Testing a small tool that turns sketches into short AI videos

I recently launched a small tool called SketchVideo AI.

The idea is simple:

Upload a sketch → choose a video style → describe the motion → generate a short video

It is not meant to be a complex video editor or a professional animation tool. The goal is much smaller: help people turn rough sketches, drawings, storyboards, or concept images into quick motion previews.

Why I made it

I noticed that many AI video tools work better when the input is already a polished image. But many early ideas are not polished images — they are just rough sketches.

For example:

a character sketch
a children’s drawing
a product concept
a storyboard frame
an architecture or interior sketch

Instead of asking users to write complex prompts, I wanted to make the workflow more direct.

The current workflow

The tool currently works like this:

Upload a sketch or drawing
Choose a video style
Describe the motion
Generate a short AI video

There are three video styles:

Sketch Animation — keeps the hand-drawn look
Illustration Video — turns the sketch into a polished illustrated video
Realistic Video — converts the sketch into a more realistic/cinematic video

The motion prompt is intentionally simple. For example:

The rabbit walks forward, its ears bounce gently, and the camera slowly zooms in.
What I’m trying to validate

This is a small SEO-focused tool, so I’m not trying to build a huge platform right away.

The main things I want to validate are:

Do people actually want to turn sketches into videos?
Which use case is strongest: characters, kids’ drawings, product sketches, storyboards, or architecture?
Are users willing to pay for video credits after trying a few examples?
Is “sketch → image → video” a better workflow than direct sketch-to-video?

So far, I feel the most promising use cases are:

character sketches
children’s drawings
product concept videos
storyboard motion previews
What I’m keeping simple

I’m intentionally avoiding too many advanced controls for now.

No complex timeline.
No professional video editor.
No model selection exposed to users.
No complicated prompt system.

Just:

Sketch + Style + Motion = Video
Looking for feedback

I’d love to hear what you think:

Which use case sounds most valuable?
Would you use this for creative work, product concepts, or just fun?
Should the product focus more on illustration-style videos or realistic videos?
Would a credit-based pricing model make sense for this kind of tool?
