Why Convert WMV to 3G2?
WMV (Windows Media Video) is Microsoft's video format — common on Windows PCs but not supported on most mobile phones. 3G2 is a mobile video format for CDMA2000 networks (Verizon, Sprint). Converting WMV to 3G2 is useful for sending Windows video via MMS on legacy CDMA phones, creating small video files from WMV recordings for mobile delivery, maintaining compatibility with older Verizon/Sprint feature phones, and dramatically reducing file size for bandwidth-limited transfers.
WMV vs 3G2 Comparison
| Feature | WMV | 3G2 (3GPP2) |
|---|---|---|
| Developer | Microsoft | 3GPP2 (CDMA consortium) |
| Video codec | WMV9 | H.264 (default) |
| Audio codec | WMA | AMR (default) |
| File size | Medium-large | Very small |
| Platform | Windows | CDMA mobile phones |
| Best for | Windows playback | Legacy CDMA phones, MMS |
Why is AMR the default audio codec?
AMR (Adaptive Multi-Rate) is the native audio codec for 3G2 — designed for voice on CDMA mobile networks. AMR produces very small files but is voice-optimized. Change to AAC under Audio Codec for better music quality.
How much smaller will the 3G2 file be?
Significantly smaller. A 50 MB WMV file typically becomes 5-15 MB as 3G2 at 360p. The reduction comes from both H.264's efficient compression and the lower resolution typical for mobile video.
What resolution should I use?
3G2 is designed for mobile screens. Use 320×240 (QVGA) for feature phones or 640×480 for smartphones. Higher resolutions work but defeat the purpose of 3G2's small file size.
Can I trim the video during conversion?
Yes. Under Trim, select "Time Range" and enter a Start Time and Duration in seconds or HH:MM:SS.sss format.
Should I use 3G2 or MP4?
For modern devices, use WMV to MP4. 3G2 is only needed for legacy CDMA feature phones and MMS with strict file size limits.
What is the difference between 3G2 and 3GP?
3G2 is for CDMA networks (Verizon, Sprint), while 3GP is for GSM networks (AT&T, T-Mobile). Both are nearly identical containers. 3G2 additionally supports EVRC and QCELP audio codecs used in CDMA voice networks.
