Need help?How to Convert MPEG to 3G2
- Upload Your MPEG File — Click "Choose Files" or drag and drop your MPG or MPEG video file. Both extensions are accepted.
- Choose Video Codec — Under Video Codec, the default for 3G2 output is H.264. H.263 is also available for maximum legacy compatibility.
- Set Video Quality — Under File Compression, choose from: Quality Preset (Highest through Lowest), Target File Size % (1-100% slider with Smart Scaling), Specific File Size (MB/KB), Constant Bitrate, Variable Bitrate, Constant Quality (CRF), or Constraint Quality.
- Set Audio Codec — Under Audio Codec, the default for 3G2 is AMR (Adaptive Multi-Rate).
- Adjust Resolution (Optional) — Under Video Resolution, keep the original or choose Preset Resolutions (480p, 360p, 240p, etc.) or custom dimensions. 3G2 is designed for small screens.
- Trim (Optional) — Under Trim, set a Start Time and Duration to extract a specific segment.
- Convert & Download — Click "Convert" and download your 3G2 file.
Why Convert MPEG to 3G2?
3G2 (3GPP2) is a mobile video format designed for CDMA2000 networks used by carriers like Verizon and Sprint. Converting MPEG to 3G2 dramatically reduces file size — a 100 MB MPEG file typically becomes 15-25 MB as 3G2 while maintaining acceptable quality for mobile screens. This is useful for sending video via MMS on legacy CDMA phones, creating small video files for low-bandwidth mobile delivery, maintaining compatibility with older Verizon/Sprint feature phones, and preparing DVD-era MPEG recordings for mobile viewing.
MPEG vs 3G2 Comparison
| Feature | MPEG | 3G2 (3GPP2) |
|---|---|---|
| Video codec | MPEG-1 or MPEG-2 | H.264 (default) |
| Audio codec | MP2 | AMR (default) |
| File size (1 min) | 10-50 MB | 1-5 MB |
| Resolution | Up to 1080p | Typically 320×240 or 640×480 |
| Network | Broadcast, DVD | CDMA2000 mobile |
| Best for | DVD, digital TV | Legacy CDMA phones, MMS |
Recommended 3G2 Settings
| Use Case | Resolution | Bitrate |
|---|---|---|
| Feature phone MMS | 240p (320×240) | Low (Constant Bitrate) |
| Smartphone playback | 480p (640×480) | Medium (Quality Preset) |
| Maximum quality | 720p | High (Quality Preset: Highest) |
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 100 MB MPEG file typically becomes 15-25 MB as 3G2 at 480p. The size reduction comes from both the more efficient H.264 codec and the lower resolution typical for mobile video.
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.
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.
Should I use 3G2 or MP4?
For modern devices, use MPEG to MP4. 3G2 is only needed for legacy CDMA feature phones and MMS with strict file size limits.
