No audio after downloading Big Blue Button video

[Terry-AnnNelson]

I want to use Big Blue Button to record my screen and give student feedback. The problem I am having is that I can playback the video just fine after the recording ends—video and audio are perfect.

However, when I download it, the audio goes away.

Please help.

Hello @Terry-AnnNelson ...

I am not sure of an answer for you, but I would like to bring @ffdixon into this conversation in hopes that he will be able to help answer your question. Good luck to you!

Hi Terry,

I am the product manager for BigBlueButton. While I work at Blindside Networks, the company that provides hosting for BigBlueButton to Instructure since 2012, and can't speak on behalf of Instructure, I can respond to your question.

You are using the Free Tier of BigBlueButton, which means the recordings are not single video files.  In the Free Tier, there are actually two media files: one for presentation and one for screen share.  The presentation file has the audio track. That's why when you download it, it doesn't have any audio.

If your interested in having a single .mp4 file of screen share + presentation + audio, you could explore upgrading to the Premium Tier, which gives you permanent recordings as well (you don't need to download them).

To explore upgrading, just reach out to your CSM.

Is there a way to download the audio separately?

Hi Colin,

> Is there a way to download the audio separately? 

I believe in the presentation recording format, both videos are visible.  One video is for the webcams and audio, the other is for screen sharing.  

The webcams + audio video file is in the upper left-hand corner.  If you right click and choose "Save video as .." it will come down with the title "webcams.m4v"
