At the moment, the high-level gemini_model.generate_content method in the Vertex AI Python SDK doesn’t provide a built-in way to set fps metadata when using Part.from_uri(). However, the underlying Vertex API does support videoMetadata.fps if you construct the request manually or via the REST API. Until then, you'll need to choose between switching to a lower-level approach or waiting for a future SDK update. You can also submit a feature request to Google Cloud.
