It really all depends on what system your editing with. If you are using a mac, pc... a laptop, desktop or maybe your phone?

There are a ton of great phone apps I use on the fly if I'm not by my desktop. For a video like this.. I would assume you used a phone to record however you said this was on a gopro. For a video like this... just be sure to remember to adjust volume settings before rendering and posting the final product. Once you are ready to step it up.. whether its a mac or pc is going to be your main concern when considering what programs to use in editing.

When I say cowbell

I just mean the small details that nobody would consider when creating a masterpiece. Something on the lines of.. hooking the gopro on your pups and let them give you the view of what they see. Just a little something I feel might be interesting to explore.
