TextDuratifier is an After Effects script that automatically sets the duration of text layers based on their content and the viewer’s reading speed, eliminating manual timing adjustments.
Developed by Artem Artemenko.
About TextDuratifier
TextDuratifier calculates the length of time each text layer should appear in After Effects by analyzing the layer’s content and applying a reading‑speed model. The script can also sequentially arrange layers on the timeline and generate an adaptive background with a configurable corner radius. Version 1.1.0 updated the speed‑calculation defaults, refreshed the color‑picker UI, and added persistence of script settings across After Effects restarts. Compatibility spans After Effects CS3 through the 2025 release, allowing use in both legacy and current projects. A demo video is hosted on the developer’s page.
