Thanks for the new version!

Just a quick question: what exactly does "TrueHD Core" stand for? I don't seem to be able to find it in Dolby's own specs. In BDtoAVCHD I can see that opting for either TrueHD Core or AC3 640kbps yields the same video bitrate. Are TrueHD Core and AC3 640kbps comparable?

TrueHD tracks (AC3-HD) as DTS-HD self-contain a "core" track for maintain the compatibility with older receivers. The core track is a CBR normal AC3 (640, 448, ? Kbps) or DTS (768, 1536.. Kbps). It?s the same takes a separate AC3 640 Kbps track or a Core part of TrueHD (if core is 640 Kbps also)

But it is better to take the "core" 640Kbps to convert other track to 640kbps...

In the specs of Dolby TrueHD it says the TrueHD stream can contain a seperate two channel audiotrack, which will have priority over downmixing the 5.1 or 7.1 to stereo. I could not find any info about Dolby TrueHD also being able to contain a seperate AC3 multichannel audiotrack.

The specs say many things:
http://www.dolby.com/uploadedFiles/A...aper_Final.pdf
(But the truth is that it is not clear)

But I found this:

"So it seems that more and more people are getting into Blu-ray and are looking for ways to back up their collections and play them over the network via the PCH or one of the other streamers. With the new generation of HDMI 1.3a-compliant streamers we can even stream DTS-HD and TrueHD to compatible amplifiers -- however, not everyone has one of these streamers, or a compatible amplifier, or if they do then they may also have older streamers/amps around the house that they also want to play the movie on.

DTS-HD very helpfully comes with a legacy DTS core that the PCM will play out through optical/coaxial or HDMI or even downmix to stereo PCM, depending on what menu option you choose.

TrueHD doesn't work in quite the same way, but every Blu-ray TrueHD track comes with an interleaved legacy Dolby Digital (AC3) track that doesn't appear as a separate audio track to a Blu-ray player but is meant to be selected automatically by the machine if it knows that you've only got optical/coaxial. The PCH doesn't behave like a Blu-ray player in this respect, it just ignores the interleaved AC3 track and there is no way to get at it, whether automatically or manually..."

Original text:
http://www.networkedmediatank.com/sh....php?tid=14869

Conclusion:
Interleaved track ~= core track and yes! Dolby TrueHD also being able to contain a seperate AC3 multichannel audiotrack

Well, I'll just keep downmixing to AC3 640kbps just to err on the safe side. That way I'm sure the AVCHD will have playable audio, no matter what player.

Good evening everyone.

I noticed that when I select the forced subtitles, when it makes into these copies BD are activated for the duration of the film, so do not full but those are automatic.

Then I have problem, perhaps unique, I can not find the subtitles convicts in Van Helsing, if I leave everything default, turn on the wrong ones, referring to the director's commentary or other
if I try to select another subtitle file, you enable only those standing for the duration of the film.




I tried for two days helping with other tools, I'd give anything to be done, wonder if anyone has had this problem or if a solution exists.

Thanks for the program and that you constantly update it.

I have a question regarding the subtitles. Is there any way to customize the font style and size and so forth for them? On my backup I ended up with very small subtitles pushed to the bottom of the screen.

Hello Pistachio!

I have a question, i saw that you had now FAQ but i will ask you that questions.

Did you BDtoAVCHD is can build AVCHD with more than 1 languages?

If not, did it will be an future add-on that your planning to integrate?

Thanks!! Great app!!!

The only way to have subs in your AVCHD is when they're present on your original Blu-ray, or, when converting a MKV, when they're already muxed in with your MKV. Supplying a SRT, for example, is not possible.

I just tried using your program. Simple GUI I/F and very easy to use! And, I also like having the option to keep the HD audio track.

I'm trying to backup Evangelion 2.22 to a BD25 keeping the DTS-HD MA track at the "very slow" x264 setting. However, the final result came out to be 15.7 GB, and I was expecting something closer to 23.2 GB.

Is this normal?

Usually forced subs come in a separate track. However, in some BD (few) can come mixed in the same track as all dialog subtitles.

Perhaps this is what happens in this case. If so there is no way to separate them. One solution would be to get the forced subs separately and add them later with tsMuxer.

There is no option to change the format of the subs but usually not necessary. The position, size, color and font are taken from the original PGS track. If the Blu-Ray the letters are large and yellow in the conversion will look the same for example. Have you checked as are the original subtitles?

I mean burning the subs that are in the original bluray file into the actual video? That would be useful for me

Incrusted subtitles in video are not possible but forced subtitles (default on) or unforced (default off) YES.

It is more versatile to have the subtitles on a track to have them incrusted in the video... I think.

Perhaps with only an audio track needs only this size but do not know.

If you paste the BDInfo log of souce I can look if I see the cause.

Would be nice to have the option , specially if you want to view the resulting file on a program that doesn't support bluray forced subs.

Thanks

There is no option to change the format of the subs but usually not necessary. The position, size, color and font are taken from the original PGS track. If the Blu-Ray the letters are large and yellow in the conversion will look the same for example. Have you checked as are the original subtitles?
Yes, the subtitles on the source are in normal size, whereas the backed-up ones are tiny. I also tried multiple discs to see if it was just on the first one, but it was the same on all I tested.

@ hoju3508:

Well, these are my calculations:

Aproximate Bitrate = 25.000.000.000 x 8 / 6729 (1:52:09) = 29722 Kbps

Aprox. Video Bitrate = Bitrate ? Audio ? Subs ? Overhead(4%) =
29722 ? 2370 ? 180 ? 1188 = 25984 Kbps

And in your MediaInfo:

Quote:
Video
Nominal bit rate : 25.8 Mbps

So here is correct. The bitrate calculated by the program matches

But the real file has a different size and hence a different bitrate. In fact according to MediaInfo: total bitrate < video bitrate. This is impossible!

Quote:
Overall bit rate : 20.1 Mbps

I can only think of two things: The video or file is corrupted (or missing a piece) or x264 codec has ignored the bitrrate indicated in the command line.

On the other hand the x264 command line is correct:

Sorry I can not give a specific explanation but at least we know that the bitrate calculation is correct and the problem is after...
