Every time I create a video recording and go to save it, the file name 'Video' is shown and I have to change it manually. If I want to do more than one screen capture, I have to rename it manually so that the files don't overwrite. Is it possible to capture multiple times without renaming the files manually?

Hello!
I am interested in purchasing a screen recording solution. After doing some research I found My Screen Recorder Pro. I've read through the description and would like to receive some additional information. I have some questions:
-Is it possible to provide the application with the call to start a recording along with the file name?
-What does hidden mode mean?
Thank you in advance!
