Yes – it’s extremely easy to do green screen badly like that.

Think about it a bit. The killer flaw in that video was that the lava didn’t move when the camera did, so it’s obviously a trick to the viewer.

Step back and think about what green screen can do. Replace one colour with another bit of a picture. If the green sword goes left to right then the image of the lava needs to go left to right at exactly the same speed. On the other hand making the sword a solid yellow colour using the green as a key would work, but if you creat a metalic pattern, checker board style say, then as that sword moves you have to track, rotate and scale each single frame, and even with the tools in your editor or other software it will take you a long time to get right. I wouldn’t want to do it! If you can find an effect that doesn’t matter if it doesn’t track, then it can work much more quickly. Normally you completely replace the green item, but you can use the effect to add more gentle FX, but who carries a green sword?
