 HandBrake is an open-source video transcoder available for Linux, Mac, and Windows. Everyone can use HandBrake to make videos *for free*.

-HandBrake is a post-production tool. Its primary purpose is to convert videos from supported [source formats](../technical/source-formats.html) to MP4 or MKV format. If you wish to make changes to your `Source` video, please use an appropriate [video editing software](https://en.wikipedia.org/wiki/List_of_video_editing_software).

 ## What HandBrake does

 HandBrake takes videos you already have and makes new ones that work on your mobile phone, tablet, TV media player, game console, computer, or web browser—nearly anything that supports modern video formats.

-HandBrake works with most common video files and formats, including ones created by consumer and professional video cameras, mobile devices such as phones and tablets, game and computer screen recordings, and DVD and Blu-ray discs. HandBrake leverages tools such as FFmpeg, x264, and x265 to create new MP4 or MKV video files from these `Sources`.

+Container formats
+=================

 Containers are files that wrap around video and audio tracks—indexing and organizing the streams for playback—in addition to providing advanced features, like chapters similar to those on DVDs.

-HandBrake supports two widely supported formats. MKV and MP4 (Sometimes seen as M4v)
+HandBrake creates the widely supported container formats MKV and MP4 (sometimes seen as M4V), in addition to the [WebM](https://www.webmproject.org/) container format, which is subset of MKV.

 ## Features

   - The MP4 format can also be optimized for "fast start" progressive downloads over the Web.

-Video Codecs
+Video codecs
 ============

- 
+The following video codecs are available for encoding in HandBrake.

--   H.264 (x264): For MPEG-4 part 10, also known as H.264/AVC.
+- H.264 (x264):

-    -   This is HandBrakes default encoder. It provides excellent performance,
-        filesizes and quality.
+    - MPEG-4 Part 10, also known as H.264/AVC
+    - Provides excellent quality, performance, and file size
+    - Widely supported by media players, including mobile devices

-    -   It is widely supported by players and mobile devices.
+- H.264 (Intel QuickSync):

--   H.264 (Intel QuickSync): For MPEG-4 part 10, also known as H.264/AVC.
+    - MPEG-4 Part 10, also known as H.264/AVC
+    - Hardware based encoder available on Intel processors with Intel HD Graphics (Haswell or newer series CPUs recommended for best quality and file size)
+    - Very fast with significantly lower CPU usage than software H.264 encoders such as x264
+    - Produces larger (but usually not significantly larger) file sizes and slightly lower quality to an equivalent x264 encode, a trade-off that is typically acceptable, especially on lower performance systems

-    -   Available on Intel processors with Intel HD Graphics.
+- H.265 (x265)

-    -   QuickSync is a hardware based H.264 encoder so is very fast, with
-        significantly lower CPU usage than x264.
+    - MPEG-H Part 2, also known as H.265/HEVC
+    - Successor to H.264/AVC offering higher quality encodes and smaller file sizes
+    - Current strengths of x265 are improved quality and compression for low bit rate encodes, and for ultra high definition content
+    - Significantly slower than software H.264/AVC encoders
+    - Limited device compatibility compared to H.264/AVC, but this is improving rapidly

-    -   Intel Haswell or newer CPU's are recommended as these offer the best
-        results in terms of Quality and Filesize.
+- MPEG-4 (ffmpeg):

-    -   You can typically expect larger (but usually not significantly larger)
-        file sizes and slightly lower quality to an equivilent x264 encode. This
-        is a trade off that is fine for most.
+    - MPEG-4 Part 2, also known as MPEG-4 Visual
+    - Predecessor to H.264/AVC offering fast encoding with lower overall quality than H.264/AVC
+    - Compatible with older devices, inexpensive DVD/flash/network players

--   H.265 (x265): Also known as HEVC
+- MPEG-2 (ffmpeg):

-    -   This is the next generation of encoder that offers even higher quality
-        encodes and better filesizes over H.264
+    - MPEG-2 Part 2, also known as MPEG-2 Visual and H.262
+    - Predecessor to MPEG-4 Visual offering very fast encoding with lower quality than modern codecs
+    - Creates larger files than modern encoders

-    -   Note, encoding to H.265 is a significantly more complicated process, so
-        it is expected to be slower than HandBrake's H.264 encoders.
+- VP9 (libvpx):

-    -   Playback support is rather limited at the moment, particularly with
-        mobile devices but this should improve drastically throughout 2015/16
+    - Developed by Google and the successor to VP8, VP9 is a free and open video codec
+    - Comparable to HEVC/H.265 in quality and file size
+    - Slower encoding compared to x265

