Separate browsing from rendering
A site may let you upload or preview files for free and charge only when generating. Other sites may require payment before accepting a task. Check whether the advertised free action produces a downloadable personalized video, an example, a draft or a watermarked demonstration.
Credits only make sense beside a per-video rate
A pack containing 100 credits says little without the charge per generation. Compare duration, resolution, output count, retries and expiry together. Do not assume a larger number of credits gives better value across different sites. For this preview, each local job uses 2 demo credits.
What a test checkout means here
The preview includes a clearly marked mock checkout to validate orders and account balances. It does not collect a real payment. Production pricing depends on measured generation cost, successful delivery, storage and payment fees. We have not measured those costs for a verified NEON dance output yet.
Check failure and refund terms separately
A failed task may release reserved credits without refunding an earlier credit-pack purchase. Ask what happens when a request is delayed, when output quality is disappointing and when a completed file cannot be saved. Retrying an unknown request can duplicate a paid job; return to its existing status page first.
