Video levels

Sep 05, 2018

Hello, I am working on a course that has a few video clips that I need help with. My MP4's have a white background to match the Storyline player and I have set the video options tool Compression to None. When I preview or publish the course the video brightness drops down (in video terms I'm losing about 20 IRE) and the colour shifts a bit too. The project file size doesn't seem to make a difference, the video file size doesn't seem to matter, nor does it matter if there is an audio track. The strange thing is that it happens mostly on Internet Explorer, intermittently in Firefox and not at all in Google Chrome. Unfortunately I am required to use Internet Explorer at work.
Has anyone seen this before?

I should also mention that we are no longer publishing with flash, but when I did a test publish as Flash/HTML5 it looks much better in IE11. (using the most recent version of Storyline 360)

Hi Leslie, here are my publishing properties:

LMS: Scorm 1.2

Format: HTML5

Video Quality 9, Image quality 100%

Here's my Articulate Review output of the project.

Take a look at Transmission Contaminated Water and the slide after. 

I found this thread,  https://community.articulate.com/discussions/articulate-storyline/storyline-360-launching-in-google-chrome-firefox-but-not-in-ie

could that be part of my problem?

Thanks so much for sharing that link so that I could take a look.

I am able to replicate the behavior in Windows 7 with IE 11, but it works as expected in Windows 10 with IE11.

I do see a similar issue reported to our team regarding HD videos.

I'm adding this conversation to the report as we track user impact and so that we can update you here when we can.

Hello Marie-Claude,

As promised, I wanted to pop back in and share the solutions that are working for others running into a similar issue.

Possible ideas: 

  • Set your slide size to default - 720x540 (4:3).
  • Reduce the video width and ensure that it is less than the width of your slide size.
    • Adjust the video width size to about 998 or smaller.
  • Turn video compression off.

Hope that helps you as well :)