--   MPEG-4 (ffmpeg): HandBrake offers FFmpeg's MPEG-4 part 2 encoder for fast,
-    low quality encoding.
+- VP8 (libvpx):

-    -   Better support from older devices such as DVD players and cheap "MP4
-        Players"
+    - Developed by On2 Technologies and acquired by Google, VP8 is a free and open video codec
+    - Successor to Theora offering significant improvements, comparable to H.264/AVC

-    -   Lower quality than the H.264 encode option but typically faster encodes.
+- Theora:

--   MPEG-2 (ffmpeg): HandBrake offers FFmpeg's MPEG-2 part 2 encoder for fast,
-    low quality encoding.
-
-    -   Fast Encoding, but requires larger files than MPEG-4 for the same
-        quality level. Useful for testing but not much else.
-
--   VP8 (Libvpx):
-
-    -   A free and open video codec which offers significant improvements over
-        Theora.
-
--   VP3 (Theora): HandBrake can also encode Theora video. Theora video with
-    Vorbis audio in the Matroska container represents a truly free option for
-    multimedia encoding.
-
-    -   However, Theora has yet to reach maturity when measured by quality at a
-        given bitrate.
+    - Developed by Xiph.Org Foundation and based on On2 Technologies' VP3, Theora is a free and open video codec
+    - Comparable to MPEG-4 Visual in quality and file size

-Video Encoding Speed
-=============================
-
-## How is encoding speed measured?
-
-The speed at which your source is encoded is measured in frames per second (fps). That is, how many still images from your video are encoded each second?
-So for example, if your encode is running at 100fps, and your source is a 25fps PAL DVD, then your encoding at 4x real time.
-
-
-## What affects encoding speed?
-
-There are many factors what affect encode performance. The hardware you are running on, the encoder settings you choose and source file itself.
-
-### Hardware
-
-The hardware you run on can have a large effect on performance. HandBrake can scale well up to 6 to 8 CPU cores with diminishing returns thereafter.
-So a 4 core CPU can be nearly twice as fast as a dual Core equivalent, however a 16 core may not be twice as fast as an 8 core but may still offer significant increases in performance. 
-The CPU scaling curve does vary greatly by source and settings used.
-
-HandBrake also supports encoding in ASIC hardware with Intel QuickSync, Nvidia NVEnc, and AMD VCE.
-
-See our [System Requirements](../technical/system-requirements.html) for details on recommended hardware for running HandBrake.
-
-### Settings
-
-Settings play a large part in encoding performance.  Most of the encoders expose many configuration options which allow you to tune the encoders. In HandBrake we've simplified this to a "Video Preset" slider. This offers a range of presets from Ultrafast to Placebo (which is very slow).  This slider trades off speed vs quality and file size. Using faster presets and reduces quality OR increase file size. Using slower presets uses more complex algorithms to compress the video which takes more time offering an overall better result.
-
-For x264 and x265, the Medium preset is a good trade off between quality, file size and speed but you can adjust this slider to suit your needs.

-![HandBrake's Video Quality Settings](../../images/windows/video-quality-1.0.0.png "HandBrake's Video Quality Settings")
-
-<!-- /.system-windows -->
-
-
-Filters are another thing that has a big effect. Particularly if you use Denoise NLMeans. This is a very memory intensive operation so can drastically slow your encodes down. Again, there are settings for the filters that tune them for speed vs quality so you can see widely different results depending on what preset / tune you use.
-
-<!-- .system-windows -->
-
-![HandBrake's Video Filter Settings](../../images/windows/video-filters-1.0.0.png "HandBrake's Video Filter Settings")
-
-<!-- /.system-windows -->
-
-### Source
-
-Your source will have an effect on performance in several ways.
-For example, a 1080P HD video will take longer to encode using the same settings and hardware than a 576P file.  This is because there are 5 times as many pixels to process in the 1080P file.
-Another aspect that can affect performance is what the format of the input file is. For example the H.264 decoder is highly optimised but lesser used codecs may not be so well optimised.  Within a codec, Baseline H.264 will be far quicker and less CPU intensive to decode than High Profile H.264. This is because the decoding algorithms used are simpler, thus, you have more CPU time to spend on encoding.

+Please note, these are not hard limits. Hardware encoding via Nvenc *might* work on older series GPUs and older operating systems, but this is not officially supported.

-Enabling support
---------------
-Support for the NVEnc encoder can be enabled in preferences under the video tab. If your system is not supported, the option will be greyed out.
+## Enabling support

+Support for the Nvidia Nvenc encoder is enabled in preferences on the video tab. If your system is not supported, the option will be disabled.

