Supports: MPEG2
MPEG-2 is the DVD- and broadcast-era video codec (ISO/IEC 13818 / ITU-T H.262, standardized in 1996), and Xvid is an open-source MPEG-4 Part 2 (Advanced Simple Profile) codec usually carried in an AVI container. Re-encoding MPEG-2 to Xvid is a transcode between two older codecs: the practical payoff is a noticeably smaller file at similar quality, plus playback on Xvid- and DivX-certified standalone DVD and media players. If your goal is just a modern, universal, small file, MP4 (H.264) compresses harder and plays almost everywhere — pick Xvid only when you specifically need a DivX/Xvid-era device or an AVI workflow.
| Property | MPEG-2 | Xvid | MP4 (H.264) |
|---|---|---|---|
| Codec family | MPEG-2 Part 2 / H.262 | MPEG-4 Part 2 ASP | MPEG-4 Part 10 AVC |
| Standardized | 1996 (ISO/IEC 13818) | MPEG-4 ASP, 1999; Xvid encoder 2001 | 2003 (ISO/IEC 14496-10) |
| Typical container | .mpg / .mpeg / .m2v / VOB | .avi (also .divx) | .mp4 / .mov |
| Compression efficiency | Lowest of the three | ~2x better than MPEG-2 | Best of the three |
| Open / licensed | Patented; patents now expired | Open-source (GPL) | Patented (royalty pools) |
| Best for | DVD video, legacy broadcast | DivX/Xvid standalone players, AVI archives | Web, phones, modern TVs |
They are close cousins, not identical. Both implement the MPEG-4 Part 2 Advanced Simple Profile (ASP) standard. Xvid began in 2001 as an open-source fork of OpenDivX after DivX, Inc. closed its source, so the two share the same encoding lineage and produce interchangeable AVI files in practice. The difference is licensing: Xvid is free and GPL-licensed, while the DivX codec is a proprietary product.
Usually yes. DivX Home Theater certified devices are designed to play standard-definition AVI/DIVX MPEG-4 ASP content, and because Xvid uses the same ASP profile, those players generally read Xvid AVIs as well. Compatibility is best at standard resolutions and conservative bitrates; very high bitrates or unusual GMC/Qpel options can trip up older hardware, so the default preset is the safest choice.
Any re-encode between two lossy codecs discards some data, but at the "Very High" preset the loss is hard to see at normal viewing distances. You generally end up with a smaller file at comparable visible quality because MPEG-4 ASP compresses more efficiently than MPEG-2. Re-encoding cannot add detail, though — a standard-definition MPEG-2 source stays standard-definition.
MPEG-4 Part 2 ASP (Xvid) is a more efficient codec than MPEG-2, so it represents the same picture with fewer bits — commonly around half the size at similar quality. You can shrink it further with the File Compression options by targeting a specific file size or a lower bitrate.
If you do not need a legacy DivX/Xvid device, yes. H.264 in MP4 compresses harder than Xvid and plays natively on phones, browsers, and modern TVs. Use MPEG-2 to MP4 for that path, or Xvid to MP4 if you already have Xvid files to modernize. Choose Xvid only when the destination hardware specifically expects it.
Yes. Add multiple .mpg or .mpeg files and they convert with the same Quality Preset and resolution settings. For large source files the main wait is the upload — MPEG-2 DVDs can run several gigabytes — so a faster connection speeds things up more than anything on the settings panel.
