### Video Options

-e, --encoder <string>

Set video library encoder Options: x264 / ffmpeg4 / ffmpeg2 / theora (default: ffmpeg4)

--x264-preset <string>

When using x264, selects the x264 preset:

ultrafast / superfast / veryfast / faster / fast / medium / slow / slower / veryslow / placebo

--x264-tune <string>

When using x264, selects the x264 tuning:

film / animation / grain / stillimage / psnr / ssim / fastdecode / zerolatency

-x, --encopts <string>

Specify advanced encoder options in the same style as mencoder (x264 and ffmpeg only): option1=value1:option2=value2

--x264-profile <string>

When using x264, ensures compliance with the specified h.264 profile:

baseline / main / high / high10 / high422 / high444

-q, --quality <number>

Set video quality

-b, --vb <kb/s>

Set video bitrate (default: 1000)

-2, --two-pass

Use two-pass mode

-T, --turbo

When using 2-pass use the turbo options on the first pass to improve speed (only works with x264, affects PSNR by about 0.05dB, and increases first pass speed two to four times)

-r, --rate

Set video framerate (5 / 10 / 12 / 15 / 23.976 / 24 / 25 / 29.97 / 30 / 50 / 59.94 / 60) Be aware that not specifying a framerate lets HandBrake preserve a source's time stamps, potentially creating variable framerate video

--vfr, --cfr, --pfr

Select variable, constant or peak-limited frame rate control. VFR preserves the source timing. CFR makes the output constant rate at the rate given by the -r flag (or the source's average rate if no -r is given). PFR doesn't allow the rate to go over the rate specified with the -r flag but won't change the source timing if it's below that rate. If none of these flags are given, the default is --cfr when -r is given and --vfr otherwise

### Audio Options

-a, --audio <string>

Select audio track(s), separated by commas ("none" for no audio, "1,2,3" for multiple tracks, default: first one). Multiple output tracks can be used for one input.

--audio-copy-mask <string>

Set audio codecs that are permitted when the "copy" audio encoder option is specified (aac/ac3/dts/dtshd/mp3, default: all). Separated by commas for multiple allowed options.

--audio-fallback <string>

Set audio codec to use when it is not possible to copy an audio track without re-encoding.

-D, --drc <float>

Apply extra dynamic range compression to the audio, making soft sounds louder. Range is 1.0 to 4.0 (too loud), with 1.5 - 2.5 being a useful range. Separated by commas for more than one audio track.

-Y, --maxHeight <#>

Set maximum height

-X, --maxWidth <#>

Set maximum width

--strict-anamorphic

Store pixel aspect ratio in video stream

### Subtitle Options

-s, --subtitle <string>

Select subtitle track(s), separated by commas More than one output track can be used for one input. Example: "1,2,3" for multiple tracks. A special track name "scan" adds an extra 1st pass. This extra pass scans subtitles matching the language of the first audio or the language selected by --native-language. The one that's only used 10 percent of the time or less is selected. This should locate subtitles for short foreign language segments. Best used in conjunction with --subtitle-forced.

-F, --subtitle-forced <string>

Only display subtitles from the selected stream if the subtitle has the forced flag set. The values in "string" are indexes into the subtitle list specified with '--subtitle'. Separated by commas for more than one subtitle track. Example: "1,2,3" for multiple tracks. If "string" is omitted, the first track is forced.

--subtitle-burned <number>

"Burn" the selected subtitle into the video track If "number" is omitted, the first track is burned. "number" is an index into the subtitle list specified with '--subtitle'.

--subtitle-default <number>

Flag the selected subtitle as the default subtitle to be displayed upon playback. Setting no default means no subtitle will be automatically displayed If "number" is omitted, the first track is default. "number" is an index into the subtitle list specified with '--subtitle'.

-N, --native-language <string>

Specifiy your language preference. When the first audio track does not match your native language then select the first subtitle that does. When used in conjunction with --native-dub the audio track is changed in preference to subtitles. Provide the language's iso639-2 code (fre, eng, spa, dut, et cetera)

--native-dub

Used in conjunction with --native-language requests that if no audio tracks are selected the default selected audio track will be the first one that matches the --native-language. If there are no matching audio tracks then the first matching subtitle track is used instead.

--srt-file <string>

SubRip SRT filename(s), separated by commas.

--srt-codeset <string>

Character codeset(s) that the SRT file(s) are encoded in, separted by commas. Use 'iconv -l' for a list of valid codesets. If not specified latin1 is assumed

--srt-offset <string>

Offset in milli-seconds to apply to the SRT file(s) separted by commas. If not specified zero is assumed. Offsets may be negative.

--srt-lang <string>

Language as an iso639-2 code fra, eng, spa et cetera) for the SRT file(s) separated by commas. If not specified then 'und' is used.

--srt-default <number>

Flag the selected srt as the default subtitle to be displayed upon playback. Setting no default means no subtitle will be automatically displayed If "number" is omitted, the first srt is default. "number" is an 1 based index into the srt-file list
