I (hope I) know that's not what you meant. But it still is another hurdle. The skills to do a decent video are mostly irrelevant to the job you want the guy to do (assuming you want a freelance coder. I obviously understand that you're not going to choose a co-founder based on some textfields and a short bio).

Creating a video is the worst way to get an impression though, in my world. If you meet me on the street we can have a great talk and I am quite confident that my english is more than good (though with an accent that I hate) enough to discuss every practical matter. Doing a video call would be more awkward, but perfectly doable. Sitting alone in front of a camera, selling myself to the world with a broad smile? Nope, sir...

I don't think that I'm alone with that attitude and I doubt that this influences my communication skills in a project let alone my coding abilities.
