Does it seem to be worse in the area your filming? whilst I agree it sounds tappet it may be the bearings on the A/C pulleys. Try disconnecting the A/C belt to see if it goes away

Yes and if its not that, you could take the fan belt off as well, could be water pump..or alternator packing up (obviously don't run it for more than a minute like that)
