WHY CONVERT
01
Converting from ALAC to OGV aligns the file with the encoding choices the downstream pipeline expects. The result is a deliverable that fits naturally into the destination workflow.
02
OGV 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 ALAC reaches an unprepared pipeline.
03
OGV 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.
