Vic is free to keep that single comma outside of the quotes. (This *should* also apply to Windows "DOS box" shell.)

They do, but your first overlay takes two inputs to create one output, and you chain that one output to the subsequent overlay as input. But that again needs two inputs. A complex filter, as Ryan proposed, does do this correctly: > give this a try -filter_complex "[0][1]overlay=enable='between(t,1,5)'[tmp]; > [tmp][1]overlay=enable='between(t,10,20)'" Moritz _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
