Abstract: An electronic device is provided. The electronic device includes a memory and a processor operatively connected to the memory, wherein the processor may obtain a maximum allowable bit rate of the electronic device, determine a maximum quantization value for encoding an image composed of at least one frame, obtain a first bitrate by encoding a first frame set of the image with a quantization value equal to or less than the maximum quantization value, increase the maximum quantization value in response to the obtained first bitrate exceeding the maximum allowable bitrate, decrease the maximum quantization value in response to the obtained first bitrate being less than or equal to the maximum allowable bitrate, obtain a second bitrate by encoding a second frame set subsequent to the first frame set of the image based on the increased or decreased maximum quantization value, increase the maximum quantization value in response to the obtained second bitrate exceeding the maximum allowable bitrate, and decrease the maximum quantization value in response to the obtained second bitrate being less than or equal to the maximum allowable bitrate.
