"","doc_tag":[],"class_list":["post-48466","docs","type-docs","status-publish","hentry"],"acf":[],"aioseo_notices":[],"comment_count":0,"_links":{"self":[{"href":"https:\/\/www.kiloview.com\/en\/wp-json\/wp\/v2\/docs\/48466","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.kiloview.com\/en\/wp-json\/wp\/v2\/docs"}],"about":[{"href":"https:\/\/www.kiloview.com\/en\/wp-json\/wp\/v2\/types\/docs"}],"replies":[{"embeddable":true,"href":"https:\/\/www.kiloview.com\/en\/wp-json\/wp\/v2\/comments?post=48466"}],"version-history":[{"count":0,"href":"https:\/\/www.kiloview.com\/en\/wp-json\/wp\/v2\/docs\/48466\/revisions"}],"up":[{"embeddable":true,"href":"https:\/\/www.kiloview.com\/en\/wp-json\/wp\/v2\/docs\/4251"}],"next":[{"title":"Encoding & Steam","link":"https:\/\/www.kiloview.com\/en\/docs\/e-ndi-serial-lan-encoder\/function\/encoding-steam\/","href":"https:\/\/www.kiloview.com\/en\/wp-json\/wp\/v2\/docs\/48628"}],"prev":[{"title":"Change WEB login password","link":"https:\/\/www.kiloview.com\/en\/docs\/e-ndi-serial-lan-encoder\/function\/change-web-login-password\/","href":"https:\/\/www.kiloview.com\/en\/wp-json\/wp\/v2\/docs\/48718"}],"wp:attachment":[{"href":"https:\/\/www.kiloview.com\/en\/wp-json\/wp\/v2\/media?parent=48466"}],"wp:term":[{"taxonomy":"doc_tag","embeddable":true,"href":"https:\/\/www.kiloview.com\/en\/wp-json\/wp\/v2\/doc_tag?post=48466"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
