Hello Nicolas, Thank you for the reply. I've now tried adding the "-s:s 720x576" option as you suggested but the result has not changed. Is the position significant? The command is now: ffmpeg -i Suburgatory-20121110-1024.TS -s:s 720x576 -filter_complex "[0:v][0:s]overlay" -sn sub.mkv The canvas does not appear to have changed size and I still get the "sub2video: rectangle overflowing" messages. The output contains: [mpegts @ 000000000068fa60] sub2video: using 704x576 canvas Having found the "-s" option in the documentation I wonder if the optiononly applies to video streams? Many thanks, Stuart
