Audio randomly changing volume in slide exported to video format

Dec 19, 2023

When a slide is exported from Storyline 360 into video format, the audio volume changes at random in the exported video.

Tried to fix the issue by removing compression for the audio track/file in the slide & unticking option to set all audio to the same volume in the publishing panel. Nothing seems to fix the issue.

See attachment of how the exported video/audio waveform looks like (blue) versus the original audio waveform with the correct volume (green). There is a noticeable increase in volume in the exported video.

Has anyone experienced this? Have you found a solution to it?

Hi Reka, 👋

Thanks so much for reaching out! Happy to help! I am sorry to hear you've run into this snag when Publishing to Video

I have a few quick questions to better understand your setup. 

Does your video currently have narration included? If not, do you have audio included in the slide separately? It appears that it's included in the video from your screenshot, but I wanted to confirm. 

When navigating to the Publish window and selecting the Video publishing option, you'll see a section for Audio Quality. Could you please share a screenshot of your current settings?

It would also be helpful to take a closer look at your .story file. Feel free to upload your file to this thread or privately in a support case!

Looking forward to hearing from you! 🎉

Hi Luciana,

Thank you for the quick response!

So the process used by the team is the following: generate an AI narration using Murf -> download narration from Murf (audio volume is ok) -> import this Murf narration into Storyline -> add narration and images onto slide -> export slide as Video (no compression, no volume levelling selected) - > the video exported from story has a fluctuating volume.

The image that I attached to my first comment called "waveform_volume..." is just a comparison to show how the waveform from the exported story video compares to the original Murf generated narration. Something seems to go wrong with the audio levels during slide to video export.

I attached a screenshot of the timeline and the publish settings panel showing the audio quality as you requested.

Thanks again for your help! :)

  • Could you please share more details about the type of media you've included in your course on the slide you published to video?

(For example: Screen recording, background audio, imported.MP4 file, or another type of media.)

If you can also share the .story file and published Video, it would be very helpful. Feel free to upload to this discussion or share with us privately in a support case.

Looking forward to hearing from you!
