![]() ![]() XviD, an open-source version of DivX, popular among movie pirates. Most of the DivX videos use avi file extension, of course, DivX and Div extension. Now, this compression algorithm of the MPEG is used by many encoding formats, such as ASF, DivX, Xvid, mp4 (Apple, mpeg-4 encoding format) are using the MPEG-4 compression algorithm.ĭivX video encoding technology can be said produced for DVD, which works with a certain type of MPEG-4 file, and was often used to rip DVDs in the pre-HD era. MPEG-4 is a new compression algorithm, the use of this compression algorithm can be a 120-minute film (the original video files) is compressed to about 300MB. Use this compressed file format made by the algorithm is generally the VOB file. Using the MPEG-2 compression algorithm could produce a 120-minute film (the original video files) in the size of about 4GB to 8GB, of course, image quality indicators are MPEG-1 can not be compared. MPEG-2, its compression algorithm used in the production of the DVD (* vob - file formats), and also in some of the HDTV (high definition television) and high demand video editing, processing of the application. ![]() Using the MPEG-1 compression algorithm, a 120-minute film (the original video files) can be compressed to about the size of 1.2 GB, and the file format is generally mpg and dat files. Almost all VCD is compressed using the Mpeg-1 format (*. MPEG-1, its compression algorithm is widely used in the production of VCD and the download of some video clips. MPEG format, including MPEG video, MPEG audio, and MPEG (video, audio synchronization) of three parts, MP3 (MPEG-3) audio files is a typical application of the MPEG audio, the video includes MPEG-1, MPEG-2, and MPEG4. MPEG (Motion Picture Experts Group) is one of the biggest families in video codec, and it is the most common video format. For the same reason, you also might be able to play the audio portion of an AVI file, but not the video portion.Ĭonsequently, sometimes the player supports the video format but still cannot play the video, why? It’s because the video is with an incompatible video codec. Consequently, you might be able to play some AVI files and not others, depending on which codecs were used to compress the file and which codecs you have installed on your computer. AVI files can also contain data that is not compressed by any codec. However, a file format such as Audio Video Interleaved (AVI) can contain data that is compressed by any of a number of different codecs, including the MPEG-2, DivX, or XviD codecs. And sometimes they have the same name.įor example, a file format such as Windows Media Audio contains data that is compressed by using the Windows Media Audio codec. And for a container that can obtain a different encoding format video and audio. ![]() Inside the container is data that has been compressed by using a particular codec. What is the Difference between Video Codec and File Formats?Ī file format is like a type of container. When you play that WMA file (or any WMA file that might be streamed from a website), the Player uses the Windows Media Audio codec to decompress the file so the music can be played through your speakers. Some codecs include both of these components and some codecs only include one of them.įor example, when you rip a song from an audio CD to your computer, the Player uses the Windows Media Audio codec by default to compress the song into a compact WMA file. The encoder performs the compression (encoding) function and the decoder performs the decompression (decoding) function. The "codec" can be dividing into 2 parts: encode and decode. A codec is a device or software that is used to compress or decompress a digital media file, such as a video or song. ![]()
