MPEG-2 to 3G2 Converter

MPEG-2 to 3G2 Converter

MPEG-2 is the DVD and broadcast video standard — standard-definition, interlaced, and several megabits per second. 3G2 is the tiny mobile container that 3GPP2 defined for CDMA2000 phones. Converting MPEG-2 to 3G2 takes a DVD-grade clip and shrinks it down to a small, low-resolution file that an old CDMA handset (or a strict size limit) can handle. It is a real size and resolution drop, not a quality upgrade — re-encoding can shrink a video but cannot add back detail the smaller frame loses.

How to Convert MPEG-2 to 3G2

1. Upload Your MPEG-2 File: Drag and drop your .mpeg2, .mpg, or .mpeg file onto the page, or click "Add Files." You can queue several clips and convert them with the same settings.
2. Pick Video Codec and Audio Codec: Under Advanced Options, the 3G2 output defaults to H.264 video with AMR audio. Switch the Video Codec to H.263 or MPEG-4 Part 2 for the widest old-handset compatibility, or set the Audio Codec to AAC if your target device supports it.
3. Set Video Resolution and File Compression: Use Preset Resolutions or Width x Height to shrink the SD source to a small mobile frame, and use Quality Preset, Specific file size, or Target file size (%) to hit a size cap. You can also use Trim to keep only the part you need.
4. Convert and Download: Click Convert and download your 3G2 file. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark.

If you only need the file to play on a modern phone or PC rather than a legacy CDMA device, convert MPEG-2 to MP4 instead — H.264 MP4 keeps far more detail and plays almost everywhere. If your target phone is on a GSM/UMTS network, convert MPEG-2 to 3GP, the GSM-side sibling of 3G2.

Frequently Asked Questions

What is a 3G2 file, and how is it different from 3GP?

3G2 is a multimedia container defined by 3GPP2 for CDMA2000 mobile networks, while 3GP is the 3GPP equivalent for GSM/UMTS networks. Both are built on the same ISO base media file format as MP4 and can carry the same H.263, MPEG-4 Part 2, and H.264 video. The main differences are the network family they target and the audio codecs: 3G2 adds CDMA speech codecs such as EVRC, QCELP, and SMV, and tends to produce slightly smaller files than 3GP.

Will I lose quality converting MPEG-2 to 3G2?

Yes — expect a noticeable drop. MPEG-2 source is usually standard-definition (720×480 or 720×576), and 3G2 is built for small mobile frames at low bitrates. The conversion has to scale the picture down and compress it hard, so fine detail and sharpness are lost. That tradeoff is the whole point of 3G2: small size for constrained devices. Re-encoding can never restore detail, so keep your original MPEG-2 file if you may want a higher-quality version later.

What video and audio codecs does the 3G2 output use?

Our 3G2 output defaults to H.264 video with AMR audio. In Advanced Options you can switch the Video Codec to H.263 or MPEG-4 Part 2, which older CDMA handsets are more likely to decode, and set the Audio Codec to AAC where the target device supports it. H.264 gives the best quality-per-byte but the oldest phones may not play it.

Should I convert to 3G2 or to MP4?

Choose 3G2 only if you specifically need a file for an old CDMA phone or a strict size limit that a tiny mobile clip satisfies. For nearly every modern use — current smartphones, laptops, web upload — MP4 with H.264 is the better target: it keeps far more of the original detail and plays on essentially every current device. You can convert MPEG-2 to MP4 instead if compatibility with current hardware matters more than a tiny file.

Can I make the 3G2 file fit a specific size?

Yes. Under File Compression you can target a size three ways: Quality Preset for a quick quality-based estimate, Specific file size to name an exact target in MB, or Target file size (%) to scale relative to the source. Combining a smaller Preset Resolution with a size target gives the cleanest small file, because lowering the resolution first means the encoder spends its limited bitrate on fewer pixels.

Is it safe to upload my MPEG-2 file here?

Your file is uploaded over an encrypted (TLS) connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and files are never shared or made public. The practical limit on a large MPEG-2 file is upload time over your connection rather than anything on your device.
