I have always wondered, how do you go about making something look like you have filmed it all night long and sped it up really quick? In the movie paranormal activity did they actually film them sleeping all night, how did they do that?
Help a brother out?:D?
You're referring to a time lapse I take it?
Basically, you film for a long time then speed it up. For a quick practical lesson, take your camera and film yourself doing ANYTHING for a decent amount of time, lets say 5 minutes or so. Then when you put it in your editor, speed up the footage a lot so that the duration of the clip is significantly reduced. Now, you should have a concise shot of yourself moving super fast through time.
I haven't seen Paranormal Activity yet, but I doubt they would have filmed all night: that would be incredibly inefficient. Even in nature docs and such, it's my understanding that when they do those really long time lapses (like sun sets, grass growing, etc) they set a camera to take a shot periodically, at something like 1 minute intervals and THEN speed it up. So it would be my guess that for the movie you're referring to they would have filmed over a substantial amount of time (definitely not hours though), but probably acted out at an accelerated pace and even with controlled lighting to make it look like morning came up (or something, I haven't seen the shot).
Hope that helps!

I'm guessing you want to fake sped-up footage of someone sleeping.
If you just filmed your actors lying there for five minutes, and then sped it up, it woulnd't really look like you had been filming them for hours, because poeple change position in sleep several times during the night.
To get convincing footage like that, you'd have to film your actors for, say, three minutes, and get your actors to change their positions many times during the period. Just like they would if they were tossing and turning frequently. Don't let them do it too much, just enough to make it look like they're asleep but changing positions normally, say, every 45 minutes, or whatever it is. Then speed up that footage in your NLE.
