About
Ameko lets users create and edit Advanced Substation Alpha (ASS) subtitles while watching the associated video and refining dialogue timing. Developed by AmekoProject, it is an open-source System Tools program for Windows x64. Its Audio Visualizer displays timestamps, assigns subtitle timing with left- or right-clicks, and seeks through the video with a middle-click.
Timing defaults to Snap to Frame for frame-accurate placement, while Free Placement allows finer positioning; holding Shift temporarily switches modes, and settings can change the default. Subtitle creators can use the Subtitle Profiler to measure render time, image size, and image count for every event, a chosen time span, or selected events, then export the results to CSV.
The Scripting Playground exposes script source before installation and lets users inspect or edit scripts already installed, while the --safe launch option temporarily turns off script loading. A dedicated vertical-video layout, persistent window state across restarts, unmanaged-crash reporting, and Linux drag-and-drop support round out the workflow for subtitle editors, translators, and video creators.
Ameko requires Windows 10 or later or Windows Server 2016 or later on x64 hardware. Version 1.2.2 is a hotfix for a Windows 1.2.0 problem that caused a crash and restart when closing the program, and it also fixes crashes when opening one video while another was still opening. Additional corrections address the About box, command-line paths containing spaces, frame-seek calculations, and an intermittently closing Command Palette.
Requires Windows 10+ · Server 2016+ · Architecture: x64
