           Supported strings: auto vbr cbr

           Default: auto

           Bitrate Mode

           Specify constant or variable bitrate. For "Auto", constant bitrate will  be  used  for
           MPEG-1, variable bitrate will be used for MPEG-2. For formats, which require CBR, this

           Bitrate (kbps)

           Video bitrate in kbps. For VBR, it's the maximum bitrate. If  the  format  requires  a

           Minimum  quantization for VBR. Lower numbers mean higher quality. For CBR, this option

           Number of B-Frames

           Specify the number of B-frames between 2 P/I frames. More B-frames slow down  encoding
           and  increase  memory  usage, but might give better compression results. For VCD, this
           option is ignored, since the VCD standard requires 2 B-frames, no matter if  you  like
           them or not.

           Maximum keyframe interval

           drop_frames=[1|0] (default: 1)

           Enable frame dropping

           Drop frames to keep within bitrate buffer constraints. This can have a  severe  impact
           on  quality,  but  is the only way to ensure that bitrate targets are met at low rates
           during sudden bursts of activity.

           cap_overflow=[1|0] (default: 1)

           Don't bank excess bits for later use

           Ignore bitrate buffer overflows. If the encoder uses so few bits that the reservoir of
           available  bits  overflows,  ignore  the excess. The encoder will not try to use these
           extra bits in future frames. At high rates this may cause the result to be undersized,
           but  allows  a  client to play the stream using a finite buffer; it should normally be
           enabled.

           cap_underflow=[1|0] (default: 0)

           Don't try to make up shortfalls later

           Ignore bitrate buffer underflows. If the encoder uses so many bits that the  reservoir
           of  available bits underflows, ignore the deficit. The encoder will not try to make up
           these extra bits in future frames. At low rates  this  may  cause  the  result  to  be
           oversized; it should normally be disabled.

           speed=<number> (0.00..1.00, default: 0.00)

           Encoding speed

           Higher  speed levels favor quicker encoding over better quality per bit.  Depending on
           the encoding mode, and the internal algorithms used, quality may actually improve, but
           in  this  case bitrate will also likely increase. In any case, overall rate/distortion
           performance will probably decrease.

           default_timescale=<number> (default: 25)

           Default timescale

           Suboptions for codec=vorbis

             bitrate_mode=<string>

             Supported strings: vbr vbr_bitrate managed

             Default: VBR

             Bitrate mode

             Bitrate mode: VBR: You specify a quality and  (optionally)  a  minimum  and  maximum
             bitrate  VBR (bitrate): The specified nominal bitrate will be used for selecting the
             encoder mode.  Managed: You specify a nominal bitrate and (optionally) a minimum and
             maximum bitrate VBR is recommended, managed bitrate might result in a worse quality

             nominal_bitrate=<number> (0..1000, default: 128)

             Nominal bitrate (kbps)

             Nominal bitrate (in kbps) for managed mode

             max_bitrate=<number> (0..1000, default: 0)

             Maximum bitrate (kbps)

             Optional maximum bitrate (in kbps) 0 = unspecified

           Suboptions for codec=speex

             mode=<string>

             Supported strings: auto nb wb uwb

             Default: auto

             Speex mode

             Encoding mode. If you select Auto, the mode will be taken from the samplerate.

             quality=<number> (0..10, default: 3)

             Quality (10: best)

             complexity=<number> (0..10, default: 3)

             Encoding complexity

             Frames per Ogg packet

             bitrate=<number> (0..128, default: 8)

             Bitrate (kbps)

             Bitrate  (in  kbps).  Set  to  0 for seleting the standard bitrates for the encoding
             mode.

             vbr=[1|0] (default: 0)

             Variable bitrate

             abr_bitrate=<number> (0..128, default: 0)

             Average bitrate (kbps)

             Average bitrate (in kbps). Set to 0 for disabling ABR.

             vad=[1|0] (default: 0)

             Use voice activity detection

             dtx=[1|0] (default: 0)

             Enable file-based discontinuous transmission

           cbr=[1|0] (default: 0)

           Use constant bitrate

           For constant bitrate, choose a target bitrate. For variable bitrate, choose a  nominal
           quality.

           target_bitrate=<number> (45..2000, default: 250)

           Target bitrate (kbps)

           quality=<number> (0..63, default: 10)

           Quality for VBR mode 63: best (largest output file) 0:  worst (smallest output file)

           max_keyframe_interval=<number> (1..1000, default: 64)

           Maximum keyframe interval

           drop_frames=[1|0] (default: 1)

           Enable frame dropping

           Drop  frames  to keep within bitrate buffer constraints. This can have a severe impact
           on quality, but is the only way to ensure that bitrate targets are met  at  low  rates
           during sudden bursts of activity.

           cap_overflow=[1|0] (default: 1)

           Don't bank excess bits for later use

           Ignore bitrate buffer overflows. If the encoder uses so few bits that the reservoir of
           available bits overflows, ignore the excess. The encoder will not  try  to  use  these
           extra bits in future frames. At high rates this may cause the result to be undersized,
           but allows a client to play the stream using a finite buffer; it  should  normally  be
           enabled.

           cap_underflow=[1|0] (default: 0)

           Don't try to make up shortfalls later

           Ignore  bitrate buffer underflows. If the encoder uses so many bits that the reservoir
           of available bits underflows, ignore the deficit. The encoder will not try to make  up
           these  extra  bits  in  future  frames.  At  low rates this may cause the result to be
           oversized; it should normally be disabled.

           speed=<number> (0.00..1.00, default: 0.00)

           Encoding speed

           Higher speed levels favor quicker encoding over better quality per bit.  Depending  on
           the encoding mode, and the internal algorithms used, quality may actually improve, but
           in this case bitrate will also likely increase. In any case,  overall  rate/distortion
           performance will probably decrease.

           default_timescale=<number> (default: 25)

           Default timescale

           For formats, which support only constant framerates, set the default timescale here

           default_frame_duration=<number> (default: 1)

           Default frame duration

           For  formats,  which  support only constant framerates, set the default frame duration
