Any sound and mostly dts & dts-hd to ac3

[fits79]

Is there any newer program that do that?
Convert all the sound types into simple ac3-stereo?
Without change at all the quality of the video.


If there is any program that it doesn't need to much powerful pc please tell me which is the program.


Thanks

Try clever Ffmpeg-GUI.
Fast & easy.

[fits79]

Thanks for your suggestion but there two problems


01. It can't do a full folder of video files.
02. This program simply convert and extract the audio into the type you choose. Doesn't muxing it back to the mkv file

01. No
02. After the dts to ac3 conversion click multiplex, the converted new ac3 stream is shown in green, deselect the original dts stream, click multiplex.
Done.

I want a program that do all these automatically so i put one folder with video files and convert them all to mkv with ac3 sound.
And this program importunately don't do that.

Batch file with ffmpeg:

for %%A in (*.mkv) DO (
    ffmpeg -i "%%~dpnxA" -c:v copy -c:a ac3 "%%~dpnA.ac3.mkv")
)

[fits79]

So now there is any easy to use program like makemkv to convert all audio files into ac3(multi channel or stereo)?
If there is please tell me which one is?

Makemkv doesn't do any converting and there's no program that's easy to do what you want.

You should be able to do it with MeGUI's OneClick encoder.

When you open it, if you click on Config next to the One Click Profile dropdown box, you can configure it with your preferred settings and save that as a preset.
The One Click encoder can open a single file, or a folder.

Or if you want a more simple GUI, you can configure AnotherGUI to batch encode with ffmpeg.
An ffmpeg preset for AnotherGUI would look like this:

-i "<FullSourceFileName>" -c:v copy -c:a ac3 "<OutputPath><OutputFileName>.mkv

And how is the program supposed to know which stream you want to convert to ac3?

[fits79]

I choose which stream i want to convert.
But even at mkv files with only one and only audio stream still doesn't work so......

I don't know what that error means. Have you used MeGUI before or was this the first time?
I rarely use the OneClick Encoder so I thought I'd check it's working properly. My test job finished successfully.
I've attached my MeGUI log file below. It might help you find the cause of your error, if you can compare your log file to a log containing a OneClick job that completed successfully.

I included the text for a new AnotherGUI preset in my previous post. You'll have to create an ffmpeg preset for AnotherGUI yourself, and add the text as the command line. It must be added to the First Pass section of the preset (as the screenshot shows).
