Hi F.L.T. Amalthea
Thank you for downloading trakAxPc Pro.
The Grab and Vertical sliders allows you to change and move the image in the Trakkutter. If you want to restore the image/video to its original size click on the RESTORE IMAGE TO ORIGINAL DEFAULT STATE BUTTON. You may need to resize your screen to see it.( see screenshot)
If you want to change the grab icon to another function like Zoom just right click in the image window and select zoom in/out
I have also included a video to explain the functions of the trakkutter and the trakkutter window in regards to video being placed in it. You can access it at the following link.
http://www.youtube.com/watch?v=sZl9SQgtGHA - the explaintion of the trakkutter window starts at 3.34.
I hope this helps and if you have any questions, please do not hesitate to contact me.
Best regards
Cormac
