Some Videos stop playing...but not all

I've been having the same issue for months now, and reported it a few times. The only thing that I've been able to notice is that if you click on the video on the slide in the storyline file, then click on Options, if the Compression tab is grayed out, then that video will not play.

The response I get usually is to make sure that I'm working on my hard drive and not on a server. Any time I'm working with large files or videos I always move everything to my hard drive, so I'm pretty sure that has nothing to do with it.

This happens on the Review 360 website, as well as the LMS, but the videos always load fine when previewing in Storyline.

The only thing I've been able to do to resolve these issues (and they don't always work the first time) is to republish the video in Adobe Premiere as a new .mp4. The weird thing is these videos were either made by me or my marketing department in Adobe Premiere as well, but republishing it will can sometimes fix it.

The other option that usually works is to reset to standard optimization for video quality. I've had issues with Adaptive streaming quality as well.

I've had the most success by lowering the quality down to 5.
