hi

ok, so i'm trying to achieve this effect. http://youtu.be/J294A-R1Cjk

not the slo-mo in the disco, the jerky sped up effect when she's shot head on dancing. Is that just a reverse effect of the
"playback song twice as fast, have actor lipsync to that, slow down in post" -effect?

which would be to play the song 2x slower and then, when sped up in post, motion will become jerky and weird looking? this sounds about right in my head but I have a nagging feeling that something else is going on here. maybe it's not 2x slower but 1.5x or something.

I will only have access to the cameras for the days of shooting (doing a music video) so I can't really do that much of playing around. I'll be shooting with a 7d. Has anyone done this and could show me something like, "yeah here's my settings and here's the result"

another example might be the nurses in silent hill http://youtu.be/xLPpIDqwgA0

is there a name for this effect, i've googled my a** off but all I get is hip-hop videos where everything is lipsynced in slomo. :/ (or coldplay's yellow)

thanks guys. /Sam
 
sweet, thanks.. I'll have to try to get my hands on the camera earlier so I can do some tests. Anyone got any more info on achieving this effect would be greatly appreciated.
