Dear Mr. MarkHunte.
Thank you very much for your suggestion.
I tried your way but after all I failed. Off course I can see the video in PC but I also want to see it in iPad or other smart phone. This is a part I have tried and failed over and over again. Now I manage to work this problem out
with the reference to comments in this forum.
So I have two questions.
①I found that there is "export area in video" in "file", second option in upper part of Hype pro, different from "export as HTML" in same "file" area. Should I export the data including the video from here or export it from "export as HTML"?
②I don't want to adopt ①way as much as possible because the data become heavy.
As in Mr.Daniel's suggestion, I think that it is the best way to use Yutube video URL by uploading in Yutube.
But in this case, the problem was that the video didn't flow automatically. The title character and push button necessarily showed up and it was not cool in appearance. How should I work this out to make it flow automatically?
I am happy if you suggest me other solution.
