Edit HTML directly (FlowPlayer)

Forgive me if this is WAY too basic (I am sure it is), but I am just trying to implement the HTML-5 version of FlowPlayer in a test site, and banging my (inexperienced) head.
1: FlowPlayer isn’t integrated into WP or Enfold, so I assume I need to manipulate the HTML of my post directly. Is that possible within the WP environment, or do I need to actually drill into the the files and edit there? I have looked at the Video post format, thinking that had to be at least a place to start, but I suspect that is for locally stored video, where the whole post is the player, not the hybrid post with S3/Cloudfront hosted video I am looking to do. But happy to be wrong of course.
2: Is there a way to make this easier, such as creating a new Post Type template with the Flow Player code already in place?

That said, I would love to just hire a consultant to help with both the WP side of things, and checking for best practice on the Amazon side of things, so any recommendations there are greatly appreciated. I had looked at going the Elance route, but that looks like another Shaft the Provider situation, just like Udemy that I am working towards getting away from, thus the need for video.

Thanks!
