Audio and Video out of sync when using Seekbar

Hi Bernard,

Sorry if I wasn't clear about the answer to question 1. You will want to republish existing content once there is an updated version to correct the syncing problem. There is not (that I know of yet) an "updater" similar to what we've been able to do for the issue with iOS9 that goes and updates code within the published output. 

I was speaking with our team the other day, and we don't have or share a schedule or timeline for updates (or even new products). The rationale behind this, is that during the testing phase and while we're confirming all the elements of any new update we may run into unexpected issues that could take longer or cause a delay. We don't want to promise or offer a target date as it may get pushed back and therefore we wouldn't be true to what was previously shared. I can see how this is perceived - but from my stance I'd say it's the lesser of two evils. 

I hope that helps clarify and if you have any other questions please feel free to let me know. I'll always offer as much as I'm able and if it's something I can reach out to our team regarding I'm happy to do so. 

Hi Dan,

Thanks for sharing the files and steps you went through here. I sent this directly along to our QA lead who let me know about the technical specifics of the sync issue to see if they're able to take a look at how your file is behaving as they continue testing the mentioned fix. I suspect as you surmised there may be a bit more "under the hood" that isn't included in my post above - the behind the scenes elements that we can't share, which I don't even know all of - likely because it's a bit more technical than I understand! ;) But your test file is really well organized so it will be a good one for them to test - and I appreciate you sharing it. 

It's a tough position, but one we're happy to take on in advocating for all of you here in the forums and through support cases. I'll be back in touch soon! :-) 

Cool.  I wanted it to work pretty bad.  I'm wondering if maybe SL sets new keyframe rates when it auto-compresses videos, even if it's already an mp4.  And I'm wondering if there is a way to stop that compression, if that's the case.  

Anyway, just thinking out loud.  Thanks again Ashley!

Thanks Dan - the file was really helpful for our testing. :)

As far as stopping compression you can do that for certain MP4 files as detailed here. 

SUCCESS!!

I can't believe I didn't know that setting was there.  So yeah, I set it to not compress, and it works like gang-busters.

Adjusting keyframes may not be an option for the average developer, but maybe I'll put a little tutorial together on how to do it in Adobe Premier.

Thanks again for all your help Ashley.  Problem...solved. 

Oh, it's also worth noting that adding additional keyframes to these videos didn't increase video size at all.  

Happy to hear it Dan - and we love tutorials, so show us what you've got! 

Hi Ashley.  Sorry, just got around to this.   Here's a video explaining the problem, and how to fix it by adjusting keyframes with premier pro.  Hope it helps some people!

Awesome, Dan -- I am sure that will help a lot of folks! Thanks for stopping back in to share. :)

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.

Sweeeeeeeeet.
