Do you key out the green, and merge with the background shot, and then colourise the scene as a whole? Or do I colourise then key? We have some green footage which is going to be keyed but was wondering, in which order do you work. I'm editing a film at the moment, and am going to be colourising the final video using Apple Color. You also probably want to avoid any compression, in either HD or SD.
Have a look at the options when you're rendering out of AE. Some codecs add it as a fourth chanel, like RGB-A and some *premultiply* the alpha into the RGB signal. You just need to use a compressor that support's alpha channels or millions+ (the + means alpha). You then want to preserve your alpha channel so you can take the clips back into FCP for your final conform (which is a perfectly acceptable way of doing this). Once you've locked of you edit, you can lay the clips off to AE. You can easily doa temp one in FCP just to check that it's going to work for the edit. This only works if you plan to do it, and it sounds like it might be too late for you now.Īnd so, you should do the key and composite first. You might be trying to match the lighting in your foreground comp or tone to your final composite, so you can do what you need to there, and the correction is preserved, because you don't have to worry about the key that you generate. The second pass you do, you correct for the foreground elements. You then use this layer to generate the matte. The first pass you correct for the background surface that you're keying.
Noone seems to do it anymore, but it used to work quite well to do two passes in telecine. This will keep the alpha channel intact so you can comp it over other stuff in FCP. To answer your question about the background being "black," you can export the keyed layer from AE as a QuickTime using the PNG compressor. I would only make minor adjustments here to preserve your color tweaking options in Color. However, you will probably need to do some color tweaking to the image to get it to match the background plate. It's the very last step prior to final output / downconvert / MPEG2 compression for DVD, etc. Normally, color correction is never done until the show is completely finished with all visual effects added. The color correction would be done in Color.
#KEYLIGHT PLUGIN FCPX SOFTWARE#
Yes, I know that technically FCP can do basic compositing, but you'll have more control over the final comp in software that is better suited for the task.
#KEYLIGHT PLUGIN FCPX PRO#
Final Cut Pro is an editor as far as I'm concerned, not compositing software. You would both pull the key and do the final composite within After Effects.
