Supports: DIVX
DivX began as a modified Microsoft MPEG-4 codec around 1998 and matured through DivX 4 (2001), DivX 5 (2002) and DivX Plus HD with H.264. The .divx extension is essentially an AVI container carrying MPEG-4 Part 2 video, and most files in the wild date from the 2000-2010 era. WMV (Windows Media Video) is Microsoft's family of codecs — WMV 7, 8 and 9 — usually wrapped in an ASF container with the .wmv extension. Microsoft submitted WMV 9 to SMPTE and it was ratified as VC-1 (SMPTE 421M) in March 2006, becoming one of the three mandatory codecs on Blu-ray. Both formats are legacy today, but a WMV target still makes sense in a Windows-first workflow.
.divx..wmv while blocking third-party codec installers.| Property | DivX (.divx) | WMV (.wmv) |
|---|---|---|
| Underlying codec | MPEG-4 Part 2 ASP (DivX 4-6); H.264 in DivX Plus HD | WMV 7 / 8 / 9 — WMV 9 standardized as VC-1 (SMPTE 421M, 2006) |
| Container | DivX Media Format, a RIFF/AVI extension | Advanced Systems Format (ASF) |
| Developer | DivX, LLC (originally a Project Mayo fork of MS MPEG-4 v3) | Microsoft |
| Peak relevance | ~2000-2010 | ~2003-2015 |
| Windows 11 playback out of the box | Requires DivX codec or VLC | Native in Windows Media Player Legacy / Media Player |
| Streaming server support | Limited — relied on progressive download | Windows Media Services, IIS Smooth Streaming |
| Subtitles | XSUB (DivX 6 DMF) | Embedded text / SAMI / closed captions in ASF |
| DRM | None in the open spec | Optional WMDRM / PlayReady |
| Blu-ray mandatory codec | No | Yes (as VC-1) |
| Modern recommendation | Re-encode to MP4/H.264 | Re-encode to MP4/H.264 or WebM for the open web |
| Video Codec setting | What you get | When to pick it |
|---|---|---|
| WMV2 (default) | Windows Media Video 8, ~2001 vintage | Maximum compatibility with old Windows boxes and embedded WMP controls |
| WMV3 / VC-1 | Windows Media Video 9 / VC-1 | Better quality per bit; the codec ratified for Blu-ray |
| H.264 | AVC inside an ASF wrapper | Smallest file at given quality; needs a modern player |
| H.265 (HEVC) | HEVC in ASF | Even smaller files; playback support outside Windows is patchy in .wmv form |
| MPEG-4 | MPEG-4 Part 2 (Simple/ASP) | Closest to the source if your .divx was MPEG-4 ASP — minimizes generational loss |
WMV2 (the default) is the safest pick when the target machine is a stock Windows install with Windows Media Player Legacy — it plays without any extra setup. WMV3 (which is the WMV 9 / VC-1 codec) offers noticeably better quality per bit and is still natively supported by Windows Media Player. Pick H.264 only if you control the playback environment and know it has an H.264-capable player; you get a smaller file, but you give up the "plays on every Windows box" property that's the main reason to choose .wmv in the first place.
Yes — any re-encode between two lossy codecs loses some quality. To minimize it, set Quality Preset to "Very High" or use Constant Quality (CRF) with a low value (the lower the CRF, the better the quality and the larger the file). If your source .divx is MPEG-4 Part 2, picking the MPEG-4 video codec in the WMV container keeps the encoder family closest to the original and reduces visible artifacts compared with re-encoding to WMV2.
A clean install of Windows 11 ships codecs for WMV, MP3, WAV and AVI but does not include the DivX codec. Windows Media Player Legacy will open the AVI container but show "Windows Media Player cannot play the file" because the DivX-tagged MPEG-4 stream needs the DivX codec pack or VLC. Re-encoding to WMV2 sidesteps that — the file plays without installing anything.
WMA v2 is the default and is the audio counterpart to WMV in Windows Media Player — pick it if your priority is "double-click and play on Windows". Switch Audio Codec to AAC if the file will be opened in PowerPoint, edited in modern NLE software, or moved into a future MP4 — AAC re-muxes losslessly to MP4 later. MP3 is a safe middle ground supported by virtually every player.
For anything outside a Windows-only environment, MP4 with H.264 is the better choice — it plays natively on iOS, Android, macOS, every modern browser through HTML5 <video>, and every smart TV. WMV remains useful for Windows Media Player Legacy, older Windows Media Services deployments, and PowerPoint workflows that embed video. For a universal output, use DivX to MP4 instead.
Yes. Under Trim, switch from "Unchanged" to "Time Range" and enter Start Time and Duration in seconds or HH:MM:SS.sss. Under Video Resolution, set a Preset Resolution (for example 720p) or enter Width x Height. Both operations are applied in the same single conversion pass, so you don't suffer two generations of re-encoding.
For the same visual quality at 720p or 1080p, WMV2 typically produces a slightly larger file than the original DivX (which is MPEG-4 ASP) because WMV2 is an older-generation codec. If you switch the Video Codec to H.264 inside the WMV container, the output will usually be smaller than the source DivX. Use "Specific file size" if you need to hit an exact target, or Compress WMV on the output if it's still too big.
Partially. ASF supports embedded text streams, SAMI captions and closed captions, but it doesn't carry DivX's XSUB image-based subtitles or DMF chapter markers directly. If your .divx source has XSUB subtitle tracks or chapters, those won't survive the conversion — extract them separately first if you need them in the output.
.wmv still a sensible target in 2026, or should I go straight to MP4?WMV is a legacy format. Choose it when the receiving environment is specifically a Windows machine with Windows Media Player Legacy, a Windows Media Services backend, or a locked-down kiosk that won't accept third-party codecs. For everything else — phones, browsers, macOS, Linux, modern smart TVs — convert your DivX to MP4 instead via DivX to MP4, or re-target an existing WMV library with WMV to MP4.
