Bug with Merge Video - Only exports audio in left channel

I wasn't sure the best place to submit this but I noticed a bug with the MERGE VIDEO function in Adobe Express.


The .mp4 files generated only provide audio in the left channel - with nothing in the right.

 

This is too bad since this is such an incredibly useful tool.

Hi @DanBennett_SmithCollege, Do not worry, we will check this for you. Would you mind being more precise on this bug? What happens when you merge the video? Do you get any error messages or pop-ups? Also, check if this is a video-specific issue. We do not see any attached screenshots that we could refer to. It will be great if you share the screenshot or a short recording of the issue so that we could reach the root cause or report it to our engineering team. We will be looking forward to your response. Thanks ^Manmeet

Not sure how to describe it more clearly.
When I use the Merge Video tool, the final mp4 file that I download from Adobe Express has stereo audio and only has audio in the left channel. 

No error messages or pop-ups.
I have double checked this with several videos from different sources and always get the same result. 

I've attached a test video made from two Zoom recordings - both with Mono audio.
As you will hear, the resulting stereo .mp4 file from Adobe Express has only audio in the left channel. 
And you can clearly see in the screenshot when bringing the file into Premiere it only has audio in the left channel.

 It's typical for audio files to have sound recorded on either the left or right track, depending on how the recording was done.

The audio channels need to be checked on https://www.movavi.com/video-compressor-online.html or other video editors. It's typical for audio files to have sound recorded on either the left or right track, depending on how the recording was done. Both songs can play simultaneously using the audio effects Fill Left with Right or Fill Right with Left. Even if your audio clips are mono or stereo with both L and R channels and everything appears to be working as it should in your timeline, something could still go wrong when you export. Check out if anything has changed in your audio tab since you last shipped.
