Guide
One whiteboard idea, different platform frames
A whiteboard video that works on YouTube may not work on TikTok. YouTube usually rewards a wider 16:9 frame where viewers can follow the full structure of a lesson or product walkthrough. TikTok, Reels, and Shorts need 9:16 vertical video, where every label has to be large enough for a phone screen. RedNote-style posts often work well in a portrait-friendly 3:4 frame. Square 1:1 is useful when you want one clip that can travel across feeds without feeling too wide or too tall.
ExcaliRec lets you choose the aspect ratio before recording, so the whiteboard is framed for the destination from the start. You are not forced to record a wide desktop and crop it later. Pick 16:9 for YouTube, 9:16 for TikTok and Reels, 3:4 for RedNote-style explainers, or 1:1 for general social posts. Then draw inside that frame as if it were the final video.
Automatic zoom matters even more on mobile. A whiteboard can become dense quickly: small words, arrows, nested boxes, and diagrams that looked clear on your monitor can become unreadable on a phone. ExcaliRec can follow the active part of the drawing, so viewers see the current point without losing the feeling of a live explanation. That is why it works well for quick lessons, product breakdowns, founder notes, and short educational clips.
The optional webcam bubble helps when trust or teaching presence matters. The teleprompter helps you stay on track without turning the recording into a slide deck. When you stop recording, the file downloads locally as WebM. Before publishing, trim dead air, check that text is readable on a phone, add captions if your platform favors silent watching, and convert to MP4 only when your editor or upload workflow requires it.
