I made a promo video for AH2 back when I flew regularly. I believe that fast-paced kill videos and competitive reels attract more players and gets rivalries going. I'd make more if I still played. Hell, if I had AH3 footage, I'd probably make new ones just for fun.
Here was my first attempt. I think I did pretty good.
Without trying to stir drama, I feel Skyyr's vids would be good advertisements for fast-paced combat footage, but I doubt Hitech and he are on talking terms

His AH3 stuff was pretty awesome. Players should post more stuff like this. This would attract me if I hadn't heard of AH before.
I saw Hitech is releasing updates again. If he intends to do AH4, we definitely need more community films being posted.
