I was wondering how people are created clones. I've been messing with the program for awhile and can't figure it out. I know theres a tutorial on it but its for chromonator not composite lab. Any help would be very useful. Thanks.

first you have your first clip. then you take the other clip and place it on top of the first clip in the timeline. Then in the second clip, you go into matte and create a freehand garbage matte. Make it roughly around your "clone". Then close up the drawing and click animate. Then click the toggle that says "Revert shape:" make sure it says "revert shape: off". Now animate the garbage matte so that it never gets in the way of the "clone"

Remeber to always have the camera locked in place when your making your clone clips.

Hope this helps, and if you have questions, feel free to ask

Look at the Chromanator tutorial, the same basic steps apply to CompositeLab as well. What you basically do is have 2 layers of video without moving the camera, and then create a mask ont the top layer to remove the part of the frame that you don't want, and therefor your bottom clip will show up below.

It's always best to make sure you film the scene empty of all actors with the camera still locked off as well. This creates a clean background plate which can be useful for filling in problems when overlapping the shots with actors.

Try to avoid locations where you get movement in the background (leaves moving in a breeze for example) as these will highlight the joins between shots.

Another good tip when first doing cloning shots is to make sure that you mentally identify the line where you're going to cut the scene with your mask and try not to have the action cross over that line. While doing so will provide a greater level of interaction, and you may want to do it later, avoiding it initially will make life easier. If you do cross the line, you'll be doing some more complicated cutting and stitching on your masking, and you can't have both clones interacting at the same time in the crossover area.

so in other words.. one clone cannot pass the other unless you are really good at masking?

Or you use green screen.

ok the cloning seems to be going well.. but now i'm encountering another problem.. When my second clone is put int (second part of footage) there is a light square around my clone.. almost as if the scene was shot under a different light.. which it wasn't. contrast doesn't seem to clear it.. any suggestions?

You're getting into other areas of cloning with that question, but actually it can be done. (Obviously, if you look at any of the old twins type tv shows, etc.)

If your clones are not ever crossing the imaginary line you set up, you can do it with a simple square / rectangular blocking mask. That's what I did with my Monty Python clone film. Each clone stays on their own side of the line and a very simple mask will work.

If you want them to "cross the line" then you'll need to modify your mask for all the frames where that happens so they can intrude on the other one's portion of the space.

But to cross, as Petet2 says, you'll probably want something more complex. If you film the set empty for your baseplate, then have a second layer where one of the clones will be filmed "live" on that set, you can then green screen your actor and after keying make that the top layer of the three. (Three assumes you don't have more layers for SFX, etc. I actually had six in the Monty Python thing.) If the greenscreened actor walks all the way across the set, it's not a problem so long as they are intended to pass in front of the clone shot on the live set.

Of course, that sort of thing is going to introduce a nightmare of timing to get it right, particularly if they are talking to each other and interacting in various ways, but yes... I'd say you could definitely do it with some practice and a lot of CLab work, even with an amateur home outfit.

I ran into that same effect with some of the SFX footage I layered in. I didn't notice any difference in ambient light looking at the base footage, but it showed up on the final render. Try taking the top layer and playing with the grading on it... primarily look at lowering the brightness and any aspects affecting the background light levels. I was able to make the "gray box" around the footage disappear entirely that way. Even if it was shot the same, you may need to grade it down to dull it a bit to make it blend in perfectly.

Also make sure to check the layers blending modes.
