Audio only conversion

Postby WolfMax » 24 Nov 2009, 12:43

Hi

I'm trying to convert a mp4 video with ACC audio track to mp4 video with AC3 audio track but can't work out how to do just an audio conversion which leaves the video intact. The ACC audio is 5.1 channel which i want to retain and obiously I need to have the converted audio in sync with the video.

Any advice would be appreciated.

Cheers

Hello and thanks for your question

You must do this in expert mode , so go to expert mode and open audio tab to do it manually

enter your settings and check box do not encode video

To do it with a profile , load the following profile in your subdirectory profile located in the quickmediaconverter install directory.

Load the profile from expert mode clcik on the audio tab to verify and press convert ,

Here is a video tutorial about profiles [/url]

I also join a profile to help you do that

Good luck have a nice day

Hi

Thanks for the profile, I can see how it is supposed to work however when I tried to use it, it gave me an error asking me to "First Select a Conversion Format" and highlighted the 'Format' drop down in the Video Options Tab. Should I select something and if so what? As the selecion list is a little confusing having what appear to be formats and file extentions for both Audio and Video.

Thanks for the help so far, it is appreciated.

Cheers

Ps. I'm using the 3.8.0 beta version as I still haven't got 4.0.0 to work yet

yes just make sure (in the audio tab) that the "do not encode video" is checked activate mp4 format in video tan and the button must stay on red (off)

Hi

Don't get me wrong as I really do appreciate the help but that last post was just confusing.

I can only assume that "(In the Audio Tab) that the 'do not encode Video'..." you were actually refering to the Video Tab. But the last bit about the button being red (again I assumed Video Tab), doesn't work as I get an error:

"Error [[mpeg4 @ 009B29C0]timebase not supported by mpeg 4 StandardError while opening".

Using the profile posted above, in the Audio Tab I changed the Audio bit rate to 256k and the channel number to 6 (as using '1' causes "Error [ Stream #0.1(und): Audio,aac 48000Hz, 5:1Resampling with Input Channels greater than 2"). In the Video Tab I set the format to mp4, checked the 'Do not encode video' box and set the 'Red' button to green.
The convertor worked and created an mp4 file, only the audio worked ok but there was no video.

I'm stumped

Cheers
