Abstract

The present teachings relate to the field of video encoding. In particular, the present teachings relate to a method, device, and system for encoding a sequence of frames wherein a motion level of image data of an initial frame in the sequence of frames is determined to be below a motion level threshold. The encoding method described herein may reduce the bit rate for the encoded sequence of frames, while avoiding that the encoded video stream looks unnatural or frozen when decoded and displayed.
