Part 1. MP4 or 3G2: What's the Best Video Format?
Should we convert MP4 to 3G2? When deciding between MP4 and 3G2, the best format largely depends on your use case.
MP4 (MPEG-4 Part 14) is a modern, versatile video format widely supported by nearly all devices and platforms. It provides high-quality video and audio, excellent compression efficiency, and compatibility with streaming, editing, and playback tools. MP4 supports advanced codecs like H.264 and H.265, making it ideal for everything from smartphones to 4K TVs.
On the other hand, 3G2 (3GPP2) is a specialized format developed for mobile devices, particularly older 3G phones. It uses less storage and bandwidth, making it suitable for low-powered devices or networks with limited speed. However, 3G2 lacks the flexibility and visual quality of MP4, and its compatibility with modern devices is very limited.
In general, MP4 is the superior choice for most users due to its balance of quality, efficiency, and universal support. Use 3G2 only when required for compatibility with legacy mobile systems or if you're optimizing for minimal file size and low bandwidth use.
