I am now using: offset=$((${cutStart} - ${videoStart} - ${duration})) xfade=xfade=transition=slideleft:duration=${duration}:offset=${offset} time ffmpeg -y \ -ss ${videoStart} -to ${cutStart} -i ${inputFile} \ -ss ${cutEnd} -to ${videoEnd} -i ${inputFile} \ -vcodec libx264 \ -crf 26 \ -acodec libmp3lame -qscale:a 9 \ -preset veryfast \ -filter_complex ${xfade} \ ${outputFile} But I have a major and minor problem. The major problem is that I do not have audio from the second part of the video. The minor problem is that I have to calculate the offset. It would be nice if I could use -duration, but that does not work sadly. By the way: how should I do it when I want to use five parts of the video? -- Cecil Westerhof Senior Software Engineer LinkedIn: http://www.linkedin.com/in/cecilwesterhof _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
