Need help?How to Convert Video to DivX Online
- Upload Your Video File: Drag and drop or click "+ Add Files" to choose MP4, MOV, MKV, AVI, WebM, AVCHD, MTS, FLV, WMV, VOB, or 30+ other video formats. Batch upload is supported — every file in the queue inherits the same settings.
- Pick a Quality Preset or Target File Size: "Very High" is the default and matches the DivX Home Theater profile well for SD/HD content. Switch to "Specific file size" to hit an exact MB target (default 24 MB), "Constant Bitrate" to lock the rate (default 4 Mbps, max 8 Mbps), or "Variable Bitrate" for a 2–8 Mbps adaptive range. The output uses the DivX (DX50) MPEG-4 Part 2 video codec paired with MP3 audio by default — the combo certified DivX players expect.
- Set Resolution and Trim (Optional): Pick a preset (768p default, plus 1080p, 720p, 480p) or enter custom width × height. DivX Home Theater certified DVD players cap out at 720×480; DivX HD at 1280×720; DivX Plus HD at 1920×1080. Use "Trim → Time Range" to keep only the clip you need (defaults to first 10 seconds, adjustable).
- Convert and Download: Click "Convert". Files are processed on our servers, then auto-deleted — no sign-up, no watermark, no DivX Pro license needed.
Why Convert Video to DivX?
DivX is a family of MPEG-4-based video codecs developed by DivX, LLC since 1998. The classic DivX codec (DX50) is built on MPEG-4 Part 2 and ships in an AVI-derived container — files use either .avi or .divx. DivX peaked in the 2005–2012 era when DivX Certified DVD players, Blu-ray decks, and early smart TVs from Philips, LG, Panasonic, Samsung, Sharp, Toshiba, and Sony were the only mainstream way to play "downloaded" video on a TV. Modern phones default to H.264/HEVC, but a surprising amount of consumer hardware in the wild still expects DivX.
- DivX Certified DVD and Blu-ray players — More than 1,500 set-top devices were DivX Plus HD certified, mostly between 2005 and 2015. If a player has the DivX logo on the front panel, it plays DX50-encoded AVI/DIVX files off a USB stick or burned data disc, where it would refuse MP4 or MKV.
- Older smart TVs and car head units — Pre-2018 TVs and aftermarket double-DIN car decks (Pioneer AVH-, Kenwood DDX-, Sony XAV-) commonly list "DivX/Xvid" in their spec sheets but don't decode HEVC or VP9. DivX is the lingua franca for these screens.
- Long-tail archival and home theater libraries — Many people built their digital movie collections in DivX during the 2000s. Re-encoding new captures to DivX keeps the entire library on one codec for a single Plex/Kodi profile or a portable hard drive that gets plugged into the living-room player.
- DVD authoring with extra runtime — A single-layer DVD-R holds 4.7 GB. MPEG-2 (the DVD-Video standard) gets you about 90 minutes at decent quality; the same disc burned as DivX/AVI data fits 4–6 hours, and any DivX Certified player handles it.
- Cross-platform playback on legacy Windows/Mac without re-installing codecs — DivX Player, VLC, and MPC-HC all decode DX50 out of the box, so a DivX file is a safer bet than a fresh-format MP4 on a relative's 2012 PC.
- Smaller file sizes than the source on legacy formats — Re-encoding a fat MPEG-2 VOB or HuffYUV capture to DivX typically cuts the file 60–80% with no visible quality loss at 720p.
DivX vs Xvid vs H.264 — Format Comparison
| Property | DivX (DX50) | Xvid | H.264 (MP4) |
|---|---|---|---|
| Underlying standard | MPEG-4 Part 2 (ASP) | MPEG-4 Part 2 (ASP) | MPEG-4 Part 10 (AVC) |
| License | Proprietary, DivX LLC | Open source, GPL | Patented, royalty pool |
| Typical container | .avi or .divx | .avi | .mp4, .mov, .mkv |
| Best for | DivX Certified hardware | Cross-codec hardware that lists "Xvid" | Modern phones, web, streaming |
| Hardware-decode support | DVD/Blu-ray players, older TVs, head units | Same player class, often paired with DivX | Universal: phones, browsers, TVs since ~2010 |
| Compression efficiency at 1080p | Baseline | ~Equal to DivX | 40–50% smaller for same quality |
| Max resolution (profiles) | 1080p (DivX Plus HD) | 1080p in practice | 4K, 8K |
| FourCC | DX50 | XVID | avc1 / h264 |
H.264 wins on efficiency every time. Pick DivX or Xvid only when the target device's spec sheet says so — for a 2024 phone, MKV, or YouTube upload, go with MP4 instead.
