method suggested in SMPTE 314M Table 22, and an improved
method. The SMPTE method is very conservative; it assigns class
3 (i.e. severe quantization) to any block where the largest AC
component is greater than 36. FFmpeg's DV encoder tracks AC bit
component is greater than 36. Libav's DV encoder tracks AC bit
consumption precisely, so there is no need to bias most blocks
towards strongly lossy compression. Instead, we assign class 2
to most blocks, and use class 3 only when strictly necessary
