Supports: MPG, MPEG
An MPEG file (.mpeg) is an MPEG program stream carrying MPEG-1 or MPEG-2 video — broad playback support but a dated, space-hungry codec. Converting to DivX re-encodes the video into the MPEG-4 Part 2 Advanced Simple Profile codec that DivX-certified DVD players and set-top boxes are built to decode, paired with MP3 audio in an AVI-style container. It is the right target when you have a specific DivX-logo player to feed; for phones, smart TVs, and the web, MPEG to MP4 (H.264) is the better choice.
| Property | MPEG (.mpeg) | DivX |
|---|---|---|
| Standard | ISO/IEC MPEG-1 (1993) / MPEG-2 (1995) | MPEG-4 Part 2 ASP; DivX codec released Jan 2001 |
| Video codec | MPEG-1 or MPEG-2 video | DivX (MPEG-4 ASP) |
| Audio (XConvert output) | MP2 in source | MP3 |
| Container | MPEG program stream | AVI-style (.divx) |
| Compression efficiency | Lower — larger files | Higher — more video per disc |
| Best for | Video CD / DVD-Video legacy, broad PC playback | DivX-certified DVD players, data-DVD movie discs |
No — re-encoding cannot recover detail. The MPEG source is already lossy, so the DivX output inherits whatever resolution and sharpness the original captured. What you gain is compatibility with DivX-certified hardware and smaller files at the same perceived quality, because MPEG-4 ASP compresses more efficiently than MPEG-1 and MPEG-2. Use the highest Quality Preset that still meets your size target, and prefer Variable Bitrate over Constant Bitrate for most content.
Effectively yes. DivX video is normally carried in an AVI-derived container, so the output is a DivX-codec AVI written with a .divx extension. Certified players read the DivX/Xvid FourCC tag inside the file, so it plays the same whether the extension is .divx or .avi. If a particular player is fussy about the extension, renaming to .avi after download is harmless.
A DivX logo means the player's decoder was tested against the DivX flavor of MPEG-4 — it does not guarantee MPEG-1 or MPEG-2 playback. An MPEG program stream uses a different codec family, so a DivX-only player may reject it or show video with no sound. Re-encoding to a DivX-codec file with MP3 audio at 720×576 or below gives the player exactly what its certification covers.
In our testing, a 4-minute standard-definition MPEG clip (roughly 70 MB at MPEG's typical bitrate) re-encoded to DivX at the default Very High preset produced about a 35-45 MB file, since MPEG-4 ASP is more efficient than the source codec at the same perceived quality. Choosing Specific file size lets you target an exact result — useful for fitting several clips on one 4.7 GB data DVD.
DivX makes sense only if you have a specific DivX-certified player you cannot replace — a mid-2000s DVD player, a portable media box, a kiosk. For anything modern, MPEG to MP4 with H.264 is the better pick: it plays on virtually every phone, TV, and browser and compresses better than DivX. If you specifically need a plain AVI container rather than the DivX flavor, see MPEG to AVI.
