Features

📋

Import Dive Logs

Import Subsurface (XML/SSRF), UDDF, and FIT dive logs — straight from Garmin and Suunto dive computers — with full support for recreational, technical, and CCR dives with multi-tank pressure tracking.

🎨

Template Editor

One canvas, two views: arrange, resize and align cells in Edit mode, check the exact export pixels in Render mode. Independent label/value colors, text shadows, per-cell overrides, full undo/redo — save and share your designs as .utp templates.

📹

Graphical Video Sync

Play your footage in-app and align it with your dive visually — the timeline cursor follows the video. Save per-camera profiles so future dives sync automatically.

🌊

Dive Profile Graphic

Generate a customizable depth-over-time profile with a moving position indicator, optional deco-zone shading and grid — exportable as its own overlay, and themeable in one click from your template's color scheme.

📊

Interactive Timeline

Scrub through your dive and zoom into sections of interest — the visible range can be exported on its own.

✨

23 Bundled Templates

Classic dive-computer faces plus the new HUD, Social and Broadcast families — sci-fi HUDs, compact vertical-video widgets for Shorts/TikTok/Reels, and a broadcast lower third, each in two color variations.

📦

Flexible Export

Export transparent PNG sequences or encode directly to video (H.264, ProRes, VP9, HEVC) via FFmpeg.

💻

Cross-Platform

Available for Windows, macOS, and Linux (Flatpak). Built with Qt 6 for a native experience on every platform.

Getting Started

1

Import your dive log

Import your dive from Subsurface (.ssrf / .xml), any app that exports UDDF (.uddf), or straight from your Garmin or Suunto dive computer (.fit).

2

Customize your overlay

Pick one of the 23 bundled templates or create your own. Drag and resize cells, change fonts, colors and shadows, then check the exact result in Render mode.

3

Import your video

Load your footage and align it on the Video Preview tab — the timeline cursor follows the video, so you just match it to your dive computer.

4

Export

Export as a transparent image sequence for your editor, or encode directly to video with FFmpeg.
