HandBrake

HandBrake is a tool for converting video from nearly any format to a selection of modern, widely supported codecs.

Reasons you’ll love HandBrake:

• Convert video from nearly any format
• Free and Open Source
• Multi-Platform (Windows, Mac and Linux)

HandBrake是一种转码工具，它可以处理几乎所有的视频格式。
免费开源并且跨平台。

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利用已有的视频生成新视频，这些视频可在手机、平板、电视播放器、游戏终端、电脑或网络浏览器中播放。

Source formats

One of HandBrake’s strengths is its ability to open a wide variety of video formats. HandBrake uses Libav under the hood and generally can open whatever Libav will, in addition to disc-based formats like DVD and Blu-ray.

HandBrake的厉害之处就在于可处理大量的视频格式。
HandBrake使用了Libav库，可处理Libav可处理的所有文件，另外DVD和蓝光这种disc-based的格式也能处理。
从来源角度进行分类，HandBrake可处理的视频的来源主要有:

1. Videos made by mobile phones, tablets, and many video cameras and DSLRs

Typically, each video will be a single file that you can copy to your computer, and later open using HandBrake. Common video file types are MP4 or M4V, MOV, MPG or MPEG, and AVI.

通常情况下，每个视频可作为一个独立的文件拷贝至电脑，然后用HandBrake打开。

Some cameras store multiple videos in a folder structure with a playlist similar to Blu-ray discs, specifically cameras that record in AVCHD or AVCHD Lite. HandBrake may be able to open individual video files from the Stream folder inside the BDMV folder. In some cases this is not reliable, e.g. where a single video stream spans multiple files.

有些录像机，尤其用AVCHD or AVCHD Lite录制的摄像机，存储内容如下:

• 在文件夹下多个视频文件
• 一个和蓝光光碟中类似的playlist

HandBrake也许能够打开BDMV目录下流目录中的单个视频文件。但是，如果一个视频文件被span为多个文件，HandBrake会无法打开。

Handbrake可处理“移动手机、平板、视频摄像机及数码单反相机录制的视频”。

• video cameras and DSLRs

数码单镜反光相机（Digital Single Lens Reflex Camera，常简称为DSLR），简称数码单反相机是一种以数码方式记录成像的照相机。属于数码静态相机（Digital Still Camera, DSC）与单反相机（SLR）的交集。

2. Screen and game recordings, web videos, video editing projects, and other computer-related sources

Handbrake还可以处理来自于屏幕录制、游戏录屏、网络上的视频等。

Some screen recording softwares can export or record directly to video files HandBrake can open. Common video file types are MP4 or M4V, MKV, MPG or MPEG, AVI, and WMV.

某些录屏软件可以直接导出或直接录制成Handbrake可打开的视频文件。常见的视频格式有MP4 or M4V, MKV, MPG or MPEG, AVI, and WMV.

HandBrake can open web videos in FLV, WEBM, MP4, and many other formats.

HandBrake可打开如下格式的网络视频: FLV, WEBM, MP4和其它格式。

Videos made using consumer video editing software such as iMovie must first be exported to a common video format for compatibility with HandBrake.

iMovie进行编辑处理的视频，必须事先导出为一个通用的视频格式，这样才能和HandBrake兼容。

3. Professional video production formats

HandBrake can open a number of production formats produced by professional video cameras and NLEs(Non-linear editing system), including ProRes and DNxHD.

HandBrake可以处理以下来源的输出视频:

• 专业的视频摄像机
• 非编软件(比如ProRes和DNxHD)

4. DVD, Blu-ray, AVCHD/AVCHD Lite¹, and HD-DVD² discs or disc backups

HandBrake can directly open DVD and Blu-ray discs. In most situations it is better to first copy the contents to your computer’s hard drive³. Common folders are VIDEO_TS and BDMV. Common video file types are VOB, EVO, and MTS or M2TS.

HandBrake可直接打开DVD(Digital Video Disc)和蓝光光碟。
大多数情况下，最好将光碟中的内容先拷贝到电脑硬盘上。
常见的目录一般有VIDEO_TS和DBMV。
常见的视频文件格式有VOB, EVO, and MTS or M2TS.

Certain third-party disc copy tools such as MakeMKV commonly make… wait for it… MKV video files. Other tools create ISO (sometimes labeled CDR) images of DVD and Blu-ray discs. HandBrake usually can open these directly.

某些第三方光碟拷贝工具比如MakeMKV可以生成MKV视频文件。
有些其它工具可生成DVD和蓝光光碟的ISO镜像。
HandBrake可直接处理以上格式。

BIN+CUE, MDF+MDS, and Toast images must first be mounted. Open the image using your operating system or appropriate software, and then open the virtual disc with HandBrake.

对于BIN+CUE, MDF+MDS, and Toast images，需要首先挂在以上格式；然后用操作系统或合适的软件打开镜像，最后用HandBrake打开虚拟的光碟。

5. Broadcast TV recordings

HandBrake can open common video file types produced by TV recording hardware and software such as TS/MTS/M2TS, MP4 or M4V, and MPG or MPEG.

HandBrake可打开TV录制软件生成的大多数视频格式。
比如TS/MTS/M2TS, MP4 or M4V, and MPG or MPEG。

Recordings made by TV-to-DVD recorders are generally supported, but do note that some recorders are known for poorly making discs. Some discs may not work due to mastering errors.

基本支持TV-to-DVD录制的内容。
但需要注意，有些录制机生成disc的能力不强，所以可能导致HandBrake无法处理某些discs。

6. Digital recordings of VHS, Beta, Video8/Hi8, LaserDisc, and other analog sources

First convert your analog video to digital using a computer-based hardware recording device such as the Blackmagic Design Intensity. It is important to choose a recording device and software that allows recording to or exporting to common video formats. HandBrake can open many common video files produced by recording software, including but not limited to TS/MTS/M2TS, MP4 or M4V, MOV, MKV, MPG or MPEG, and AVI.

处理前，需要先用硬件录制设备(比如Blackmagic Design Intensity)将模拟视频转换为数字视频。
选择合适的录制设备和软件(用来录制或导出通用视频格式)，是非常重要的。
HandBrake可处理录制软件输出的很多通用格式的视频，比如TS/MTS/M2TS, MP4 or M4V, MOV, MKV, MPG or MPEG, and AVI等等。

1. AVCHD and AVCHD Lite playlists are not fully supported. Individual files/streams may work.

HandBrake无法全部支持AVCHD and AVCHD Lite的playlists。
但可能支持对单独的文件或流的处理。

2. HD-DVD playlists are not fully supported. Individual files/streams may work.

HandBrake无法全部支持HD-DVD 的playlists。
但可能支持对单独的文件或流的处理。

3. Without special software, it is not possible to directly copy VIDEO_TS and BDMV folders from copy-protected discs.

必须用特殊的软件，才能从版权保护的discs中直接拷贝出VIDEO_TS和BDMV目录。
