[UPDATE] I’ve added 6 more color key filters (red, green, blue, cyan, magenta, yellow).
Download the free OBS Studio cinematic LUT pack with the link below. Just unlock the download button and download the .zip file. Once you unpacked the .zip file apply the .png file via the ‘apply LUT’ filter to your video device (webcam) within OBS. You might want to watch the step-by-step tutorial video if you don’t know how to do it. If you have any questions or suggestions feel free to leave a comment.
