WHY CONVERT
Why convert DFF to M2TS
02
Acceptance by downstream tools
M2TS 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 DFF reaches an unprepared pipeline.
03
Portable, predictable file format
M2TS 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.
