Intersense won’t lock to targets.

If you get the green crosses and white boxes in ISDemo, then getting it working in Previzion should be straightforward. Before you exit ISDemo32, are you selecting File->Save Current?

When running the Intersense inside Previzion, you need to have a stable Sync source – either the Airtrack plugged into an AJA GEN10, an Evertz 2530 DAC, or similar source of tri-level sync. The frame rate should be shown in the right side of the UI panel, as under the Sync Warning Lights.

When you start up the Intersense inside Previzion, it generates a sync function that genlocks the data from the Intersense. If you look at the sfServer startup sequenceand sfServer window, you should see a couple of things in the sfServer window:

  • Found Mutex Sync Object
  • Vertical Refresh Rate: 59.94 or 47.96
  • The bottom left number should be around 180 for 59.94 operation, or about 135-140 for 47.96 (23.98) operation.

Also, check to make sure that the Intersense ‘Pitch’ level is set inside Previzion correctly, by clicking the ‘Configure’ tab next to the Intersense dropdown in the Previzion UI . . the Previzion setting overrides the setting inside ISDemo32 when Previzion is started up.

Basically, if it locks to targets in ISDemo, it will work inside Previzion, so it’s probably one of the above settings.

Intersense stops responding.

  • Deselect Intersense from the Position and Rotation tracking menus.
  • Deselect Airtrack from the Rot Smoothing menu.
  • Power cycle the Intersense (unplug the larger 3 pin power connector from the mounting case, wait 10 seconds, and plug it back in.)
  • Reselect the Intersense from the Rotation tracking menu. Wait 5-10 seconds for the light to come on. The background should start moving around.
  • Reselect Intersense from the Position menu.
  • Reselect Airtrack from the Rot Smoothing menu.

Output HDSDI Video Stutters

If the output HDSDI video stutters after changing frame rates, power cycle the system, including removing the power cord for 10-20 seconds.

External LTC timecode not recognized.

  • Exit Previzion.
  • Start All Programs->Merlin->BRec1. Verify that there is a green bar 2/3 of the way up on the ‘Audio Level R1’ display. Click LTC on the top VTR timecode display to verify LTC timecode.
  • If timecode is not displayed, check connections according to timecode settings.
  • Power cycle AJA ADA4 converter.

No video

If live HDSDI video does not show up in Previzion when the Enable button is clicked:

  • Exit Previzion.
  • Start up All Programs->Merlin->BRec1. Video should display in preview window.
  • If video not present, power down system. Unplug system power cable and wait 10-20 seconds. Connect power cable and bring system back up. Retry BRec1.
