Getting Started
How to use Taawn during the beta: record with the right GoPro settings, mount your camera, cut and upload videos in the Android app, and set up camera calibration for 3D features.
What is Taawn?
Taawn is an alpha/beta training-assistance app for mountain bikers and trail riders. Compare runs on the same segment, study lines, and review timing — it is not turn-by-turn navigation and not a substitute for safety equipment or trail judgment.
How do I get started?
1. Install the Taawn Android app. 2. Add an activity (import or record a GPX track). 3. Create a segment for a section of that activity and upload a reference video. 4. Ride the segment again and upload run videos to compare. Video upload and processing happen in the mobile app — the website is for browsing and your profile.
Required beta settings (GoPro)
For the beta, use these settings on every recording (segment video and all run videos on that segment): • Camera: GoPro Hero 9–13 • Resolution: 1080p • Frame rate: 25 FPS • Field of view: Wide (not Ultra Wide — artificial stretch is unsupported in this beta) • Stabilization: Normal (not HyperSmooth Ultra or maximum EIS) Other combinations are not supported right now. Keep settings identical between your segment video and every run on that segment.
How should I mount the camera?
Mount the GoPro securely on your chest or handlebar so the trail ahead is visible. Avoid large obstructions in frame (hands, bags, mud guards). Keep the lens clean before you ride. A stable mount with a consistent angle helps matching and 3D alignment.
How do I cut and upload videos?
Use the Taawn Android app — there is no separate video editor. Create a segment: 1. Open your activity and start Create Segment. 2. Pick your GoPro video. 3. Set start and end on the GPX map. 4. Mark start frame, optional section frames, and end frame in the video player. 5. Name the segment and upload. Upload a run: 1. Open the segment and choose Upload Run. 2. Select your run video (same GoPro settings as the segment). 3. The app extracts metadata, downsamples if needed, and uploads in the background. Videos over 100 MB may need trimming or shorter clips before upload.
Consistency checklist
Before every recording, confirm: ✓ Same camera model ✓ 1080p · 25 FPS · Wide FOV · Normal stabilization ✓ Same settings for segment video and all runs on that segment ✓ Similar lighting and trail conditions when possible ✓ Lens clean, no large obstructions in frame
Do I need camera calibration?
Yes, for 3D reconstruction and trajectory overlays. All GoPro models currently require a calibration JSON file in the app — automatic import from newer GoPro metadata (Hero 12/13) is coming but not active yet. 1. In the app: You → My Cameras → add your GoPro model. 2. Tap Load calibration JSON and select the file for your model. 3. Assign that camera when creating a segment or uploading a run. Where to get the file: contact support through the app and we will provide a calibration file for your camera model during the beta. An automated calibration workflow is planned for later.
Recording conditions & disclaimer
Taawn works best in dry conditions with a clean lens. Heavy rain, mud splatter, or a very dirty lens often break video matching and 3D alignment. This is alpha/beta software — results are not guaranteed. Always ride within your limits; Taawn does not replace helmets, trail knowledge, or local rules.
What happens after upload?
Your video is preprocessed on the device (metadata extraction, downsampling), then uploaded. Server-side processing on GPU can take several minutes depending on queue and video length. You can check progress under You → Current upload jobs. 3D segment reconstruction and run alignment are optional and require a calibrated camera. Ghost Rider and timing comparisons work once basic processing completes.
Troubleshooting
“You need to add a camera with calibration data first” → You → My Cameras: register your GoPro and load calibration JSON. “Please assign a camera with calibration data to this segment” → Edit the segment or camera assignment and select your calibrated camera. “Camera calibration not found” → Open Garage, verify JSON is loaded, then retry 3D features. Upload fails or stalls → Check connection, file size (100 MB limit), and that the video is 1080p at 25 FPS Wide FOV.
FAQ
GPX and video: your activity GPX helps place segment start/end; GoPro GPMF sensor data (Hero 5+) improves sync when available. Upload limit: videos are downsampled on-device (longest side 640 px) before upload; very large source files may still hit the 100 MB cap. Web vs app: browse segments and runs on the website; record, cut, and upload only in the Android app.
