What is 3G2?

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

What is IVF?

AV1 IVF, raw AV1 codec bitstream container for testing and encoding — stored as video/ivf — uses lossy encoding to handle av1 codec development, video encoding benchmarks, raw bitstream analysis. Typical file sizes: varies by content.

When Should You Use 3G2 vs IVF?

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 IVF When...

Reach for IVF when your priority is av1 codec development, video encoding benchmarks, raw bitstream analysis — its efficient compression makes sharing fast and storage minimal.

3G2 vs IVF: Key Differences

  • •3G2 and IVF 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.
  • •How transparency is handled: IVF does not support alpha channels — transparent areas in the source will become opaque.
  • •File sizes: 3G2 files typically range Small, optimized for mobile and IVF files N/A.
  • •Use case fit: 3G2 targets legacy mobile video, mms messages and IVF targets av1 codec development, video encoding benchmarks, raw bitstream analysis — your choice depends on which workflow stage you are serving.

Advantages of 3G2

  • ✓The lossy nature of 3G2 means file sizes stay reasonable while handling Legacy mobile video, MMS messages efficiently.
  • ✓From mobile devices to enterprise servers, 3G2 is recognized and supported everywhere.
  • ✓Storage and bandwidth costs drop significantly when using 3G2 thanks to its efficient compression.
  • ✓3G2 is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Best Practices for 3G2 to IVF Conversion

  • →For 3G2 to IVF: encode at the target platform's native resolution — upscaling or downscaling adds unnecessary artifacts
  • →Test a short clip before converting the entire 3G2 file — this confirms IVF settings produce acceptable quality
  • →IVF is widely supported but choose bitrate carefully to balance quality and file size
  • →Use constant bitrate (CBR) for streaming delivery and variable bitrate (VBR) for archival storage
  • →Keep the original file in case you need to re-encode with different settings
  • →Check audio sync after conversion — container changes can sometimes cause drift

Troubleshooting 3G2 to IVF Conversion

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