Managed: You specify a nominal bitrate and (optionally) a minimum
and maximum bitrate
VBR is recommended, managed bitrate might result in a worse quality

format=<string>
Supported strings: mpeg1 vcd mpeg2 svcd dvd_nav dvd
Default: mpeg1
Format
Output format. Note that for some output formats (e.g. VCD), you MUST
use proper settings for the audio and video streams also, since this
isn't done automatically
tmp_dir=<string> Directory for temporary files Leave empty to use the same directory as the final output file
aux_stream_1=<string> Additional stream 1 Additional stream to multiplex into the final output file. Use this if you want e.g. create mp3 or AC3 audio with some other encoder
aux_stream_2=<string> Additional stream 2 Additional stream to multiplex into the final output file. Use this if you want e.g. create mp3 or AC3 audio with some other encoder
aux_stream_3=<string> Additional stream 3 Additional stream to multiplex into the final output file. Use this if you want e.g. create mp3 or AC3 audio with some other encoder

format=<string> Supported strings: mpeg1 mpeg2 vcd svcd dvd Default: mpeg1 Format Sets the MPEG flavour. Note, that for VCD, SVCD and DVD, you MUST provide valid frame sizes
bitrate_mode=<string> 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 option is ignored
bitrate=<number> (200..99999, default: 1150) Bitrate (kbps) Video bitrate in kbps. For VBR, it's the maximum bitrate. If the format requires a fixed bitrate (e.g. VCD) this option is ignored

quant_matrix=<string> Supported strings: default kvcd tmpgenc hi-res Default: default Quantization matrices bframes=<number> (0..2, default: 0) 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.

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
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

-
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 nframes=<number> (1..10, default: 1) 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
target_bitrate=<number> (45..2000, default: 250) Target bitrate (kbps) quality=<number> (0..63, default: 10) Nominal quality 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 here

selecting the encoder mode.
