You can embed Youtube, Facebook, Vimeo and Twitter videos on your Revv pages. For security reasons, you cannot embed any other rich media on your page like iframes or scripts.
Embedding a video
Go to the page you would like to edit in your page builder.
Click on Creative from the left-hand sidebar. Find the Video Embed Code field.
Enter the embed code for your video. Here's an example of a Facebook embed code syntax:
<iframe src="https://www.facebook.com/plugins/video.php?href=https%3A%2F%2Fwww.facebook.com%2FSpaceX%2Fvideos%2F10157486010400131%2F&show_text=0" width="100%" style="border:none;overflow:hidden" scrolling="no" frameborder="0" allowTransparency="true" allowFullScreen="true"></iframe>
5. Click Save.
Note that you will probably want to edit the width to be 100% wide so your video always fits on your form.
