Help With iFrame Video Embed Code - Can Anyone Help Please?

Hi

Can someone help me modify a video iFrame please?

I am setting up some courses on my blog using Thrive Apprentice which is part of Thrive Themes.

All my videos are hosted on Amazon S3 and are easy to add to my 'blog'. However, Thrive Apprentice works differently, and the only way I can add the videos to this section, is by using the 'custom mode' and embedding the code.

I have tried several of the free online iFrame generators, and while they do work, they don't have all the features that I need and I can't seem to work out how to get it right

You can see what the video looks like at the link below. There's NO advertising or buy buttons of any kind on the page... just the video, so I am not trying to pull any kind of gimmick here

Here's the code so far, for that video

<iframe src="https://vseries.s3.amazonaws.com/ClickFunnels/1%20-%20Overview%20for%20Clickfunnels.mp4" height="100%" width="100%" style=" border:0px;float:top;" class=" " id=" " name="test"></iframe>

What I would like adding/removing is:

1. REMOVE "Download Video" and "Picture in Picture" from controls. For some reason these are only showing in Chrome and NOT in Firefox

2. Add the following: Autoplay - Fullscreen - Image URL

Thanks

Bill