Quality Preset and Bitrate Guide
| Setting | Use when... | Typical bitrate |
|---|---|---|
| Quality Preset "Very High" (default) | You don't care about exact file size; just want it to look right on a DivX player | ~4–6 Mbps at 720p |
| Quality Preset "High" | Stretching a 2-hour movie onto a 4.7 GB DVD-R | ~2–3 Mbps at 720p |
| Specific file size | You need to fit a USB stick / WhatsApp / disc slot | Auto |
| Constant Bitrate (CBR) | Streaming the file to a strict-bitrate device | 4 Mbps (default) |
| Variable Bitrate (VBR) | Best quality-per-MB for archival | 2–8 Mbps range |
| Constant Quality (CRF) | You want predictable visual quality across mixed source clips | n/a (CRF-based) |
Frequently Asked Questions
Will the output be a .avi or a .divx file?
The output extension is .divx. The internal structure is the DivX Media Format — an extension of AVI — so any player that handles legacy AVI files will also play it as long as it has the DX50/MPEG-4 Part 2 decoder. If your target device specifically expects .avi, use the Video to AVI converter or rename the file (the byte layout is compatible).
My DivX Certified DVD player still won't play the file. Why?
Three common causes: (1) the resolution exceeds the player's profile — Home Theater profile maxes at 720×480, so cap encodes at SD if the deck pre-dates the DivX HD logo; (2) the bitrate is too high — most early players cap at 4 Mbps average and 8 Mbps peak; (3) the audio codec is unsupported — DivX Certified players expect MP3, MP2, or AC-3, not AAC or Opus. Switch the Audio Codec to "MP3" in Advanced Options if you used a different default.
Should I pick DivX or Xvid?
If the device's spec sheet lists both, DivX (DX50) tends to have slightly better compression and broader certified-hardware reach. If the device only lists Xvid, pick Xvid — Xvid is an open-source MPEG-4 Part 2 implementation and uses the FourCC XVID instead of DX50, which some firmware checks strictly. The two are technically interchangeable on most modern players.
Is DivX still relevant in 2026 or should I just use MP4?
For any modern phone, browser, social media upload, or 2018+ smart TV: use MP4 with H.264 or HEVC. DivX is only the right answer when you're feeding a DivX Certified DVD player, an older Blu-ray deck without MKV support, an aftermarket car head unit that lists DivX/Xvid, or maintaining a legacy library that's already standardized on the codec.
What's the maximum resolution and bitrate DivX supports?
The DivX codec itself can be pushed to 1080p — that's the DivX Plus HD profile limit and what most certified devices accept. DivX HEVC (a separate codec marketed under the same brand since 2014) extends to 4K, but it's a different decoder and most legacy DivX Certified players don't support it. For DX50/MPEG-4 Part 2 specifically, sane bitrates are 1–8 Mbps; anything higher wastes bits because the codec can't make use of them.
Does the converter add a DivX watermark or trial limit?
No. xconvert is free, no sign-up, no watermark, no DivX Pro license required. We're running an open-source encoder (FFmpeg's MPEG-4 Part 2 implementation) that produces DX50-tagged streams compatible with DivX Certified players. The DivX, LLC's own free "DivX Software" desktop converter is also unlimited but requires installation.
Can I convert a 4K HEVC video down to DivX?
Yes, but you'll lose resolution detail — set a 1080p or 720p preset before converting, because DivX (DX50) maxes out at 1080p. Going from HEVC 4K to DivX 720p typically produces a 60–80% smaller file with quality acceptable for legacy hardware playback. The file won't look as sharp as the source on a 4K TV — that's expected.
Will subtitles and multiple audio tracks survive the conversion?
The DivX Media Format (.divx) supports multiple audio tracks and chapter points natively, but in this converter we output a single video + single audio stream for maximum certified-player compatibility. If you need multi-track output, encode each track separately or use MKV as an intermediate.
How does this compare to just compressing my existing video without changing the format?
If your source is already in a hardware-friendly format and you just want a smaller file, use the Video Compressor instead — re-encoding to a different codec always loses some quality, even if barely visible. Convert to DivX only when the playback device specifically requires it.
