Need help saving images

[racast5]

I'm very new to programming and hence I was put onto labview. I'm trying to set up a GigE camera to work with labview using ImaQdx. So far I've been using the example VI for "grab" as a template to what i want to setup. Other than just grab the image I want to be able to control the frame rate and save a recorded video as a TIFF format file in a folder of my choosing. I attached the file I've made so far. I've gone through a lot of labview tutorials and exercises but have had a few problems. For one, I used imaq write file 2 however if I use the file dialogue as the file path, it will ask my for a file path for every image, not for a "clip" of the images as a whole. I also tried using a time delay to control the frame rate however it's not exact. Is there a better way to control frame rate? One last thing I was wondering is if theres a way to only record sections of the image, i.e. whats currently showing on the screen instead of the whole image.

Thank you for any help
