Inspire 1 in the wind, two flavors of video

Upgraded the Inspire 1 firmware, everything went OK.  Took the unit out, and was impressed with its stability in the breeze.

I'm terrible at guessing wind speeds, but I'm pretty sure it was 15 mph gusting to 20 mph.  Can anyone guess the windspeed by the flags blowing?

I recorded the video at 4k, 60 mbits/sec, and transcoded a copy to 1080p, 30 mbits/sec.  I've included both... does it make a difference once it's uploaded to Youtube?
