Finally, play the resulting WebM/VP9 file in major browsers or players like VLC (2.1.3+) and MPC-HC (1.7.1+).\n"],null,["Getting Started with VP9\n------------------------\n\n### Introduction\n\nTo try encoding with VP9 video, you will need:\n\n1. a sample video\n2. a way of encoding the video to VP9 so you can experiment with settings\n3. a way of playing the VP9 to see the quality impact of those settings\n\n### Step 1: Get Sample Video\n\nThe [Tears of Steel](https://mango.blender.org/) short movie covers a range of test cases\nincluding action sequences and animation.\n\nTo test low-bitrate encoding profiles (for web and mobile), we use the\n[WebM 1080p version](http://media.xiph.org/mango/tears_of_steel_1080p.webm) of the clip. This file is encoded using VP8\nvideo, compressed at about 6Mbps -- a suitable starting point for web and\nmobile compression testing.\n\nFor higher bit-rate encoding, you may wish to download the\n[4K version](http://ftp.nluug.nl/pub/graphics/blender/demo/movies/ToS/) of the same movie.\n\n### Step 2: Encode VP9\n\nA [variety](http://www.webmproject.org/tools/) of encoding products and cloud service providers\nallow you to encode VP9 video.\n\nThese pages assume you are using [FFmpeg](https://ffmpeg.org/). You can [download](https://ffmpeg.org/download.html) a\npre-compiled version of FFmpeg, or [compile](https://trac.ffmpeg.org/wiki/CompilationGuide) FFmpeg with the\n`--enable-libvpx` option on your system.\n| **Note:** FFmpeg must be compiled with the `--enable-libvpx` option for VP9 to work. Most pre-compiled versions include this option by default. If your version of FFmpeg does not create VP9, it may be missing this compilation option.\n\nFFmpeg is a command-line program. Once you have it installed, you can perform\nencodes from the command line.\n\nAn easy example to get started, using the Tears of Steel clip above, is: \n\n ffmpeg -i tears_of_steel_1080p.webm -c:v libvpx-vp9 -c:a libopus output.webm\n\nThis command tells FFmpeg to:\n\n- Use *tears_of_steel_1080p.webm* as input (`-i tears_of_steel_1080p.webm`)\n- Set the output video codec to VP9 (`-c:v libvpx-vp9`)\n- Set the output audio codec to Opus (`-c:a libopus`)\n- Create a WebM output file named `output.webm`\n\n### Step 3: Play the video\n\nYou can play WebM/VP9 in [most major browsers](http://caniuse.com/#feat=webm), including Firefox,\nOpera, Chrome and Microsoft Edge. In Chrome, you can drag the file into the\nbrowser and it will play in that tab.\n\nOther players also support VP9/WebM decoding, including:\n\n| Player | Platform | Version |\n|--------|----------------|------------------------------------------------------------------|\n| VLC | Most Platforms | [Version 2.1.3 or later](https://www.videolan.org/vlc/#download) |\n| MPC-HC | Windows | [Version 1.7.1 or later](https://mpc-hc.org/downloads/) |"]]
