uploading a Libre Impress (Powerpoint) file

I am trying to upload a PowerPoint slideshow to my site. It has background music and is timed to advance automatically.

I have tried uploading to various cloud platforms like Slide Share and Vimeo but there is always a problem. Either the font will not show or the presentation is too large or the file type is wrong or the link goes to wordpad.

I have tried various plug-ins like GroupDoc, GoogleDoc and HTMLS Slideshow. None of them seem to like my slideshow.

The version of PowerPoint I have is very old so I converted the presentation to Libre Office. Should I convert it into a video? How do I do that with Libre Office? If this is incorrect what do I save it as?

I am probably not being very clear. I will clarify as best I can if I have confused you.
