While the MPEG-1 codec allows for only progressive scanning, MPEG-2 also supports interlacing. MPEG-2 is the only video compression standard for DVD and some Blu-ray discs. MPEG-1 codec provides high-quality video and MP3 sound that can be played on all modern music devices. MPEG codecsĪmong the most recognized codecs, there are those based on MPEG (Moving Picture Experts Group) standards.
Now let’s examine the most popular video codecs. The 2nd ones get rid of all unnecessary data and also save space. The 1st type cuts up the original file and quantizes it into a more efficient space. Lossy codecs can be transformative, predictive, or a combination of both types. Although lossy codecs (Xvid, DivX, VP3, MPEG4) lose some amount of video information, videos with such codecs occupy less space than lossless ones. Videos encoded with lossless codec usually have great quality but take a lot of hard drive space. These codecs (H.264, Lagarith, Huffyuv) reproduce a video as-is, without any quality loss.

For example, an AVI file can contain video compressed by XviD, or DivX, or MPEG-2 codecs. Inside it, you can find data that has been compressed by using a particular codec. However, there are rare codecs from special video cameras that can be viewed with VLC or a similar player with a proper codec library.Ī video codec isn’t the same as a video format or container. A container is a bundle of files. Of course, a majority of videos are encoded with the help of most popular codecs mentioned above and can be played with almost any multimedia player. In fact, there is a huge list of codecs that you can find online. A video codec is usually identified by ‘fourcc’, a four character code.
It converts uncompressed video to a compressed format to take up less space on your computer and vice versa. In other words, a codec processes raw digital video and stores it in a stream of bytes.
