What is 3G2?

3GPP2 (3G2) is a multimedia container format developed for CDMA mobile networks, supporting video and audio streaming.

What is HEVC?

Raw H.265/HEVC is an elementary stream of High Efficiency Video Coding data, doubling compression efficiency over H.264.

When Should You Use 3G2 vs HEVC?

Use 3G2 When...

Reach for 3G2 when your priority is legacy mobile video, mms messages — its efficient compression makes sharing fast and storage minimal.

Use HEVC When...

Reach for HEVC when your priority is high-efficiency video encoding, 4k/8k streams — its efficient compression makes sharing fast and storage minimal.

3G2 vs HEVC: Key Differences

  • •3G2 and HEVC diverge on compression: lossy compression for the source, lossy compression for the target.
  • •Both formats share lossy compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •Alpha channel support: HEVC lacks transparency support.
  • •Storage footprint: Small, optimized for mobile for 3G2 vs 50% smaller than H.264 at same quality for HEVC.
  • •3G2 is optimized for legacy mobile video, mms messages while HEVC is designed for high-efficiency video encoding, 4k/8k streams — choose based on your specific workflow needs

Advantages of 3G2

  • ✓At its core, 3G2 relies on lossy encoding — a design choice that makes it perfect for Legacy mobile video, MMS messages.
  • ✓You won't run into compatibility issues with 3G2 — it's a universal standard across platforms.
  • ✓File size management with 3G2: aggressive compression with minimal visible quality loss.
  • ✓Every major application in the Legacy mobile video, MMS messages space supports 3G2 natively.

Advantages of HEVC

  • ✓HEVC uses lossy compression tailored for High-efficiency video encoding, 4K/8K streams.
  • ✓HEVC is supported natively on virtually every device, browser, and operating system.
  • ✓HEVC files are compact and quick to transfer, even over slow connections.
  • ✓HEVC integrates seamlessly with all major creative tools and workflows.

Best Practices for 3G2 to HEVC Conversion

  • →Converting 3G2 to HEVC: match the output resolution and bitrate to your target platform's requirements
  • →HEVC offers efficient streaming-optimized compression — ideal for online delivery
  • →Use appropriate bitrate for the balance of quality and file size
  • →HEVC is a lossy format, so expect some quality loss at higher compression ratios
  • →Always keep a backup of your original files before converting
  • →Choose the appropriate quality settings for your specific use case

Troubleshooting 3G2 to HEVC Conversion

  • !HEVC won't play on target device → check codec compatibility (H.264 has broadest support)
  • !Audio out of sync after 3G2 to HEVC conversion → try re-muxing with a different container format
  • !HEVC quality is too low → increase the bitrate; for 1080p video, 8-15 Mbps is recommended
  • !File size increased converting 3G2 to HEVC → lossless or higher-bitrate outputs naturally produce larger files
