saving multiple images (AVI frames) in the same folder

[Lanna12]

hello,

I am trying to write a VI, in which I want to save multiple pictures (frames I've extracted from an AVI file) in PNG format in a folder. I have managed to save one frame, but I don't really know how to do that for multiple frames. I know I need to do a "for loop" for getting frames and I need to do a "for loop" for changing the name of an image while saving in a folder, but how do I run a "for loop" on a name of a saved image?   

my VI is included.

thank you!

Typically, you use a string to format a name (e.g. with Format Into String). Use "i" and %d, to get an iteration number in the string. Then use Build Path or String To Path to convert to path.

thank you for replying.

I've tried to do what you suggested, but I'm getting an error and I'm not sure why. 

attaching my VI with the error.

You tried "too hard".  Make the Folder a constant, only build the file name, like this:
