The automation can handle selection and upload, but it cannot validate timing, language, encoding, or whether the file matches the video.
Pair files clearly
Yes, for prepared subtitle files with predictable names and a stable upload interface.
Record one upload cycle
Number the video and subtitle pairs, use a dedicated folder, and record one upload-and-save-draft cycle in MacroLoop. Verify the selected filename on every test.
Preview before publishing
Preview captions before publication and keep language, accessibility, and rights decisions manual.
THE TAKEAWAY
Automate file handling only after subtitle quality and video matching are complete.
