Betamax enables deterministic, repeatable terminal captures for documentation and demos by running commands in a controlled tmux environment and saving outputs as PNGs or GIFs.
Run betamax capture <command> to create a deterministic screenshot or demo.
High-intent search queries and answers about installing and using this skill.
Betamax captures terminal commands for documentation by running them in a controlled tmux session and saving outputs as deterministic PNG screenshots, ensuring reproducible visuals across different environments.
Yes, you can create animated GIF demos for CLI tool onboarding by recording command executions within a controlled tmux session, producing reproducible visual demonstrations that remain consistent across environments.
Yes, tmux must be installed to generate deterministic terminal captures. The tool relies on tmux to create a controlled session environment where commands execute and outputs are recorded reliably as images or GIFs.
You configure output directories and themes for terminal screenshots using per-project .betamaxrc files, global configurations, or named presets, which govern output locations, visual themes, and capture timing.
The best way to ensure reproducible terminal visuals across environments is to run commands in a controlled tmux session using deterministic capture presets, which standardize output formats and timing for documentation.
Terminal recordings may look different without deterministic capture. By running commands in a controlled tmux session with configured presets for timing and themes, you eliminate environmental variances and ensure identical output.
