Storyline is not recognzing the MP4 format

I have just experienced the exact same issue with Storyline2.  We have a video tech on staff that rendered off a total of ten videos all with the same settings but the first one will display the same error message as above.  The other nine clips go into Storyline 2 and play just fine but the first is popping up errors. 

I have downloaded it onto my local hard drive multiple times, saved and restarted Storyline and it still seems to pop up the same message.  Is there a size limit for videos?  It is the biggest off all the files I'm working with.

How can a MP4 rendered off with the same settings work for nine videos but then fail on one?

This is not a situation where the settings are incorrect due to the ten videos being batched.  I also can't post any of the work here as the total project size will be close to 10GB and the video in question is about 3GB.
