@subsection Options @subsection Options
@table @option @table @option
@item profile
Set the encoding profile.
@item level
Set the operating point level.
@item tier
Set the operating point tier.
@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 @item qmax
Sets the maximum quantizer to use when using bitrate mode. Set the maximum quantizer to use when using a bitrate mode.
@item qmin @item qmin
Sets the minimum quantizer to use when using bitrate mode. Set the minimum quantizer to use when using a bitrate mode.
@item qp @item qp
Uses quantizer mode to encode at the given quantizer (0-63). Set the quantizer used in cqp rate control mode (0-63).
@item hielevel @item sc_detection
Enable scene change detection. Enable scene change detection.
@item la_depth @item la_depth
Set number of frames to look ahead (0-120). Set number of frames to look ahead (0-120).
@item preset @item preset
Set encoding preset. Set the quality-speed tradeoff, in the range 0 to 8. Higher values are
faster but lower quality. Defaults to 8 (highest speed).
@item tier @item tile_rows
Set log2 of the number of rows of tiles to use (0-6).
@item tile-rows @item tile_columns
Selects how many rows of tiles to encode with (0-6). Set log2 of the number of columns of tiles to use (0-4).
@item tile-columns
Selects how many columns of tiles to encode with (0-4).
