I tend to just leave my foot on the gas for a split second after pressing in the clutch, that lets the rpms bump a little until I get it in gear and feet back in position. I think I developed that habbit because I always tried to put my heel on the brake and toes on the gas, versus toe on brake and heel on gas like in the video. I'll have to try that, but conceptually it seems like it'd be much easier than how I always tried it.
