Abstract
A variable frame rate encoding method applied to a video encoder, and the method, by obtaining a current coded macro block: determining whether the current coded macro block is located in a still area and if the current coded macro block is located in the still area, encoding the current coded macro block by using a first preset coding mode, and if the current coded macro block is located in a motion area, then encoding the current coded macro block by using a second preset coding mode.
