Video File Formats 3GPP Multimedia File (3gp) | Is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for 3G UMTS multimedia services. It is used on 3G mobile phones but can also be played on some 2G and 4Gphones. | Advanced Systems Format File (asf) | File format that wraps various content bit streams; data types can include audio, video, script command, JPEG-compressed still images, binary, and other streams defined by developers. This description is focused on the use of the format for audio and video. | Audio Video Interleave File (avi) | Is a multimedia container format that can contain both audio and video data in a file container that allows synchronous audio-with-video playback. Like the DVD video format, AVI files support multiple streaming audio and video, although these features are seldom used. | Flash Video File (flv) | Is container file format used to deliver video over the internet using Adobe Flash Player version 6-11. | iTunes Video File (m4v) | Is a video format and file extension extremely resembling traditional and common MP4 (MPEG-4 Video File). M4V video file format is developed by Apple Inc., who uses it to flag as a video file and attach it to iTunes, by encoding TV episodes, movies, and music videos in the iTunes Store under official DRM copy protection. | Apple QuickTime Movie (mov) | Is a common multimedia format often used for saving movies and other video files, using a proprietary compression algorithm developed by Apple Computer, compatible with both Macintosh and Windows platforms. | MPEG-4 Video File (mp4) | Is a container format allowing a combination of audio, video, subtitles and still images to be held in the one single file. It also allows for advanced content such as 3D graphics, menus and user interactivity. | MPEG Video File (mpg) | Is a standard for lossy compression of video and audio. It is designed to compress VHS-quality raw digital video and CD audio down to 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively)[1] without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) possible. | SubRip Subtitle File (srt) | Is a software program for Windows which "rips" (extracts) subtitles and their timings from video. It is free software, released under the GNU GPL. SubRip is also the name of the widely used and broadly compatible subtitle text file format created by this software. | Shockwave Flash Movie (swf) | Can contain video and vector based animations and sound and are designed for efficient delivery over the web. SWF files can be viewed in a web browser using the Flash plug in. | Windows Media Video File (wmv) | Is a compressed video compression format for several proprietary codecs developed by Microsoft. The original video format, known as WMV, was originally designed for Internet streaming applications. |

Audio File Formats Audio Interchange File Format (aif) | Is an audio file format standard used for storing sound data for personal computers and other electronic audio devices. | Media Playlist File (m3u) | Is a computer file format that stores multimedia playlists. It is supported by many applications, including media players such as Windows Media Player, iTunes, Winamp, Audacious, foobar2000, Totem, JuK and VLC media player on Windows PC's and Astro Player, N7Player, Cubed on Android OS devices. M3U's can also point a media player to an online streaming audio source. | MPEG-4 Audio File (m4a) | Is a file extension for an audio file encoded with advanced audio coding (AAC) which is a lossy compression. M4A was generally intended as the successor to MP3, which had not been originally designed for audio only but was layer III in an MPEG 1 or 2 video files. M4A stands for MPEG 4 Audio. | MIDI File (mid) | Is a technical standard that describes a protocol, digital interface and connectors and allows a wide variety of electronic musical instruments, computers and other related devices to connect and communicate with one another. | MP3 Audio File (mp3) | Is an encoding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players. | WAVE Audio File (wav) | Is a Microsoft and IBM audio file format standard for storing an audio bit stream on PCs. It is an application of the Resource Interchange File Format (RIFF) bit stream format method for storing data in "chunks", and thus is also close to the 8SVX and the AIFF format used on Amiga and Macintosh computers, respectively. It is the main format used on Windows systems for raw and typically uncompressed audio. | Windows Media Audio File (wma) | Is an audio data compression technology developed by Microsoft. The name can be used to refer to its audio file format or its audio codecs. It is a proprietary technology that forms part of the Windows Media framework. |

Graphics File Formats Bitmap Image File (bmp) | Is a raster graphics image file format that stores color data for each pixel in the image without any compression. | DirectDraw Surface (dds) | Is a standard for storing data compressed with the lossy S3 Texture Compression algorithm, which can be decompressed in hardware by graphical textures and cubic environment maps as a data file, both compressed and uncompressed. | Graphical Interchange Format File (gif) | It supports up to 8 bits per pixel for each image, allowing a single image to reference its own palette of up to 256 different colors chosen from the 24-bit RGB color space. It also supports animations and allows a separate palette of up to 256 colors for each frame. | JPEG Image (jpg) | Is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. | Portable Network Graphic (png) | Is a raster graphics file format that supports lossless data compression. It supports palette-based images (with palettes of 24-bit RGB or 32-bitRGBA colors), grayscale images (with or without alpha channel), and full-color non-palette-based RGB[A] images (with or without alpha channel). | Adobe Photoshop Document (psd) | It stores an image with support for most imaging options available in Photoshop. These include layers with masks, transparency, text, alpha channels and spot colors, clipping paths, and duotone settings. | Targa Graphic (tga) | It was the native format of TARGA and VISTA boards, which were the first graphic cards for IBM-compatible PCs to support High color/true color display. | Thumbnail Image File (thm) | Is an image file format for thumbnails that are usually used in the internet for clip art and image galleries that are contained on the user’s hard drive or camera. | Tagged Image File Format (tiff) | Is a computer file format for storing raster graphics images and it is widely supported by image-manipulation applications, by publishing and page layout applications, and by scanning, faxing, word processing, optical character recognition and other applications. | YUV Encoded Image File (yuv) | Is a color space typically used as part of a color image pipeline. It encodes a color image or video taking human perception into account, allowing reduced bandwidth for chrominance components, thereby typically enabling transmission errors or compression artifacts to be more efficiently masked by the human perception than using a "direct" RGB-representation. |
