Surely a lot depends on pilot experience and qualifications and aircraft de-icing and navaid capability/availability.
For a day VFR pilot, preparing to fly at 14:30 with sunset at 16:00 (L) doesn't leave a great deal of time for fuelling/flying.
I've sprayed de-icing fluid onto a Warrior and moved it into the sun early to mid morning but that is at a time of day when with the sun out you can expect the temperature to hold steady or rise, and for the sun to keep off any ice formation.
Without de-icing on the aircraft, then with ice forming, and the sun going down then I'd be straight back into the hangar and off to a pub with a roaring fire. [Where did that last bit come from, some sort of folk memory?]
On top of that, what were the temperature and dew point? I'd guess pretty close if the air was saturated enough for ice to form. (Is that true?). I'd guess they were pretty close, so with the afternoon temperature dropping as the sun descends you could quickly have fog forming and loss of runway availability - even if the airfield itself didn't close the runway.
At the other extreme, if the pilot is night and fully IFR qualified and current, the aircraft has FIKI capability, and all the Nav/landing aids are fully functional and you have fuel to get to an operational major airfield (with ILS) plus a diversion then off you go if you need to (currency?) or want to because you would enjoy the flight and the possible landing fees at the diversion airfields. Or alternatively adjourn to the pub.
Edit- Gone back to the video, no sign of de-icing boots on the a/c. Pub.
