Need help?CAVS to DivX Converter
CAVS is a Chinese AVS-based video format that almost nothing outside China plays natively, so a .cavs file is awkward to share or open on a typical PC or media player. Converting it to DivX re-wraps the video in the older MPEG-4 Part 2 codec that DivX-certified standalone DVD players and home-theater boxes understand. Transcoding never adds detail the source lacks — if your goal is just modern, universal playback, CAVS to MP4 (H.264) gives a smaller, more widely supported file. Pick DivX only when you specifically need an old DivX/Xvid-certified player to read the disc or USB stick.
CAVS Format at a Glance
| Property | Value |
|---|---|
| Full name | Chinese AVS (Audio Video Coding Standard, AVS1) |
| Defined by | AVS Working Group of China (founded 2002) |
| Standardized | AVS1 finalized 2003; ratified as a Chinese national standard in February 2006 |
| Codec family | AVS1-P2 video — comparable efficiency to H.264/AVC, but omits the most complex tools (no CABAC, no MBAFF) |
| Typical use | Digital TV broadcast, IPTV, and DVD/home-theater players in China |
| Playback outside China | Very limited; rarely supported by mainstream desktop or mobile players |
DivX Format at a Glance
| Property | Value |
|---|---|
| What it is | A video codec family from DivX, LLC; the classic .divx codec is MPEG-4 Part 2 (Advanced Simple Profile) |
| Container | AVI-based (DivX Media Format extends the RIFF/AVI structure) |
| Released | OpenDivX January 2001; DivX 4.0 July 2001 — same encoding core that Xvid later forked from |
| Audio | Commonly MP3 or AC3 alongside the video stream |
| Where it shines | DivX-certified standalone DVD/Blu-ray players, older smart TVs, and set-top boxes |
| Modern alternative | H.264 in MP4 is smaller at equal quality and plays nearly everywhere |
How to Convert CAVS to DivX
- Upload Your CAVS File: Drag and drop your .cavs file onto the page or click "+ Add Files" to select it. You can queue several files and convert them with the same settings.
- Confirm DivX Output and Codec: The output is set to DivX with the DivX (MPEG-4 Part 2) video codec and MP3 audio by default; switch the Audio Codec to AC3 under Advanced Options if your target player prefers it.
- Set Quality, Resolution, or Trim (Optional): Use the Quality Preset (defaults to Very High), pick a Video Resolution preset or enter a Width x Height, or use Trim to keep only a time range.
- Convert and Download: Click "Convert" and download your DivX file. Files upload over an encrypted connection, are processed on our servers, and are deleted automatically after a few hours — no sign-up, no watermark.
Frequently Asked Questions
Will converting CAVS to DivX improve the video quality?
No. Re-encoding can only preserve or reduce the detail already in the source; it cannot add resolution or sharpness that the original CAVS file never captured. DivX (MPEG-4 Part 2) is also an older, less efficient codec than H.264, so at a matching file size it generally looks slightly softer than an MP4 conversion. Convert to DivX for playback compatibility, not for a quality upgrade.
Why convert CAVS to DivX instead of MP4?
The one real reason is hardware: DivX-certified standalone DVD players, older smart TVs, and set-top boxes can read DivX/Xvid files from a disc or USB stick but were never designed to decode Chinese AVS. If you only need the clip to play on a computer, phone, or modern TV, MP4 (H.264) is smaller and far more universally supported, so DivX is the niche choice for legacy living-room hardware.
What is a .cavs file and why won't it play on my computer?
A .cavs file holds video encoded with Chinese AVS (AVS1), China's national video coding standard ratified in 2006. It was built for Chinese digital TV and DVD/home-theater equipment, so mainstream desktop and mobile players usually lack the decoder. Converting it to DivX (or MP4) re-encodes the video into a codec your device already understands.
Does the DivX output use MP3 or AC3 audio?
By default this converter pairs the DivX video stream with MP3 audio, which virtually every DivX-certified player handles. If your target device expects surround sound or specifically lists AC3 support, switch the Audio Codec to AC3 in Advanced Options before converting. In our testing, MP3 is the safest default for older standalone players, while AC3 is worth choosing for home-theater receivers that decode it.
Is DivX the same thing as Xvid?
They are closely related but not identical. Both descend from the same MPEG-4 Part 2 encoding core, which split in 2001 when the open-source Xvid project forked away from DivX. Most DivX-certified hardware also plays Xvid files, and both produce AVI-style files, but DivX is the commercial brand with the official certification program.
What file size can I upload?
There is no hard per-file cap published for this tool; the practical limit is upload size and time over your connection, so very large or long videos take longer to send and process. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — never shared or made public. For batch jobs, the video converter hub lets you queue multiple files at once.
