    Did some digging and found out that:

    AVC (H.264) uses a different quantizer scale (1-51) than most other codecs (1-31)

    Try -qmin 51 -qmax 51

    This should give you the absolute minimum for AVC/H.264/Mpeg4Layer10 video.

    Thanks for that,

    I always got q=31 during conversion, so I assumed that 31 was the highest possible as the videos were the same as the originals. I will try using the q scale as soon as I can.
