Tracking explosive lifts (Advanced camera mode)

Within Metric, certain explosive movements may benefit from specialized camera settings available in Mode 2 or mode 3 - learn how to use them here.

Understanding Metric's camera modes

Metric's patented computer vision system accurately tracks barbell movement using just your smartphone's camera. While the standard tracking mode (Mode 1) works excellently for most lifts, certain explosive movements may benefit from specialized camera settings for optimal tracking accuracy.

Camera modes overview

You'll find the camera mode options in the controls stack on the recording screen. While Mode 1 is the default setting, Modes 2 and 3 are available for specific lifting scenarios.

When to use mode 2 & mode 3

Advanced camera modes (Mode 2 and 3) are specifically designed for explosive lifting where barbell mean velocity exceeds 1.25m/s or peak velocity exceeds 1.8m/s. This typically includes movements like:

  • Snatches
  • Power cleans
  • Loaded jumps
  • Light load, high-velocity sets

These modes reduce motion blur in your video, providing Metric with a sharper image for tracking fast-moving barbells. However, this comes with an important trade-off: advanced modes don't perform well in low-light conditions.

Requirements for switching modes

Before switching to an advanced mode, ensure your training environment meets these criteria:

  1. Well-lit environment (daylight or bright gym lighting)
  2. Movement velocity exceeding 1.25m/s mean or 1.8m/s peak

If unsure, start with Mode 1 and review your footage. When playing back the video frame by frame, significant blur of the barbell and plates indicates that switching to an advanced mode might be beneficial.

Mode 2 vs Mode 3

Both Mode 2 and 3 provide identical motion blur reduction and will improve tracking accuracy for fast movements in good lighting. The key difference lies in their compatibility with artificial lighting:

  • Mode 2 may introduce a flicker or strobing effect under certain artificial lighting conditions
  • Mode 3 was developed to eliminate this strobing effect
  • If you experience flickering in Mode 2, switch to Mode 3

Remember, Mode 1 is the most versatile and robust setting, suitable for most lifting scenarios including Olympic lifts and explosive movements below 1.25m/s mean velocity. Advanced modes should only be used when specific velocity and lighting conditions are met.
