Copyright (C) Microsoft Corporation. All rights reserved.


Encode from files or devices to Windows Media files or streams. Supported
source file formats are .wmv, .wma, .asf, .avi, .wav, .mpg, .mp3, .bmp,
.jpg, and .avs.


Usage for I/O and statistics.
-----------------------------

[-wme] <Windows Media Encoder session file>
    Loads an existing Windows Media Encoder session file.
[-input] <file or directory name>
    The file or directory to be encoded.
    Specify a file or directory name. If you specify a directory, supported
    files in the directory will be encoded to the output directory, using
    the same encoding settings. 
    Enclose file and directory names that have spaces in quotations.
    For example: -input "c:\my sample.wmv"
[-output] <file or directory name>
    The name of the output file or directory.
    If the input is a file, -output corresponds to a file name. If the input
    is a directory, -output corresponds to a directory name.
    The output directory will be created if it doesn't already exist.
    An extension is automatically appended to output files.
    (.wma for audio-only Windows Media files, and .wmv for video-only or
    audio and video Windows Media files.)

Usage for audio settings.
-------------------------

[-a_input]
    Sets a separate input file to be used as audio source when encoding
    to a .wmv containing both video and audio streams.
    Must use -input to also specify the video source, otherwise -a_input
    will be ignored. Audio source defined by -a_input will override any
    audio stream present in the main -input source.
    Enclose file names that have spaces in quotations.
    For example: -a_input "c:\my sample.wav"
[-a_codecs]
    Lists all available audio codecs.

    WMASTD:  Windows Media Audio (default).
    WMAPRO:  Windows Media Audio Professional.
    WMALSL:  Windows Media Audio Lossless.
    WMSP:    Windows Media Audio Voice.
    PCM:     No compression.

    Legacy indexes WMA9STD, WMA9PRO, WMA9LSL and WMSP9 will translate
    to new version-agnostic indexes.
[-a_mode] <mode>

    2 = Mixed (speech and music) mode (also requires -a_contentedl)
    You must also specify the Windows Media Audio Voice codec.
[-a_contentedl] <file name>
    Specifies the places in audio content where music starts and ends. To do
    this, you must first create an optimization definition file. You
    must specify the Windows Media Audio Voice codec and -a_content 2 when
    when you use the -a_contentedl option.
[-a_folddown6to2] <surround mix> <center mix> <LFE>
    Fold-down coefficients for multichannel audio. Use whole numbers only.

    Buffer in msec for audio with peak bit rate-based VBR. If not specified,
    the default of 3000 msec is used.
[-a_setting] <setting>
    Specifies the formats for audio setting.
    Use -a_formats to list supported audio formats for each codec.

    -a_setting Bitrate_SamplingRate_Channels. For example, -a_setting 48_44_2
    specifies 48 Kbps, 44 kHz, and two channels. The default is 64_44_2.

    If you use quality-based VBR: -a_setting Qxx_SamplingRate_Channels.
    For example, -a_setting Q90_44_2 specifies a quality level of 90, 44 kHz,
    and 2 channels.

    If you use the Windows Media Audio Professional codec:
    -a_setting Bitrate_SamplingRate_Channels_BitDepth.
    For example, -a_setting 250_44_2_24 specifies 250 Kbps, 44 kHz, 
    two channels, and 24-bit encoding. Use either 16- or 24-bit encoding.
    24-bit is the default.

    If you use the Windows Media Audio Lossless codec:
    -a_setting Qxx_SamplingRate_Channels_BitDepth. For example,
    -a_setting Q100_44_2_24 specifies VBR Quality 100, 44 kHz, two channel,
    24-bit encoding. (Quality-based VBR and a quality level of 100 is
    required with this codec.)

        For example, 640x480x30 interlace to 640x480x30 progressive.
        The encoder uses a simple field blending deinterlace method which
        produces good quality in still scenes but might result in ghosting
        or blurring in high motion scenes.

    17: Interlaced encoding - First field is top field.
    18: Interlaced encoding - First field is bottom field.
[-v_clip] <left> <top> <right> <bottom>
    The region of the image (with respect to source) to be clipped/encoded.
    If the right is 0 or greater than width, it is ignored and re-assigned
    to width. If the bottom is 0 or greater than height, it is ignored and
    re-assigned to height.
[-v_bitrate] <bit rate>
    Video bit rate in bits per second to be encoded. Default: 250000 bps.
    Set this to 0 for audio-only coding.
[-v_buffer] <buffer>
    Delay buffer in milliseconds for video. Default: 5000 msec.
[-v_quality] <quality>
    CBR: Quality/smoothness tradeoff. 0 to 100, 0 being the smoothest.
    Higher values might drop frames in order to maintain image quality.
    Default: 75.
    Quality-based VBR: Image quality for the video. Encode video to the
    specified quality, regardless of bit rate. Default: 95.
    In 2-pass modes the quality parameter is ignored.
[-v_qp] <quantizer parameter>
    An alternative method of specifying image quality in quality-based VBR
    mode. Because quality-based VBR uses a fixed QP for all encoded frames,
    this method allows direct mapping to QP levels. Valid range is 1.0 to
    31.0 in 0.5 intervals. Default: 2.5
    If v_quality is also specified it will override v_qp.
[-v_peakbitrate] <peak bit rate>
    Peak bit rate in bits per second for peak bit rate-based VBR for video.
    If not specified, the peak bit rate is 1.5 times the video bit rate.
[-v_peakbuffer] <peak buffer>
    Buffer in msec for video, with peak bit rate-based VBR. If not specified,
    the default of 5000 msec is used.
[-v_performance] <performance level>
    Sets the encoder performance/quality level. Possible values: 0, 20, 40,
    60, 80, and 100, where 0 is fastest and 100 is highest quality. If you
    do not specify a value, codec defaults are used.
    Default: 60 (WMV9 and WVC1).
[-v_complexity] <complexity level>
    Same as v_performance but expressed on a scale from 0 to 5.
    If v_performance is also specified it will override v_complexity.
[-v_profile] <conformance profile>
    Sets the VC-1 conformance profile for the encoded video. Video profiles
    are used to indicate the decoding complexity of the video, as well as to
    indicate which features a decoder needs to have implemented in order to
    correctly decode the video. In order to stay conformant to the requested
    profile, the encoder might ignore certain advanced WMV settings.
    Possible values for WMV9 codec are SP (Simple) and MP (Main). WVC1 codec
    only allows AP (Advanced) value.
    If you do not add the -v_profile option to a command, the correct profile
    level is selected automatically during encoding.
[-pixelratio] <x y>
    Specifies the video pixel aspect ratio. Common pixel aspect ratios:
    DV NTSC fullscreen    10:11
    DV NTSC widescreen    40:33
    DV PAL fullscreen     12:11
    DV PAL widescreen     16:11

