VelocityCam

VelocityCam is a local-first telemetry video recorder and performance analytics application for Android. It captures camera footage synchronized with live GPS/GNSS speed, G-force, course, and distance data, allowing users to review sessions with interactive telemetry playback and export share-ready videos with customizable HUD overlays baked directly into the footage.

Designed for road and track driving, boat racing and marine testing, off-road trails, and motorcycles, VelocityCam works offline without requiring user accounts or cloud video uploads—keeping recorded videos and fine-grain session telemetry stored locally on the device. Users can record using internal phone GPS or pair external Bluetooth GNSS receivers (such as RaceBox) for higher-frequency telemetry.

Key Features:

• Synchronized Telemetry Video: Records video alongside GPS speed (MPH or KM/H), G-force, altitude, heading, and distance while keeping the original raw video untouched.
• Activity-Specific HUD Profiles: Includes Minimal HUD (free), plus Telemetry, Performance, and Boat Racing HUD profiles with customizable visual themes.
• Performance Analytics & Timing: Calculates GPS/GNSS-estimated acceleration and distance runs (such as 0-60 MPH, quarter-mile, and rolling-start marine presets like 8 MPH to 660 ft / 1000 ft) with run-to-run delta comparisons.
• Offline Route Trace: Renders a color-coded GPS Ghost Route or mini inset path without requiring cellular data or online map tiles.
• Multi-Format Export: Exports HUD-rendered videos in original, landscape, vertical, and square aspect ratios, alongside raw telemetry exports in CSV, GPX, and KML formats.
