Speedometer video recording, replay, and data overlays
🚧 This page is a work in progress — more details and images are being added.
Speedometer can work as a location-aware dash cam or action camera. A recording keeps the clean original video together with the location and motion data needed for replay, subtitles, photo and waypoint creation, and optional stamped exports.
The data overlays do not have to be permanently burned into the original. During replay or export, you can use the layout saved when the video was recorded, apply your current layout, or view the video with no overlays.
Open the Video camera
Open MENU > VIDEO. Speedometer opens its camera in Video mode.
Before recording, frame the view, select the front or back camera if needed,
check the microphone indicator, and open Settings if you want to change
recording or overlay options.

Viewfinder controls
The central shutter button starts and stops recording. While recording, its appearance changes and the elapsed recording time is shown beside the viewfinder controls.
The Photo/Video control switches capture mode. During a video recording, use the separate camera button to take a location-aware photo without stopping the video.
The microphone control shows whether audio is available and, when enabled in Video settings, displays a live audio level:
- a live level confirms that the microphone is receiving sound;
- tap the microphone to mute or unmute recording audio;
- the mute choice is remembered for the next recording;
- if microphone permission is unavailable, video can still be recorded without audio.
When Loop recording is enabled, a badge shows the retained Loop duration.
The navigation-bar controls provide:
Videosfor the saved recording library;- camera selection for the front, back, or another available camera;
Notesfor the Video title, note, tags, and address;Settingsfor Video recording, overlays, file naming, and related camera options.
Record a normal video
Tap the shutter button once to start. Confirm that the duration is advancing and that the microphone state is what you expect. Tap the shutter again to stop.

The saved video appears in MENU > VIDEOS. A recording can briefly show as Processing
while the app prepares it for replay and makes its recorded data
self-contained. You can start another recording when the camera becomes ready;
you do not need to keep the Videos list open while preparation finishes.
The recording remains useful if preparation is interrupted. The app keeps the playable original and its recoverable data rather than discarding the whole recording.
Take a photo while recording
Tap the small camera button in Video mode to take a still photo while video recording continues.
The photo uses the location and camera state from the moment you tapped the button. It follows the normal photo save and waypoint workflow and does not replace or split the active video.
Loop recording
Loop recording continuously keeps only the latest configured duration. Older completed parts are removed while recording, and tapping Stop saves the retained window as one video.
This is useful when the important event may happen after a long uneventful period: you can keep a recent window without saving one indefinitely growing file.
Loop recording works only while the camera remains visible. Closing the camera or moving the app to the background stops and saves the retained recording.
To configure it, open Settings > Video settings, turn on Loop recording, and
choose:
Keep latest— the duration retained when you stop;Loop stabilization—Responsive,Auto, orOff.
Responsive is the recommended starting point for an accurately bounded
rolling window. Auto can provide more smoothing but may take longer to finish
after Stop. Use Off only with a stable tripod, gimbal, vehicle mount, or for
troubleshooting.
Video settings
Open the camera, tap Settings, then choose Video settings.

Recording
Video quality controls the capture resolution used for new recordings.
Notify when recording stops unexpectedly can add a system notification after
the app saves a video stopped by an interruption. The app also shows an in-app
message when possible. Pressing Stop normally does not send a notification.
Loop recording and its retained duration and stabilization are also configured in this section.
Audio
Microphone sets whether new recordings start with audio On or Muted. You can
still change the microphone from the viewfinder.
Audio level before recording opens the microphone while you are framing and
shows its live level. Turn it off if you do not want the microphone opened until
recording starts.
Stabilization
Standard is the recommended normal-recording setting. It balances stable
video with responsive starting and stopping.
Auto allows iOS to choose stronger stabilization. It can crop more of the
frame and may take longer to finish after Stop.
Use Off for a stable tripod, gimbal, vehicle mount, or troubleshooting.

Overlays
Video overlays opens the layout editor for the data and identity panels used
during live Video mode, replay, and stamped export.
Export
Include subtitles adds an SRT file containing time, location, altitude,
heading, and related recorded telemetry.
Subtitle units chooses between the app’s currently selected units and fixed
metric values suitable for editing tools.
Export quality offers:
Sourceto stay close to the recorded video quality;Smaller fileto use stronger compression for sharing.
Keep audio in exports controls whether exported videos contain sound. With
Source quality and audio kept, a full Original export can share the stored MOV
directly when no additional metadata preparation is needed.
Build the Video overlay layout
Open Settings > Video settings > Video overlays.

