Guide to convert BD 3D to 3D Left+Right Stereoscopic and Anaglyph

[MaistroX]

Another request by me (and I belive alot of ppl.) is:

1. Being able to crop/rezie with preview, needed sometimes on some movies.
2. Since the convert of subtitles works perfect now (at least for me) from BD3D disc to 3D subtiles, have a either standalone "app" that ONLY pics subtitles and convert them to 3D subtiles and/or integrate it as a standalone option, for one to use when 3D subtiles ONLY are needed (and they are from time to time).

Something that can be done/implemented?

Regards MaistroX

If you have only one or two cpu cores, the cpu usage will probably be higher, and that could explain the less important difference of the encoding times.

Also, x264 is much demanding of memory. (It consumes about 2GB when I encode with ssifSource) and, if you don't have enough memory and the system must swap, the duration of the encoding may increase dramatically.

Thanks for the tests. I'm using X264 "slow" encode, and afair my Quad-Core was also at 100% with SSIF-Source. I have 6GB RAM, so that should not be an issue.

As I already posted I got higher fps than you with SSIF-Source, in especially taking into account, that i use "slow" profile, maybe RAM is a limitation for you!?

You can already enable the -core flag. Look in tab 2 (Select Streams). However, as far as I know, the -core flag is used only to extract the 5.1 audio from a 7.1 DTS file, not to convert to AC3.

I know that eac3to can convert the audio streams to other formats (including AC3), but I don't want to do another eac3to frontend. The philosophy of my GUI is to convert a 3D BD to MK3D with as less quality loss as possible. And, if you wish, you can easily convert the DTS track to AC3 and mux it manually. However, I may include that option if several users want it. (Not sure how to do it btw. Is it sufficient to change the extension of the output file to force eac3to to convert a DTS stream to AC3?)

It's not easy, as Tcl/Tk (the scripting language I've used to write BD3D2*) has nothing to show a video. Also, since currently, it is impossible to seek in the input video, the user will have to pick a frame at the very beginning of the movie. Not very practical.

Furthermore, I've explained several times that it is not a good idea to crop the image, because most 3D hardware players (including almost all 3D TVs) require true 16:9 to display correctly a SBS or T/B movie. So, cropping the black borders of a Cinemascope movie is not recommended. It may work fine with software players, but if you buy a new 3D TV, you will probably have to re-encode all your 3D-BDs. I don't want to encourage the users to crop their movies.

For a similar reason, I think that resizing is usually not a good idea, except if you resize to 720p, and BD3D2MK3D can already do that.

Anyway, again, if you really want to crop or resize, you can do it in the avisynth script before launching the encoding.

Look in the Tools menu. I have already implemented that option. It's not a totally independent GUI, but you don't need to load a BD in BD3D2MK3D to convert an existing 2D subtitle in SUP, SUB/IDX or XML/PNG format to 3D. (The same formats are supported for the output, but SUB/IDX is assumed by default.)

Note also that Suppe3D is a simple CLI tool that has been developed because BDSup2Sub++ cannot do the 3D conversion yet, but it should be able to do it soon. When it will be available, you will have the perfect tool, with a nice GUI.

No, I have 4GB of RAM and it's sufficient.

I suppose you have 100% of CPU usage because you encode with the slow preset. Since x264 spend more time in encoding, it is the bottleneck, and ssifSource has enough time to decode. BTW, IMO, with ssifSource, it's the way to go. Since it cannot decode quickly, it is a good idea to set the x264 preset to the highest speed that consumes all CPU power. This way, you can improve the quality with only a small speed penalty. With DirectShowMVCSource, if you lower the speed, the process will certainly take a longer time.

Hi !
I'm trying your software and it's very good
Do you mind it's possible to add :
- encode with 2pass (to get a fix video size)
- export the final script with x264 encode, avs script, etc...
In which language do you program ?
Thank you !

[MaistroX]

I know, but since I´d like to be able to ONLY get get 3D subtitles from a BD and/or extracted, converted to 3D subtitles SBS (option for Over/Under maby allso) and that cant be done without debuxing BD, it world be nice to have that option allso!

Sorry forgot one...


