Reveal slide lines in lesson videos as they are spoken

Videos created from your slide PDFs now reveal content line by line as the narration reaches each point. Rhythm strips also draw across the page in real time, helping students follow along naturally.

What’s changed

Lesson videos made from uploaded slide PDFs previously displayed each slide all at once. Now, slides build up line by line in sync with the narration, and rhythm strips draw smoothly from left to right.

Good to know

• If a slide page is not ready within 75 seconds, it appears whole rather than revealing line by line.
• Any line that cannot be cleanly covered remains visible on screen from the start.
• Works with standard PDF slides as well as image-only presentation exports.
• Re-rendering a video with the same slides and narration reuses saved timings without recalculating.
• Rhythm strips draw themselves on as they are spoken too.
