A marker on a board
The recipe is built around a physical whiteboard, not a digital animation: a hand writes your heading in black marker, sketches the diagram in red and adds your labels.

Generate and check
The price in credits is shown on the button before you generate. Seedance 2.0 renders a 15-second vertical video at 720p. Check the lettering and the facts before you share it.
A fixed teaching sequence
The 15 seconds follow one order: heading, diagram, labels, takeaway, then a hold on the finished board.
Voiceover or marker sounds
Add a script for an English voiceover that reads it once, or leave narration empty for marker squeaks and room sound with no speech.

- Check spelling and facts in the finished video before you share it.
Questions & answers
What is the Whiteboard Explainer?

How long is the video and what format is it?
15 seconds, vertical 9:16, at 720p. These settings are fixed for this tool.

No. It is the style reference the tool uses for the look of the board, the hand and the markers. Your video is drawn from a blank board with your own topic.
Will the writing always be spelled correctly?
Not always. AI video can misspell words, so keep board text short and check the lettering and the facts in the finished video before you share it.
