# Anthem — Submit Caption Corrections
#
# Double-click this after you have fixed captions in Premiere. It asks for the
# XML you exported from the caption nest and sends it to Anthem so future
# captions learn from your edits. It never touches your project.
#
# The editor never needs a job id: the exported sequence is still named
# "Anthem Captions <run>-<id>", and the server uses that to match the run.
#
# The engine address is baked at build time or overridden with ANTHEM_ENGINE_URL.
