I suggest to use a separate ffmpeg command to cut each segment (with -ss/-t/-to) and use fade/afade start time and duration options. Then use the concat muxer to concatenate the segments together. Note that at the moment it is not possible to select multiple segments with a single ffmpeg command (e.g. by specifying several seek commands), and [a]select requires the transcoding of the whole file. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
