The source video files I want to convert to Blu-ray compliant<br>
MPEG-2 SD video with LPCM audio are:<br>
1) DV25.dv, 720 x 576 (PAL), 50i 4:2:0 video with LPCM stereo<br>
audio<br>
and<br>
2) SD ProRes.mov, 422 (HQ) 19-bit video with LPCM stereo audio<br>
<br>
The purpose is to get better MPEG-2 quality using higher<br>
(highest) possible bitrate than for DVD video.<br>
(Yes, I have tested h.264 via Cin-GG)<br>
<br>
<br>
Here a sample ffmpeg command script found for HD video with<br>
PCM (Blu-ray not mentioned):<br>

Thank you for your review and suggestions. I'll put the pieces together tomorrow and start testing with em...<br>

for SD files replace '-s 1920x1080' with '-s 720x576' or omit this part {better} .<br>

<br>
Not sure how to treate 720x576 (4:3) with regards to displaying on a 16:9 Widescreen (HDTV), possibly crop the frames next to<br>
SD Wide (16:9) "These resolutions are stored anamorphically, i.e. they are stretched to the display aspect ratio by the player or display."</blockquote><div><br></div><div>yeah, I missed this part... hopefully there will be simple chain of arguments to ffmpeg for this! </div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

'-b:v 40M -maxrate 40M -minrate 40M'. for 40 mbit/s fixed bitrate. for smaller bitrate just replace numbers.<br>
<br>
-f m2ts for mpeg2 transport stream.<br>
<br>
most likely remove -pix_fmt part.<br>
<br>
-i your file (ffmpeg hopefully will detect its type and codecs automatically)<br>

So any Mpeg2 Profile@Level is neither required as discussed here:<br>

keep -c:v mpeg2video part<br>
<br>
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)<br>

PCM and ffmpeg was also discussed here<br>

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).<br>

<br>
Yep, tsMuxer still launches fine from my Appimage installation. I'll have a look at it later....<br>

Suggestion to FFMpeg command to convert the actual SD video<br>
files Blu-ray compat?<br>
And if LPCM has to be muxed via MP4(Box) first, a guideline<br>
is welcome?<br>
<br>
------------------<br>
Some Blu-ray technical info and specifications:<br>
Video codec MPEG2 - MP@ML (4:3 or 16:9), MP@HL (16:9)<br>
Video frame size 720×576 25 frames interlaced / 50 fields<br>
(4:3/16:9)<br>
Max video bitrate 40 Mbit/s<br>
**BD-R/RE AV SESF, Part 3 (2018):<br>
Video Streams: max. 15 Mbps VBR (MP@ML) and 24 Mbps (MP@HL)<br>
Audio codecs LPCM 1.536 Mbps (16 bit, 2 ch), 2.304 Mbps (20,<br>
24 bit)<br>
