Publishing Storyline as MP4 file

Hi all, I created a module in Storyline with mobile-sized videos and call outs. When I published as MP4, however, the final video plays really glitchy. The video freezes and skips, which makes it unwatchable. I reduced the size when I saved and I even took out the call-outs I had animating in, but I still get the same freezing and skipping.

I searched the forum here and it looks like this was an issue three months ago. Just wondering if this has been addressed in a recent update.  

Thanks!

    I'm experiencing the exact same issue on a very large client project involving mobile-sized / vertical videos. The published MP4 has random freezes/stutters baked into the video. If I republish, the stutters are still there, but they appear in different places.

    I've done enough testing to know that it was an early January Articulate update that caused this to break. I am using the 12/17/25 version of Storyline to keep the project going. 

    Any help on this would be greatly appreciated!

    Hi ded2 and KeithKemsley,

    Thanks for reaching out about this!

    KeithKemsley, I see you've already connected with my teammates in a support case. We'll keep you updated on any changes. In the meantime, I recommend continuing to use version 3.107.35974.0 since it allows you to keep working on your project.

    ded2​ our team is currently tracking a bug where video output stutters or freezes when publishing a course for video. To help us determine whether you're running into the same issue, I have a few questions:

    If you're comfortable sharing your file, we'd be happy to test it and see whether we can reproduce the behavior. If you prefer, you can share it in a support case, and we'll delete it once troubleshooting is complete.

      I'll try the videos from the content library to see if it makes  a difference. The ones I used are from the client's source (storyblocks). At this point I don't want to roll back to a previous version since I had major audio skipping issues with Review and my LMS that weren't fixed until the latest release. So I'm kind of in a quandary. Let me try importing into a new Storyline file first and see if that works. Thanks!

    Hello Kelly,

    Thank you for your attention to this and working with ded2 on the same issue. :)

    I can tell you that for me and the other developer here, the following did NOT work:
    1. Importing to a new Storyline
    2. Using content library videos (that totaled 2min or more)
    3. Rolling back to anything later than 12/17/25.

    Thanks!
