Need help?3G2 to DivX Converter
.3g2 is the 3GPP2 container that CDMA feature phones recorded to; .divx is the DivX Media Format, an extension of Microsoft's AVI container carrying MPEG-4 Part 2 (Advanced Simple Profile) video. Converting between them is almost always about playback hardware: a mid-2000s DVD player, set-top box, in-car head unit or games console that advertises "DivX Certified" will happily play a .divx file from a USB stick but has never heard of 3GPP2. This page explains what each format actually is, then converts one into the other.
3G2 Format at a Glance
| Property | Value |
|---|---|
| Full name | 3GPP2 multimedia file |
| Defined by | 3rd Generation Partnership Project 2 (3GPP2) |
| Container basis | ISO base media file format, the same lineage as MP4 |
| Designed for | CDMA2000 handsets — in the US, Verizon and Sprint |
| Video codecs | H.263 and MPEG-4 Part 2, with H.264 in later files |
| Audio codecs | AMR-NB and AMR-WB, AAC, plus the CDMA voice codecs QCELP, EVRC, EVRC-B, EVRC-WB and SMV |
| Typical frame size | Small — QCIF (176x144) and QVGA (320x240) were the era's norms |
| Sibling format | .3gp, the GSM-network equivalent, accepted on this page too |
| Status | Legacy. Verizon shut down its 3G CDMA network on 31 December 2022, the last major US carrier to do so |
DivX Format at a Glance
| Property | Value |
|---|---|
| Full name | DivX Media Format |
| Container basis | An extension of the AVI container — a .divx is structurally an AVI |
| Video coding | MPEG-4 Part 2, Advanced Simple Profile |
| Audio in this converter | MP3 by default, with AAC, AC3, E-AC3 and PCM variants selectable |
| Developed by | DivX, whose codec line grew out of late-1990s MPEG-4 work and turned into a commercial product in the early 2000s |
| Why it mattered | It was the first widely used way to fit a feature-length film onto a single CD at watchable quality, and the dominant AVI codec of that era |
| Where it plays | VLC everywhere, plus a large installed base of DivX Certified DVD and Blu-ray players, TVs and consoles |
| Status today | Superseded for new encoding by H.264 and H.265, but still the format a lot of old hardware expects |
How to Convert 3G2 to DivX
- Upload Your 3G2 File: Drag and drop the
.3g2onto the page or click "From my Computer" to browse..3gpfiles are accepted here as well, and multiple clips can be queued to convert with the same settings. - Set the Quality Preset: Under "File Compression", "Quality Preset" starts on "Very High (Recommended)". Switch to "Specific file size", "Constant Bitrate", "Variable Bitrate", "Constant Quality" or "Constraint Quality" if you need to hit a size or bitrate target instead.
- Check the Audio Codec and Video resolution: The audio track defaults to MP3, which is what most DivX Certified hardware expects; AC3 is the other safe choice. "Video resolution" defaults to "Keep original" — scale up only if a player demands a minimum frame size.
- Convert and Download: Click "Convert" and save the
.divx. Files upload over an encrypted connection, are processed on our servers, and are deleted automatically after a few hours. No sign-up, no watermark.
What Changes in the Conversion
The server decodes the 3G2 and re-encodes it as MPEG-4 ASP video with an MP3 soundtrack inside an AVI-based .divx file. Two things follow from that:
- This is a generational re-encode, not a repackage. Your source is already lossy H.263 or MPEG-4 video from a phone; encoding it again into MPEG-4 ASP adds a second lossy pass. Keeping "Quality Preset" at "Very High (Recommended)" keeps that second pass close to invisible.
- The audio is rebuilt, and that is usually good news. CDMA voice codecs like QCELP and EVRC are narrowband speech codecs that almost nothing outside a phone can decode. Re-encoding them to MP3 is what makes the file playable at all on a DVD player or TV.
Frequently Asked Questions
Is a .divx file just an AVI with a different extension?
Structurally, close to it. DivX Media Format is an extension of the AVI container, so a .divx file is an AVI carrying MPEG-4 Part 2 video and, here, MP3 audio, plus the format's own additions for things like multiple audio tracks and chapters. Practically, the extension is a compatibility signal: some DivX Certified devices look for .divx or .avi and ignore anything else on the USB stick. If a player refuses the file, renaming it to .avi is the first thing to try.
Why would anyone still convert to DivX in 2026?
Hardware. There is a very large installed base of DVD players, Blu-ray decks, older smart TVs, games consoles and car head units from the mid-2000s onward that were sold as DivX Certified and will play MPEG-4 ASP in an AVI container off USB or a burned disc — but will not play a 3GPP2 file, and often will not play modern H.264 in MP4 either. If your target is a computer or a phone instead, 3G2 to MP4 is the better conversion by every technical measure.
Should I leave the audio codec on MP3?
Usually yes. MP3 is the default on this page and is the audio codec DivX Certified hardware is most reliably able to decode inside an AVI-based file; AC3 is the other one that older home-theatre gear generally handles. The more modern options in the "Audio Codec" list — AAC, E-AC3, FLAC, Opus-era codecs — are fine if the file is destined for VLC on a computer, but they are exactly the sort of thing that makes an old set-top box show a silent picture.
Will the video look better after converting to DivX?
No. A conversion cannot recover detail that a CDMA-era handset never captured. Video from that era was commonly encoded at QCIF or QVGA frame sizes at low bitrates and low frame rates, and every one of those limits is baked into the file you are uploading. What DivX gives you is a container and codec that old hardware can decode; the picture itself will look like phone video from the 2000s, only now on a bigger screen where the softness is more obvious.
Should I upscale the resolution so it fills my TV?
Generally not here. Leaving "Video resolution" on "Keep original" produces the smallest, cleanest file, and almost every TV and player will scale it to the screen on playback anyway — doing that in the player is no worse than doing it in the encoder, and it keeps the file small. The one reason to scale up in the conversion is a stubborn device that refuses frame sizes below some minimum. In that case pick a "Preset Resolutions" value just above the threshold rather than jumping to 1080p.
Can I cut out just part of the clip?
Yes. "Trim" starts on "Unchanged"; switch it to "Time Range" and set a start point and a duration to export only that section. This is worth doing before you burn a disc or fill a USB stick with recovered phone footage, since it saves re-encoding the parts you do not want. For heavier editing across several clips, the dedicated video cutter is the better tool.
What is the difference between DivX and Xvid?
They are two implementations of the same underlying idea: MPEG-4 Part 2 Advanced Simple Profile video, usually in an AVI container. DivX is the commercial line with the certification programme that hardware makers licensed; Xvid is the open-source encoder that grew up alongside it. Files from either usually play on the other's decoder, which is why DivX Certified devices are generally happy with Xvid-encoded AVIs too. The 3G2 to AVI converter covers the plain-AVI route if you do not specifically need the .divx extension.
How are my uploaded files handled?
Your 3G2 is uploaded over a TLS-encrypted connection, converted on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark on the output, and files are never shared or made public. If DivX turns out not to be what your device wants, the 3G2 converter hub lists every other target this source can be converted into.
