Splitting and keying different parts of a music video – Best method?
I couldent find anyone who explained this exactly, so here goes.
I have a music video shot entirely on green screen, then edited in FCP before exporting a raw .mov file.
I import this into AE, and make it a comp.
Now what is the best method of getting each diffrent clip keyed and garbage matted?
I’ve tried splitting the clip, but when i put the key on just the one short clip, the rest still gets keyed as well. Same goes for garbage mattes..
Anyone have a link to a tutorial explaining this in particular, or could give a good explenation?
EDIT: This might need a seperate question. How to i make a mask where the key does not apply inside the person. F.eks a piece of a T-Shirt. For some reason AE also keyes out the yellow in a T-shirt and makes it orange…

Ok, when you say that when you apply the key to just one clip, the rest of them get keyed as well, you’re losing me.
If you apply an effect to one clip, it only applies to that one. You must be doing something slightly wrong… to clarify, if you have the whole video in one layer, then split that layer (so that you now have 2 layers, with part on each), both those layers will be separate (so they won’t both react to a keyer or mask. If you are getting results other than that, maybe post us a screenshot so we can see what you’re doing.

Let me try to explain since i now came a little bit further in the process.
When i took the original clip, and just split it with cmd+shift+D i would choose the clip that came into a new layer and apply keylight. When i browsed the rest of the timeline, this would also be keyed.. It might not sound possible, but this is for some reason what i would end up with. Same goes for trying to make a garbage matte.
Next step i was introduced to was splitting the clips, and then making then into a pre-comp (cmd+shift+C). I was told to choose “leave attributes”. This would leave the clip in the layer and in the right position, but when trying to open the new composition i would still have the entire length of the footage inside the pre-comp.
The method i am using now, is the same but choosing move attributes instead. When doing this, the small split part that i made extends back to the entire footage (inside the original comp). So i drag the ends bak to match the gap between the different splits, and so i have my little snippet. When i make my garbage matt and key it now restricts to the one clip, so i guess i kinda found what i was looking for.
However i have a suspicion that this is possible in an easier way?
Sorry is the explenation here is not entirely easy to get, im from Norway 😉

Ok, you have me baffled. The first way, splitting the clip then applying the effect, should NOT apply it to both clips. If you select the other clip, does Keylight show up in the effects panel (i.e is it ACTUALLY being applied to both)?
Tell me, you aren’t looking in the LAYER window when you say it’s being applied to the whole clip? You always need to check your results in the comp window.
