Bit rate regulation module (3) comprising: a selection block (31) configured to select a frame type to be used to encode a current frame of a video, a determination block (32) configured to determine a target number of bits to be used to encode the current frame, and a computation block (33) configured to compute a quantization step to be used to encode the current frame by using a rate model taking into account a quantization step of a previously encoded reference frame and by modelling rate variations due to a quantization step change between the previously encoded reference frame and the current frame.
