How to scale and position watermark to scale?

Question

I\'m scaling a video and applying a watermark like so:

ffmpeg -ss 0:0:0.000 -i video.mp4 -y -an -t 0:0:10.000
 -vf \\\"[in]scale=400:316[middle]\\\" -b:v 200

Answered by ubitux on the FFmpeg IRC:

Use scale and overlay in a single -filter_complex chain, like so:

ffmpeg -y -ss 0 -t 0:0:30.0 -i 'video.mp4' -i '/watermark.png'
 -filter_complex "[0:0] scale=400:225 [wm]; [wm][1:0] overlay=305:0 [out]"
 -map "[out]" -b:v 896k -r 20 -an 
 'out.flv'

Also load the watermark via -i rather than the movie filter.
