[transcode-users] Intermittent thumbnails?

[David Liontooth]

I'd like to create thumbnails every ten seconds from a video. This works
for a continuous series:

    transcode -o thumb -y ppm,null -y im -F png -x ffmpeg,null -i
dx50.avi -c 0:0:0-0:0:01

Is there a way to set -c so that I get one frame every ten seconds?
