Mpeg2 Vs Mpeg4 - Comparision.
What is MPEG2?
MPEG-2 coding format which was developed in 1995 was commonly applied to digital television broadcast, DVD, VCD and similar discs. It uses lossy compression techniques for audio and video files, to substantially reduce file sizes. What is MPEG4? MPEG-4 which was created in 1998 was mainly developed with the aim of achieving higher compression, lower bandwidth while providing superior audio and image quality compared to the earlier MPEG-2 format. In brief, its goal is to gain better picture and audio quality with smaller file size. It was specifically developed for mobile devices and online streaming or transmission. Most modern video codecs are based on MPEG4 like DivX and Xvid. Differences between MPEG2 and MPEG4 MPEG2 vs MPEG4 – Application MPEG2 is the encoding method used for television broadcast and DVDs, while MPEG4 coding standard is primarily applied to portable devices and Internet streaming. MPEG2 vs MPEG4 – Compression Video or audio compression is all about maintaining the same audio or video quality in lesser number of bits. In this respect, MPEG4 is much more compressed than MPEG2 because of the superior compression algorithm used. MPEG2 vs MPEG4 - File Size MPEG4 encodes video files with much smaller size as it can produce a full-length movie file less than 1G while MPEG2 can only yield movie files with 5 times the size. You can store MPEG2 files on DVDs for many DVD capacity is larger than 4 GB, but it is not applicable to portable devices. On the other hand, MPEG4 is smaller and makes it possible to buy and download videos online. MPEG2 vs MPEG4 – Quality MPEG2 produces flawless quality compared to MPEG4 but it is not made for multimedia applications or online streaming. Its large size makes it impractical for network streaming. While MPEG4 provides better video audio quality when streamed online. MPEG2 vs MPEG4 – Bit Rate & Bandwidth MPEG4 is aimed at low bit-rate video transmission. Files encoded in MPEG4 format have a much lower bit rate ranging from a few kilobytes per second to megabytes per second while MPEG2 is tens megabytes per second. MPEG2 requires much more bandwidth when streaming recorded or real-time videos online compared to MPEG4 because of its large size. |
