I have videoed several kills of hogs at feeders. I made a bracket that screws into the tree and use the head from my tripod to hold my Sony handycam. I probably dont have more than about $3 bucks in the whole bracket, and I already had the tripod head. I just set it on the target area, and leave it running once the hogs come into the feed. Most of them were taken after sundown by spotlight so I dont worry about following them after the shot. It is great to be able to relive the experience with others later.
I have one bit of footage of my getting 2 coons with one arrow too.
