Problème de son avec une vidéo

Hello Cyrilou, 

Thanks for sending along your video file! I appreciate you sharing that this is only occurring with this specific video file when viewing your project in Chrome and Edge. 

When testing your file, I was able to maintain the original audio quality of the video by turning off video compression. Here's how: 

1. Select the Video: Click on the video placeholder in your Storyline 360 project.
2. Go to the Options Tab: Navigate to the Options tab on the Storyline ribbon. 
3. Adjust Compression Settings: Click the Compression drop-down list. 
4. Choose None: Select None to turn off compression for your MP4 video. This will ensure that your video maintains its original quality. 

I'd like to walk you through my experience testing and modifying the video properties for your reference.

I hope this helps! If you are still having trouble with the video volume, I'd be happy to take a closer look at your .story file in this thread or privately in a support case. 

Looking forward to hearing from you!
