  • Using the VIVE Mars CamTrack.

  • Completed lens calibration and tracking calibration using the camera calibrator.

  • In the tracking test, after setting the tracking delay to 1.85, placed markers 1 and 2 on each leg of a tripod and confirmed that it worked properly.

  • While testing by panning the camera left and right, a recurring patterned issue occurs where the floor appears to slip and then becomes stable again at 20-second intervals (stable for about 10 seconds, then slipping occurs every 20 seconds).

  • Genlock is set to 29.97 for both the capture card and VIVE Mars only.

  • The camera is a Sony A7S III.

    Genlock is supposed to be syncing the camera shutter to the same clock as the Vive Mars. Since your camera doesn’t have Genlock, there’s not point in adding Genlock downstream, since it doesn’t do anything to keep anything in sync.

    Hi,

    This issue typically happens when a system is not fully genlocked. The delay between the camera frames and the tracking data constantly changes
    In your case, it's your camera that is not genlocked.
    To achieve perfect sync, every component must be genlocked (camera, tracking system, capture card).

    Warmest regards,
