Video Compression Add the video file to be compressed to the software, click the Advanced Settings button behind the preset scheme to reset the parameters of bit rate and frame rate, and then click the OK button to return to the main interface to check the output size of the video file. If it is still relatively large, you need to adjust the bit rate and frame rate again. Click the switch button in the lower right corner after setting.
Time domain of video compression;
Motion compensation of video compression Motion compensation is to predict and compensate the current local image through the previous local image, which is an effective method to reduce redundant information of frame sequence.
Video compression motion indicates that images in different regions need to use different motion vectors to describe motion information. Motion vectors are compressed by entropy coding.
Motion estimation of video compression Motion estimation is a set of techniques to extract motion information from video sequences.
