Sessions and Analysis

Recordings are raw telemetry captures. Sessions organize one or more recordings and add notes, tags, metadata, and analysis.

Recordings​

Open Replay to:

  • record live telemetry
  • save the rolling live buffer
  • import or export .dfrec files
  • replay with the parser stored in the recording
  • rename, annotate, delete, or share a recording

The recording library displays cached metadata immediately and refreshes file metadata in the background. An existing list remains visible during refresh.

If a recording is linked to one or more sessions, the session count is clickable. Open it to see exactly where the recording is used before deleting or moving it.

Sessions Recordings Library

Create a Session​

  1. Open Sessions.
  2. Create a new session.
  3. Add a name, date, notes, tags, and optional metadata.
  4. Link one or more recordings.
  5. Save the session.

Linked recordings use relative references where possible, making session packages portable between devices.

Run Analysis​

Select Analyze or Reanalyze on a session. DashForge shows a progress state while it decodes recordings and builds the result.

The analysis can include:

  • track trace and bounds
  • driving sections
  • speed and input samples
  • braking and lockup events
  • drift, traction, and stability events
  • severity, timestamp, speed, throttle, brake, and contextual advice

Results are cached inside the .dfsession document. Reopening an unchanged session does not need to recompute the full analysis.

Inspect Events​

  • Filter events by type or severity.
  • Sort the event list.
  • Select a marker on the trace to see its detail.
  • Select an event in the list to locate it on the trace.
  • Reanalyze after changing linked recordings.

Live Trace​

The Live Trace dashboard widget uses the same analysis model while telemetry is active. It can:

  • draw the driven path
  • place event markers
  • automatically open new event details
  • close details after a configurable delay
  • speak event names

Live analysis runs only while a consuming widget is visible.

Moving Sessions Between Devices​

Exporting or peer-sharing a session creates a package containing the session and its available linked recordings. The receiver confirms before download, sees import progress, and gets an automatic library refresh after import.
