First, let's go through the terminology quickly. Formats like MP3, MP4 and WebM are called container formats. They define a structure in which the audio and/or video tracks that make up the media are stored, along with metadata describing the media, what codecs are used to encode its channels, and so forth.

A WebM file containing a movie which has a main video track and one alternate angle track, plus audio for both English and Spanish, in addition to audio for an English commentary track can be conceptualized as shown in the diagram below. Also included are text tracks containing closed captions for the feature film, Spanish subtitles for the film, and English captions for the commentary.
The audio and video tracks within the container hold data in the appropriate format for the codec used to encode that media. Different formats are used for audio tracks versus video tracks. Each audio track is encoded using an audio codec, while video tracks are encoded using (as you probably have guessed) a video codec. As we talked about before, different browsers support different video and audio formats, and different container formats (like MP3, MP4, and WebM, which in turn can contain different types of video and audio).
There are some special cases. For example, for some types of audio, a codec's data is often stored without a container, or with a simplified container. One such instance is the FLAC codec, which is stored most commonly in FLAC files, which are just raw FLAC tracks.
FFmpeg is an open source package that is used to convert audio and video into a wide variety of formats. Both ImageMagick and MoviePy are dependent on FFmpeg and will typically download it is if needed. This should be installed along with ImageMagick. Note that FFmpeg will download required additional code and updates the first time that it is run in our blog post example code.
MoviePy is an open source Python module for video editing that can be used for basic operations (like cuts, concatenations, and title insertions), video compositing (non-linear editing), video processing, or to create advanced effects. It can read and write the most common video formats. Our example uses MoviePy for subtitling, audio processing (adding foreign language tracks), and compositing all of the pieces together into the final videos.
Thanks Edward! Windows 8.1 should not be an issue, at the time I had tested it on Ubuntu.The gTTS module underneath uses the translate.google.com website, see inside the gtts source code. This website returns an audio file, which is played with any sound player (mpg321 as example).

If you've downloaded one of the releases or installed via a package manager, you've probably noticed that the contents are slightly different from the source code available on Github. The former includes just the compiled files necessary to use Video.js, and the latter includes the source used to create those files.
4 Best Free Ways to Download Audio Tracks for MoviesWhere to download audio tracks for movies? This post offers 4 places to get free movie audio tracks and shows you how to extract an audio track from a movie.
If you have ever tried to watch movies or TV shows with multiple audio tracks using VLC, you have likely run into some troubles with having to choose the audio track with each episode. For example, your favorite Japanese anime may always play the Japanese audio track when you want it to play the English track. Luckily, setting the default language is a simple process.
MakeMKV is your one-click solution to convert video that you own into free and patents-unencumbered format that can be played everywhere. MakeMKV is a format converter, otherwise called "transcoder". It converts the video clips from proprietary (and usually encrypted) disc into a set of MKV files, preserving most information but not changing it in any way. The MKV format can store multiple video/audio tracks with all meta-information and preserve chapters. There are many players that can play MKV files nearly on all platforms, and there are tools to convert MKV files to many formats, including DVD and Blu-ray discs.Additionally MakeMKV can instantly stream decrypted video without intermediate conversion to wide range of players, so you may watch Blu-ray and DVD discs with your favorite player on your favorite OS or on your favorite device.
With some DVD sources, there is a subtitle track which only displays during foreign language sections of the video. On some titles this is a unique subtitle track in the same language as the main audio track, on others it uses the standard subtitle track in the same language as the main audio track except marks a subset of the subtitles as forced. 2ff7e9595c
