'-b:v 40M -maxrate 40M -minrate 40M'. for 40 mbit/s fixed bitrate. for smaller bitrate just replace numbers. -f m2ts for mpeg2 transport stream. most likely remove -pix_fmt part. -i your file (ffmpeg hopefully will detect its type and codecs automatically) keep -c:v mpeg2video part I do not think you need mp4box for further conversion, as name suggest it mostly deals {at output end} with mp4 format, not mpeg2 transport stream (but you mentioned putting pcm in mp4, so I researched this part too) try tsmuxer (gui) next (not sure if Appimage works for you, if not try their linux build from their github - tags - assets (there you need to expand 'assets' arrow/triangle to see various binary and source archives). >> >> >> Suggestion to FFMpeg command to convert the actual SD video files Blu-ray >> compat? >> And if LPCM 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 LPCM 1.536 Mbps (16 bit, 2 ch), 2.304 Mbps (20, 24 bit) >> ----------------------- >> >> Terje J.
