Sounds like an IDI to me. It's hard to tell engine noises on videos. By chuffing I guess you hear some air? Chuffing noise could be coming from your vacuum pump. Have you noticed a hard brake pedal? Has the brake warning light been coming on while the parking brake is off? That could signal a weak vacuum pump.

Could also be an exhaust leak?

You might want to try using a stethoscope to track down the tick. You can also use a section of tubing and listen through that. NAPA had a mechanic's stethoscope for $10 and I was able to track the tick to the passenger side on my truck. I think I have a sticky exhaust valve because the tick and chuffing comes and goes. Might be worth looking under the valve covers.
