You can easily embed YouTube or Vimeo videos into your FAQs and/or Workflows. Within the FAQ compose interface press the video icon. This will bring up an area where you can paste the URL of the video you wish to embed.
If you want to use some of the embed customisation options that YouTube and Vimeo offer you should use the full embed code from those platforms (rather than just pasting the URL). Paste their embed code into the lower part of the MyMalcolm insert video dialog.
For Workflows add a content element to your Workflow, then in the Workflow builder click to edit the content element and hit the video icon. This will bring up the same dialog as above.
