DiveCut - Freediver Editor

About

DiveCut is the video editor built for freedivers. Pick your dive footage, drop in your dive-computer FIT log, and DiveCut produces a cinematically color-graded clip with a synced depth-gauge HUD — in under a minute. DEPTH GAUGE HUD A center-pinned tape with cosine-faded ticks, a red current-depth marker, and a bold yellow depth readout — the look of a real dive computer, baked into your video. A vertical-rate indicator flags your descent and ascent speed, turning amber the moment you ascend too fast. SYNCED FROM YOUR DIVE COMPUTER Import a FIT file from any compatible dive computer — Garmin Descent, Suunto D5/D6, Shearwater, Apple Watch with Oceanic+. DiveCut parses depth, heart rate, and temperature, then aligns it to your video with a single "Sync dive start here" tap at the moment you broke the surface. Frame-step nudge lets you fine-tune the alignment. UNDERWATER COLOR A curated LUT pack tuned for the red-channel loss that ruins underwater footage at depth. Tropical Reef Shallow, Tropical Reef 10m, Deep Blue, and Kelp Forest. Custom .cube import is supported for your own looks. An intensity slider lets you blend any LUT to taste. MANUAL COLOR CONTROLS Eight sliders — Exposure, Contrast, Highlights, Shadows, Saturation, Vibrance, Temperature, Tint — for fine-tuning on top of the LUT. An auto white balance toggle compensates for the blue/green underwater cast. INFO BAR Optional info bar overlays Dive Time (since descent start), Max Depth (running maximum), Heart Rate, and Temperature — each shown only when your FIT log carries it — in a clean dive-computer aesthetic. An optional dive-profile graph plots your full descent alongside the footage. ON-DEVICE, NO ACCOUNT Everything runs on your iPhone. No login, no upload, no cloud round-trip. Your footage and dive logs stay on your device. The only network traffic is the App Store handling your purchase. EXPORT Save your finished video back to Photos in source resolution, 4K, 1080p, or 720p. Choose H.264 (compatibility) or HEVC (smaller files). Background-friendly export so you can leave the screen and come back when it's done. NOT A GENERAL VIDEO EDITOR DiveCut is opinionated. It does one thing — make your dive footage look great with a real dive HUD — and tries to do it in under a minute. If you want a multi-clip timeline, audio editing, or vector scopes, you want a different tool.
