I'am a new one here. first of all sorry for my bad english :)
So, I'am not sure it's a right place to ask about that (I mean Speacial Effect section) but...
Is anyone know how to make a video effect (or this is filming technique) which is looks like slow motion in real time. For example "Nightwish" music video "Wish I Had An Angel" (http://www.youtube.com/watch?v=AcyTR5mEC_E)
Of course, I found one tip how to make that, it's when you speed up music to 150%, then shoot the artists with this fast music and then in editing software slow down this video. Hmm, probably it's works, but maybe here is some other options how to make that?
