Data-driven text, graphics, and ticks can use one or more telemetry streams to control what the graphic renders onto the canvas each frame. Mapping controls determine which stream supplies a value and how that value is converted or scaled.
Map a stream
- Load a GoPro video into Studio, and select or create a new template.
- Add or select a "data·text", "data·graphic", or "data·ticks" layer in the template.
- In its data or input section, choose "Stream".
- Select a compatible telemetry stream.
- Choose a unit conversion if the source unit is not the display unit you need.
- Choose a range mapping when the graphic input expects a normalized or fixed range.
- Preview several points in the timeline before saving.
The stream list shows only data present in the loaded source. An existing selection may be marked unavailable when the current source lacks it.
Mapping methods
- "fit data min/max" maps the minimum and maximum values in the relevant range to the output range.
- "fit max absolute" uses a symmetric scale around zero, which is useful for signed G-force or acceleration.
- "fixed range" uses explicit input and output limits.
- A unit converter changes compatible measurements such as m/s to mph, or meters to feet.
Automatic min/max mapping can change the apparent scale when you change the timeline range.
Use visibility rules only when a layer should appear for a data condition. Test values around each threshold so the layer does not flicker unexpectedly.
