About this application

Aegisub is a specialized desktop application designed for creating and modifying subtitles, running natively on Linux systems. It provides a visual timing interface that aligns text dialogue directly with audio waveforms and video frames. Users can set start and end timestamps, adjust positioning, and apply typesetting instructions to individual lines of text. The program includes automated styling tools and a built-in scripting engine to assist with complex subtitle formats and translations. Its layout centers around text grid editing combined with real-time video previewing to ensure synchronization.
