+@section libsvt-av1
+
+Scalable Video Technology for AV1 (SVT-AV1) encoder wrapper.
+
+This encoder requires the presence of the headers and
+library during configuration. You need to explicitly configure the
+build with @code{--enable-libsvtav1enc}. The library is detected using
+@command{pkg-config}.
+
+For more information about the library see
+@url{https://github.com/OpenVisualCloud/SVT-AV1}.
+
+@subsection Options
+
+The following FFmpeg global options affect the configurations of the
+libsvt-av1 encoder:
+
+@table @option
+@item b  (@emph{bitrate})
+Set the bitrate (as a number of bits per second). Default is 7M.
+
+@item g  / @option{gop_size}
+Set the GOP size. Default is -2 (unspecified).
+
+@item qmin (@emph{min-q})
+Default is 0
+
+@item qmax (@emph{max-q})
+Default is 63
+
+Set minimum/maximum quantisation values.  Valid range is from 0 to 63
+(Only used when bit rate control mode @option{rc} is set to 2(vbr) mode.
+It is required that qmax >= qmin).
+
+@item threads
+Set the number of threads to use while encoding. if not set, threads will be
+managed by OS thread scheduler.
+
+@item profile (@emph{profile})
+Set profile restrictions. Can assume one of the following possible values:
+
+@table @samp
+@item main
+main profile
+@item high
+high profile
+@item professional
+professional profile
+@end table
+
+Default is 0 (main), but may be modified as pixel format to follow AV1 specification
+
+@item level (@emph{level})
+
+@option{level} sets the value of @emph{level}.
+Set level (level_idc). Default is 0 (to be determined by libsvt av1 library).
+
+@end table
+
+The encoder also has its own specific options:
+
+@table @option
+@item hielevel
+Set hierarchical levels. Can assume one of the following possible values:
+
+@table @samp
+@item 3 level
+Minigop size is 2^3
+@item 4 level
+Minigop size is 2^4
+@end table
+
+Default is 4 level.
+
+@item la_depth
+Set look-ahead depth, depending on @option{rc}: for @var{vbr}, it's recommended
+to unset it and use the default value (the intra period); for @var{cqp}, better
+specify the look-ahead depth.
+
+The range is @var{-1-120}. Default is -1 (unset and the default value to be used).
+
+@item preset
+Set the quality vs density tradeoff point at which the encoding is to be performed.
+Higher perset value, higher density and lower quality.
+
+The range is @var{0-8}. Default is 8.
+
+@item tier
+Set @emph{general_tier_flag}.  This may affect the level chosen for the stream
+if it is not explicitly specified. Can assume one of the following possible values:
+
+@table @samp
+@item main
+main tier
+@item high
+high tier
+@end table
+
+Default is 0 (main).
+
+@item rc
+Set bit rate control mode. Can assume one of the following possible values:
+
+@table @samp
+@item cqp
+Constant QP (CQP) mode
+@item vbr
+Variable Bit Rate (VBR) mode
+@end table
+
+Default is 2 (vbr).
+
+@item qp
+Initial quantization parameter for the intra pictures used when
+@option{rc} is cqp mode. The range is from @var{0-63}. Default is 50.
+
+@item sc_detection
+Enables or disables the scene change detection algorithm. Default is 0 (disabled).
+
+@item bl_mode
+Enables or disables Random Access Prediction. Default is 0 (disabled).
+@end table
+
+@subsection Examples
+
+@itemize
+@item
+Set VBR mode with 5Mbps with @command{ffmpeg}:
+@example
+ffmpeg -i INPUT -codec:v libsvt-av1 -rc vbr -b:v 5M OUTPUT.mp4
+@end example
+
+@item
+Set CQP mode with qp equal to 30 with @command{ffmpeg}:
+@example
+ffmpeg -i INPUT -codec:v libsvt-av1 -rc cqp -qp 30 OUTPUT.mp4
+@end example
+@end itemize
