@item high
@end table
@item rc
Set the rate control mode to use.
Possible modes:
@table @option
@item cqp
Constant quantizer: use fixed values of qindex (dependent on the frame type)
throughout the stream. This mode is the default.
@item vbr
Variable bitrate: use a target bitrate for the whole stream.
@item cvbr
Constrained variable bitrate: use a target bitrate for each GOP.
@end table
@item qmax
Set the maximum quantizer to use when using a bitrate mode.
@item qmin
Set the minimum quantizer to use when using a bitrate mode.
@item crf
Constant rate factor value used in crf rate control mode (0-63).
@item qp
Set the quantizer used in cqp rate control mode (0-63).

Set number of frames to look ahead (0-120).
@item preset
Set the quality-speed tradeoff, in the range 0 to 8. Higher values are
faster but lower quality. Defaults to 8 (highest speed).
Set the quality-speed tradeoff, in the range 0 to 13. Higher values are
faster but lower quality.
@item tile_rows
Set log2 of the number of rows of tiles to use (0-6).
