SublerCLI for Mac

Command-line subtitle manager for macOS

SublerCLI is a free utility built for macOS users who prefer working from the terminal. It provides a compact, script-friendly way to handle subtitle tracks within video files — including extracting, inserting, and converting subtitle data — and serves as a non-graphical counterpart to GUI subtitle tools for workflows that favor speed and automation.

Key capabilities

• Rapid batch processing and easy integration into shell scripts or automated pipelines
• Pull subtitle tracks out of media containers (extract)
• Inject subtitle streams into video files (embed)
• Convert between common subtitle formats (for example: SRT, WebVTT, SSA)

Benefits and typical use cases

SublerCLI speeds repetitive tasks and fits naturally into video production or post-production toolchains. Because it runs in the terminal, it’s useful for:

• Automating repetitive subtitle jobs across many files
• Combining subtitle tasks with other command-line utilities (ffmpeg, bash scripts, CI systems)
• Handling subtitle maintenance for editors, localizers, and media teams who need consistent, repeatable processing

Quick-start recommendations

• Convert files to the desired subtitle format first, then validate timing and encoding
• Embed subtitles into the target container only after confirming track language and flags
• When extracting, save each track with a clear filename that includes language and format
• Use scripting to run batch operations and add logging for reproducibility

Compatibility, cost, and alternatives

SublerCLI supports multiple subtitle formats and works directly with many common video containers, making it suitable for a wide range of editing and delivery scenarios. The tool is free to use. If you prefer a visual interface, graphical subtitle managers remain available as alternative options.