-Performance
---------------
-Take note that only the encode portion of the encode pipeline is done on the Nvidia ASIC hardware. 
-Every stage prior and after in the pipeline including (decoding, filters, a/v sync, muxing etc.) all happen on the CPU. As a result, it is normal to have high, or 100% CPU utilisation during encodes. 
+## Performance

-It is common, particularly on lower end hardware that the CPU may be a bottleneck for the Nvidia encoder. To minimise this effect, turn off any filters that you do not require.

-Intel Quick Sync Video Advanced Configuration
-==========================
+CLI guide
+=========

-Using the Advanced Options
---------------
-
-From the command line, you can use the --encopts parameter as follows:
-
-   --encopts="option1=value1:option2=value2"
-
-
-From the graphical user interface, just set the options in the dedicated text box:
-
-   option1=value1:option2=value2
-
-Option Types
---------------
-The following value types are supported (each option only accepts one value type):
-
-- integer
-  A number that can be written without a fractional or decimal component.
-
-- float
-  The finite decimal representation of a real number.
-
-- boolean
-  0 means off (or disabled).
-  1 means on (or enabled).
-
-Available Options
---------------
-
-- target-usage (or tu) <integer>
-  - Sets the trade-off between quality and speed, from 1 (best quality) to 7 (best speed).
-  - Default: 2
-
-- num-ref-frame (or ref) <integer>
-  - Number of reference frames, from 1 to 16.
-  - 0 means unspecified (set at runtime by the implementation).
-  - Default: 0 (unspecified)
-
-- gop-ref-dist <integer>  
-  - Distance between I or P reference frames, from 1 to 16.
-  - -1 means automatic (4 in constant QP mode, 3 otherwise).
-  - 0 means unspecified (set at runtime by the implementation).
-  - 1 means B-frames will not be used.
-  - Default: -1 (automatic)
-  - Note: may be sanitized to a lower value in some cases to avoid hangs.
-
-- gop-pic-size (or keyint) <integer>
-  - Number of pictures within the current GOP (aka "keyframe interval").
-  - -1 means automatic (32 in constant QP mode, 1 second long otherwise).
-  - 0 means unspecified (set at runtime by the implementation).
-  - 1 means only I-frames will be used.
-  - 2 means B-frames will not be used.
-  - Default: -1 (automatic)
-
-- cavlc <boolean>
-  - Use CAVLC instead of CABAC entropy coding. Reduces compression efficiency.
-  - It may improve encoding performance slightly, especially on older hardware.
-  - Note: you can also use ''cabac'' (same as ''cavlc'' with reversed meaning).
-  - Default: 0 (CAVLC off, CABAC on)
-
-- b-pyramid <integer>
-  - Enables or disables "Pyramidal B-frames" which can improve compression efficiency.
-  - It may be incompatible with some playback devices (such as the first generation AppleTV).
-  - Note that this options modifies other parameters (gop-ref-dist, num-ref-frame, gop-pic-size).
-  - -1 means automatic (on in constant QP mode, off otherwise).
-  - 0 means off (disabled).
-  - 1 means on (enabled).
-  - Default: -1 (automatic)
-  - Caveats: requires hardware support (4th gen. Intel Core processor or equivalent), and driver support for version 1.6 of the Media SDK API.
-
-- mbbrc <boolean>
-  - Enables macroblock-level bitrate control that generally improves subjective visual quality.
-  - It may have a negative impact on performance and objective visual quality metrics.
-  - Default: 1 (on)
-  - Note: not compatible with Constant QP or !LookAhead rate control methods (ignored).
-  - Caveats: requires hardware support (4th gen. Intel Core processor or equivalent), and driver support for version 1.6 of the Media SDK API.
-
-- extbrc <boolean>
-  - Use extended bitrate control algorithms.
-  - It generally improves objective visual quality metrics and subjective visual quality,
-  - but can also lead to violation of HRD conformance and may significantly reduce performance.
-  - Default: 0 (off)
-  - Note: not compatible with Constant QP or !LookAhead rate control methods (ignored).
-  - Caveats: requires driver support for version 1.6 of the Media SDK API.
-
-- trellis <integer>
-  - Enables trellis quantization.
-  - 0 means trellis is disabled.
-  - 1 means trellis is enabled for I-frames only.
-  - 2 means trellis is enabled for I and P-frames.
-  - 3 means trellis is enabled for all frames (I, P and B).
-  - Default: 0 (disabled)
-  - Note: ignored if the target-usage is too low (usually, only works in combination with tu=1).
-  - Caveats: requires hardware support (4th gen. Intel Core processor or equivalent), and driver support for version 1.7 of the Media SDK API.
-
-- lookahead (or la) <boolean>
-  - Use the !LookAhead (LA or LA_ICQ) bitrate control algorithm.
-  - Default: 1 (on)
-  - Caveats: requires hardware support (4th gen. Intel Core processor or equivalent), and driver support for version 1.7 (1.8 for LA_ICQ) of the Media SDK API.
-
-- lookahead-depth (or la-depth) <integer>
-  - If !LookAhead bitrate control is enabled, number of frames that are analyzed before encoding, from 11 to 60.
-  - Default: 40
-  - Note: may be sanitized to a lower value in some cases to avoid hangs.
-  - Caveats: requires hardware support (4th gen. Intel Core processor or equivalent), and driver support for version 1.7 of the Media SDK API.
-
-- force-cqp <boolean>
-  - In Constant Quality mode, use Constant QP rate control, even if Intelligent Constant Quality is available.
-  - Default: 0 (ICQ enabled if available)
-
-- cqp-offset-i <integer>   |  cqp-offset-p <integer>  |   cqp-offset-b <integer>
-  - In constant QP (CQP) bitrate control mode, specify offset from the global quality/QP value for I, P and B-frames.
-  - Defaults are 0, 2 and 4, respectively.
-
-- vbv-maxrate <integer>
-  - Sets the maximum rate the VBV buffer should be assumed to refill at, in kilobits per second (Kbps).
-  - Default: 0 (set at runtime by the implementation)
-  - Note: not compatible with Constant QP, Intelligent Constant Quality or !LookAhead rate control methods (ignored).
-
-- vbv-bufsize <integer>
-  - Sets the size of the VBV buffer in kilobits (Kb).
-  - Default: 0 (set at runtime by the implementation)
-  - Note: not compatible with Constant QP, Intelligent Constant Quality or !LookAhead rate control methods (ignored).
-
-- vbv-init <float>
-  - Sets how full the VBV Buffer must be before playback starts.
-  - If it is less than 1, then the initial fill is: vbv-init * vbv-bufsize.
-  - Otherwise it is interpreted as the initial fill in kilobits (Kb).
-  - Default: 0 (set at runtime by the implementation)
-  - Note: not compatible with Constant QP, Intelligent Constant Quality or !LookAhead rate control methods (ignored).

