bash strerr pipe problem - workaround ?

I have a app that outputs to stderr, what I need is a filtered version
to be saved in a file
motion -c %s/core/motion_conf/motion.conf 2> saved
works as expected but is unfiltered. So to filter it I am trying ...
motion -c %s/core/motion_conf/motion.conf | grep -E 'error|not found' > saved
and I get zip. I am thinking because stderr gets dumped to screen and
not processed by the pipe
motion is continuously running so I cannot use motion -c
%s/core/motion_conf/motion.conf 2> saved
then filter the output, it has to be an ongoing process.
Any ideas how to get around this ?
