为什么要转换
Why convert AVI to OPUS
02
Acceptance by downstream tools
OPUS 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 AVI reaches an unprepared pipeline.
03
Lower storage and bandwidth cost
OPUS files are typically smaller than their AVI counterparts, which reduces hosting, transfer, and storage costs at scale. The savings compound when serving the same content to many recipients.
