Do not use UWP (Universal Windows Platform) apps for Xvid.

As of 2017, the Xvid video codec remained a widely used, open-source implementation of the MPEG-4 Advanced Simple Profile (ASP) standard. For Windows 10 users, Xvid was not natively supported by the operating system’s built-in media players (e.g., Windows Media Player or the new UWP "Movies & TV" app). Consequently, users in 2017 faced a choice: install a standalone DirectShow filter (codec pack) or utilize a modern media player with internal decoders (e.g., VLC, MPC-HC). This report analyzes the codec’s technical status, compatibility, installation methods, performance, and security landscape specifically for Windows 10 in 2017.

| Feature | Xvid (MPEG-4 ASP) | H.264 (MPEG-4 AVC) | | :--- | :--- | :--- | | | Older (circa 2001) | Modern Standard | | Efficiency | Lower (Larger file sizes for same quality) | High (Smaller files, better quality) | | Hardware Acceleration | Limited / Rare | Ubiquitous (GPU decoding standard) | | Resolution Support | Optimized for SD (480p) | Optimized for HD/4K | | Windows 10 Support | Requires 3rd Party Codecs | Native support (mostly) |
