为什么要转换
Why convert M2TS to MP4
02
Acceptance by downstream tools
MP4 is the format most receiving systems expect for this kind of content. Converting upstream avoids the rejection and silent re-encoding that often happen when M2TS reaches an unprepared pipeline.
03
Lower storage and bandwidth cost
MP4 files are typically smaller than their M2TS counterparts, which reduces hosting, transfer, and storage costs at scale. The savings compound when serving the same content to many recipients.
