Have you tried to fill the cooling system and let the car idle for several minutes and then start inspecting for possible leaks?
From the vid your coolant/water looks brownish...which is a good sign of cooling system contamination probably rust buildup in the radiator to which a good quality cooling system flush will help condition the cooling system back up. This is why I asked if you have the original radiator or a new one...if its the original I would replace it with a new one and replace the thermostat at that too.
Just recently i was loosing coolant and couldn't figure out where...it was leaking from the tranny side. I finally found the leak was coming from one of the water feed lines to the turbo which has a small slit on the hose and the coolant was running down that line to the lower rad hose down to the center crossmember and eventually leaking around the tranny area which was throwing me off finding the leak.
I would still do a compression test anyways...just to rule out a bad headgasket and to see if the overheating hasn't affected the headgasket.
