No, IMHO there is not enough information in the video for any conclusion about: lean, rich or ideal.

Here are my observations:

Pull start engine
Clamped in a vise! This is a big no no.
I see an electronic ignition is being used on what looks like a mag engine.
Running at a high RPM ( sounds to me like ~ 3500)
There is some light smoke in the exhaust ( no mention of fuel, needle settings, oil ratio, oil type, this list could go on and on...............)

So my conclusion is that with the information in this 10 second video with no written info (like a text inserted page with info):

I can not determine (from the video) whether it is running " rich, lean or ideal".
