ID export format for animated content?

I am creating a document using a 2017 release of InDesign (12.x) and would like to include short clips of animated content.  Our current documents are mechanical assembly instructions containing text and jpegs that are output in PDF(Print) format for use on both PC and iPad devices.  After experimenting with adding animated (MP4) content to the documents I found that although I was able to play the content on a PC using a PDF(Interactive) document, the iPad will not play the PDF's animated flash content.  I have experimented with exporting the document as an ePub for the iPad but this requires saving and maintaining updates to two parallel files (PDF and ePub) per book due to text formatting and layered object constraints with the iPad. Ideally we would like to maintain the PDF format as there are several hundred documents that would need to be converted over to a new format.  Is there a better format, or other options, for exporting the document that can be read on both platforms and still retain the video content?
