WHY CONVERT
Why convert NUT to M4V
02
Acceptance by downstream tools
M4V 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 NUT reaches an unprepared pipeline.
03
Lower storage and bandwidth cost
M4V files are typically smaller than their NUT counterparts, which reduces hosting, transfer, and storage costs at scale. The savings compound when serving the same content to many recipients.
