How to record a math tutorial on a whiteboard
To record a math tutorial, write each step on the Excalicast whiteboard while you narrate the reasoning; it captures the operation stream and your voice and exports a clean MP4 in any aspect ratio, so the equations stay crisp and you can publish both a 16:9 lesson and a 9:16 Short.
Steps
- 1
Write the problem
Start with the problem statement on the canvas so viewers have context before you solve it.
- 2
Solve step by step, narrating
Work through each step while explaining out loud. The operation stream keeps handwriting crisp at any zoom.
- 3
Export for your platform
Export 16:9 for YouTube and 9:16 for Shorts/TikTok from the same recording — one solve, multiple posts.
FAQ
Will my handwriting stay readable in the video?
Yes. Because Excalicast re-renders frames from the operation stream rather than capturing screen pixels, handwriting and equations stay crisp at the exported resolution.
