Hi, I need to remove the green screen gradient. When I am using the colorkey option blend and similarity. I found there is spills coming in hair. Please can you suggest me the method to removing that spill from the command line in FFMPEG.
My command is as follow : ffmpeg -i background_video.mp4 -i overlaying_video_with_green_screen.mp4 -filter_complex "[0:v]setpts=PTS-STARTPTS [V1]; [1:v] eq=1.0:0:1.3:2.4:0.175686275:0.103529412:0.031372549:0.4, curves=r='0.2/0.5':g='0.4/0.5':b='0.2/0.5', *colorkey=#0a7c58:0.1:0.2*, pad=width=1280:height=1020:x=0:y=0:color=#000000, drawtext=fontsize=50:fontcolor=#ffffff: box=1: boxcolor=#000000:fontfile=/data/arial.ttf:text='Enter your video message here':x=20:y=820, setpts=PTS-STARTPTS, scale=1280:-1[V2]; [V1][V2]overlay=shortest=1:x=1:y=1" -pix_fmt yuv420p -y final_video.mp4 I will wait for your response.
