Tero Subtitler is an open source, cross-platform, and free subtitle editing software.

← Audio and video
Tero Subtitler: free subtitle editor. Edit, translate, and sync video subtitles on your desktop.

In simple English

Tero Subtitler helps you create and fix subtitle files for videos. You can watch your video, check the audio waveform, and adjust the exact timing of every line. It also connects to artificial intelligence tools to transcribe speech automatically. The software is free to download and use on your computer. It costs you nothing in money, but takes time to learn if you are new to video editing.

What it is

This repository contains the source code and release links for Tero Subtitler, an open-source subtitle editor built on the Lazarus IDE (a visual programming environment for the Pascal language). It replaces older subtitling tools from the same developer and integrates external helper programs like MPV (a command-line media player) and FFmpeg (a command-line tool for converting audio and video formats) to handle playback and media processing.

What it is good for

Solo creators, translators, and video editors who need a desktop program to sync subtitles, translate dialogue, or turn audio into text without paying for a commercial subscription.
