 Hi, my name is Fumiro. I'm a frame artist based in New York. Today, I want to show you a little tip on how to refine a dirty green screen edge, especially a jagged edge. This tip may get a very good result, but please bear in mind. It's not always a case. Sometimes needs more detailed treatment to get the best result. If you could get a very high quality green screen plate, probably you don't have to concern too much about the edge treatment. However, sometimes you have to comb not the best condition plate or high chroma difference costume, especially red costume like this green plate. As you can see, there's a little bit of an artifact on the edge of the subject and the and the hair hurts jaggy too. How can you fix that? Someone may be using edge detect for refining edge, but I'm gonna show you adding just two frame default nodes and softened edge. Let's take a look at this green screen comp node. I'm using additive gear as everybody using these days and here is normal gear. It's keying out just a little bit harsh way. This key is to fit up inside of body part. The additive gear is for the edge and adjust the color of the spilled front and comp them together. Let's take a look at comp results. As you can see in the hair part key out very nicely, but still you can see artifacts on the edge of the face here and the costume edge too. So to make this edge looks better, I use two pixel spread on the green plate at the beginning and one is connected to the normal key. The idea is very simple. The first pixel spread expanding the subject edge and bring that edge back until to the same shape in the second node. That makes softened edge artifact. Okay, let's try that. Add a pixel spread and make sure the split mode is set to expansion and expand just little until getting to the point to clean the artifact. Okay? Bring it up one more pixel spread then this time change the mode contraction and bring the edge expansion back to the point where the plate is. As you can see these two nodes softened only the edge of the artifact sets and here's a comparison. It's softened the artifact nicely and here too. The less abstract is pretty much the same as usual comp. Sometimes these artifacts appear on the edge between high chroma difference plate. This tip may usable on another type of comp to solve or refine your result. If you want to adjust the value simply just adjust these two pixel spread nodes value. I hope you guys enjoyed it. Thanks for watching.
