Excellent! Being able to wrap your selection from top to bottom or bottom to top would be awesome. Appreciate your willingness to look into the other item as well and at least I've got a way to accomplish the same end result though it would be far more preferable naturally to have the one file play "x" number of times rather than what I'm doing now.

is it possible to have an alternate output with only the m2ts generated when you choose BD output.
after extraction from the iso, the generated m2ts for a movie only seems to work fine on my oppo103, even in 3D (i need to test it a little more by the way).

audio encoding options in mkv container

@jdobbs

Is it possible in BD-RB to apply the "audio encoding options" that were set under settings/setup dialogue to the mkv profiles located in alternate.txt? It would be great if these options would be available while making mkv movie-only encodes. I would prefer in my mkv movie only-encodes as well the settings which were set under "audio encoding options" to keeping the tracks intact.

Thank you in advance for your opinion.

Just keep the m2ts file and delete everything else.

Can be done by using a custom ALTERNATE OUTPUT profile

and indeed..sorry before asking than testing.
I could achieve what I wanted by using:

aBitrate=*
aType=0

Can you explain a bit what automatic (*) means?
What bitrate is it using for audio encoding automatically?
I assume it "uses" 640 kbit/s AC3 conversion on 5.1 & 7.1DTS/DTS HD tracks and 224 kbit/s on 2.0 DTS/DTS HD tracks and no reencoding at all (keeping the core) on the DD audio tracks with the bitrate under (e.g. 448 kbs) or equal to (Dolby True HD) that, right?

automatic is meant for DVD output, I believe. Bitrate would probably be 448 with AC3.
If you want audio tracks intact use aType=2, (for MKV and MP4 output).
If you want AC3 with a specific bitrate use aType=0
aBitrate=xxx where xxx is the bitrate you want
If aBitrate is less than 384 Then it will be down mixed to stereo
If you just want AC3=640 then enter aBitrate=640.

If you want, just tell me how you like to encode and I can help you create a preset.

Right, except "automatic" is for anything except iPod/iPad. It changes depending upon the type of output. Generally it would be 640Kbs for 5.1 AC3, unless you've chosen DVD output (in which case it would be 448Kbs).

Is it possible in an mkv container (like within a BD structure):

- keep the DTS core from DTS-HD tracks;
- keep the AC3 core from Dolby TRUE HD tracks;

Does "audio encoding options" have any impact on creating an mkv container or does it have it's own separated settings?

Your answers would be really appreciated.

Thanks for your reply.

I am currently mostly making HEVC mkv containers (thanks to jdobbs for the HEVC implementation) from my Blu-rays, so it is now a common situation to have both an eng DTS-HD or Dolby True HD track + a hun DD 5.1 track with a bitrate of 640 kbit/s to be reencoded. Generally, I would keep the hun track as it is (which is 448 kbit/s or 640kbit/s on the BD) without reencoding and the same I would do with the 640 kbit/s AC3 core for True HD sources. I would reencode the DTS HD track to AC3 640 kbit/s. This would be my aim.

Sounds like you want aType=0
aBitrate=640

I have been having trouble with audio on mp4 output, so thought I would take you up on your offer.

I have at least one mobile device that only likes stereo AAC audio tracks. It spits up blood on AC3. So I have been using the following preset:
[00039]
caption=BD to MP4, 1280x720, Stereo-AAC
vBitrate=2500
aBitrate=256
aType=1
vFormat=4
cType=5

This preset does provide AAC stereo audio but no matter what I set aBitrate to, it always comes out at about 164. I have tried 256 and 320, neither work. Is it because aBitrate does not work with AAC?

Thanks...

I don't use AAC so I have to assume it has to do with Variable Bitrate settings, and your program reporting an average bitrate.
If your mobile device is a tablet, try 128Kbps AAC.

I don't want a lower audio bitrate, I would like it to be approx 256. BTW, the problem mobile device is a windows phone, my tab handles AC3 just fine.

The 128 Kbps remark was only for space saving. What AAC encoder are you using?

I am not sure, I have ffdshow installed. I just use defaults. Am not sure how I would set an audio encoder.

By default it is FAAC. You can also use Nero AAC encoder. It is free, but cannot be redistributed -- so you'd have to download it separately to use it.

Is FORCED_SUB_LANG=s hiddenopt working correctly both by a general subtitle track that has several items which are flagged as forced and with a separated subtitle track that only has forced subs which are flagged as forced?

Thank you very much for the answer.

I just tried a quick test encode, it appears that the 256 k in your audio bitrate is the maximum and the 163-164 K is the average in a variable bitrate encode

Thanks for testing my presets. I guess what I am seeing is an average but that average does not seem to increase if I increase aBitrate to 320. Oh well, not a big deal.

The low average bit rate might have to do with the complexity of the audio track. Different tracks might have different average bitrates, some higher some lower
