A video editor with raw footage in hand needs to turn it into a deliverable video version when a finished cut is due.
No existing alternative is mentioned; by common inference editors currently cut manually in professional editing software, but this is inference rather than a fact supported by the material.
The public material is a single positioning line; it does not say which editing step it replaces and gives no user complaints or legacy-workflow description, so the pain cannot be reconstructed from available facts.