Agree to above req: - encode with 2pass (to get a fix video size)

Can you please set an box/option to be able to write in IF on want to set a kpps for a rip?
An easy way if one wants to have on rip in like 10000 kbps and another one 8500 kbps!
And if not to complicatied, if one can see the estimated total size if one sets it to ex: 10000 kbps!

Thanks again for the answer. That's what I'm doing now. But it was worth asking since there are some people out there preferring AC3 over DTS (especially since this is easy to do using eac3to).

Anyway - I tried to encode Tron Legay 3D using BD3D2MK3D. As the movie consists of two SSIF files, the following AVS script is generated:

part1 = DirectShowMVCSource("X:\BDMV\STREAM\SSIF\00131.m2ts", stf=OVERUNDER_L)
part2 = DirectShowMVCSource("X:\BDMV\STREAM\SSIF\00133.m2ts", stf=OVERUNDER_L)
last  = left1 + left2
AssumeFPS("ntsc_film")
# Anaglyph and Interleaved modes are in RGB32, and must be converted to YV12.
#ConvertToYV12(matrix="PC.709")

With this script, the encoding (obviously) fails immediately (wrong file names, leftX instead of partX parameters). After changing the script to the following, however, the encoding works just fine:

part1 = DirectShowMVCSource("X:\BDMV\STREAM\SSIF\00131.ssif", stf=OVERUNDER_L)
part2 = DirectShowMVCSource("X:\BDMV\STREAM\SSIF\00133.ssif", stf=OVERUNDER_L)
last  = part1 + part2
AssumeFPS("ntsc_film")
IsRGB() ? ConvertToYV12(matrix="PC.709") : last

I agree that that can be useful. Originally, in BD3D2AVS, the decoding phase was so slow that 2 passes was almost impossible. But with the new faster method, 2 passes can be useful. I'll have to modify the GUI much, so don't expect it soon, but I add it in my to-do list.

I'm not sure I understand. Do you want an option to save the current project settings, to reload it later in the GUI? Unfortunately, it's very difficult. The BD must be scanned anyway, and the parameters may differ if, for example, the BD is in another drive. Furthermore, I haven't build the program with that possibility in mind, and adding that feature would require to modify it completely. Sorry.

For my GUIs, I use Tcl/Tk. It is very powerful to build complex GUIs, but it's a slow interpreted language, and it has its drawbacks. (I wrote PgcEdit almost entirely in Tcl/Tk, and that was certainly a bad idea, because at the beginning, my intention was to write only a simple GUI.)

You would like the possibility to convert a subpic stream from the BD directly, without demuxing it first? Right?
Sorry, but that's currently impossible. You need to demux it, either with my app, or with any eac3to GUI, then use the tool to convert it to 3D.

If it is really sufficient to change the output extension to AC3, I can probably add that feature in the next version...

Oops, obviously, I forgot to modify some lines of code after a copy/paste.
Sorry, that app is difficult to test, especially because each test requires much time, and there are many combinations of options to test.
Anyway, I will fix that bug. Thanks for the precise bug report!

[EDIT] Bug fixed. I'll release v0.4 tomorrow. I will first see if I can add the conversion to AC3 easily.

I'm agree with you, it's a little confused. I would like to see what command line is launch to encode, for example "x264 -option1 -option2=x -option3=y..." and the avs script generated by your program

Not sure. It depends of the difficulty. Perhaps in one week or so.

Well, the script and the x264 commands are generated after the demux phase, as they change if, for example, a stream cannot be demuxed. (It's often the case if you ask to mux a subtitle stream with forced captions only, and there are no forced captions in the stream.) Therefore, I can't display the command and the script before the end of the job. If you want to examine them, you have two options. Open the script of the batch files in notepad, or have a look at the console (in the Files menu). The commands that are executed are displayed in the console, as well as the content of the script and batch files.

Thanks for your proposition. But if you know C++, I suggest to help Neisklar in debugging DirectShowMVCSource. IMO, the most important thing to do currently is to fix the "seek bug". (Without that bug, it will be much easier to preview the 3D movie, for example to try the depth of the 3D subtitles.) DirectShowMVCSource is the important program to develop and maintain, and my GUI is only, well, a GUI!

[r0lZ]

Here is v0.4 of BD3D2MK3D. It fixes this bug, and I've added the possibility to convert DTS and WAV audio tracks to AC3 during the demux phase.

