# Charmbracelet VHS Best Practices

Comprehensive best practices guide for VHS terminal recordings, maintained by Charmbracelet. Contains 47 rules across 8 categories, prioritized by impact to guide creation of professional, portable, and optimized terminal demos.

## When to Apply

Reference these guidelines when:
- Writing new VHS tape files
- Creating terminal demos for documentation
- Setting up CI/CD for automated GIF generation
- Optimizing recording file size and quality
- Troubleshooting tape file issues
- Reviewing tape files for best practices

## Rule Categories by Priority

| Priority | Category | Impact | Prefix |
|----------|----------|--------|--------|
| 1 | Configuration Structure | CRITICAL | `config-` |
| 2 | Dependency Management | CRITICAL | `deps-` |
| 3 | Command Syntax | HIGH | `cmd-` |
| 4 | Timing & Synchronization | HIGH | `timing-` |
| 5 | Output Optimization | MEDIUM-HIGH | `output-` |
| 6 | Visual Quality | MEDIUM | `visual-` |
| 7 | CI/Automation | MEDIUM | `ci-` |
| 8 | Advanced Patterns | LOW | `advanced-` |

## Quick Reference

### 1. Configuration Structure (CRITICAL)

- [`config-settings-order`](references/config-settings-order.md) - Place all settings before commands
- [`config-output-first`](references/config-output-first.md) - Declare output at file start
- [`config-shell-explicit`](references/config-shell-explicit.md) - Explicitly set shell type
- [`config-typing-speed-global`](references/config-typing-speed-global.md) - Set global TypingSpeed early
- [`config-dimensions-explicit`](references/config-dimensions-explicit.md) - Set explicit terminal dimensions
- [`config-comments-document`](references/config-comments-document.md) - Use comments to document tape structure

### 2. Dependency Management (CRITICAL)

- [`deps-require-early`](references/deps-require-early.md) - Use Require for dependency validation
- [`deps-require-order`](references/deps-require-order.md) - Place Require before settings
- [`deps-require-all`](references/deps-require-all.md) - Require all external commands
- [`deps-system-requirements`](references/deps-system-requirements.md) - Verify system dependencies

### 3. Command Syntax (HIGH)

- [`cmd-type-syntax`](references/cmd-type-syntax.md) - Use correct Type command syntax
- [`cmd-enter-explicit`](references/cmd-enter-explicit.md) - Always follow Type with Enter
- [`cmd-key-repeat`](references/cmd-key-repeat.md) - Use key repeat counts
- [`cmd-ctrl-combinations`](references/cmd-ctrl-combinations.md) - Use Ctrl combinations for terminal control
- [`cmd-hide-show`](references/cmd-hide-show.md) - Use Hide/Show for sensitive operations
- [`cmd-env-variables`](references/cmd-env-variables.md) - Use Env for environment variables
- [`cmd-screenshot`](references/cmd-screenshot.md) - Use Screenshot for static captures
- [`cmd-multiline-type`](references/cmd-multiline-type.md) - Handle multiline commands properly

### 4. Timing & Synchronization (HIGH)

- [`timing-sleep-after-enter`](references/timing-sleep-after-enter.md) - Add Sleep after commands for output
- [`timing-wait-pattern`](references/timing-wait-pattern.md) - Use Wait for dynamic command completion
- [`timing-type-speed-override`](references/timing-type-speed-override.md) - Override TypingSpeed for emphasis
- [`timing-sleep-units`](references/timing-sleep-units.md) - Use explicit time units
- [`timing-final-sleep`](references/timing-final-sleep.md) - End recordings with final Sleep
- [`timing-natural-pauses`](references/timing-natural-pauses.md) - Add natural pauses between actions
- [`timing-wait-timeout`](references/timing-wait-timeout.md) - Set appropriate Wait timeouts
- [`timing-playback-speed`](references/timing-playback-speed.md) - Use PlaybackSpeed for final adjustments

### 5. Output Optimization (MEDIUM-HIGH)

- [`output-format-selection`](references/output-format-selection.md) - Choose output format based on use case
- [`output-framerate`](references/output-framerate.md) - Optimize framerate for file size
- [`output-dimensions-optimize`](references/output-dimensions-optimize.md) - Right-size terminal dimensions

- [`output-multiple-formats`](references/output-multiple-formats.md) - Generate multiple output formats
- [`output-relative-paths`](references/output-relative-paths.md) - Use relative paths for portability

### 6. Visual Quality (MEDIUM)
