What is 3G2?

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

What is MPG?

MPEG-1 System Stream (MPG) is a legacy video format used for Video CD and early digital video distribution.

When Should You Use 3G2 vs MPG?

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 MPG When...

Reach for MPG when your priority is vcd video, legacy multimedia, mpeg-1 playback — its efficient compression makes sharing fast and storage minimal.

3G2 vs MPG: Key Differences

  • •3G2 uses lossy compression while MPG uses lossy compression — both take the same approach to file size management.
  • •Both formats share lossy compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •Transparency: N/A
  • •File sizes: 3G2 files typically range Small, optimized for mobile and MPG files Smaller compared to uncompressed video.
  • •3G2 is optimized for legacy mobile video, mms messages while MPG is designed for vcd video, legacy multimedia, mpeg-1 playback — choose based on your specific workflow needs

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.
