Make a gradient that is the same size as your input video: $ convert -size 640x480 gradient: gradient.png Then use ffmpeg (untested example): $ ffmpeg -i video.mkv -loop 1 -i gradient.png -filter_complex \ "[0:v]boxblur[blur]; \ [blur][1:v]alphamerge[merged]; \ [0:v][merged]overlay[out]" \ -map "[out]" output.mkv _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
