The source video files I want to convert to
Blu-ray<br>
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<br>
stereo<br>
audio<br>
and<br>
2) SD ProRes.mov, 422 (HQ) 19-bit video with
LPCM<br>
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<br>

PCM (Blu-ray not mentioned):<br>

Andrew,<br>

Thank you for your review and suggestions. I'll put the
pieces<br>
together tomorrow and start testing with em...<br>
<br>
<br>
for SD files replace '-s 1920x1080' with '-s 720x576'
or omit<br>
this part {better} .<br>
<br>
<br>
Not sure how to treate 720x576 (4:3) with regards to
displaying on<br>
a 16:9 Widescreen (HDTV), possibly crop the frames next to<br>
SD Wide (16:9) "These resolutions are stored
anamorphically, i.e.<br>
they are stretched to the display aspect ratio by the
player or<br>
display."<br>

===<br>
for MPEG-2, -aspect is useless; you need to use -bsf:v
mpeg2_metadata=display_aspect_<wbr>ratio=4/3 (the only valid
values are 4/3, 16/9, 221/100). Even this might not work {...}<br>
====<br>
<br>
try to experiment..<br>
<br>
<br>
<br>
'-b:v 40M -maxrate 40M -minrate 40M'. for 40 mbit/s
fixed<br>
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<br>
automatically)<br>
<br>
<br>
<br>
So any Mpeg2 Profile@Level is neither required as
discussed here:<br>

<br>
keep -c:v mpeg2video part<br>
<br>
I do not think you need mp4box for further conversion,
as name<br>
suggest it mostly deals {at output end} with mp4
format, not<br>
mpeg2 transport stream (but you mentioned putting pcm
in mp4,<br>
so I researched this part too)<br>
<br>
<br>
PCM and ffmpeg was also discussed here<br>

try tsmuxer (gui) next (not sure if Appimage works for
you, if<br>
not try their linux build from their github - tags -
assets<br>
(there you need to expand 'assets' arrow/triangle to
see<br>
various binary and source archives).<br>
<br>
<br>
<br>
Yep, tsMuxer still launches fine from my Appimage
installation.<br>
I'll have a look at it later....<br>

==============================<wbr>=========<br>
<br>
I've tried four ffmpeg tests, 1) -4) below with .m2ts and .mp4
containers<br>
I used data rate 25M (comparable with the source dv 25 mbps,
compression 5:1)<br>
-f m2ts not accepted as format<br>
would not copy lpcm audio into any new streams<br>
VLC playback the video files OK - without audio<br>
<br>
Comments and new suggestions welcome ;)</blockquote>

<div>so yeah, it seems '-f mpegts' is way to go. does sound appear
if you replace</div>
<div> -c:a pcm_s16be with pcm_s16le? </div>
