The Size of the Video Preview Has Changed – How Do I Restore It?

If you and your colleagues use the same user account, it’s possible that one of the following settings has been changed. Follow the steps below to identify and correct the issue.

1. Binning:

• Location: Found in the Device Controls when using the Video Preview.
• Explanation: Binning combines 2 or more camera pixels. If the same area of your sample is visible but the image size has changed, the binning level may have been altered.
• Solution: Ensure you are using the same binning level as before. Increasing the binning level will reduce the size of the Video Preview.

2. Crop Video:

• Location: Found in the Video menu under Crop Video.
• Explanation: Cropping reduces the video size to a specific region of the CCD. Smaller crop sizes will reduce the Video Preview size.
• Solution:
  • To undo the crop, select Full Frame in the Crop Video options.
  • Alternatively, select the Crop Tool, then click anywhere outside the crop boundary to restore the full frame.

3. CCD Active Area:

• Location: Found in the Video menu under CCD Active Area.
• Explanation: Margins may have been set by another user, reducing the overall image size. The CCD Active Area feature excludes unwanted regions of the field of view.
• Solution:
  • Open the CCD Active Area window.
  • Click the Default button to reset all margins to 0.

By following these steps, you can restore the Video Preview to its original size.
