I have tried uploading my video as an MP4 but that wasn't working, so I tried the Youtube op]tion that was mentioned here and that isn't working either. What am I doing wrong?
I branched and moved this to a new topic for you. The old discussion to which you posted is 5 years out of date.
Please show us your YouTube embed code.
Did you upload your work and test it online?
#1 have removed your duplicate post to avoid confusion. Please confine replies to this discussion.
#2 YouTube embed code is NOT the same as code for self-hosted videos.
#3 Upload your work to your web server. Post the URL here so we can check it to see what's missing.
