I am creating videos showing step-by-step instructions for navigating a web-portal. I am using text-to-speech audio for each step. The final "course" is 30+ slides with audio. I am then publishing as a video.
When I play the video back, the volume of the text-to-speech instructions is getting progressively louder as the video plays. It does this gradually, so you do not notice at first, but if you scrub back to the beginning and then to the end, and compare volume, it is very noticeable. I have tried checking the "Set the same volume level for all audio" box, and it doesn't help. And all the audio is text-to-speech, so it should all render the same anyway!
Thanks for reaching out, and great call to open a case! It looks like you're in good hands with our Support Team, and Renato is testing your file and will get back with you soon.
I'll follow along as the case progresses and share any relevant insight here!
Was this issue resolved and if so, how was it fixed? I am having a similar issue when I publish my Storyline 360 course as a video. The audio is getting progressively louder for no apparent issue. I published another course to video without issues but this one is a problem. I've saved it as a course with a different name and deleted and readded the audio several times. Can you help me?
Thanks to Jason's help troubleshooting this issue with our team, we logged this as a bug. We see this issue specifically when audio is inserted into slides that are created from a screen recording. The volume increases when published for video output.
I've added your comments to our current report! When we have an update, we'll share it in this discussion.
Hi Lauren! Just to let you know that this was not created from a screen recording. I used multiple images and text boxes with animations and was intending to turn it into a video.
Thanks for clarifying! Are you comfortable if we take a look at your file to confirm if this is related to the bug? You can upload it to us by using this secure upload link. We'll reply to you after reviewing and then delete the file after troubleshooting. Let me know if you have additional questions!
Thank you for sharing your file! It actually looks like this issue was related to file corruption. I've exported the audio files, imported them into a blank project, and then copied the slides into the new project. You might need to customize the story size, but I've published the course to video, and the audio volume is consistent throughout the project. I'm attaching the updated file.
I am getting the same issue when publishing step mode screen recordings from Storyline - the volume increases as the video progresses.
The audio has been generated with TTS. The audio option "Select the same volume for all audio" is selected and the audio and video quality are set to "high".
I have the latest update Build 3.47.23871.0. I've been producing video from screen recordings for some time and don't remember seeing this issue until recently.
I can provide a Storyline file and example published video if that would help (subject to client approval).
Thank you for sharing these details! With Pat's project, I was able to export the audio files and then import them into a blank project. Lastly, I copied the slides into the new project.
Would you mind trying these steps? If you still see an issue with the volume, it would be helpful to look at the .story file.
I'll give this a try one of the scenes in my project (I'm publishing scenes individually). But the project I'm currently working on has 140 step slides. It would take me hours to export the audio, copy slides to a new project and then re-add the audio. On top of that, I guess the audio would no longer be editabe TTS once exported as a WAV file?
I've tried that and it didn't work, unfortunately...
First I tried exporting the TTS audio files in mp3 format as you suggest and then added them to the same project to replace the TTS files (actually, I just hid the original TTS files on the timeline). But the audio still increases when published as video.
Second, I created a new Storyline project, then copied the slides from my original project and then replaced the audio with the exported mp3 files (leaving the TTS files on the timeline as above). The audio still increases.
Finally, I deleted the TTS files from the timeline in my new project, so that this now only has the imported mp3 audio. The volume still increases.
Thank you for continuing to troubleshoot this issue with us! I'd like our Support Engineers to continue investigating this snag with you. I've started a support case on your behalf and sent you an upload link if you're comfortable sharing the affected file.
For info... I have been working with Articulate support on my file and they have confirmed that this is a possible bug, which has been logged with the development team.
In the meantime, you could try "normalising" the audio after publishing to video, using a video editor or this free online utility - https://www.video2edit.com/compress-video#su=d444f706-3665-4f2f-9734-6831cf9c4137 I've tried this and it worked for me, although the audio ended up more distorted, so maybe worth publishing at max audio quality from Storyline.
I'm happy to return to this discussion with some great news 🗞
We've fixed the issue you reported where the volume of audio increases if inserted to a slide created from screen recording and if published for video output.
I have just updated Storyline to the latest version (Build 3.50.24668.0) and did a test publish to video. The problem is still there (i.e the audio volume increases) and there is no mention of a fix for this in the version history.

Thanks, Lauren! I appreciate the help.
I'd appreciate it if you could delete the story file now.
Hi Pat!
Absolutely, happy to help!
I've deleted the .story file from my post. If you'd like to delete the .story file from your post, edit the post and delete the attachment.
I am getting the same issue when publishing step mode screen recordings from Storyline - the volume increases as the video progresses.

Greetings, Dayn!
Thanks for writing in! We're having trouble recreating the issue Lauren mentions in Storyline 360 Update 47 (here's how to update the app):
Are you seeing the volume increase on the latest update or another version of Storyline? I'm happy to troubleshoot further!

Hello Everyone!
I'm happy to return to this discussion with some great news 🗞
We've fixed the issue you reported where the volume of audio increases if inserted to a slide created from screen recording and if published for video output.
Be sure to install the latest Storyline 360 update (Build 3.50.24668.0) to take advantage of all the recent features and fixes.
If this happens again, please let us know! Or you can work directly with our support engineers here.
That's great news. Thanks for the prompt fix!
Hi Becca.
I have just updated Storyline to the latest version (Build 3.50.24668.0) and did a test publish to video. The problem is still there (i.e the audio volume increases) and there is no mention of a fix for this in the version history.
I can supply a demo published video if required.
Thanks, Dayn. It looks like we have an open support case with you as well, so I'll update Eric and our team can look into this again.
