Green screen video made easy

When you’re trying to work out how to do green screen video the first place to start would be with your actual green screen. This can be a material which you hang or stretch behind where your talent is going to stand. It is really easy to find from various sources including eBay, either small cuts of green screen material, or quite large sheets of the stuff. On the other hand, what you could do is to buy some paint of the right colour which is a putrid bright green. If you have a nice flat wall that you can paint with this vomit coloured, vomit inducing colour of paint, it could be a perfect solution for your chromakey background. Obviously one of the cons for this would be that you don’t have any mobility, but it’s something that you could consider for a more permanent video studio.

Green screen Final Cut Pro

In the video on this VideoMagical post, we are looking at green screen iMovieediting. In Final Cut Pro X, you will find that the chroma key green screen editing is just as easy as it is with iMovie. One of my green screen tips in Final Cut Pro is that you can do samples of the green screen at various points during the movie. So that if I have found an area that for some reason at one point during the move does not work, then I can make another selection of the green, to improve the green screen editing. Still bear in mind though, that if you have got good lighting for green screen you will have less tweaking of the settings to do.

The actor will also be required perhaps to react to objects that are not really there.

Green screen background videos

Once you have managed to key out the green screen background then you can add green screen background videos. You want to try and make it so that your talent will to fit into the background scene that you add. If the background video is of a sunny summers day, then your talent will need to be dressed accordingly as well as being lit suitably. You may also want to take into account the shadows and the direction of light, so that the foreground and the added background will match.
