FAQ
Why convert M4S to J2K?

This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to J2K removes layer support. Moving to J2K removes streaming delivery.
What should I review after converting M4S to J2K?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
