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 quality=<number> (0.0..10.0, default: 3.0) VBR Quality (10: best) Quality for VBR mode 10: best (largest output file) 0: worst (smallest output file) min_bitrate=<number> (0..1000, default: 0) Minimum bitrate (kbps) Optional minimum bitrate (in kbps) 0 = unspecified 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.

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 over‐ sized; 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 here -o <output_options> Set output options output_directory=<string> (Default: .)
