I am using "-copyts" to maintain the input timestamps at the output side. Thus, I believed that using "-ss 60 -t 10" with "-copyts" was supposed to mean "take seconds 60-70 of input_clip_x264_offset as input and produce 60-70 of the resultant stream". >> "select=between(t\,60.000\,70.000)" > > "only keep frames between seconds 60 and 70" > > Since [0;10[ \cup [60;70[ = \emptyset, the result you observe is > expected. If "-ss 60 -t 10" is able to produce output in the rage [60;70[ at the output side, then the select filter will appropriately select only those timestamps. Please let me know if my understanding is right. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
