Bring Your Old Mobile Videos Into the HD Era

Have 3G2 videos from an old CDMA phone sitting on your computer? These files were designed for early mobile devices with limited storage and bandwidth, often capping at 320x240 resolution. If you need to edit these clips in professional software like Adobe Premiere or Final Cut Pro, or want to burn them to Blu-ray, the 3G2 format creates compatibility headaches.

Converting to MTS (AVCHD) gives your legacy footage a proper container for modern HD workflows. While conversion cannot add detail that was not originally captured, MTS provides superior codec efficiency and universal support in professional editing suites.

How to Convert 3G2 to MTS

  1. Upload your 3G2 file - Drag and drop your CDMA mobile video or click to browse. We accept files from your device, Google Drive, or Dropbox.
  2. Confirm MTS as output - The converter automatically selects optimal H.264 encoding settings for AVCHD compatibility.
  3. Download your MTS file - Processing typically completes in under a minute. Your converted HD-ready file downloads instantly.

No software installation required. The entire conversion happens in your browser using secure, encrypted processing.

Understanding 3G2 and MTS Formats

3G2 (3GPP2) was developed by the Third Generation Partnership Project 2 for CDMA2000 mobile networks. Based on the ISO base media file format (MPEG-4 Part 12), it typically contains H.263 or MPEG-4 video with AMR, EVRC, or QCELP audio. The format prioritizes minimal file size over quality, with most recordings limited to QVGA (320x240) resolution.

  • 3G2 video codecs: H.263, H.264, MPEG-4 Part 2
  • 3G2 audio codecs: AMR, EVRC, EVRC-B, 13K (QCELP), SMV
  • Typical resolution: 176x144 (QCIF) to 352x288 (CIF)

MTS is the file extension for AVCHD (Advanced Video Coding High Definition), jointly developed by Sony and Panasonic in 2006. It uses H.264/AVC compression within an MPEG-2 Transport Stream container, supporting resolutions from 720p to 1080p with Dolby Digital or PCM audio.

  • MTS video codec: H.264/MPEG-4 AVC
  • MTS audio codecs: Dolby AC-3, Linear PCM (stereo or 5.1 surround)
  • Supported resolutions: 720p, 1080i, 1080p at 24/25/30/50/60 fps

When 3G2 to MTS Conversion Makes Sense

Professional Video Editing

Adobe Premiere Pro, DaVinci Resolve, and Final Cut Pro handle MTS natively as it is the standard camcorder format. If you are compiling old mobile footage into a documentary or family video project, converting to MTS ensures smooth timeline playback and proper codec recognition.

Blu-ray Disc Creation

AVCHD was designed for optical disc compatibility. Converting your 3G2 clips to MTS allows direct import into Blu-ray authoring software without additional transcoding steps. The MTS format maintains the exact container structure that Blu-ray players expect.

Archival with Future-Proof Container

While 3G2 support is declining as CDMA networks sunset, MTS remains widely supported due to its Blu-ray heritage. Archiving in MTS ensures your videos remain accessible for decades.

3G2 vs MTS: Choosing the Right Format

This conversion involves upgrading from a mobile-optimized format to a professional HD container. Understanding the trade-offs helps set realistic expectations.

  • Choose MTS when: You need professional editing software compatibility, Blu-ray authoring capability, or a standardized archival format with broad device support.
  • Keep 3G2 when: Storage space is critical, you only need playback on mobile devices, or the original quality is sufficient for your purpose.
  • Consider 3G2 to MP4 when: You want maximum compatibility across web browsers, streaming platforms, and social media without the overhead of AVCHD structure.

Important: Converting from 3G2 to MTS does not magically enhance resolution. A 320x240 source video will retain its original detail level; the MTS container simply provides better codec efficiency and professional workflow compatibility.

Batch Convert Multiple 3G2 Files

Migrating an entire archive of old mobile videos? Our batch processing handles multiple 3G2 files simultaneously. Upload your collection, and each file converts to MTS with consistent settings. This is particularly useful when digitizing years of CDMA phone footage for a family archive project.

Works on Any Device

Our 3G2 to MTS converter runs entirely in your browser. No software downloads, no plugins, no compatibility concerns. Whether you are on a Windows workstation, MacBook, Linux desktop, Chromebook, or even a tablet, the conversion works identically.

  • Windows 10/11, macOS, Linux, Chrome OS
  • Chrome, Firefox, Safari, Edge browsers
  • iPhone, iPad, Android devices

Your files are processed securely and automatically deleted after conversion. We never store or access your personal videos.

Pro Tip

Before converting your entire 3G2 archive, test one file in your editing software. Some NLE timelines struggle with sub-HD footage regardless of container format. You may need to create a proxy workflow or upscale to 720p during import for smooth timeline scrubbing.

Common Mistake

Users often expect MTS conversion to magically enhance their old mobile footage to HD quality. The container upgrade improves compatibility and codec efficiency, but cannot recover detail that was never captured. Set realistic expectations for 15-year-old phone videos.

Best For

Perfect for importing legacy CDMA phone videos into professional editing software like Premiere Pro or DaVinci Resolve, or preparing clips for Blu-ray authoring projects that require AVCHD format.

Not Recommended

Not ideal if you just want to share videos online or play them on modern devices. For general use, converting 3G2 to MP4 provides better compatibility with web browsers, social media platforms, and smartphones without the overhead of AVCHD structure.

Frequently Asked Questions

No. Conversion changes the container format and codec, but cannot add detail that was not originally captured. A 320x240 3G2 video will remain 320x240 in MTS. However, MTS uses more efficient H.264 compression which can preserve existing quality better during editing and re-encoding.

MTS (AVCHD) is the native format for professional camcorders and Blu-ray authoring. If you plan to edit in Premiere Pro, Final Cut, or burn to Blu-ray disc, MTS provides seamless compatibility. For web sharing or general playback, MP4 is typically more practical.

Most professional editors have limited or no 3G2 support since it was designed for mobile phones, not post-production. Converting to MTS ensures proper import, timeline playback, and export compatibility in Adobe Premiere, DaVinci Resolve, and Final Cut Pro.

We encode audio as Dolby Digital (AC-3) stereo at 256 kbps, which is the standard for AVCHD. This maintains full compatibility with Blu-ray players and professional editing software while providing better quality than the original AMR or EVRC audio in most 3G2 files.

Most 3G2 files from mobile phones are under 50MB and convert in 30-60 seconds. Larger files or batch conversions take proportionally longer. Processing speed depends on your internet connection for upload/download and our server load.

MTS files must be authored onto a Blu-ray disc with proper folder structure (BDMV/STREAM) to play on standalone players. The converted file is compatible with Blu-ray authoring software, but you cannot simply copy the raw MTS file to a disc and expect playback.

Major carriers like Verizon and Sprint sunset their CDMA networks between 2020-2022. While the networks are gone, millions of 3G2 video files remain on computers and backup drives. Converting to MTS future-proofs these memories in a widely supported format.

Yes. Our converter handles all standard 3G2 audio codecs including AMR, EVRC, EVRC-B, EVRC-WB, 13K (QCELP), SMV, and VMR-WB. The audio is transcoded to Dolby Digital for MTS compatibility regardless of the source codec.

Free conversion supports files up to 100MB, which covers the vast majority of 3G2 mobile recordings. Early camera phones had limited storage, so most 3G2 clips are well under this limit. Longer recordings can be split before conversion if needed.

The output maintains your source resolution. We do not artificially upscale as this adds file size without real quality improvement. A 352x288 3G2 file becomes a 352x288 MTS file with H.264 compression, preserving the original detail level.
