It seems like external libraries might not be allowed, but there is a chance that I could use python-pptx in the python_user_visible environment, though I’m not sure. Alternatively, I could create an HTML skeleton for the user to download and use with a tool. Maybe a better approach would be to provide a CSV or JSON script with a timeline, text, and voice references, as many text-to-video platforms support imports in those formats. I’ll generate a CSV with this approach, allowing for easy importing.
