About 3G2 to MP4 (H.265)
将 3G2 转换为 MP4 (H.265)。3G2 是 3GPP2 手机容器，用于 CDMA 时代的手机。 MP4（H.265）存放 HEVC 视频，比特率约为 H.264 的一半。 HEVC 解码需要更新的硬件，编码也更慢。。
Why convert 3G2 to MP4 (H.265)?
- 采用 MP4 (H.265) 的 lossy 压缩，文件更小。
- 在支持的情况下保留 动画和透明度。
- Private, no upload - runs in your browser.

When not to convert 3G2 to MP4 (H.265)
- Skip MP4 (H.265) for archival masters: lossy compression discards detail, so keep the 3G2 original.
- Keep a master copy: repeated exports stack small losses, so archive 3G2 before batch MP4 (H.265) shares.
Limits
Starting point: 3G2 - 3G2 is the 3GPP2 phone container used on CDMA-era handsets. EVRC audio tracks may need resampling for modern players. HEVC decoding needs newer hardware and encodes more slowly. Encode MP4 (H.265) (H.265 / AAC) from 3G2 at a bitrate near the source, and confirm the audio track before converting.
