I've shared some of my LoRA Pilot work here. This is my other project, Forma, for the days you want to generate an image or animate a still without setting up a workflow.
You choose a model, write a prompt and see the price before generating. Text to image, image editing and image to video are in the same studio. No subscription; you top up a balance when you need it. Your library is private by default, with no public feed.
For a short ad, I'd start with a few stills, choose the composition, then animate that one. Saves paying for video attempts while you're still deciding what the shot should look like.
I built it with occasional creators in mind. It's a generation tool, so you'll still want an editor for cuts, titles and sound.
