Frame rate, code stream and resolution

file size is not controllable until you use a quality-based encoding method. There are many coding formats, and in the case of continuous improvement of technology, various coding formats are produced for different purposes. Different encoding format of the compression rate is not the same, and have their own characteristics, some in the low bit rate situation can maintain a higher picture quality, but in the case of high bitrate but the picture quality is not very good, some suitable for high-
