To the stabilizer.

If you're filming yourself, this is the easiest way to capture the shot on film.

Here is the predicament-

filming yourself with a tree arm will give you the best B-roll, pre shot footage and post shot footage. The problem with tree arm mounted cameras on a self filmed hunt is this; when that animal comes in, you will have a heck of a time deciding "do I get ready for shooting, or filming" ? You'll be trying to line the animal up in the frame, then you'll draw your bow- by that time, the animal will be out of the frame. Trust me, it's a pain in the butt.

using a bow mounted camera limits the quality of camera you can use and also the footage you will be able to get, because your bow and camera are now one(trust me, not easier...just easier to capture the kill shot because your line of aim is the cameras line of focus).
