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: 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

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.