    Dquant allows macroblocks containing smooth or dark areas to be encoded at
    a quantizer level lower than the rest of the image.
    0: Off (default).
    1: Apply to I frame only.
    2: Apply to I and P frames.
    3: Apply to I, P and B frames.

    3: Fixed QP dquant method for dark areas (QP 1).
    4: Regular dquant method for dark areas.
[-v_adz] <strength>
    Controls adaptive dead-zone, a quantization method which attempts to
    balance the bit distribution within a picture between smooth areas with
    fine details and textured areas with coarse details. Increasing the
    strength controls how aggressively areas are mapped to larger dead-zones
    where image detail is irretrievably lost.
    Valid range is 0 to 15, where 0 (default) disables the ADZ option.
    Using high values can result in loss of too much image detail.
[-v_loopfilter] <setting>
    Controls the in-loop deblocking filter. This filter reduces blocking
    artifacts at encoding time so that future P and B frames don't carry
    forward the blocking artifacts. If not specified, loop filter is
    enabled by default at resolutions below standard definition (SD).
    0 to disable, 1 to enable.
[-v_overlap] <setting>

    and grain when performing motion estimation which can improve video
    quality in very noisy video but can adversely affect clean video.
    0 to disable (default), 1 to enable.
[-v_scaling] <setting>
    Specifies whether to scale the luma range before encoding in order to
    improve efficiency. Scaled luma range is not expanded when decoded.
    0: Off (default).

    2: Aggressive. Compresses Y range to 31..224.
[-v_edgeremoval] <setting>
    Specifies whether encoder should attempt to detect and remove noisy
    frame edges, such as VBI data often found in broadcast television.
    0 to disable (default), 1 to enable.

    0: Macroblock-adaptive.
    1: SAD (default).
    2: Hadamard.
[-v_mbmodecost] <method>
    Specifies the cost method used to decide the macroblock mode.
    0: SAD/Hadamard (default when v_performance < 60).
    1: Rate Distortion (default when v_performance > 40).
[-v_mvcoding] <method>
    Specifies the method used to code delta motion vectors in interlaced
    images. Wider motion vector distributions are more efficient at storing
    random motion within a frame.
    0: Default delta motion vector distribution size.
    1: Double horizontal delta motion vector distribution size.
    2: Double vertical delta motion vector distribution size.
    3: Double delta motion vector distribution size in both directions.
[-v_mvcost] <method>
    Specifies the motion vector cost method.
    0: Fixed motion vector cost.
    1: Adaptive motion vector cost (default).
[-v_bframedist] <frames>
    Specifies the number of bidirectional predictive (B) frames that the
    encoder will use between other types of frames.
    If not specified, the encoder will only use I and P type frames.
    Valid range is 0 to 7, where 0 indicates that B-frames will not be used.
[-v_bdeltaqp] <delta>
    Sets the fixed increase between the anchor frame's picture quantizer level
    and the B frame's picture quantizer level. Valid range is 0 to 31. If not
    specified, the encoder will use variable deltas.
[-v_lookahead] <frames>
    Sets the number of frames to evaluate ahead for ratecontrol optimization.
    Enabling lookahead might automatically insert B frames into the video in
    place of flash frames. To completely disable B frame insertion, also set
    -v_bframedist to 0. Lookahead is ignored in 2-pass ratecontrol modes.
    Valid range is 0 to 16, where 0 disables the lookahead option.
[-v_rangeredux] <Y reduction> <Y expansion> <C reduction> <C expansion>
    Forces range reduction for the luma (Y) and chroma (C) channels. Reduced
    range is then expanded on decode by the set expansion factor.
    Reducing the color/luma range reduces the encoded size of video frames,
    but can introduce banding artifacts in the decoded frames.
    Valid range for each reduction/expansion factor is 0 to 8.
[-v_codedwidth] <width>
    Encodes video at a width different than the decoded display width.
    Valid range is 32 to 8192. Values will be rounded up internally to the
    nearest multiple of 32.
[-v_codedheight] <height>
    Encodes video at a height different than the decoded display height.
