Resolution limit?
on Jun 4, 2012 at 10:10:39 pm

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

Weird. You could try using libavfilter to do it: -vf scale="320:180"

Thanks for the suggestion, which I tried. Same result.
