Video not playing, shows green screen

As a first troubleshooting step, I would temporarily move one of the "green videos' into one for the first 10 (working) slides and see if the video plays then. That would at least confirm that there is no problem with the encoding of the green videos.

Thank you for the suggestion, I tried that and the videos work just fine as the first slides.

Well, then I would submit a support case, so that the amazing Articulate folks can investigate what may cause this problem in your file. 

Michael, thanks for helping out Becky.

Becky, if you can just update this thread with your case number, I would be happy to follow along.

Leslie,

My case number is #00349045.

Based on feedback I received from the customer support engineer, I determined that it might be an issue with my Flash Player. So I did some googling about Flash Player and MP4 videos not playing and came across the page I linked to below. I followed the steps to disable hardware acceleration, and that seems to have fixed the issue.

Awesome. Thanks for the feedback Becky and thanks for updating Cleo in your case as well.  Just let me know if you need anything further.

I know this reply is incredibly late, but assuming you don't want every user to have to disable their flash "hardware acceleration" just to view your video... I found that moving the video to start with a 1 second delay, it'll make the green screen go away much sooner (within a second or so). I gather It's some sort of buffering issue that happens when the video is a little long. (mine are about 10 mins each).

I ended up starting each video with an image on the top layer, but fading out after a couple seconds, that way it gives the video a second to buffer and the user won't see a green screen. Hope that helps!

Thanks for sharing Ryan! It doesn't matter if it's late, it could help someone else out, so thanks for sharing your solution.

I know this thread is a bit old, but I am working on a project in Storyline that incorporates branching video scenarios. Ran into the green screen issue stated here. I have a lot of slides in succession that have video. What I did was to insert a blank slide in between slides with video. I set a trigger to go to the next slide when the timeline starts so the learner won't see the blank slide. This appears (so far in my testing) to have solved this issue. The only caveat is that if the learner clicks on the next button on the player in quick succession, you will get the green screen after 3 or 4 clicks. I was already planning on creating custom previous and next buttons in the course and not use the player navigation. I will just set the navigation buttons to show at the end of the timeline.

Hi Rob,

Thanks for sharing that here and I'm glad you were able to find a solution that worked for you.
