Video source choice and adjustments<\/h3>\n

Users can choose video source, adjust brightness, contrast, saturation and hue parameters of the video here.<\/p>\n

\"img\"<\/p>\n

\u201cAuto Selection\u201d means the device will check each video source and automatically select the one which has signal.<\/p>\n

\u201cAuto Selection (one-shot)\u201dsame as \u201cAuto Selection\u201d but once it selected a source, it ‘lock’ this and never change unless you ‘Quick Reset’ or ‘Reboot’ the device!<\/p>\n

The value range of Brightness, Contrast, Saturation and Hue is 0~255, default is 128. Based on the median value, the increase\/decrease value corresponds to the increase\/decrease in brightness\/contrast\/saturation. The default value of Hue is 128, which represents phase 0; the value range is 0-255.<\/p>\n

Video preprocessing<\/h3>\n

Before video captured and sent to encoder, we can make some necessary preprocessing:<\/p>\n

    \n
  1. Source picture cropping: Crop a part of the original picture for encoding.<\/li>\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.)<\/li>\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.)<\/li>\n
  4. Rotation or flipping: It’s the last step before encoding, you can rotate the video with 90\/180\/270 degrees, horizontal mirror or vertical flip.<\/li>\n<\/ol>\n

    Above process is a pipeline from step 1 to step 4. You could choose to open, or prohibit it about each step.<\/p>\n

    Audio signal source<\/h3>\n

    Audio source \u201cAuto selection\u201d mode is automatically to select the embedded audio of the input video source.<\/p>\n
