The operating principle of ImageGrab is as follows:
- You open a video file.
- You navigate to the desired position.
- You extract an image.
Optionally you can also embed (“inlay”) text in the video to be captured in the image, and of course define where, in what format, under what name etc … the images will be saved.
An intervalometer allows you to automatically capture all the images of the video according to a defined time interval.
