       | outputs, like this one:

       | Not sure I remember what the bug was (probably some
       | overflow/clipping issues when dealing with 8 bit numbers) but the
       | original image (above) was unprocessed frame from a movie (I
       | don't remember which one).
       | 
       | Once the bug was fixed, there was little difference (except for
       | the blocking effect of quantization). Was quite surprised how
       | such a small bug creates such drastic visual difference.
