As a YouTube creator, I wanted a faster way to create subtitles that match the duration of my videos. So I decided to build SubtitleToMP4. The idea is simple: if your audio has a relatively consistent reading speed, you can adjust the text timing to match the total duration of your video. When the timing is right, the subtitles can appear to be read naturally and almost in sync with the narration. SubtitleToMP4 automatically calculates the reading time from your text, lets you adjust the pace by ±50%, and provides a live preview before exporting. The result is a Full HD 1920×1080 MP4 with a green-screen background, so you can easily add the subtitles to your video using Clipchamp, CapCut, Premiere Pro, DaVinci Resolve, or other video editing software. It supports 76 languages and is designed as a simple, free Windows tool — no Python installation required.
