Playback speed and speaking rate

Two different speed controls help you work precisely: the playback speed of the video, and the speaking rate of a line's audio. They do different things.

All of these features are part of the €12.99/month subscription.

Playback speed

The playback speed changes how fast the video plays back while you edit — handy for lining up a tricky passage or reviewing a fast exchange.

• The speed button on the rythmo band toolbar (shown as x1, x1.25, …) cycles through the available speeds each time you click it: 0.2, 0.5, 0.75, 1, 1.25, 1.5, 2.
• The same control is in the Timeline menu (Speed).

This only affects playback in the editor; it doesn't change your exported video.

Speaking rate (per line)

The speaking rate adjusts the pace of a line's audio — the generated AI voice or your recorded take — so it fits the line's duration.

• On a line in the script panel, a speed-rate slider runs from 0.8× to 4×.
• Raise it to fit more into a short line, lower it for a slower delivery.

Which one do I need?

• Reviewing or syncing the picture → playback speed (toolbar / Timeline menu).
• Making a voice fit its line → speaking rate (the per-line slider).
