12 common whiteboard video mistakes (and how to fix each one)

Hand-drawing videos look simple, but small details separate an amateur result from a professional one. We gathered the 12 most common whiteboard video mistakes — in the drawing, the settings, the script and the recording — and how to fix each one in Editor de Vídeo Online.

Drawing mistakes

1. Lines that are too light

Light-gray lines or faint pencil are not detected properly, and parts of the drawing go missing.

Fix: ink the lines in black, increase image contrast or raise the stroke sensitivity.

2. Shading and fine textures

Hatching and textures turn into hundreds of tiny strokes, and the hand looks like it is "scribbling noise".

Fix: use clean line art. If the drawing is AI-generated, ask for "no shading". See how to prepare a sketch.

3. A dirty background

Stains, paper folds and the phone's shadow get drawn.

Fix: scan with a document app or lighten the background; lower the sensitivity; or pick another background from the gallery — only the line moves onto the new paper.

4. Using a photo instead of a drawing

Photos have color variation everywhere; the effect gets messy.

Fix: for photos, use the Paper effect and Vox collage. For the drawn look, generate a line-art version.

Settings mistakes

5. Pencil tip marked wrong

The line comes out of the middle of the fingers or beside the pen.

Fix: click exactly on the pencil tip in the hand thumbnail. See how to set up the hand.

6. A disproportionate hand

A giant hand covering the drawing, or a tiny toy-like one.

Fix: adjust hand size (up to 400%) by comparing the tip with the line thickness.

7. Black lines on a dark background

On a chalkboard or dark background, the drawing disappears.

Fix: use Stroke color: White (chalk).

Script and pacing mistakes

8. Everything in one scene

A huge drawing with all the content takes forever to draw and wears viewers out.

Fix: one idea per scene; join the scenes in the Studio (see how).

9. Pace out of sync with narration

The drawing shows step 3 while the voice is still on step 1.

Fix: record narration first and adjust each scene's pace to follow it.

10. Too much text in the drawing

Handwritten paragraphs are slow to draw and hard to read.

Fix: use large keywords; leave the full text to narration or captions.

Recording and publishing mistakes

11. Switching tabs while recording

Recording is real-time; with the tab hidden or the computer overloaded, the video may drop frames.

Fix: keep the tab open and visible and close heavy programs. See performance tips.

12. Wrong format for the platform

A landscape video on Reels looks small with bars.

Fix: create the sketch in the final format (9:16 for Reels, TikTok and Shorts). See social media video formats.

Pre-recording checklist

Frequently asked questions

Why are parts of my drawing missing?

Usually the line is too light for the current sensitivity. Raise the sensitivity or darken the lines.

Why is dirt being drawn?

Sensitivity is too high for the image background. Lower it or clean the background first.

How do I make the video look professional?

A clean drawing, a well-configured hand, short scenes, clear narration and the right format. The rest is consistency.

Conclusion

Almost every whiteboard video mistake is solved before recording: in the drawing and three settings. Use the checklist and your next video will turn out much better. Open Editor de Vídeo Online and try it.
