How do you get this effect?

Post by Gallup » Mon Jul 25, 2005 9:32 pm

This question has most likey been asked before, but whot program can you use to get the effect where you take one part of a scene, such as a person, and place them on a completely different background? I have been trying to figure this out for months now and am at a complete loss. I have heard that Adobe can do this, but I use DIVX and XVID files for my editing and as most people know the two do not go together. Please reply if you can help me out.

OK, this is not a simple thing. You have to mask the characters out frame by frame to put them on a new background. You can, hypothetically, do it with any photoediting prog and a video editing prog capable of masking.

What u wanna do by the sounds of it is rotoscope the charater out of one scene then superimpose him onto a new one.

I would suggest the best way to go about it if ure using divx/xvid as ure source, is 1st get a copy of somthing like virtualdub and re-encode ure source clip with somthing like a lossless codec. This will give u the ability to import it into adobe after-effect.

Once you manage to get it into that program, set up you timeline around the clip you want to rotoscope, and using a technique called "vector paint" inside after-effects, you can change the background around the character to any single solid color u like. Be prepared to spend alot of time at it, u hafta go through the clip frame by frame and paint it out.

Then, all u need to do is key out the solid color u painted on as the background, then using a couple simple layers, set the new background you want to use behind the layer you key'd.
