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.

What is 3G2?

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

When Should You Use IVF vs 3G2?

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.

Use 3G2 When...

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

IVF vs 3G2: Key Differences

  • •The core technical difference: IVF relies on lossy compression whereas 3G2 uses lossy compression.
  • •Neither format changes compression philosophy — both are lossy compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
  • •Transparency: N/A
  • •Storage footprint: varies for IVF vs Small, optimized for mobile for 3G2.
  • •Use case fit: IVF targets av1 codec development, video encoding benchmarks, raw bitstream analysis and 3G2 targets legacy mobile video, mms messages — your choice depends on which workflow stage you are serving.

Advantages of IVF

  • ✓The lossy nature of IVF means file sizes stay reasonable while handling AV1 codec development, video encoding benchmarks, raw bitstream analysis efficiently.
  • ✓From mobile devices to enterprise servers, IVF is recognized and supported everywhere.
  • ✓Storage and bandwidth costs drop significantly when using IVF thanks to its efficient compression.
  • ✓IVF is a first-class citizen in all major software ecosystems, from creative suites to development environments.

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 IVF to 3G2 Conversion

  • →For IVF to 3G2: encode at the target platform's native resolution — upscaling or downscaling adds unnecessary artifacts
  • →Test a short clip before converting the entire IVF file — this confirms 3G2 settings produce acceptable quality
  • →3G2 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 IVF to 3G2 Conversion

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