PPT Animations Exported as Video

Similar to this initial thread, I have mp4 files exported from PPTX where I'd like to insert them in Rise360.  In the PPTX I inserted a 'New Photo Album' (under Images tab) which allows a series of images to be placed in the PPTX file on individual slides.  Then I exported this PPTX to "Create a video" which provides the mp4 file and I choose 0.1 seconds between slides.  The images are of satellite imagery so making the mp4 provides an animation in time of the satellite data.  When inserted via video block in Rise360 the animation will play the first 5 frames, but then it seems to skip frames only showing every 6th frame until the end of the animation.  I've exported as medium and HD quality and same result occurs.  I can play the mp4 outside of Rise via Windows Media Player just fine, but now I just tried to play it in Chrome and the images look messed up even though it does play every frame.  I'm concluding that mp4 exported from pptx is not always going to work in Rise360's block, but I'm looking for help or confirmation.
