## One-line description

gpx2video is a native macOS app that converts GPX tracks to video — overlaying GPS tracks (GPX files) onto your videos in real time, adding a follow-mode map, a circular route thumbnail with progress trail, customizable speed / time / heart-rate widgets, and a full-activity heart-rate graph — then exports the result up to 4K with hardware-accelerated H.264.

## Three-line description

gpx2video is a Mac-native video overlay tool for cyclists, runners, motorcyclists, road-trippers, and outdoor creators. You drop in a video and a `.gpx` track from Garmin / Strava / Apple Fitness / Wahoo, customize the map widget, route thumbnail, speed and time widgets, then export up to 4K with VideoToolbox hardware encoding. Everything runs locally on Apple Silicon — no cloud upload, no Electron, no recurring server fees baked in.

## Long-form description

gpx2video solves a specific problem: you have a GoPro / Insta360 / phone clip from an activity, and a `.gpx` track recorded by your watch / bike computer / phone, and you want to combine them into a video that shows where you were, how fast, and at what time — without paying $300+ for a desktop telemetry suite, opening a subscription to a web service, or shipping your footage to a cloud render farm.

The app is built around several widgets you can drop onto the video and freely position:

1. **Real-time map overlay** — A live route-following map. Choose OpenStreetMap (free, no token) or Mapbox GL (Mapbox token required). Pick a circle or rounded-rectangle shape. Toggle north-up or follow mode (rotates so the direction of travel is always up). High-DPI @2x rendering. Adjustable opacity and border. Two border styles: a slim Default ring, or a GTA-style triple ring with a live compass badge that tracks north.

2. **GPS path thumbnail widget** — A standalone circular thumbnail showing the **entire** route at a glance, with a brighter "progress" trail revealing the portion already covered as the video plays. Optional map background. Optional elevation tinting (path color gradient by altitude). Draggable anywhere on the frame. Shares the map widget's border styles (slim Default or GTA-style triple ring with compass badge).

3. **Speed widget** — Current speed in km/h, mph, or m/s. Pick font, color, size, and position.

4. **Time widget** — Real-time timestamp from the GPX data. Same customization as the speed widget.

5. **Heart Rate widget** — Live BPM read from the GPX `gpxtpx:hr` extension (the de-facto standard exported by Garmin, Strava, Apple Fitness, Wahoo, and most modern training watches / chest straps). Optional heart icon. Optional second line showing cumulative min / max from the start of the activity up to the current playback position. Widget hides on frames where the GPX has no heart-rate sample, so videos from runs / rides where you forgot to wear the strap halfway just gracefully skip rendering.

6. **Heart Rate Graph widget** — The full-activity heart-rate curve drawn as a sparkline-style plot, with a live playhead cursor that follows the video. X-axis uses real GPX timestamps (uneven sampling is preserved, no fake interpolation); y-axis is the overall min/max BPM with a 5 BPM pad. Gaps in the curve where heart-rate data is missing are drawn as breaks, not bridged. Useful for showing the climb-vs-recovery story over a long ride / run in a single glance.

7. **Timeline editor** — Split, trim, and drag GPX segments to align the track timestamps with your video timecode. Useful when the GPS recording started a few seconds before or after the camera; or when stitching multiple GPX files; or when discarding paused / idle segments.

Every widget can be toggled in the settings panel, or managed right in the preview: click a widget to select it (a highlight ring appears), press Delete to hide it, Cmd+Z to bring it back.

Beyond the widgets, gpx2video supports **multi-track import** (e.g. one GPX from your watch, another from a bike computer), a **frame-accurate live preview**, full **undo/redo**, **`.g2v` JSON project files** that round-trip cleanly (auto-save on quit, restore on next launch — FCPX-style), and an **async export queue** so you can keep editing while a render runs in the background. NTSC-accurate frame rate handling (23.976 / 29.97 / 59.94 fps included).

Export presets: **Original / 4K / 2K / 1080p / 720p**, encoded with **H.264 via VideoToolbox** (hardware encoder on Apple Silicon), AAC audio. No proprietary container — output is standard MP4.

**Bilingual UI** — English and Simplified Chinese, switchable from the menu without restart.

## Platform requirements

- **macOS 14.6 (Sonoma) or later** — uses modern SwiftUI APIs and AVFoundation features that earlier versions don't have
- **Apple Silicon only** (M1 / M2 / M3 / M4) — no Intel Mac build, intentionally. VideoToolbox H.264 + Metal map tile rendering are optimized for ARM
- Roughly **8 GB RAM** comfortable for 4K timelines; 4K export will use 16 GB+
- Internet only required for map tile downloads (cached aggressively) — editing and exporting are fully offline
- Self-distributed: signed with an Apple Developer ID and Apple-notarized, so it passes Gatekeeper without the "unidentified developer" warning. Not in the Mac App Store.

