No affiliate links or sponsorship. BravoTech isn’t affiliated with Xvid or VideoLAN. This codec explainer is based on xvid.com, labs.xvid.com, and videolan.org, checked October 16, 2026. We did not encode, play, or convert sample files for this rewrite. More software and tool reviews.
Quick answer
Xvid is a free, open-source video codec (MPEG-4 Part 2 / ASP), not a file format—Xvid video usually sits inside an .avi file. It is lossy (Xvid calls it an “MP3 for video”), and the last release is 1.3.7 from December 28, 2019. In 2026 the simplest way to play those files is VLC, which lists MPEG-4 ASP / XviD among supported formats and needs no separate codec pack.
Key takeaways
- Codec, not container: AVI, MKV, and MP4 are containers; Xvid is the compression inside (most often AVI).
- Lossy: Xvid’s own site says it removes detail like MP3 does for audio—do not call it lossless.
- Last release: Xvid 1.3.7 on December 28, 2019 (labs.xvid.com).
- Play with VLC: free on Windows, Mac, Linux, iOS, and Android; VideoLAN lists MPEG-4 ASP, XviD.
- Skip random codec packs: get software only from xvid.com or use VLC’s built-in decoders.
How we wrote this guide
Refresh of the live BravoTech page at /a-comprehensive-review-of-xvid/ (post ID 11605). Facts re-checked October 16, 2026 on xvid.com, labs.xvid.com, and VLC features. This package is a merge-candidate Draft: the live post stays untouched until an editor merges. No encode/play/convert tests and no screenshots for this rewrite.
What is Xvid?
Xvid is a free video codec that compresses video using the ISO MPEG-4 standard (commonly described as MPEG-4 Part 2, Advanced Simple Profile). Xvid’s site says it can compress at a ratio of 200:1 or more versus uncompressed video, aims to keep a sharp picture while discarding details humans notice less, and distributes the software as free and open-source without adware bundles (xvid.com).
Xvid is explicitly lossy. The project describes it as “lossy” compression that can be seen as an MP3 for video—not “compresses without losing quality.” That older wording on many review pages is wrong.
Development status: Xvid Labs lists Xvid 1.3.7 released December 28, 2019 as the latest codec release we found on October 16, 2026. Ready-made downloads on xvid.com/download cover Windows (XP SP3 and newer, Video for Windows / DirectShow) and selected Linux packages. The homepage mentions cross-platform ports including Mac in general terms; the download page we checked does not list a macOS installer package—use VLC on Mac rather than hunting unofficial installers.
Codec vs container: Xvid, AVI, MKV, and MP4
A codec is how video frames are compressed (Xvid, H.264, HEVC). A container is the file wrapper (.avi, .mkv, .mp4) that holds video, audio, and subtitles. Saying “MKV is an Xvid format” mixes those up.
- Xvid = codec (MPEG-4 Part 2 ASP family).
- AVI = the container where Xvid video is most often found from the 2000s era.
- MKV / MP4 = other containers that can hold many codecs; they are not “Xvid formats.”
How to tell if a video uses Xvid
File extension alone is not enough (.avi can hold other codecs). Practical checks editors recommend—without claiming we ran them for this article:
- VLC: open the file › Tools › Codec Information (wording varies slightly by version) and look for MPEG-4 / Xvid / XviD in the video codec field.
- MediaInfo (separate free utility): inspect the video track for MPEG-4 Visual / XVID.
How to play Xvid files in 2026
Use VLC Media Player. VideoLAN’s features page lists MPEG-4 ASP, XviD among supported video formats, and VLC is free on Windows, Mac, Linux, iOS, and Android with no separate Xvid codec required (VLC features).
For step-by-step playback on Windows and Mac, see our guide on how to play Xvid and AVI files.
Windows
Install VLC from videolan.org, open the .avi (or other) file, and play. We are not claiming whether the built-in Windows 11 Media Player app plays every Xvid file natively—that needs a hands-on check we did not perform. If the stock player fails, VLC is the documented fallback.
Mac
Install VLC for macOS. Do not assume QuickTime plays Xvid without verification; we did not test QuickTime for this rewrite.
iPhone and iPad
Use VLC for Mobile from the App Store (US listing: VLC media player). Copy the file into the VLC app via Files, AirDrop, or VLC’s Wi-Fi sharing—not the Photos app. Ignore outdated advice to install “MX Player from the iPhone App Store”; that path does not belong in an iOS guide.
