A: Avatars
Limits on how many? No hard cap. You can create as many avatars as your credits allow. The only limit is credits: if you don’t have enough for a given generation, it just won’t run.

What can I do once created? Plenty — announcement videos, UGC-style content, and more. For each avatar you can apply speech, scenes, backgrounds, and subtitles, then generate.

Do they have to be photorealistic humans? Not at all. You can do realistic humans (using your own image or stock assets), but also animals, cartoons — whatever you want. Avatars can also speak in different languages.

More than one person in a video? Right now Studio is built for a single avatar per video, so a true two-person video isn’t fully smooth yet. The workflow you described is exactly the right workaround: create two separate avatars, generate individual clips, and stitch them together for a podcast/conversation feel. Native multi-avatar videos are something we’re looking at adding.

Typical workflow for reference: generate the avatar (with its voice and personality) → create a video for it → add the speech → add scenes and subtitles → generate.

Media credits
Media credits are the same currency across the board — they’re consumed for images, videos, avatars, and short virals alike. The difference isn’t the credit type, it’s model access. The other was limited to Wan 2 but strong with whitelabel in tier10
And 310 companies. With Studio, all models are unlocked, not just Wan 2 — that’s also a real upgrade.
