Does anyone have experience with the PNG sequence animation?
I have small 3 to 4 seconds animations across my project which are done using a sequence of PNG images arranged 8 frames per second. The preview of the animations is fine in the storyline preview.
But there is this flickering on every animation when played for the first time in the published folder. When we replay the animation everything seems good as it supposed to be. But during the fresh load of every slide, this flickering is happening.
Any ideas on how to deal with this?
I have attached a short video of this flickering and also replay of the same animation.
Although I don't have experience with the PNG sequence animation, I'm curious whether the same problem happens when you test the published output on a web server. If you don't have a web server handy, Tempshare is a good option.
Also, what version number of Storyline are you using? You can check by going to Help >> About Storyline.
My colleague, Alyssa beat me to it! I would also suggest to check what browser(s) you testing it in? The supported browsers will depend on your Storyline version, so if you want to let me know that I can share some recommendations!
Yes, I did test it in LMS(Moodle) and I am using storyline360.
I never noticed the change between browsers, but now you mentioned I just noticed that the flickering is not happening only in chrome. Firefox and other browsers are flickering.
The flicker is happening in firefox even on LMS, I don't think that's a preload or cache issue. Is there anything that I can do to avoid that flicker?
Thanks again for the reply, if not I would have never noticed that browser thing.
Thanks, Tejaswi. Mind sharing a copy of that file with us? You can keep it private by sending it through this link. We'll take a look, test it in a few different browsers, and let you know what we find!
Thanks for reaching out to let us know you've run into a similar issue.
I do not have an update to provide on this, but verified that it is still open with our team.
Seems to be directly related to a timeline sequence/duration when viewing the HTML5 version of the course in Firefox initially. A refresh seems to correct it. Is that what you're experiencing as well.
The only listed workaround is to utilize a different browser or view Flash output when viewing in Firefox.

Hi Alyssa,
I submitted a support case and attached the zip file in there. It was just a slide of the same animation that I have shown in the video.
The Case number is 01290339. Thanks for your support.
Thanks, Teja! Our Support Engineers will reach out as soon as they've tested your file, and I'll follow along with your case, as well.
I was wondering has there been any update on this issue?
