The source video files I want to convert to Blu-ray compliant MPEG-2 SD video with LPCM audio are: 1) DV25.dv, 720 x 576 (PAL), 50i 4:2:0 video with LPCM stereo audio and 2) SD ProRes.mov, 422 (HQ) 19-bit video with LPCM stereo audio The purpose is to get better MPEG-2 quality using higher (highest) possible bitrate than for DVD video. (Yes, I have tested h.264 via Cin-GG) Here a sample ffmpeg command script found for HD video with PCM (Blu-ray not mentioned): https://gist.github.com/avoidik/153879c06afdcaad8d69b38bcc00abb7 # with PCM 16-bit audio (uncompressed), constant video bitrate with specific bitrate tolerance ffmpeg -i "input.mp4" \ -c:v mpeg2video -pix_fmt yuv422p -refs 1 -bf 2 -b:v 50M -maxrate 50M -minrate 50M \ -s 1920x1080 -aspect 16:9 \ -c:a pcm_s16be -f vob \ "output.mpg" Suggestion to FFMpeg command to convert the actual SD video files Blu-ray compat? And if PCM has to be muxed via MP4(Box) first, a guideline is welcome? ------------------ Some Blu-ray technical info and specifications: Video codec MPEG2 - MP@ML (4:3 or 16:9), MP@HL (16:9) Video frame size 720×576 25 frames interlaced / 50 fields (4:3/16:9) Max video bitrate 40 Mbit/s **BD-R/RE AV SESF, Part 3 (2018): Video Streams: max. 15 Mbps VBR (MP@ML) and 24 Mbps (MP@HL) Audio codecs LCM 1.536 Mbps (16 bit, 2 ch), 2.304 Mbps (20, 24 bit) ----------------------- Terje J.
