Why SteadyFlow?

Not Another Slideshow Maker

🎬 Music-Aware Intelligence

Most apps place images at fixed intervals. SteadyFlow listens to your music and places transitions on actual beats, downbeats, and song segments. 15 photos over a 2-minute song? The algorithm selects the 15 strongest musical moments automatically.

🧠 Per-Image AI Analysis

Every single image is analyzed: saliency detection finds the subject, horizon detection ensures level framing, aesthetic scoring identifies your best shots, and subject isolation creates depth masks for parallax effects.

✨ One-Click Cinema

No timeline. No keyframes. No manual adjustments. Drop your photos, pick a style card, and export. The AI Director handles pacing, transitions, color grading, and motion—all tuned to the emotional arc of your chosen music.

🔒 Truly Private

Everything runs 100% on-device. Your photos are analyzed by Apple's Vision framework and CoreML—never uploaded anywhere. No cloud. No subscriptions. No data leaves your Mac.

APPLE FOUNDATION MODELS • macOS 26+

Powered by Apple Intelligence

On macOS Tahoe and later, SteadyFlow harnesses Apple Foundation Models running entirely on your device. The on-device LLM analyzes your photo collection and intelligently directs the cinematic style—choosing pacing, transitions, and emotional tone based on what it sees in your images.

Zero-Edit Creation

Forget timelines and keyframes. SteadyFlow uses high-performance GPU acceleration for real-time color grading, depth synthesis, and motion blur rendering. The CPU is reserved strictly for the final video stitching, ensuring a fluid, edit-free experience that generates professional results automatically.

AI Behavioral Director

On macOS 26+, Apple Foundation Models analyze your photos and craft a cinematic vision—determining style, pacing, and emotional arc. The on-device LLM sees labels, aesthetics, and composition to direct your video like a real cinematographer. Efficient heuristic fallbacks ensure great results on earlier macOS versions too.

Adaptive Audio Sync

SteadyFlow doesn't just "detect beats." It intelligently switches between Energy Analysis (Peak-to-Average Power Ratio > 4.5 for drums) and Spectral Flux (for acoustic/classical) to ensure your cuts hit the musical transients exactly where they feel right.

AVDepthData + CIImage

Depth Synthesis

By extracting embedded depth maps from HEIC files or estimating them via ML, the engine separates foreground from background. This enables true 3D Parallax effects, adding a cinematic "dolly" motion to otherwise static images.

ColorGradingService.swift

Procedural 3D LUTs

Instead of static overlays, the color engine generates 3D Color Cubes procedurally directly in memory. Whether it's the teal-shadow push of "Teal & Orange" or the warmth of "Kodak Gold," grading is applied mathematically at the pixel level on the GPU.
