VBITRATE - it's average bitrate which is set for codec for entire stream
(it depends at image complexity and bitrate control over stream by
codec, whatever it will be reached in the end - 2 pass encodings helps a
lot for managing that perfectly)
VRC_MAXRATE - it's maximum which could be reached in a single frame
(can't be higher than that and some frames could easily exceed that -
whereas some hardware decoder have problem if it's too high)
MUXRATE - it's maximum which can be stored in a container altogether:
video, audio, subtitles, other streams
