Clinic waiting-room clip: 12 seconds of Wan 3.0 for 75 cents

A 12-second ambient clip for a clinic waiting-room screen costs $0.75 at 480p, $1.50 at 720p and $3.00 at 1080p on wan-3.0 through Sume. A screen on the wall is usually viewed from a distance, so 720p at $1.50 is plenty.

Use generated video for mood and motion only: calm interiors, abstract water or light, a stylized illustration of brushing. Do not use it for anything that states a medical fact.

Price

Wan 3.0 lists at $0.05, $0.10 and $0.20 per second; Sume bills list times 1.25 (video router docs). Twelve seconds divides cleanly, so none of these totals need rounding.

What to generate and what not to

Good prompts describe a scene: soft light across a clean treatment room, slow camera move, no people in focus. The facts, the instructions and the clinic's phone number belong in text you add with an editor or on the screen software, where you control the spelling.

Do not ask a video model to depict a procedure or show how a tool is used. It will invent plausible-looking but wrong details.

Making a loop

Waiting-room screens loop. Send a photo of your reception area as the first frame and the same photo as the last frame, so the clip ends where it began (video generation docs). Review the result for a visible jump at the seam before you put it on rotation.

Keep a person in the loop

In a regulated setting, a qualified staff member should approve each clip. Sume generates the video and reports the billed amount in usage.cost; it does not review health content for accuracy.

Practical notes

Keep the playlist short. Six clips of 12 seconds is about a minute and a quarter of looped content, which is plenty for a waiting room, and it costs $4.50 at 480p or $9.00 at 720p.

Consider accessibility as well: use captions, avoid fast flashing light, and keep contrast high so the screen is readable from across the room.
