Audio gets louder with time

May 17, 2021

Dear team,
we're experiencing the following issue: the volume of audio increases when published for video output. In this project, text-to-speech audio is inserted. The exported video starts quietly and gets louder with time. The audio option "Select the same volume for all audio" is selected and the audio and video quality are set to "high".


Has anyone experienced a similar issue and knows how to fix it?

I wanted to add to this thread that I am experiencing the same issue and my video is not from a screen recording. I inserted a professionally created VO audio file MP3 over my storyline build, the audio in the file is perfect on its own and when played while authoring. But every time I publish to video it gets louder and louder throughout. I've played with a few settings and it does it every time. Would love to know what is causing this. I'm going to have to screen capture the module in preview mode in order to create an MP4 without this issue.

Hi Rebecca, and welcome to the E-Learning Heroes community! ✨

I apologize for the issues you are experiencing with your audio getting louder when publishing to Video.

It would be helpful if you could share your audio file with us either publicly here, or privately in a case so we can investigate further? We will delete it from our systems when troubleshooting is complete.
