1 person in real-time and 1 in slo-mo in the same shot?

[nicolas_arson]

i read a post by someone, pheacon or something (sorry if i got it wrong) and it said that he/she was able to put a 2 moving figures in a shot, one in real time, one in slo-mo. this has been one of my favourite effects in film for a long time. please could you tell me how you do it?
thanx.

Green screen and comp the footage. Speed up one slow down the other.

No, you shouldn't. Really.

i think you could do it split screen to if you kept the camera still, they did it in the pilot to smallville when john kent fell in slow motion and clark ran in at normal speed to show how fast he is, you could do it adobe after effects by cutting round thr object frame by frame

If its a static shot, it doesn't need blue screens etc etc. Shoot it first with the first person, then again with the second person.

Then, err, do something with it in premiere. We did something similar in our latest short, although the speed wasn't changed, but we shot two people walking away, then shot from the same angle a car pulling up, then realised it looked **** like that and so we merged the two, and it worked fine. I'll ask the editor guy or have a play with my Premiere to see how he did it.

Hey, I'm the one that posted that. A friend of mine does all the editing on our movies, so all I know is pretty much what I've seen. You film the person(s) that will be moving in realtime, doing whatever they're doing. Then, seperatly (in a higher frame rate, if you can) film the people that will be moving in slow motion. DO NOT MOVE THE CAMERA!!! The shots must be exactly the same. Unless you have a state of the art track dolly that can move your camera at exactly the same speed flawlessly you'll need this to be a stationary shot. We use Premier, so we capture it then we lay the two shots over eachother and make one half of the screen of one or the other frame transparent and slow down the clip that is supposed to be in slow motion. You also have to make sure the two people on the screen don't cross into the other persons frame (they'll disapear into it). Experiment with this and you can do some impressive special effects. I explained it pretty poorly, so if someone can go into more detail, please do.

Don't forget if you're merging two shots with the same background, do a shot of the background on its own, in case you have to fill in any gaps later

It is quite easy in that there are dozens of ways to do it.
There's general thoery and then how it applies to what you want to achieve.
And I need to know what software specifically because you could be getting into import and export functions.
It will take an hour to type an explination.
