Audio and Video out of sync when using Seekbar
Jul 29, 2014

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.

So glad to see this, thank you!
Hello,
I'm assuming there hasn't been a solution for this? I have the latest storyline update (9: 1605.1919) and have the same sync issues when using the seekbar. My course consists entirely of interactive videos so this is a real issue.
Hi Darren,
Did you see Leslie's reply on the previous page?

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.
You'll also find it documented here.
Oh, really? I'm not having that problem anymore with the latest update.
I did put a video together on how to fix the problem by adjusting
keyframes, if the updated absolutely isn't working for you, for whatever
reason.

Hi Ashley,
Yes, I saw Leslie's post from the previous page and I have the latest update of storyline. However, the issue still occurs on one slide.
Dan - Thanks, I saw your video before posting as well. It looked promising but Premier keeps crashing on me before I can even do anything so I cannot adjust the keyframe through there. :(
Darren, Give Cyberlink PowerDirector 14 a try. It has a trial and is really stable.
Hi Darren,
We'd be happy to take a look to see what may be happening - and the fix put in place will work with your content as described:
We worked around the Flash limitation described above by forcing the seekbar to line up with keyframes in your videos.
As a result, the seekbar may not always stop exactly where you stop when scrubbing through a video in Flash output. The seekbar now stops at the nearest keyframe in your video to ensure that the video is always synchronized with the slide.
So that may be what you're experiencing and running into on one slide?
You might try Camtasia as a means to publish your video files with keyframes added every second.
Thank you all for your responses. What I'm actually noticing now is that it's not the audio that is out of sync, but my highlight boxes and callouts. The audio seems to sync well, but the call outs are not lining up only when you toggle through the seekbar. They are aligned if you allow the video to play on its own.
Hi Darren,
It may still be connected to the key frame issue - and it's something that our team will still be happy to take a look at. Let me know if you send it along to our Support Engineers as a part of a case.
Thanks, Ashley. I have submitted. I will update as soon as I hear more.
Thanks Darren - I see your case (# 00812355 for my reference) and I'll follow along as well to keep the thread updated.
I am experience this same issue. My video is 600 seconds and I am having issues with the seek bar. When I stop the video and try to add a shape layer it gets out of sync. I have to start the video from the beginning to see if everything in aligned again. Very frustrating.
Hi Johnny,
This forum discussion is a bit older, and as such it seems Darren was using Storyline 1. That issue was reported to our QA team and still remains an open issue. Are you using Storyline 2 or Storyline 360? If so, can you share a copy of your .story file with our Support Engineers here so that we can double the behavior?
Hi all !
I'm poping in 3 years later !
I uploaded a video on a layer
- the video starts with the layer's timeline
- there is only the video in this layer
I'd like to avoid showing the video controls below it and use instead the built in timeline.
Unfortunately, they are not synced and i can't figure where to do so....
In other words, when forwarding or backwarding (if this word exists) using the seekbar, the video just keeps on playing....
PS : i use SL 3
Thanks !!
First I’ll state the obvious (just in case), If the video is in a popup layer, then you’ll need to turn on the seek within the popup layer properties. If you are experiencing a true synch issue after scrubbing, be sure to use 30fps videos only. 29.97fps vids tend to be the cause of the synching problems.

Hi Jean Guy
Thanks for the prompt answer, and you had it (with an extra non obvious trick, at least for me ^^ )
I made 2 mistakes :
start the video with a trigger "when the timeline starts" instead of chosing "automatically" in the video option in the top ribbon
leave the seekbar option on "automatically decide"
eventhough it showed like it was working, puting it manually on "yes" made it work for good
Cheers all
Have a great day
Glad to see that Jean-Guy was able to assist you here Tim. Thanks for popping in with an update.
I realize it's been a while since anyone's posted to this, but I'm on 360 and I'm not able to get my recorded audio to sync with the seekbar. I've added a trigger to the audio and set the "yes" option on the seekbar slide properties, but when I try to skip around using the seekbar, the audio keep playing and doesn't move forward or backward to the point selected on the seekbar.
This is a tutorial, so I want to keep the seekbar option open so my users can skip around and play/replay as many times as needed.
It seems to be an issue with media embedded on layers, I'm having issues with mp4's not scrubbing when they are on a layer. They are fine in the main timeline.
I have audio on both the main timeline and some layers and the result is the same; the images will scrub back and forth depending on where I click on the seekbar, but the audio keeps going.
Hi there, Sam. I was able to scrub through layer audio in this sample. My settings were to pause the timeline of the base layer, and to set the seekbar to allow seeking.
If you can share your .story file with me, I'll have a look and see what's up! Use this link if you need to keep it private.
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!
