为什么要转换
Why convert RM to F4V
02
Acceptance by downstream tools
F4V 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 RM reaches an unprepared pipeline.
03
Portable, predictable file format
F4V is well documented and decodable by long-lived tooling, which matters for archives, deliverables, and any file that needs to outlive the software that created it.
