Inserting video - seek bar not working accurately

Feb 18, 2016

Hi Storyline team, I am creating a video based learning module.

When I insert a video from file and use the seek bar, I've noticed that the seek bar functionality in Storyline doesn't match up with the video. If I move the seek bar during the published view, the video timeline and seek bar timeline gets misaligned. What happens is, the slide ends up getting cut off, and the slide advances too soon.  The video and seek bar stay synced if I do not touch the seek bar.

Can anyone suggest how to ensure the video and seek bar stay lined up?

Hi Chris! Thanks for sharing your experience as well as your .story file for us to take a look.

A similar report has been filed with our QA Team to look into this issue. I will add this forum thread for both user awareness and so that we can update you when applicable.

The only workaround we are aware of at this time is to either remove the seekbar or make the seekbar read-only to prevent this issue.

Hi all,

I wanted to provide an update here, as Storyline 2 Update 8 was just released, and included a number of fixes which you can see in the release notes available here. The item you all may be particularly interested in is how it fixed an issue where a video would no longer be synced with the slide's timeline after using the seekbar to scrub back and forth through the video. You can download the latest update here, and after downloading and installing the latest update you’ll want to republish any existing content to ensure that the updates and fixes are applied.

Let us know if you have any questions, either here or by reaching out to our Support Engineers directly.

So...I am experiencing this same issue with the seek bar when I preview a published course.  I am current on my software updates.  

I have inserted a GoToWebinar proprietary file converted to MP4, and then due to the frame rate issue with GTW, the file was re-encoded to run at the proper frame rate.  See this thread in case any of those details matter to the below. (

I'd like to allow the viewer to run forwards and backwards in the video, but audio/video does not stay in sync.  Another post mentioned that video published within Storyline uses progressive if you play the video, then start jumping around using the seek bar, and the video is not completely not downloaded yet, I would imagine it would get out of sync!  Is there some setting, some other file format, that I should be checking or using?  I don't want to turn off the seek bar all together.

The .story file is employee handbook training, so unfortunately it is not something I can attach for troubleshooting.

Any updates on this bug?

I am trying to use videos in SL 3, but am having a very difficult time with the video 'timeline' and the slide 'seek bar' not matching up. 

I will post a new thread in just a moment with more detail, but since it is related, I thought I would start with checking on an update.

Thank you,

Ashley Kingon

Hi Ashley and welcome to E-Learning Heroes :)

Thanks for reaching out and sorry to hear that you're having a difficult time with your seekbar.

It looks like this thread is a bit dated and the issue was reported for Storyline 2, which we have a similar issue for Storyline 3 reported as fixed in Update 2.

I found your new post here, so I'll dig in a bit deeper there to understand what you may be experiencing.

Hi, Titus. Really sorry you're also having some trouble with the seekbar – I'd love to help out!

Are you dragging/clicking the seekbar after the video has ended, and is the timeline longer than the video length? I see a logged issue where our team is looking into the following behavior: a video on a slide will replay from the start when touching the seekbar after the video has ended and if the timeline is longer than the video length. Let me know if that matches your set-up!

If it's different, would you be willing to share your video or .story file with me so I can take a closer look?

Katie Riggio

Really appreciate the confirmation, Titus! I've attached your experience to this bug's report, and I'm really sorry again for any headaches. The current workaround for this is to have the video and timeline end at the same time – fingers crossed this works for you in the meantime while our team digs deeper.

Thanks again for bringing this to our attention! You're in the right place, and we’ll post all updates here once we have them! Klingler

Hmm... after reading more closely, ours might be different. It's not about the timeline and video being different lengths, it seems to happen to us now on all videos no matter the timeline. Any attempt to scrub causes the video to restart despite the new seekbar visible position. Is this the same or a different issue? Do we need to report another way?

Hi Steve,

Thanks for popping in with some clarification on what you're seeing.

Are you seeing this issue when clicking on the video control seekbar and viewing the HTML5 output? If so, we have this reported to our team and the only action I need from you is a confirmation so that I can attach this conversation to the report.

A workaround is to enable the player seekbar and use.

Hey Steve,

Sorry you're running into this problem! Let's see if we can narrow this down.

First, are you on the latest update of Storyline 360? To check, click the Help tab, then click About Storyline. You should see 3.17.16188.0 in the bottom-right corner. 

Let me know if you're already on that version, and we'll keep digging! Klingler

I just happened upon this as I was about to report it again - must have missed the notification advising of replies after my post. Sorry to leave the conversation hanging.

We are still having this problem when publishing to HTML5 or xAPI. We have faithfully installed each update as they become available and it's still happening to us with 3.19.16600.0.


If it helps, we always publish with "Formats:" set to "HTML5 Only" due to client requirements.

Using the video player seekbar instead of the slide seekbar is not desirable because of how they differ. A fix to the slide seekbar is the desired solution.

Hi there, Steve.  We're seeing an issue where if the timeline of the slide extends beyond the duration of the video, clicking the seekbar restarts the video rather than scrubbing the video.  The only workaround we've identified is to have the video and the slide timeline end at the same point, if possible.

I've updated the impact of this issue in our documentation.  We'll post any changes here! Klingler

We make sure that "Show Always" and "Show Until End" are both unchecked, make sure the video (mp4) is pushed all the way to the left, and then scroll to the end of the timeline and drag it left against the end of the video. The problem still exists. Is there something else we should be doing?

Perhaps related. On several slides our triggers that were tied to end of slide timeline stopped working. We had to either move them to end of media timeline, or duplicate in both places to get them to fire reliably. Klingler

Hi Alyssa. I sent the project files and example output this morning in response to another thread. I assume you can access it but if not I will upload again. Note that the seekbar is set to read-only to manage the issue but if you change that back and republish you will see the issue. Just open the module and click the next button a couple times for an example (slide 3.2).
