Encoding Video for Blu-Ray using H264/AVC
Here is part of specification that apply when encoding with H264/AVC codec, all parameters showed here are not guessing, it's based on original Blu-Ray specification, which are not available in public.
NOTE: This is discussion about settings that are for creating 100% compliant Blu-Ray structures, not for encoding from Blu-Ray sources to matroska/mp4 or other media, if you encode to those skip this nightmare 1. GENERAL CONSTRAINTS FOR MPEG-4 H264/AVC 1.1 ALLOWED RESOLUTIONS/FRAMERATES 1.2 ALLOWED LEVELS, PROFILES, REFERENCE FRAMES, VBV 1.2.1 Primary Video Rules 1.2.2 Secondary Video Rules NOTE: In case of 1080 and 720 resolutions same rules apply as Primary video, while 576 and 480 resolutions have stricter parameters showed in table: 1.3 SIMPLE ASPECT RATIO 1.4 COLOR CHARACTERISTICS 1.5 OTHER REQUIRED PARAMETERS 8-bit (4:2:0) Colorspace is only allowed Main and High profiles are allowed Maximum 3 B-Frames is allowed NAL-HRD Type 2 capable encoder is needed 2. ENCODE BLU-RAY VIDEO USING x264 2.1 MANDATORY PARAMETERS Every encode for Blu-Ray must contain this parameters, without it will not meet Blu-Ray specification. Quote:

For example: --vbv-bufsize 30000 --vbv-maxrate 40000 is allowed --vbv-bufsize 30000 --vbv-maxrate 30000 is allowed --vbv-bufsize 15000 --vbv-maxrate 30000 is allowed --vbv-bufsize 30000 --vbv-maxrate 15000 is not allowed (delay is greater than 1 second) Basicly vbv-bufsize should newer been greater than vbv-maxrate, that is whole point.