Android
Install VLC for Android from Google Play (or VideoLAN’s site), then open the file from storage. Default gallery players often lack MPEG-4 ASP / Xvid support; VLC covers that gap per VideoLAN’s format list.
Smart TVs and streaming boxes
Support varies by brand and firmware. Check the device manual for MPEG-4 ASP / Xvid / DivX-compatible AVI. If playback fails, convert to MP4 (H.264) on a computer first rather than installing random “TV codec” packages.
Do you need to download the Xvid codec?
Usually no. VLC includes its own decoders. Install the Xvid Windows package from xvid.com only if you need to encode Xvid through Video for Windows / DirectShow tools. Avoid third-party “codec packs” and mirror sites that bundle adware—Xvid markets its official build as adware-free on xvid.com.
Should you convert Xvid to MP4?
Convert when you need modern device compatibility (phones, many TVs, web uploads). Keep the original when you are archiving a master file and VLC already plays it fine.
A common free tool is HandBrake: open the AVI, choose an MP4 preset with H.264 (or H.265), and export. We did not run timed conversion tests or publish before/after file sizes for this article—treat HandBrake’s own documentation as the step reference. FFmpeg can also remux/re-encode with libxvid or to H.264; again, no command outputs from our lab here.
If you edit video for a living, our Final Cut Pro vs Premiere Pro guide covers modern NLEs—old Xvid AVI clips usually get transcoded on import.
HandBrake workflow in brief (follow HandBrake’s current UI labels): open the Xvid AVI as the source, choose an MP4 container preset such as a Fast 1080p H.264 profile if it fits your resolution, keep audio as AAC unless you have a reason not to, then Start Encode. Keep the original AVI until you confirm the new file plays in VLC on the devices you care about. We are not publishing encode times or size ratios because we did not run a timed batch for this rewrite.
Xvid and DivX both grew around the same MPEG-4 Part 2 era; DivX later became a commercial brand that also shipped newer codecs, while Xvid remained an open-source ASP encoder/decoder. For day-to-day playback in 2026 you usually do not need either codec installed if VLC is present.
Xvid vs DivX vs H.264 vs HEVC
| Codec | Standard (typical) | Licence (high level) | Typical container | Still actively released? |
|---|---|---|---|---|
| Xvid | MPEG-4 Part 2 ASP | Open source (project states free/open-source; Labs FAQ historically GPL) | Often AVI | Last Labs release Dec 28, 2019 |
| DivX | Historically MPEG-4 Part 2; later DivX products also use newer codecs | Proprietary product line | AVI / DivX / others | Commercial brand still exists; not equivalent to Xvid 1.3.7 |
| H.264 / AVC | MPEG-4 Part 10 | Patented standard; free encoders exist (e.g. x264) | MP4 / MKV | Yes — default for most phones and web video |
| H.265 / HEVC | MPEG-H Part 2 | Patented standard | MP4 / MKV | Yes — higher efficiency, wider TV support |
Is Xvid safe?
Safety check
The official site is xvid.com (downloads under /download/). Xvid states its distribution is adware-free and not bundled with malware or toolbars. The risk people hit in search results is usually fake codec download sites, not the open-source project page. Prefer VLC from videolan.org when you only need playback. We did not VirusTotal-scan an installer for this package.
FAQ
What is Xvid?
Xvid is a free, open-source MPEG-4 Part 2 video codec. It is lossy compression—not a file format—and Xvid video is usually stored in an .avi file.
Is Xvid a file format?
No. Xvid is a codec. AVI, MKV, and MP4 are containers. An .avi file might contain Xvid video, or it might contain something else.
How do I play an Xvid file on Windows, Mac, or iPhone?
Install VLC (VideoLAN lists MPEG-4 ASP / XviD). On iPhone use VLC for Mobile from the App Store and import the file into VLC—not Photos.
Do I need to install the Xvid codec?
Not for playback in VLC. Install the official Windows package from xvid.com only if you need to encode Xvid through VfW/DirectShow tools.
Is Xvid safe? Does it contain spyware?
Xvid’s official site markets an adware-free, open-source build. Spyware risk usually comes from third-party codec packs. Stick to xvid.com or VLC.
What is the official Xvid website?
https://www.xvid.com/ — releases are also tracked on https://labs.xvid.com/ (1.3.7, December 28, 2019 as of our Oct 16, 2026 check).
