[FFmpeg-user] Problem reducing resolution

[Tim Kinnel]

I am using ffmpeg to convert video from mov to mp4 and to reduce the resolution from 640x360 to 320x180. However, the video comes out at 480x270. I am using the following command:

ffmpeg -y -i "source.mov" -vcodec libx264 -s 320x180 -b 1000k -r 15 -vpre slow_firstpass -an "output_320x180.mp4"

Does anyone have any hints about what might be going on? Thanks!

Cheers,
Tim
