Blurred zoom region

Apr 09, 2018


I made a "zoom region" on my slide for the learner see a close-up view of a portion of a document. But when it zoom, my document get's blurred !


The document is in high quality and the problem doesn't exist with the "picture zoom" (but it's not what i want).


Do you have any ideas for helping me ? Thanks !

Hi there, Diana.  Our team is looking at an issue where zoom regions blur high-definition images in the HTML5 output of Storyline 360.  It sounds like it might match what you're seeing.

Are you able to include Flash output in your publishing options?  If viewed in a browser that has Flash Player enabled, you should see some improvement in the zoom quality.

I'll keep you updated on any new information we can share.  Thanks for reaching out!

Hi Diana, 

The blurred effect may be due two factors: 

1) Your zoom is defined around a very small area.

2) Your player dimension is also small, resulting in all images inside the player be rendered proportionaly smaller.

Even high quality source images can be affected by these two factors.

The zoom on click works in a different way so this is why they present different results.

Hey Jon,

Thanks for chiming in. We are seeing some issues in Storyline 360 with images appearing blurry when you apply a zoom region to a slide. 

In your other post, you mentioned you're having other issues like lag and object shift. We'll want to have a look at your file to see exactly what's going on there.

Alyssa I didn't see your response until N B added to the thread today. I'm glad you are seeing the issue as well and look forward to the update that fixes the issue(s).

Unfortunately I cannot share project files for confidentiality reasons, but it seems like a universal problem. Everyone at my company using SL360 (about 8 of us) is having this same issue.

As for lag and object shift, that is persistent but seems to vary by degree from project to project.

Hi, N B: I'm so sorry you've also come across this problem. You're in the right place to be in the know with any new information, and here's an inside look at how we tackle bugs when they're reported!

Hi, Jon: Thanks for sharing this extra piece with us! Oh my ..we'll definitely need to dig in and see if we can nail down why everyone at the company is experiencing those issues. We can appreciate confidentiality and are happy to sign an NDA, if that works for you and your team. Just let us know!

To all: We'd love to take a look at a .story file to make sure we see what you see during Preview and after Publish! As my teammate, Alyssa, mentioned above: The more sample files we have of this behavior, the better!  

If you're able to share a project with us, feel free to share it privately via this link or add the project to this conversation by using the Add Attachment button in your reply. We're standing by!

Ah, sorry for the confusion there, Jon!

We're continuing to look at the reported cases of the issue: In the HTML5 output (Storyline 360), images appear blurry when a zoom region is applied to a slide; I understood the new insight as everyone at the company is experiencing lag and object shift in addition to the blur and got worried.

My apologies again. Let me know if you have any other questions, I'm happy to help!

Hello, I'm hoping this is still the correct thread to post this on. Are there any updates on this issue, now that HTML5 is even more prevalent? I'm working on an image-heavy where image quality is important, and would love to be able know if I need to apply a workaround instead of using the built-in Zoom feature.

Katie Riggio

Hi Julia,

Thank you for checking in, and I'm sorry you ran into this problem.

I wish we had an update, as this is no small fix. The moment there's more information to share, we'll notify this discussion!

In the meantime, we're happy to troubleshoot the file to offer tailored support. Please use this secure upload link if you can share the file.

Hi Michael,

I'm sorry to hear you're running into this as well! We don't have any updates to share on a fix for this yet, as it is still in the early stages of review based on our How We Tackle Bugs article.

To help you plan, it's unlikely to be fixed in the next couple of updates, but we'll be sure to jump back in here with any news to share.

Hi all!

I am jumping into this discussion to share that we just released Storyline 360 (Build 3.63.27628.0) which includes the fix for the bug where images were blurry if they were in a Zoom Region. Now all you need to do is update Storyline 360 in your Articulate 360 desktop app! If you have additional questions, don't hesitate to reach out in this discussion or in a support case.