BTW, currently, the -core option is automatically set when the conversion to AC3 is enabled, as I don't think it makes sense to convert a 7.1 DTS track to AC3. Am I right?

As always, it has been only roughly tested, but the conversion to AC3 seems to work well, and the bug is really fixed. :-)

# v0.4 (October 23, 2012)
# - Added option to convert DTS and WAV audio streams to AC3 in tab 2.
# - Bug: Wrong file and part names in AVS script when a MPLS is made of several SSIF files.

This gets even stranger as I've tried 3 different editions of this movie (US/EU/Nordic) - all of them fail while every other disc works.
Also, the 3 editions don't share the same encodes, files or playlists. One disc has the ebtire movie on 1 ssif while others have it split across many.

The rips are fine as all discs play flawlessly on every player I tried (in both 2D and 3D).

I also tried actually demuxing left and right .h264 files and feeding those to the ssifsource instead of a playlist or ssif file - same result, it just won't decode.

I'm completely stumped.

Is there a blu-ray protected disc? If so, you should use AnyDVD tool first.

Apparently, alex-pk modified it to support MVC, and god only knows who alex-pk is and where can we find a newer version of the decoder.

God I wish I could figure out a way to load/register CoreMVC from Stereoscopic Player as a directshow filter. I know Stereoscopic Player uses it as a filter, but regsvr32 fails to register it (probably by design).

As I investigated, he is one of the users from http://torrents3d.ru/ But he doesn't reply for private messages.

That strange. I've added that info into usage script example in every package I've uploaded.

IMToo Blu-ray 3D Ripper isn't bitrate limited, but it applies some sort of weird filter to the video (or it's just a very bad encoder) so that even at 80mbit/sec, picture quality is less than ideal.

Lastly, we have ldecod/ssifsource/h264stereosource which just can't decode it and doesn't look like there'll ever be a new version.

Then we have Stereoscopic Player which does include a wonderful directshowsource MVC decoder by CoreCodec (CoreMVC) but has the DLL of the filter unregisterable (regsvr32 fails) even though Stereoscopic Player uses it in a directshow graph.

There is just no way out ;(

I've solved that problem already, but I quite late, though.
Shall I upload my example of usage of StereoPlayer's CoreMVC decoder?

That's true. Another way is to wait a new Intel Media SDK MVC decoder. They promised to add blu-ray format support.

(BTW, due to limitations in the Stereo Player filters, it doesn't work either with MPLS files. Pity!)

I suppose you need something to source a h264 stream, right? IMO, the best method is to mux it to mkv, and then use DirectShowSource.

The problem is that right.h264 can not be simply decoded, because it uses parts of left.h264.

I think at the next stage (if we shall have errors with CoreMVC) we have to read blu-ray stream format documentation. Because if alexpk could add that functionality to ldecod, why we can not?

Please, send a link to the video source, from where you got it. I'll try to find out the issue that causes it.

I've noticed that right view decoded by CoreMVC has frame count less by 1 than the left view. And it might be a bug of CoreMVC decoder.

Please, keep in mind that if you do use 32-bit version of any application (x264.exe, for example) there is ONLY 2GB RAM available for it.

Absolutly yes, so we can learn from each others ways to use it, and make an more robust and stable solution.

That's true. Another way is to wait a new Intel Media SDK MVC decoder. They promised to add blu-ray format support.

Yeah, i read it, that promise was made already some month ago, and still no release of the mvc part.
Also it seems there is noone from the ffmpeg group working on MVC.

eac3to will automatically downmix the rear-surround into the surround-channels, but extracting the Core should be fine, as the core should exactly incorporate the downmixed 5.1 per definition.

There is an MVC Decoder (even as DirectShowFilter) inside the 2012 R3 Intel Media SDK, but i can't really connect it in GraphEdit
Also it seems it only takes a combined bitstream, not seperated streams.

That's true. And the way is to try to remux two streams into .mvc one. As well as Intel MVC decoder, original ldecod binaries also support .mvc format, so the alexpk's work was based on remuxing two files into one. I haven't studied h264 ("annex H", I guess; Intel MVC decoder & ldecod supports only "annex B") well to do so.
And if someone do so, it will be absolutely legal.
