Mitti

Mitti is a highly specialized and innovative software application engineered as a dedicated video cueing and playback utility for macOS.¹ Moving far beyond the static file organization and manual triggering of standard video players, Mitti is designed as a definitive, intelligent platform that provides seamless, high-performance control over media queues for live events, theater productions, and audiovisual installations. It represents the essential modern standard for VJs (Video Jockeys), lighting designers, stage managers, and producers who demand reliable, synchronized, and creatively flexible real-time video playback.

The Architecture of Live Performance

The core strength of Mitti lies in its focus on the dynamic, time-sensitive demands of a live environment, ensuring precision and stability under pressure:

• Cue-Based Workflow: Mitti organizes video files (or "cues") into a structured, editable playlist or sequence. Each cue can be assigned specific triggers, playback settings, and visual effects. This structure allows the operator to pre-program an entire show, ensuring the correct video plays at the correct moment with absolute reliability, replacing the stressful process of manually searching and launching files during a show.

• Precise Synchronization and Timing: The application is engineered for synchronization. It provides fine-grained control over the start, loop, and end points of every clip. Crucially, Mitti supports external control via ²$\text{MIDI}$ and $\text{OSC}$ (Open Sound Control) protocols. This allows a lighting console, a sound engineer's $\text{DAW}$, or a physical control surface to trigger video cues with micro-second accuracy, enabling tightly integrated audiovisual spectacles.

• Layering and Blending: Mitti is designed to handle multiple video streams simultaneously through layers. This allows the operator to composite effects, foreground graphics, and background video. It includes professional-grade blending modes and opacity controls, enabling smooth transitions and complex visual effects that can be adjusted in real-time without interrupting the main output.

Versatility and Output Control

Mitti is engineered for speed, high-resolution output, and seamless compatibility with professional display hardware:

• High-Performance Playback: The utility is optimized to leverage the Mac's dedicated graphics processing unit ($\text{GPU}$), allowing it to handle multiple $\text{HD}$ and even $4\text{K}$ video streams concurrently without dropping frames. This smooth, reliable playback is non-negotiable for live performances where any stutter or lag is instantly visible.

• Flexible Output Routing: The application offers robust control over where the video output is sent. Users can designate specific output ports or external displays, making it easy to route a feed to a projector, an ⁷$\text{LED}$ wall, or a video switcher. It also supports essential professional features like ⁹$\text{Syphon}$ and ¹⁰$\text{NDI}$ for sharing video streams across the network to other mapping or rendering software.

• Real-Time $\text{FX}$ and Correction: Mitti includes built-in tools for real-time manipulation, such as color correction, cropping, and geometric distortion tools. These features allow the operator to make on-the-fly adjustments to compensate for projector alignment issues or dynamically alter the visual mood of a scene using simple, low-latency effects.

Mitti is the essential modern tool for live video, providing an intelligent, synchronized, and indispensable platform that converts a potentially chaotic sequence of media files into a precisely timed, professionally controlled, and visually stunning performance.
