[FFmpeg-user] lbavfilter. watermark. time interval.

I'm currently working with libavfilter and have a question relating watermarks.
What I already know is how to put a watermark on a whole video clip.
ffmpeg -i inputfile -vf "movie=650_360_net.png [logo]; [in][logo] overlay=W-
w-20:H-h-20 [out]" outpufile
What I'm trying to achieve is to place a watermark that would only be visible
from some certain point and to some point - for example, only the first 10
seconds of the video clip.
If there's a workaround that can make it possible please let me know. I'm
stuck on this issue right now so I would be glad to receive an answer.
Thanks in advance.
