RL model: Video not showing on the model card

Question on the model upload routine. I am trying to upload an RL model to the hub, using the downloaded and slightly adjusted collab notebook from unit 4 of the HF RL course. Everything uploads fine, except video snippet does not show up on the model card. Similar issue from previous upload attempt – instead of a video the browser only shows a black square. Anyone had a similar issue or can point to a relevant discussion?

As was advised on discord, I’ve added “reinforcement-learning” to tags in the readme file and it recognised the replay file.
