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:

not dure how well this particular case was tested ... may be it worked because player/TV automagically forced 16:9 ?

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 ..
