Keep forward airspeed until the descent is nearly stopped: reduce the rate of descent first, then let the speed come off.
What happened: For 63% of the approach the helicopter was slow and descending fast together, and it met the ground at 444 fpm. A slow, fast descent is hard to stop with collective, and a firm touchdown usually follows.
Watch for: Airspeed and vertical speed together: never low airspeed with a fast descent.
As you slow through about 20 knots near the end, add collective to offset the loss of translational lift, together with the matching pedal. Keep some forward speed until you're close to the ground.

The flight is kept as it was recorded: it ends when the engine is shut down, so a
landing with the rotors turning is a stop along the way, not a new flight.
