Video encoding apparatus and video encoding method

A video encoding method comprising:

• performing a video encoding operation on an original video frame by an encoding circuit to generate an encoded video frame, wherein at least one encoding information is generated by the video encoding operation during an encoding process;
• obtaining an initial ROI within the original video frame;
• and
• reusing the encoding information generated by the video encoding operation to identify one or more ROI objects according to the initial ROI and generate one or more dynamic ROIs for tracking the one or more ROI objects within a current video frame for any one of a plurality of sequential video frames following the original video frame,
• wherein the step of reusing the encoding information generated by the video encoding operation to generate the one or more dynamic ROIs for tracking the ROI objects comprise:
• generating mark information for marking respective positions of the one or more dynamic ROIs based on the encoding information by the ROI determination circuit.
