Welcome to the FROG Scan Help page where we have some FROG Scan hardware and software tips, suggestions, and a few things that we forgot to include in the manual (Gasp!).

Installing and Running VideoFROGscan under Vista

VideoFROGscan runs fine under Vista provided you do two things.  First, when you install VideoFROGscan, keep the install program from autostarting.  Right click on setup.exe and select “Run as Administrator.”  VideoFROG will then be able to make all the changes it needs to make to run on your computer.  The second, is when you run VideoFROG, select “Run as Administrator.”  You may edit the shortcut to do this for you.

 

Saving data in VideoFROG.

VideoFROG has several methods for saving data, which can be divided up into three different basic types: 1) Raw bitmap image, 2) processed data, and 3) semi-processed data for other applications.

Bitmap images of the raw video can be saved by left clicking in the raw video image. No dialog box will appear. The data will be saved with a date and time stamp. We feel that this allows several files to be saved in fairly rapid succession.

Processed data can be saved in both VideoFROG mode and Spatial Profile mode. In fact, when in VideoFROG mode, you can ONLY save processed data. In Spatial Profile mode you can save both processed data, and semi-processed data.

The semi-processed data I’m referring to is the image save when in Spatial Profiling mode. Suppose you want to save a FROG trace for Femtosoft’s FROG program. Clicking on the “Save Image” button save the image, with the background subtracted, in an ASCII file. Use this data saving feature to save data for other programs. The processed data is mainly for plotting programs and spread sheet programs.
