Three elements of quality live security analysis

In the broadcast building process, often ignore some problems, the studio is the need to safeguard the quality bit rate, frame rate, resolution of the three equilibrium job Tinto Magic technology specifically as follows:
1. The frame rate
live process , the frame rate easily affect fluency of the screen, the frame rate refers to the number of frames in a second picture transmission, it can be understood as the number of times per second to refresh the graphic processor. The larger the frame rate, the smoother the live picture; frame rate smaller, more powerful judder. Among them, the frame rate will directly affect the volume of the video, the more species per second through the screen, the higher the required rate, the volume of the video will be greater.
2. Resolution
directly affects the size of the live image, the larger the higher the image resolution, the lower the resolution, the smaller the image.
3. sharpness
during a broadcast, if the code rate is fixed, then the resolution and clarity inversely, that is, in the case where the same bit rate, the higher the resolution, the image is not clear, the resolution low, the clearer the image. Resolution is fixed, the higher the rate, the clearer the image, the lower the resolution, the image is not clear.
If you do not rate the size limit, the higher the resolution, the higher the quality of live, the higher the frame rate of the video will be more smooth, the corresponding rate will be great. Because more data per second needed to carry higher clarity and fluency, in ensuring the clarity and fluency, flow of consumption will also increase, due to expenses will also change More.
In developing live APP software, if a fixed value to the bit rate, the higher the frame rate to increase the compression encoder more than a single frame, which is carried by a sufficient image degradation frame, if it is to use the camera to obtain video content, the human eye's limit the number of frames is 24FPS, then too clear picture of it may cause discomfort, watch live, in general, has reached 20 ensures that the user's experience.
If the resolution is too high will exert more pressure caused by the encoder, it is necessary to carry a sufficient number of pixels by means of reducing the color information or the introduction of Mosaic, the fixed bit rate case, the same volume of video, 1080p may not 720p looks clear.
