Audio and Video out of sync when using Seekbar
I have a number of different courses where I have recorded video using Storyline. I have then exported the video, converted it to an audio file, edited the audio with Audacity, and then inserted the audio file back into the slide. When I play the video everything works fine until I use the seekbar. If I try to use the seekbar the video jumps to the right part but the audio doesn't jump with the video. The audio just keeps on playing. I'm sure there is an easy solution to this but I'm a new user and don't know what it is. Please help Storyline experts.
Thanks.

WOW! The only difference I see between your file and mine is that you don't have a trigger for your audio and I had mine set to start at the beginning of the timeline. I never thought to try that and it looks like this made all the difference. Thank you!
Hello All,
I was struggling with keeping my separately recorded audio and video in sync after dragging the seek bar. I am using Articulate 360, and at first I had the video and audio in the same base layer. I set the audio to play with a "play media when timeline starts" trigger. The video aligned with the slide's seek bar but the audio fell out of sync. Then I found this link:
https://articulate.com/support/article/seekbar-doesnt-control-triggered-audio
It said to place the audio in a separate layer without any triggers, remove the play media trigger from the base layer, and replace it what a "show layer when timeline starts" trigger to play the audio on the newly created layer. After taking these steps, the audio was perfectly aligned with the seek bar, but the video played on leaving it all out of sync.
This next step did the trick!! I cut the video from the base layer and pasted it into the layer with the audio. I left the base layer blank with no audio or video. It only has the trigger to show layer when timeline starts, and it worked like a charm. Perfect pause/play and seek.
I hope this helps someone out there!
Hi - Storyline is such a user-friendly product. I really appreciate this support community!
Unfortunately, I'm still encountering this bug in Articulate 360. When triggers and audio/video are on the same slide, synchronization is compromise after moving the seekbar.Can anyone please help with a solution for this issue in 360? It is critical to my enterprise's time-sensitive solution for a major training initiative.
Thanks so much!
Hi Pat,
The community is a supportive bunch and I'm glad you're finding good help here! I see that you've connected with our Support Team on this snag, so I recommend following up with Mark on uploading your file and sharing details to get to the bottom of this!
He'll be able to troubleshoot your file and share some further guidance!
Hi Pat, my experience with this issue has been the fps of the movie imported. If I import anything other than 30fps I end up with synch issues. Even if the video is 29.97fps. Whenever I get a video that doesn't match I do a conversion in aftereffects using interpolation.
Hope this helps and good luck.
Hello. I am here in 2025 experiencing this same issue. All seems to work fine in storyline preview, but when I upload to review or to an LMS (I have tried multiple) then intermittently the use of the seekbar causes animations and audio to go out of sync. I find the intermittent nature of this very odd. I have had to tell my users to refresh their browser if it happens because it is so inconsistent.
Is anyone experiencing this in 2025?

Thank you for the link Jean. However, I don't think this solves my issue. My audio is AI text to speech and the visuals are images/graphics that are animated. All embedded in timeline. Hopefully someone can explain this particular issue, especially as it occurs so intermittently.
