About Motion Subtitle Maker

Motion Subtitle Maker, developed by Xavier Lafontaine, automates the generation of animated subtitles from an SRT file within After Effects. It can render the subtitles to QuickTime video files or PNG image sequences. In addition to the rendered media, the script creates fcpxml and xml files that import the subtitles back into the timeline with frame‑accurate precision, and allows re‑export of compositions via those xml files without rebuilding from the original SRT. Template fonts are downloaded automatically from Adobe Fonts, and the interface is available in French. The script is compatible with After Effects versions 2022 through 2026. A demo video is provided on the developer’s page.
