UniConverter Conversion MP4 to MP3 question:

[Xogroroth]

Avē Imperātor, moritūrī tē salūtant:

I have UniConverter, Had the MP3 set up in the starter window.
Added files (a measly 386 MP4's which I need to "extract" the music off, saving it into MP3).

Once files were loaded, hit the "Output Quality" ... and I saw, I could not change the needed changes:
I went to "High Quality", sure ... but the required Format option ... not there.
UniConverter seems extremely limited in this (48KHz max, although my system can handle a few Hz more, I am missing the better ones here despite the abilities of my system).
As I want to extract the music from the MP4's in 24bit, 192KHz, (yes indeed: 24bit, 192KHz, it is not a mistake) but do not get these options, areth I teh screwzorred?
Hope not ...

Or did I miss something?
48'000 is not even remotely what I need I fear.
Is there a way to overcome these limitations, please, and how do I do that?

Thank you very much aforehand:

Xog.

try this

ffmpeg -i test.mp4 -acodec pcm_s24le -ar 192000 output.wav

I'm no expert but...

48,000 would be the sampling rate, not the bitrate. 192,000 sounds very much like the bitrate.

output.wav

They want MP3s.

No, the command is correct, but the output is a 24 Bit pcm(wav) file with 192kHz.

This board needs a "Thanks" button.

Thank you very much, good sir.
Where do I put this code into, please (Apologies, noob here ... . )?

+ Thanks.

I am assuming that you are using the windows operating system.


download https://www.videohelp.com/download/ffmpeg-6.0-full_build.7z


extract ffmpeg.exe from the above downloaded zipped file and paste it into the directory which contains the 386 MP4's which you need to "extract" the music off.


With Windows Explorer displaying the contents of the directory in question, click once on the address line to highlight display line and then type cmd


This will execute the windows cmd.exe program and it will be set up for the correct directory.


Now copy, paste and execute the command.


ffmpeg -i test.mp4 -acodec pcm_s24le -ar 192000 output.wav


you will need to rename test.mp4 to whatever you have already named it.
