Free MP4 Converter is professional MP4 Video Converting software, which helps you convert any video format to and from MP4 video for playback on iPhone (iPhone X/8/7/SE/6s/6s Plus/6/6 Plus/5s/5c/5/4S), iPad (iPad Pro/Air 2/mini 3/4/Air/mini 2), iPod, and Apple TV. It also supports converting video t.
Although Mac's default player supports the MP4 video format natively, it can only play files compressed with MPEG-4, MPEG-2, and H.264 codecs. If you want to play an MP4 file encoded with a different codec, you'll need to install a player that supports that codec, or simply convert the file to the MOV format. Since QuickTime Player is the default player for all Mac desktop and notebook types, be it iMac, Mac Mini, MacBook or Mac Pro, the video formats supported by QuickTime will also be compatible with Mac computer running OS X v10.6.x or later, or even the latest macOS Catalina. With Mac OS X installed, you are tethered to do everything on Mac. In consideration that you might run into Mac video formats incompatibility issues while watching videos, this guide focuses on the best audio and video format for Mac OS X, so that you can have a hassle-free video enjoyment whether you are using Mac Pro, MacBook, iMac or Mac Mini.
A video file format is a type of file format for storing digital video data on a computer system. Video is almost always stored using lossy compression to reduce the file size.
A video file normally consists of a container (e.g. in the Matroska format) containing video data in a video coding format (e.g. VP9) alongside audio data in an audio coding format (e.g. Opus). The container can also contain synchronization information, subtitles, and metadata such as title. A standardized (or in some cases de facto standard) video file type such as .webm is a profile specified by a restriction on which container format and which video and audio compression formats are allowed.
The coded video and audio inside a video file container (i.e. not headers, footers, and metadata) is called the essence. A program (or hardware) which can decode compressed video or audio is called a codec; playing or encoding a video file will sometimes require the user to install a codec library corresponding to the type of video and audio coding used in the file.

Good design normally dictates that a file extension enables the user to derive which program will open the file from the file extension. That is the case with some video file formats, such as WebM (.webm), Windows Media Video (.wmv), Flash Video (.flv), and Ogg Video (.ogv), each of which can only contain a few well-defined subtypes of video and audio coding formats, making it relatively easy to know which codec will play the file. In contrast to that, some very general-purpose container types like AVI (.avi) and QuickTime (.mov) can contain video and audio in almost any format, and have file extensions named after the container type, making it very hard for the end user to use the file extension to derive which codec or program to use to play the files.
The free softwareFFmpeg project's libraries have very wide support for encoding and decoding video file formats. For example, Google uses ffmpeg to support a wide range of upload video formats for YouTube.[1] One widely used media player using the ffmpeg libraries is the free software VLC media player, which can play most video files that end users will encounter.
List of video file formats[edit]
| Name | File extension(s) | Container format | Video coding format(s) | Audio coding format(s) | Notes |
|---|---|---|---|---|---|
| WebM | .webm | Matroska | VP8, VP9, AV1 | Vorbis, Opus | Royalty-free format created for HTML5 video. |
| Matroska | .mkv | Matroska | any | any | |
| Flash Video (FLV) | .flv | FLV | VP6, Sorenson Spark, Screen video, Screen video 2, H.264 | MP3, ADPCM, Nellymoser, Speex, AAC | Use of the H.264 and AAC compression formats in the FLV file format has some limitations and authors of Flash Player strongly encourage everyone to embrace the new standard F4V file format[2] de facto standard for web-based streaming video (over RTMP). |
| F4V | .flv | MPEG-4 Part 12 | H.264 | MP3, AAC | Replacement for FLV. |
| Vob | .vob | VOB | H.262/MPEG-2 Part 2 or MPEG-1 Part 2 | PCM, DTS, MPEG-1, Audio Layer II (MP2), or Dolby Digital (AC-3) | Files in VOB format have .vob filename extension and are typically stored in the VIDEO_TS folder at the root of a DVD. The VOB format is based on the MPEG program stream format. |
| Ogg Video | .ogv, .ogg | Ogg | Theora, Dirac | Vorbis, FLAC | |

| GIF | .gif | N/A | N/A | none | Simple animation, inefficient compression, no sound, widely supported |
| Video alternative to GIF | .gifv | HTML | any | none | Not standardized, and not a real video file in the classical meaning since it merely references the real video file (e.g. a .webm file), which has to exist separately elsewhere. A .gifv 'file' is simply a HTML webpage which includes a HTML5 video tag, where the video has no sound. As there were large communities online which create art using the medium of short soundless videos in GIF format, GIFV was created as a functionally similar replacement with vastly smaller filesizes than the inefficient GIF format. |
