Here's what I used for my setup. Fabric/Material The main thing is to find a material that is very green. Walmart sells (at least in Maine) a very green cotton fabric that works well ($9 for 3 yards). I've tried materials that are a lighter green, but without success. One thing you have to watch out for is large wrinkles, which will quickly ruin the ...

Me and my friend made one for a video project. What we did is took a white bed sheet and just painted it with basic green paint. It becomes a stiff starched fabric texture, which works well for hanging it on a wall. To light it, We used just work lights (3 100watt bulbs + unknown wattage) to light it. The lights we used were like this: We just had to play ...

While chroma-keying is a good technique for dealing with solids, it doesn't work so well when dealing with transparent or semi-transparent objects. Because the difference can be very subtle, you want to copy the difference instead or blend off luminance. In Premiere, you can use the Set Matte effect to set a track as a luminance matte. In the case of the ...

First off, you would normally use After Effects for special effects such as Chroma Keying. That being said, Premiere Pro is capable of chroma keying quite decently. Here's an example using free smoke effects by JohnnyFXEffects. Set up your scene as you usually would, and then go to the 'Effects' tab. (1) From the 'Keying' folder, select the 'Chroma Key' ...

Let's first review the basics of green screen: 1) screen about 5 or more feet behind subject so it is out of focus from subject. 2) flat screen, no wrinkles. 3) flat lighting, no shadows, no hot spots. 4) subject can not wear green or wear shiny things or see through things.

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 ...

The simplest way would be to set the blending mode of the smoke clip to "screen". You'll find this setting in the "Effect Controls" panel under Opacity. Screen basically ignores black. A better description is found on Adobe's site: http://helpx.adobe.com/en/photoshop/using/blending-modes.html

I've heard green table clothes from a dollar store work very well. You can stack them to make them more opaque if you like, and the lighting is more important than the material anyway.

I haven't tried chroma keying in Final Cut Express, but I'm pretty sure it depends on your needs and workflow. If you use Premiere for editing movies than AE should be more integrated. Yet, if you really want to get awesome results and have some spare bucks, I'd say you look at some plugins. After all neither AE nor FCE is specialized in chroma keying. ...

You could use a revolving cake stand.

Most likely, they are simply using an output of the notes with transparency. If you output the digital version of the notes with a transparent background you could just layer it over the video once properly aligned and it would work fine. Alternately, a quicker process if they do not support alpha is to just apply a blend between the layers. Since the ...

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. ...

What with the felt-tip pen and the transparency of the writing surface, this actually looks more like they're writing on a transparent whiteboard. Probably perspex, or plexiglass. This type:

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 ...

Everything that Filzilla said is great and on point. BUT the standard chromakey plugin that comes with Vegas is lacking. There really is no way to get around it. I have been doing greenscreen videos for yourmusicmuse.com for 3 years and I have found the NewBlue ChromaKey Pro plugin is perfect. It has the following features: Garbage mask to mask out bad ...

While AE has a chromakey plugin in the box, I have good experience with: http://www.redgiantsoftware.com/news/featured/KeyingSuite11/ There are several tutorials on there website, and this gave me the best results. Of course, your footage is the key

After Effects is well know as a finishing software. The best chroma key plug-in I saw in A.E. was keylight. Very nice full controls, to handle even color/light correction of borders key. I don't know if keylight is avaliable for FCE. Maybe the only benefit inside FCE is rendering time. Real tests can talk a lot more. My vote goes for After Effects.