-AMD VCE Encoder
-==========================
+AMD VCE
+=======

-Supported Hardware and Configurations 
---------------
-- AMD Radeon RX 400 Series, Vega or better
-- Windows 10
+## Supported hardware 

-Please note, these are not hard limits and the feature *may* work on older cards and operating systems, but this is not officially supported.
+- AMD Radeon RX 400, 500, Vega/II, Navi series GPU or better
+- Ubuntu Linux 18.04.3 or later, Windows 10

-Enabling support
---------------
-Support for the VCE encoder can be enabled in preferences under the video tab. If your system is not supported, the option will be greyed out.
+Please note, these are not hard limits. Hardware encoding via VCE *might* work on older series GPUs and older operating systems, but this is not officially supported.

+On Ubuntu Linux, [AMD Radeon Software for Linux version 19.20 or later](https://www.amd.com/en/support/kb/release-notes/rn-amdgpu-unified-linux) is required to use the VCE encoder. Install using the `amdgpu-pro-install` script according to AMD’s [installation guide](https://amdgpu-install.readthedocs.io/en/latest/). Additionally, you must manually install the `amf-amdgpu-pro` package included in the download.

-Performance
---------------
-Take note that only the encode portion of the encode pipeline is done on the AMD hardware. 
-Every stage prior and after in the pipeline including (decoding, filters, a/v sync, muxing etc.) all happen on the CPU. As a result, it is normal to have high, or 100% CPU utilisation during encodes. 
+## Enabling support

-It is common, particularly on lower end hardware that the CPU may be a bottleneck for the encoder. To minimise this effect, turn off any filters that you do not require. 
+Support for the AMD VCE encoder is enabled in preferences on the video tab. If your system is not supported, the option will be disabled.

+## Performance

-Using the Advanced Options
---------------
-VCE does have a limited set of advanced encoder options that can be used.  Generally speaking is is not recommended to change these parameters. The built-in presets offer a good range of options.
+Only video encoding is performed by the hardware encoder. Every stage prior to and after video encoding including decoding, filters, audio/video sync, audio encoding, muxing, etc., is performed by the CPU. As a result, it is normal to have high (even 100%) CPU utilisation during encodes.