## How it compares to alternatives

- **Telemetry Overlay** (Marc Hertl, paid Mac/Win desktop) — closest competitor on Mac. Telemetry Overlay has broader format / sensor support (FIT, TCX, SRT, MP4 GPMF, DJI Goggles, BLE live sensors, power meters, cadence sensors) and a larger set of widget styles. gpx2video focuses on the GPX flow (including the GPX heart-rate extension that Garmin / Strava / Apple Fitness / Wahoo all export), and ships with a tighter native macOS UI, a lifetime / one-time-payment tier, and zero data egress (no telemetry / cloud component).
- **Dashware** (Windows-only, discontinued) — gpx2video is the macOS equivalent.
- **VIRB Edit** (Garmin, Windows-only, deprecated 2022) — gpx2video is a modern macOS replacement.
- **Strava in-app overlays / Relive** — Web-only auto-generated short clips, not full video editing.
- **Final Cut Pro plugins** ("MotionVFX mTracker GPS" etc.) — More expensive, requires FCP, doesn't import raw GPX.
- **Custom FFmpeg + ImageMagick scripts** — Possible but requires hours of scripting per video.

## Typical use cases

- **Cycling videos** — pair a GoPro chest mount with a bike computer GPX. Show speed, route, distance climbed, and a heart-rate curve to tell the climb-vs-recovery story.
- **Motorcycle / motovlog** — same as cycling but motovloggers want bigger speed numbers + a route thumbnail in the corner.
- **Running / trail running** — show pace, route thumbnail, and heart-rate widget (live BPM + cumulative max). Ultras and city long runs look great with the heart-rate graph showing pacing strategy across the activity.
- **Road trips** — slow-paced map overlay on highway scenery. Show city names by enabling Mapbox tiles.
- **Skiing / snowboarding** — drop into a follow-mode map; speed widget shows resort-relevant km/h.
- **Sailing / kayaking** — route thumbnail shows the path through open water where landmarks aren't obvious.
- **Paragliding / hang gliding** — elevation-tinted path is especially useful here.
- **Hiking / backpacking** — route thumbnail on summit reveal shots is a popular pattern.
- **Drone + activity** — overlay the GPS from your activity on drone footage shot of you doing it.

## Workflow

1. **Record**: capture video with any camera; capture GPX with any device (Garmin, Apple Watch, phone app).
2. **Optional preprocessing**: use the companion tool at https://tool.gpx2video.com to trim/merge/smooth/fix the GPX timestamps before import (browser-based, no upload).
3. **Import**: drag the `.mp4`/`.mov`/`.m4v` and `.gpx` files into gpx2video.
4. **Sync**: use the timeline to align GPX timestamps with video timecode.
5. **Style**: pick map provider, shape, theme. Drop in the widgets you want, drag to position.
6. **Preview**: scrub the timeline to confirm the result.
7. **Export**: pick a preset (Original / 4K / 2K / 1080p / 720p). Hardware-accelerated render runs in the background queue while you start editing the next project.

## Companion tool

**tool.gpx2video.com** — Free, browser-based GPX editor for prep work:
- Trim / cut / merge GPX files
- Smooth jittery GPS noise
- Fix wrong / missing timestamps
- Visualize multiple tracks on a map before importing
- Pure client-side (SvelteKit) — your files never leave the browser.

## Privacy

- Editing and export happen **entirely on your Mac**. We never see your video, GPX, or project files.
- The only data sent to our servers is: your email (during purchase) and a generated license key (so the app can verify you're a Pro user).
- No analytics, no fingerprinting, no third-party trackers on either the website or the app.
- Stripe handles payment processing. Resend sends the license email. Cloudflare Workers + KV host the license API. Mapbox / OpenStreetMap tiles are fetched directly from your Mac to their servers, not proxied through us.

## Frequently asked

**Q: Does it work on Intel Mac?**
No, Apple Silicon only. We use VideoToolbox + Metal in ways that aren't worth back-porting.

**Q: Is there a Windows / Linux version?**
No, macOS-only by design.

**Q: Can I import FIT or TCX files?**
Currently GPX only. Use the companion tool at tool.gpx2video.com to convert if your device exports FIT — or any open converter (e.g. https://gotoes.org).

**Q: Does it support heart-rate data?**
Yes — the Heart Rate widget reads BPM from the GPX `gpxtpx:hr` extension, which is what Garmin Connect, Strava, Apple Fitness, and Wahoo all write when exporting GPX from a workout. There is also a Heart Rate Graph widget that draws the full-activity BPM curve with a live cursor. If your GPX file has no heart-rate data, the widget hides on frames where the sample is missing — nothing crashes, the widget just gracefully skips rendering.

**Q: Does it support power meter / cadence / temperature?**
Not in v1.x — GPX rarely carries those fields. If you need power / cadence overlays, Telemetry Overlay reading the original FIT file is the right tool today.

**Q: Why isn't it on the Mac App Store?**
App Store sandboxing makes the multi-track timeline editor + project file workflow significantly worse, so we ship a notarized DMG directly. Same security level: Apple Developer ID + Apple notarized.

**Q: How do I update to a new version?**
The app checks `https://stripe.gpx2video.com/api/version` on launch and notifies you if a new version is out. Click the prompt to download the new DMG manually.

**Q: Can I get a refund?**
14-day window, both Pro Yearly and Pro Lifetime, no questions asked. Email ithinkerchan@gmail.com.

**Q: Where's the source?**
Closed source for the macOS app. Some surrounding infrastructure (Cloudflare worker, website) is publicly visible on the author's GitHub.

**Q: Is there a Sparkle-style in-app updater?**
No. Updates are surfaced as a notification with a link to the new DMG. The author chose self-hosted update notification over Sparkle's complexity for the current scale.
