Is there any free software available for green-screening? I prefer Linux, but Windows is also fine.

    The title of this question doesn't really match the question asked in its body. I recommend that OP change one or the other to clarify. A circular inset could easily be achieved without chroma keying, for example. Oct 5, 2014 at 14:21
  • Any relatively basic non-linear editor should support greenscreen and what is available changes often enough to put this in the realm of a product recommendation question that is better answered by an up to date Google search for products.

Depends on what your definition of good green screen is.

In terms of free software to do green screen well...Only one that I can even think of that does keying is Da Vinci Lite which is free from blackmagic's website. It is pretty complex and pro based, but with a little searching around you might find what you want. I am not sure if you can technically do green screen with it though.

  • Yes, Resolve can do this, though I'm not sure if it is suppoted in lite or not. Here is a tutorial I found on it with some quick searching.

  • Resolve can greenscreen, but it's not made for it. It doesn't, for instance, have built-in spill suppression or light wrap. Because it's node based, you can hack your way around these limitations, but it's still quicker to greenscreen with purpose-built apps and plugins. Also, resolve currently won't export an alpha channel, even in codecs which support alphas. Oct 1, 2014 at 13:06
  • you can use OBS which can key. it is livesreaming software so the keyer is meant for face cams, but it should work.

  • @JasonConrad I understand its not designed for it, but the OP asked for free applications that are good at it, and I don't think that truly exists Oct 2, 2014 at 18:32

    don't get me wrong. I'm a huge proponent of Resolve. I'm just saying, don't expect to get an alpha channel out of it. Oct 5, 2014 at 14:02

If you don't mind learning there is a tool that has them all, green screen, video editing, 3D, compositing...

The name's Blender
