Notes and quick guidance

• “Fixed-fee” can mean different things: per-piece set prices (e.g., $99/video), fixed-price packages (10 videos for $X), monthly subscription (flat monthly fee for a set number of collaborations), or ad-hoc fixed-price job posts on marketplaces. Check each provider’s licensing terms — usage rights (12‑month vs perpetual) often change the fixed price. (help.tribegroup.co)
• If you want, I can: narrow this to platforms that give perpetual commercial licences, filter by budget (e.g., under A$500 per video), or compare 2–3 platforms side-by-side (pricing + rights + turnaround). Which would help most?
