[libav-tools] insert a logo with transparency

Hello, this is the command I am using

avconv -loglevel error -i video1.avi -vf "movie=logo.png [logo]; [in][logo]
overlay=W-w-10:10:1[out]" -vcodec libx264 -acodec libmp3lame -b 1400k -b:a
192k outlogov1.avi

For a transparent png, it works, but it doesn't for a bmp.
Is there a way to do that? (as GIMP for instance)

Thanks and regards
