Select and mix individual audio tracks of source file to one stereo track of output file?
Feature details
Hello,
As a video editor working for a tv station, every day I have to create mp4 preview files for trailers, spots and sometimes whole shows. We export to .mxf files (XDCAM HD422 OP1a) for broadcast. MXF files contain one video and eight audio tracks. According to requirements, the files we deliver should have all audio mixed in the first two audio tracks: Audio track 1 for the left channel Audio track 2 for the right channel The other six tracks (3-8) are kept empty.
I used Vidcoder to make an h.264 mp4 from such files, and realized that the following always happens: Vidcoder uses by default only the first audio track. When I tried to select the second audio track too, I couldn't find a way to mix the two of them to stereo. When two audio tracks are selected, Vidcoder creates an individual audio track for each one (like having a second language, or a commentary track, that can be selected via the media player).
So, my question is this: Is there a way to select two audio tracks from a multi audio track file, and mix them to one stereo track in the final mp4 file? If not, could you please consider implementing this feature?
Here is an example, hopefully to make it more clear: As a source file, I have an mxf with one video and eight audio tracks. I need to make an mp4 with just one stereo audio track, like this: Input audio track 1 --> Left channel of output file Input audio track 2 --> Right channel of output file
Currently I have to use another program to do that, but I really like to be able to use Vidcoder for all my conversions to mp4. Thank you very much in advance, Xenos
VidCoder is a video transcoder, and not an editor/mixer. It's based on the encoding engine of HandBrake, and they've stated that their project scope doesn't include video or audio editing or mixing. Sorry! You might be able to automate some of the work by writing a script that uses the VidCoder CLI to queue up encoding jobs.
Thank you for the quick response. It's a pity that even a basic audio mixing function is out of their scope, of course t's a great tool as it is now, but it could become more integrated. Honestly, I get better (and faster) results with Vidcoder (HandBrake) than with some "professional" tools. I test every transcoding software I can get my hands on with videos that contain "difficult" stuff to handle like sea waves, clouds, gradient sky, fast motion etc. After testing Vidcoder, I stopped using the (paid) software I had been using for years, at least for delivering h.264 and h.265 mp4 files. Thanks again.
