Xvid vs MP4 — Open-Source DivX Alternative vs Modern Container

Xvid is an open-source video codec implementing MPEG-4 Part 2 (Advanced Simple Profile), the same standard DivX uses. Xvid was the open-source alternative dominant in P2P video sharing of the 2000s. MP4 with H.264 became the modern successor — better efficiency, broader device support.

Quick Verdict

Use Xvid when…

Xvid is legacy. Keep Xvid files only for archive or compatibility with old hardware.

Use MP4 when…

Use MP4 (H.264) for any new video work. Better compression, universal compatibility, and the only sensible target format for current devices.

Frequently asked questions

Are Xvid and DivX the same?

Both implement the same MPEG-4 Part 2 (ASP) standard. Xvid is open-source and free; DivX is commercial. Both produce broadly compatible video. Decoding either requires the same generation of decoder hardware/software.

Can I play Xvid on an iPhone?

Not natively. iOS doesn't decode MPEG-4 Part 2 (Xvid/DivX) directly. VLC for iOS plays Xvid. For native iOS playback, convert to MP4 (H.264): `ffmpeg -i input.avi -c:v libx264 -c:a aac output.mp4`.
