so yeah, seems like sd 16:9 missing. easy to add
I wonder if we should modify 1440*1080 presets to also be
wide always? How it looks now {if source is hdv unscaled}
in real (HD) TV connected to BD player
?
The FHD option 1920x1080 is already available, with or
without scaled from HDV?
right now ot seems to be WITH scaling OR produces 4:3 1440*1080
files. Patches aims at fixing that.
I suggest CinGG supports all valid BD-formats, SD and HDV
anamorphic included. I am currently not rigged to test BD
1440x1080 with BD player and TV, but I think I did test it
previously on a PC display (can possibly test it later by
opportunity).
If not other project reasons, I basically don't see why to
up-convert and store more pixels on the medium, if and when
the 1440x1080 format scales fine to 16:9 by the player/TV.
Just did a simple succesful test with VLC now.
yeahhhh ....
................
I rendered HDV to BD successful now, but got Aspect error both
with None and Scaled:
1) None (scale): a small 4:3 sqeezed image covering 50% of the VLC
display area centered, no cropping:
a little correction: Visually the small image here was 0.5W * 0.5H =
0.25 of the VLC display area.
The same results using ffplay in case 1) and 2)

not dure how well this particular case was tested ... may be it worked
because player/TV automagically forced 16:9 ?
I think ffprobe's output above has to be ....1440x1080 [SAR 4:3 DAR
16:9], indentical to the source HDV below, to display correctly.
I think BD-Render currently is locked to AVCHD (h264) video
and ac3 audio only.
hey, we did lpcm bd audio too some time ago! There must be little
dropdown menu with two choices ...
It would be fine if Create BD also could be extended to offer
compliant mpeg2 video and video copy (smart rendering) with
separate AC3/PCM_bluray audio (ref. Create BD video without
rendering HDV and possibly DVD video).
well, smart render is harder than it sounds even in linear
transcoders based on ffmpeg :/
piping all this info in correct manner using cingg's internal
seems to be beyond that *I* can do.
But we hopefully at very minimum can develop mpeg2_video encoding
profile based on mpeg2 high quality one. But this again require
testing on real media/player - due to bitrate
distribution/rotation speed interplay not emulated when reading
from a file.
I meant video Copy of the compliant 1080i HDV.m2t mpeg2 was a
"smart render" in this case ;)
(There is also additional non-anamorhic 1280x720 HDV available)
I saw the tsmuxer button is also available, so possibly AC3/PCM
then can be muxed together with MPEG-2, similar like I did with
FFmpeg in my previous "Preserving Camcorder Media" chpt 5 page 17
(23)? Just keep (copy) the mpeg2 video as is and transcode the MP2
audio to AC3/ PCM.
internals on cinelerra(-gg) do not carry info about Group of Pictures
from input asset to output one so copying compressed mpeg2 stream is
not possible currently.
Yes, the standard compliant MPEG-2 for HDV.m2t source profile is here:

so idea to test is to manually tweak selected video codec to this
profile in popped-up batchrender window (using small wrench icon) and
fixup bd.sh afterwards when it errors out (not sure if mpeg2 can hang
from same pid as h264 - forgot it all!)
main profile to tweak should be
ffmpeg/video/mpeg2_hq.mpeg
mpeg mpeg2video sc_threshold=-30000
dc=11
bf=2 trellis=2
mbd=rd
cmp=2
subcmp=2 b=4000000
so you ramp up b to 2500000, set g=15 and probably add other options.
And save as another profile :;)
I'll try to look at mlt/openshot, they probably had hdv mpeg2 spelled
out ..
