(close, even > for wide values of close, would be fine) I switched to -c because I needed split-second accuracy, but if you don't, try --frame_interval. It may even be frame-accurate now. transcode -q 0 -o $DDIR/$FIL.img -y im -F png -x ffmpeg,null -i $DDIR/$FIL.dv --frame_interval 900 2> /dev/null If you try, let us know what performance you get.
