Main status bar

The main Status bar contains messages about what is going on in QTM, e.g. when QTM is capturing or processing data. There can also be status messages for the real time processing and the camera synchronization.

It also shows the latency and the different frequencies during real-time and when capturing a measurement. The frequencies are updated continuously so that if the computer cannot process the data fast enough the frequencies will decrease. Next to the frequencies is a symbol that shows the status of the calibration, see chapter Introduction to calibration.

  • Time code

    Displays current value of incoming time code (SMPTE, IRIG, Camera time).

  • Latency

    The current real-time latency. Only displayed if enabled on the GUI page in the Project options dialog. For more information see chapter Real time latency.

  • GUI

    This is the update frequency of the QTM GUI. It can be changed on the GUI page in the Project options dialog.

  • RT

    This is how fast the data is processed by QTM in real-time. The frequency is set on the Camera system page in the Project options dialog or for a measurement in the Start capture dialog.
    The RT frequency can be lower than the camera frequency in two cases. First in RT/preview and Capture mode if the camera frequency is too high so that the computer cannot process all of the data. The second case is during a measurement in capture mode if Reduced real time frequency is selected.

    During real-time QTM can display a text with a warning in the main status bar, if not all frames are received from cameras (dropped frames) or if some cameras are lagging behind (frame mismatch). Both of these problems are caused by a too fast real-time frequency for what you are measuring on.

  • This is how fast the data is captured by the cameras. In RT/preview mode the frequency depends on the Real time frequency setting on the Camera system page in the Project options dialog. When Reduced real time frequency is selected the frequency will be displayed as reduced in RT in the status bar. During a measurement the displayed frequency is always the same Marker capture frequency.

    When external timebase is used EXT will be displayed in front of the frequency.
