Hello ,
I am having a slight problem in making my talking head videos. I make them using a green screen. Once the video has been recorded I pull it into Clipchamp. I then get a picture, usually from Pixabay or Unsplash, and pull that into Clipchamp as well. I then use the “effects” button in Clipchamp to use the picture as a background in the video. This all seems to work very well except for one issue. There is a slight grainy movement in the background as I play the video. Can anyone tell me how to fix this problem? I am using a Canon DSLR camera, and the green screen is pulled tight.