The top of the screen is a preview of the camera canvas. Tap an enabled overlay to select it, or drag it toward another corner. The highlighted corner shows where it will snap.
The controls below the preview let you:
- add a hidden overlay;
- hide the selected overlay;
- make a scalable overlay smaller or larger;
- rotate overlays that support horizontal and vertical layouts;
- configure overlay-specific content or behavior;
- move overlapping overlays toward the edge or inward in their corner stack.
The original video stays clean. This layout is saved as the recording’s Historical overlay recipe and can be changed later without rewriting the original.
Watermark
Add a company name, personal identity, vehicle, equipment label, or logo. Watermark content is shared where appropriate, while the Video layout controls its visibility, placement, size, and appearance for video.
QR Code
The QR Code can encode selected recording fields. It can turn a stamped video frame into a map or navigation link for the location represented by that frame.
The QR footprint is fixed to preserve scan reliability.
Map
The live Map overlay follows your current position and can show the trail recorded since the video started. Saved-video replay and stamped export use the recorded route data.
Map options include type, day/night appearance, zoom, orientation indicators, and optional speed-adaptive live zoom.
Speed
The Speed overlay shows the recorded speed in the app’s selected units and tracks the maximum reached so far. If a usable location fix is not available, the live value is shown as unavailable rather than inventing a speed.
Pitch & Roll
Pitch & Roll shows vehicle or device angle during the recording. Choose Ground for gravity-based angles or Relative when the current orientation should become the local zero.
The selected reference and recorded motion data are preserved so Historical replay and stamped export reproduce the recording rather than recalculating it from today’s position.
G-Cross
G-Cross visualizes lateral and longitudinal acceleration, calibration state,
and directional peaks. Its live CLEAR PEAKS action affects the recorded peak
history; replay and export reproduce the resulting history but do not expose
the live command.
Find saved recordings
Open Videos from the camera or MENU > VIDEOS.

Each ready row shows its thumbnail, title, note or location summary, recording date, duration, file size, and the overlays saved with the recording.
Use search to find text in titles, notes, tags, addresses, dates, coordinates, and other video fields. The date filter can limit the list to recent recordings or a selected month or year.
Tap a ready row to replay it. A row marked Processing becomes playable automatically when preparation finishes.
Replay and create a photo and waypoint

For fine positioning, swipe left or right directly across the video; drag upward while swiping to slow the movement.
Pause replay or scrub the timeline to any moment, then tap the camera button to create a normal Photo and waypoint from that exact video frame. The app:
- extracts the correctly oriented frame;
- uses the replay moment’s timestamp, location, heading, and resolved address;
- stores that frame address as
Manual, so it stays historical and is not replaced by later reverse geocoding; - follows your existing Photo capture preference:
Savecreates the Photo immediately,Previewopens the normal Photo preview, and automatic Photo Notes can open Photo notes automatically.
The new Photo follows normal Photo-note rules. Title, Note, and Collection are not automatically copied from the recording-wide Video notes; add them directly, or use the Notes transfer tools when the Video already has useful context.
This is useful when you notice an important place, measurement, label, or detail only after the recording has finished.
Use video and photo notes together
Photo Notes and Video Notes now include a collapsible source section. In the Photo editor it shows Video notes; in the Video editor it shows Photo notes. A replay-derived Photo shows notes from its actual source video.
Apply Title, Note, Address, Folder field name, and Tags/Folder
individually, or use Apply all. Undo reverses the most recent individual
Apply, or the complete Apply-all operation.
Clear From: and To: labels explain transfers when fields are named
differently, for example From: Tags -> To: Collection. Resolution pills
show whether a value transfers as Auto, Manual, or Auto → Manual.
Automatic title patterns transfer when compatible; historical resolved
values, addresses, and tag/folder values transfer as Manual where needed.
Original, Stamped, and overlay history
The stamp button switches between the clean Original view and the last used
Stamped overlay view.
For detailed control, open More > Overlays:
Historicaluses the immutable layout and appearance saved when recording started;Currentuses today’s Video overlay settings with the data recorded in the video;Nonehides all replay overlays.
Changing replay overlays does not modify the stored Original or the Historical recipe.
Select and export a range
Open More > Select export range.

Move to the beginning of the useful clip and tap Set Start. Move forward and
tap Set End, then tap Done. The timeline shows the selected A–B interval.
Export then offers both:
Selected rangewith its start and end times;Full video.
Each scope offers:
Originalfor a clean video without visible overlays;Stampedusing the selected Historical, Current, or None overlay mode.
The selected range remains available while that replay screen is open, so you
can adjust it or export more than one version. Clear export range removes it.
Interruptions, storage, and privacy
Video recording is a foreground camera activity. Closing the camera, moving the app to the background, app termination, or a capture interruption stops the recording. The app saves the playable material completed up to the interruption.
Loop recording limits the retained time window, but it still needs working space while recording and assembling the final video. Check available device storage before a long session.
Original video and recorded telemetry stay on the device until you choose to share or export them. A stamped export is a new presentation file; it does not overwrite the clean Original.
Secure the iPhone in a suitable mount before driving or riding. Set framing, audio, stabilization, and overlays before moving, and do not operate camera controls while responsible for a vehicle.
Good first setup
- Open
Video settingsand start with Standard stabilization. - Confirm Video quality and microphone state.
- Turn on the pre-recording audio level and check that it responds.
- Add only the overlays you need and keep important parts of the camera view unobstructed.
- Make a short test recording.
- Open it in Videos, compare Original and Stamped, and test the timeline.
- Export a short range before depending on the setup for a long recording.
- Use Loop recording when the recent window matters more than keeping the whole session.
