Abstract
A bit rate control method includes the following operations: receiving a first target bit of a video to be coded; determining a second target bit for first coding tree units (CTUs) in CTUs of the video according to the first target bit; determining a fourth target bit of at least one fourth CTU in the CTUs according to an actual bit of at least one second CTU in the CTUs and a third target bit of at least one third CTU in the CTUs, in which the at least one second CTU is completely coded, the at least one third CTU is not completely coded, and a coding of the at least one fourth CTU is not started; and sequentially adjusting at least one coding parameter for coding the video according to the second target bit, the third target bit, and the fourth target bit.
