| For Stretch video cards of standard compression (h264) the frame rate that is displayed on Monitor in Intellect™ software can be less than the frame rate that is indicated by the video card manufacturer. This is due to the fact that while displaying the frame rate of video signal digitization on Monitor in Intellect™ software blank frames that are distributed by the video card, are not taken into account. «Blanck frames» do not contain the information about the image and are created by the video capture card when there are no changes in the video stream and a new video frame is the same as the previous one (for example, there is no motion in the frame). |

grooming
By default INTELLECT™ software digitizes video signals with the frame rate lower than maximum allowed one. This is caused by the following:
...
By default the total frame rate of video signals, which are digitized and processed by the same ADC, is 2 times lower than the maximum allowed one. This ratio is provided by frame scalinggrooming, which allows every second frame to be processed by the program.
Settings allow reducing (total frame rate increases) or increasing (total frame rate decreases) the scalinggrooming.
Frame scaling grooming is changed separately and independently for every ADC.
...
- Go to the Hardware tab in the System settings dialog box (1).
- Select the relevant Video Capture Device object, created before, in the Hardware tab in the objects tree (2). The settings panel for the selected object is displayed in the right part of the Hardware tab.
- If it is necessary to increase the total frame rate up to the maximum allowed value, move the Rate slider to the Max position (3).
- If it is necessary to reduce the total frame rate to the minimum allowed value, move the Rate slider to the Min position. The minimum total frame rate of video signals, digitized and processed by selected ADC, is 3 times lower than the maximum allowed one.
- If it is necessary to return the default scaling grooming settings, move the Rate slider to the middle position. The default total frame rate is 2 times lower than the maximum allowed one.
- Click the Apply button (4).
- Close the System settings dialog box and restart INTELLECT™ software.
