No. VLC on macOS includes built‑in Xvid support. Install the system Xvid codec only if you also use other Mac media players.
Yes, the VLC mobile apps include the same FFmpeg decoding libraries as the desktop version, so they handle Xvid without any additional setup.
– Some older DVD/divx players require system codecs to be present.
VLC includes Xvid encoding capabilities via its Convert/Save interface. Choose the “Video – MPEG‑4 + MP3 (AVI)” profile to encode to Xvid.

Xvid (originally stylized as “XviD”) is a video codec library that follows the standard. In essence, Xvid is not a video format in itself; rather, it is a tool for compressing video into the MPEG‑4 ASP format, which can then be stored in containers such as AVI, MKV, or MP4. The name “XviD” was chosen as a playful inversion of “DivX,” underscoring its origins as an open‑source alternative to the proprietary DivX codec.
Unlikely. VLC prides itself on playing anything . As long as the FFmpeg project maintains the Xvid decoder, VLC will include it. The risk is near-zero.
The video plays choppy, freezes momentarily, or displays “blocky” compression artifacts.
Apple computers do not support Xvid natively in QuickTime. You must use third-party software like VLC Media Player to play them. Yes, the VLC mobile apps include the same
You can play Xvid videos immediately after installing VLC.
If your Xvid video came from an interlaced DVD source (common in TV recordings or home videos), you may see horizontal comb‑like artefacts. Enable deinterlacing:
In the early 2010s, users had to download dangerous "codec packs" (like K-Lite) to watch Xvid files. These often came with adware or broken system files. With VLC, you never install system-wide codecs. VLC handles Xvid internally, keeping your OS clean and stable.
– For large AVI files (especially over 2 GB), increasing the file cache can help. Go to Tools → Preferences → Show settings: All → Input/Codecs → Advanced → File caching (ms) . Try values between 1000 and 5000 ms. Choose the “Video – MPEG‑4 + MP3 (AVI)”
It eliminates the risk of downloading malicious external codec installers.
For the vast majority of users, . If VLC is installed on your computer, you can simply open an .avi or .mkv file containing Xvid video, and VLC will decode it instantly—no extra downloads, no registry edits, no system‑wide codec packs.
Despite being outdated, Xvid has a few niche advantages:
– If you also use Windows Media Player, Media Player Classic, or other players that rely on the Windows DirectShow codec chain, they won’t have access to VLC’s internal decoder. Installing Xvid system‑wide allows those players to play Xvid files too.
