Click the corresponding icon on the toolbar or select Video from the Capture menu.
Sequence capture
Click the corresponding icon on the toolbar. A dialog window will appear where you can
set a number of parameters for sequence capture. Click the Photo radio button to set
the time to begin capturing images, interval between them and the total number of
images. Click the Video radio button to set the time to begin recording videos, their

Calibrating
Before calibrating the microscope, turn the grid display on. To do so, select on from
Options > Crossing. By default, the grid is visible. Place the calibration scale on the
stage and focus your view. Make sure that the vertical axis of the grid is parallel to scale
divisions and capture an image. Double-click the image thumbnail to open it in a
separate window.
Click the corresponding icon on the toolbar to begin calibration. Using your mouse,
choose two points on the image (you have to know the actual distance between these
two points). Once you choose the second point, a dialog window will open, where you
have to enter the known distance in the Actual dimension field. The application will
automatically calculate the magnification of the image. Click OK to close the dialog
window. The calculated magnification will be displayed in the Magnification field.
Note: chosen points should form a horizontal line.
You can check calibration results by measuring the same distance with the Any Angle Line
tool. Click the measurements icon, choose the Any Angle Line tool and draw a similar line
on the image. If the measured distance is equal to the actual distance, calibration has been
successful.
Recalibration
The calibration process has to be repeated if the magnification or focus has been changed
during observations.
Click the corresponding icon on the toolbar again and select Reset picture magnification
from Reset magnification. Repeat the calibration process, as described above. Change the
magnification and capture a few images. Double-click one of the thumbnails to open the
resulting image in a preview window. Click the calibration icon on the toolbar and select Set
picture magnification from Set magnification. Enter the current magnification in the dialog
window that appears and click OK.
If you want to use the same magnification when capturing images in the future, click the
calibration icon on the toolbar and select Set capture magnification from Set
magnification.
Measurements
It is recommended to calibrate the system before proceeding with measurements.
Any Angle Line. Press and hold the left mouse button to start drawing a line. Release the left
mouse button to complete the line.
Continuous Line. Use this tool to draw a curve on the image and measure its length.
Radius Circle. Draw a straight line on the image. The application will automatically calculate
the radius, as well as circumference and area of the corresponding circle.
Diameter Circle. Draw a straight line on the image. The application will automatically
calculate the diameter, as well as circumference and area of the corresponding circle.
Three Points Angle. Place three points on the image with your mouse. The application will
automatically calculate the angle value.
Draw and text
PortableCapture Pro allows you to add drawings and textboxes to your images. Open an
image in a preview window and click the Pencil icon on the toolbar. Select one of the tools
from the drop-down menu and draw something on the image. By clicking the TT icon on the
toolbar, you can edit font type and color to be used in textboxes.
