First, you should compute the encoded aspect ratio:

On the other hand, it is worthless to raise CQ higher than 0.30 as you would
be wasting bits without any noticeable quality gain.
Also note that as mentioned earlier in this guide, low resolution videos
need a bigger CQ (compared to for ex. DVD-resolution) to look good.
