I was able to take 3 videos further highlighting these symptoms:

1) This is BEFORE the car is started. Hasn't been driven for 5 days so the radiator is dry.

2) This is AFTER a 70 mile road trip. Car maintained its temperature but you can see the leak. Could be the upper hose as ALEC shared as the coolant does appear to be concentrated in that area.

3) Wetness on the venting hose.
