About MPEG-4 Format MPEG-4 is a method of defining compression of audio and visual digital data, it is one of the latest compression method standardized by MPEG group, designed especially for low-bandwidth video/audio encoding purposes. DivX and XviD are fully standard-compliant MPEG-4 encoders nowadays. MPEG-4 is commonly used to store media types defined by the ISO/IEC Moving Picture Experts Group, though it can store other media types as well. The files of this format usually have extension .mp4. Unlike MPEG-1…

About MPEG Format MPEG stands for Moving Pictures Experts Groups, part of the International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC), to set standards for audio and video compression and transmission. The term also refers to the family of digital video compression standards and file formats developed by the group. MPEG generally produces better-quality video than competing formats, such as Video for Windows, Indeo and QuickTime. MPEG files previously on PCs needed hardware decoders (codecs) for MPEG processing.…

About MP4 Format When referring to the widely-used MP4 format, MPEG-4 should be mentioned. MPEG-4 is a standard that still be developing, and it’s divided into a number of parts. It is a compressed multimedia container format that can hold both video and audio file with a smaller file size without too much loss in quality. MPEG-4 can make distinctions among different objects in the video (such as people and background) intelligently, then isolated them and compressed one by one.…

About MP3 Format MP3, which is an acronym for MPEG-1 Audio Layer 3, is an audio encoding format. It is one of the most popular audio compression and decompression (codec) format today because of its ability to put music into manageable files, thus making downloading over the internet easy. Because MP3 files are small, they can easily be transferred across the Internet. As the name "MPEG-1 Audio Layer 3" implies, MP3 uses Layer 3 (one of three MPEG-1 coding schemes)…

About MOV Format MOV, also called QuickTime, is a multimedia container file format created by Apple Inc. It is primarily used with the company's QuickTime media player and is widely used for iTunes. A MOV file, with file extension ".mov", can contain video, graphics, animation, 3D and VR (virtual reality) content, or text (for example for subtitles). It acts as a multimedia container for digital videos, and its multitracking ability allows editors to shape the file in a variety of…

About MKV Format The MKV extension is Matroska Multimedia Container which is an open standard free container format. As the name implies (the Russian egg-shaped dolls contained within one another) Matroska can contain video (DivX, Xvid, RV9, etc), sound (MP3, MP2, OGG, AC3, AAC, DTS, PCM), as well as subtitles (SRT, ASS, SSA, USF, etc) in the same file. So it allows a complete movie to be stored in a single file. If the container holds only audio files, MKA…

About M4V Format M4V is a file container format used by Apple's iTunes application. The M4V file format is a video file format developed by Apple and is very close to MP4 format. The differences are the optional Apple's DRM copyright protection, and the treatment of AC3 (Dolby Digital) audio which is not standardized for the MP4 container. In addition, M4V files are opened with iTunes player by default. MP4 files are opened with QuickTime player by default. M4V files…

About M4A Format 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. The M4A file type is primarily associated with 'MPEG-4 Audio Layer'. Files in .M4A format are actually the audio layer of…

About MTS / M2TS Format MTS is a high definition video file format. It's commonly used for high definition video on Blu-ray disc, AVCHD and HD camcorder. MTS file is a container file format and uses the .mts as file extension. It's based on the MPEG-2 transport stream container and is also known as BDAV MPEG-2 transport stream. MTS file usually takes AVC or H.264 or MPEG2 as its video encoding algorithm and AC-3 as its audio encoding algorithm. M2TS…
