Raising their frequency usually improves quality.
Sets maximum interval between I frames.
Larger values save bits, thus improve quality, at the cost of seeking
precision (default: 60).

Number of previous frames used as predictors in a P-frame (default: 1).
This may cause tiny changes in bitrate and PSNR.

Number of previous frames used as predictors in a P frame (default: 1).
This is effective in Anime, but seems to make little difference in
live-action source material.
Some decoders are unable to deal with large frameref values.
