Chain Continuity & Multi-Master Keyframe Coverage- Two Methods For Edit-Ready Ai Filmmaking, John Trevino

Theatre Faculty Publications

Current AI video models generate short clips with inconsistent visual details across shots, preventing traditional film editing. A character may change clothing, lighting may shift, and spatial relationships may drift between angles—all of which break cinematic continuity (Bordwell, Thompson, & Smith, 2020). This paper formalizes Chain Continuity, a reproducible four-step method that eliminates these discontinuities by separating camera construction from performance generation. The method requires locking a single Master Key Frame taken from the first frame of the Master Shot, building all other camera angles as static Setup Frames derived only from that first-frame key, and then generating performances solely …

Rethinking Wireless Microphone Fidelity: Evidence, Outcomes, And Implications, John Trevino

Theatre Faculty Publications

This paper challenges long-standing assumptions about tradeo↵s between duplexing and microphone fidelity in consumer wireless audio systems. Through controlled experiments and comparative evaluations on modern consumer hardware, we demonstrate that (1) measurable improvements in recorded microphone fidelity are achievable in real-world scenarios previously considered infeasible, (2) objective metrics show statistically significant gains under the tested configurations, and (3) these gains enable practical workflows for field production and archival capture. For reasons of responsible disclosure and ongoing intellectual property protection, implementation details are withheld; instead we report experimental design at a high level, evaluation methodology, numeric results, and implications for practitioners …

Bluetooth Microphone Audio Activation, John Trevino

Theatre Faculty Publications

Bluetooth technology enables reliable wireless microphone activation for hands- free applications across a variety of industries. This paper surveys key considerations and general trends impacting audio activation, user experience, and ongoing improvements in wireless communication. No specific technical approach, implementation, or proprietary process is discussed.

Security And Reliability Considerations In Modern Bluetooth Audio Implementations, John Trevino

Theatre Faculty Publications

This paper provides a practical overview of security and reliability considerations relevant to modern Bluetooth audio implementations. Drawing from platform documentation and observed behavior in consumer devices, the report focuses on profile-level characteristics, common architectural constraints, and real-world reliability factors that affect both communication and media playback scenarios. The goal is to offer a clear, outcomes-oriented summary suitable for practitioners, educators, and technical evaluators. No proprietary techniques or implementation-specific methods are discussed.

High-Fidelity Wireless Mobile Audio In Film Production Engineering Practices And On-Set Workflow Design, John Trevino

Theatre Faculty Publications

Film production environments demand predictable, stable, and high-fidelity audio capture. Traditional approaches rely on dedicated hardware recorders, wired lavalier systems, and separate RF microphone setups. However, the rapid improvement of mobile processors and modern Bluetooth audio systems has opened new opportunities for filmmakers seeking compact recording workflows.

This paper examines the engineering and production techniques developed in 2025 while building mobile recording systems capable of delivering consistent, clean audio for filmmaking. The analysis focuses on system design, workflow ergonomics, and reliability under field conditions.

Cross-Platform Sample-Rate Behavior In Mobile Bluetooth Microphones A Comparative Audio-Production Study Of Android And Ios Systems, John Trevino

Theatre Faculty Publications

Bluetooth microphones—especially AirPods and similar wearables—are now used in mobile filmmaking for portable, actor-mounted voice capture. However, sample-rate behavior varies significantly across Android and iOS ecosystems. This paper analyzes cross-platform sample-rate performance using perceptual, non-mechanistic evaluation. The focus is on expressive clarity, tonal identity, continuity across recordings, and film-production workflow reliability under Bluetooth microphone conditions.

Cinematic Dialogue Capture With Mobile Wireless Microphones: A Systems Approach To Blocking, Acoustics, And Set Dynamics, John Trevino

Theatre Faculty Publications

This paper presents a systems-engineering analysis of cinematic dialogue capture using mobile wireless microphones. Building on field observations and workstation-based evaluation conducted between June and August 2025, the study models the acoustic, timing, and blocking interactions that shape production-sound outcomes on narrative film sets. A multi-layer framework is proposed that integrates sound recording, cinematography, actor movement, and post-production requirements. Results indicate that mobile microphone systems, when operated within disciplined workflows, can deliver high-quality dialogue coverage with notable advantages in mobility, scene flexibility, and production efficiency.

Stability Cues And User Interpretation In Mobile Bluetooth Recording Workflows, John Trevino

Theatre Faculty Publications

Mobile Bluetooth recording has become a practical tool for filmmakers, content creators, educators, and journalists. While technical specifications offer clear limits to wireless audio, perceived performance is often shaped more strongly by user interpretation, interface cues, and workflow stability. This paper analyzes the perceptual systems users rely on when operating Bluetooth microphones through mobile applications, focusing on stability cues, sonic anchors, and behavioral patterns that influence recorded outcomes. The goal is to establish an academic framework for understanding perceived wireless performance without discussing internal engineering mechanics.
