I have the HF20 and I shot two scenes with it last weekend at 24/HD. I copied the MTS files it made and they imported straight into Adobe Premiere CS4 with no problem. The colors are rich and it was ridiculously easy to learn all of the settings. Face detection works without any intervention. I don't have any 1080p video online for free at the moment, but I did create some movie galleries downgrading to "vhs" quality here. Keep in mind this was shot with minimal light. The next scenes I post were shot fully illuminated against a green screen. Total thumbs up!
