Constant Bitrate in HEVC

[Selur]

short: Hybrid can't create bit streams without any fluctuation since it's not possible.

long:

• Constant bitrate doesn't mean that the doesn't fluctuate. Real constant bitrate is not really possible with any MPEG based video streams. http://slhck.info/video/2017/03/01/rate-control.html might be interesting.
  
• Don't put your trust in MediaInfo in that regard, see: https://forum.doom9.org/showthread.php?p...ost1811261.
  
• To archive what normally is considered 'constant' bitrate use x265 with '--bitrate X --strict-cbr --vbv-maxrate X --vbv-bufsize X' see: https://bitbucket.org/multicoreware/x265...o-with-cbr
  
• Only container that might show up as constant bitrate is probably transport stream containers (ts, m2ts, mts,..), since there are multiplexer out there that support bitrate stuffing for those.
  

->

• Read up on MPEG compression just the basics should do to understand why constant bitrate doesn't make any sense with MPEG based compression.
  
• Read up on VBV what it is and what it is for and why this is what one normally wants.
