How to Trim 3G2 Videos

1. Upload your 3G2 file — Click "+ Add Files" or drag and drop your 3G2 or 3GP mobile video.
2. Set trim points — Under "Trim," select "Time Range" and enter a start time and duration.
3. Adjust compression (optional) — Under "File Compression," select "Quality Preset" (Highest to Lowest), "Target file size (%)", "Specific file size," "Constant Bitrate," "Variable Bitrate," "Constant Quality" (CRF), or "Constraint Quality."
4. Adjust resolution (optional) — Under "Video resolution," keep original, pick a preset (480p, 360p, etc.), or enter exact width/height.
5. Trim and download — Click "Trim" and download your trimmed 3G2 file.

Why Trim 3G2 Files?

3G2 (3GPP2) is the CDMA variant of the 3GP mobile video format, used by phones on Verizon, Sprint, and other CDMA networks in the 2000s–2010s. Like 3GP, these are low-resolution recordings from older mobile phones that may need trimming to extract specific moments or remove unwanted sections.

3G2 and 3GP are nearly identical formats — the main difference is the network standard (CDMA vs GSM). This tool accepts both extensions.

Frequently Asked Questions

Can I upload both 3G2 and 3GP files?

Yes. Both .3g2 and .3gp are accepted. The formats are nearly identical — 3G2 is the CDMA variant, 3GP is the GSM variant.

Can I compress while trimming?

Yes. Under "File Compression," choose any method. Since 3G2 files are already small and low-resolution, compression has limited benefit.

Should I trim as 3G2 or convert to MP4?

For modern use, 3G2 to MP4 is strongly recommended — MP4 plays everywhere. Keep 3G2 only for legacy CDMA phone compatibility.

Can I also resize while trimming?

Yes. Under "Video resolution," change resolution — though most 3G2 content is already low-resolution (176×144 or 320×240).

What is the difference between 3G2 and 3GP?

3G2 was designed for CDMA networks (Verizon, Sprint). 3GP was designed for GSM networks (AT&T, T-Mobile). The video/audio codecs and quality are identical — only the network metadata differs.
