AI Avatar Welcome Video for New Dental Patients: Script and Cost

A dental practice can send new patients a short welcome video from a reusable avatar host: who they will meet, where to park, what to bring. With Sume Avatar 1.0 that is a scripted render of 4 to 60 seconds, not a live chat, so the script is where the work is.

Prices are from Sume's API pricing page and the request shape from Generate avatar video, both read on 2026-10-05. The avatar must exist first: Create new avatar accepts a prompt, a profile or a photo.

What should the script and scenes look like?

Three scenes keep a first-visit clip tidy: greeting, what to bring, and a reassurance beat. Sume estimates a spoken scene at ceil(words / 2.8) seconds, so the counts below are the planning numbers, not a measured render time.

The seconds column is Sume's planning estimate of ceil(words / 2.8) per scene, not a measured render time.

What does it cost?

The plan above comes to 18 seconds, inside the 4 to 60 second window. At Sume's per-second rates (no product image), one render costs $3.31 on standard, $4.41 on plus (the default when quality is omitted) and $9.90 on max. Across 40 patient intake emails, that is $132.48, $176.40 and $396.00. Creating the avatar is a separate one-time $0.95; later clips reuse the handle.

How do you keep a health-adjacent script safe?

Keep the avatar to logistics. Parking, forms and arrival time are things a script can state exactly; clinical advice is not. Write each fact into the script yourself and review the rendered clip before it goes out.

Render one clip first. Avatar video previews produce a still of the first frame, so you can check framing and the avatar's look before paying for the full video.

What will it not do?

It will not answer a patient's questions. The clip is the same for everyone who receives it, and Sume does not claim real-time conversation. If a patient needs to ask something, link them to your phone line or booking page.

Scripts for Avatar Video should be English; Sume's guidance is that non-English speech breaks caption alignment.
