Assuming the lighting is solid, you should be in good shape. I haven't used the keying features of iMovie, but I can give you a few tips for After Effects. I'll defer to any power users of AE's keying functionality to chime in with more specific advice. First, you'll probably want to start with the Keylight plugin (from The Foundry). It should come bundled ...

Working at this level, your best bet is probably to use a DSLR and use one of the hacks available to use them as a webcam via USB. Consumer web-cams use a very small sensor which makes it virtually impossible to get any kind of meaningful background blur. You really need the large sensor of a DSLR to best accomplish what you are looking to do.

While not a direct solution, AVISynth supports creating a mask from a Chroma key using ColorKeyMask. You can then use that mask to blend the two layers together by using Mask on the top layer and then Layering them together. You could then just feed files in to the script and use FFMPEG or something similar to write out the frame stream from AVISynth. ...

Actually, your best bet is to use a PCIe or USB 3.0 HDMI input card, like a Blackmagic Intensity, which will take the clean HDMI output of many high quality cameras (e.g: a Nikon D600 or D800, a Canon C100 or C300, etc.) and make it available to other apps on your computer. This is what professional productions do for green screen work to ensure they're ...

Wattage has nothing to do with achieving natural lighting. The amount of diffusion and placement does. More light is ALWAYS better because it results in more signal to the camera and more options as far as ISO, aperture and shutter speed. Nothing you setup with artificial lights (particularly on your budget) will come close to the level of the sun on ...

It depends, you can typically adjust a tolerance for the level of removal. If the colors of green are closer than the next nearest color, you should be fine, if not, then you would have to do two keys, though I would expect you should be able to stack two layers to get the necessary transparency. (Basically keying over a keyed image, since the result of a ...
