Inquiry about commercial use of videos generated via Google Labs Flow (Free tier) for a contest

Hello,I am planning to participate in a video contest using videos generated through the free credits of Google Labs Flow (Veo model).I will keep the official “Made with Veo” visible watermark on the video without any modification or removal.

  1. Does using the free tier/credits of Google Labs Flow for a contest entry violate the Google Terms of Service?

  2. Is it legally permitted to use the outputs for a commercial contest under the current preview terms?

I would highly appreciate your official confirmation to prevent any future copyright or terms violation issues. Thank you!
