HandbrakeCli stereo output on movie file

Hi there

I have a requirement to output stereo in an H.264 file from a stereo audio source.

The original move has 2 channels of audio, and the output seems to be being made into mono by default, regardless of any switches I add to the parameters.

Here is my current command:

"C:\Program Files\Handbrake\handbrakecli.exe" -i "C:\Transcoding\Input\ORIGINAL INPUT FILE.mov" -o "C:\Transcoding\Output\ORIGINAL INPUT FILE.mp4" -e x264 -b 128 -B 128 --width 352 --height 288 -a 1,2 --mixdown stereo --drc 2.0

But it's still coming out in mono - does anyone have any ideas? Thanks in advance!

Hello butterhook,

If you want to get stereo sound try this successfull cod that I check and get stereo MP4 file:

"C:\Program Files\Handbrake\handbrakecli.exe" -i "C:\Program Files\Handbrake\sample_iTunes.mov" -o "C:\Program Files\Handbrake\sample_iTunes.mp4" -e x264 -b 360 -B 128 -w 640 -l 480 -a 1 -6 stereo --drc 2.0

The source MOV file you can freely download from Apple's site:

sample_iTunes.mov

The converted sample_iTunes.mp4 file has next characteristics:

In VLC:

Hi there
We found another way to do this not using Handbrake - using FFMpeg. Thank you for your input though!
