Batch Scripting : How to file name based on Increment int

[Brainiac]

Hi

First of all ,i`m new here so HI to everyone .

I'm having trouble on writing some code on a Batch Script ,so I'm using ffmpeg (a Software for Video Encoding/Transcoding),and than i plan to call that batch script on a C# Application .

So far i now a command which does that ,if i type it on Command Prompt ,but using a batch script that can not be done .

So here is my command :

ffmpeg -i video.mpg -r 1 -s 1024x720 -f image2 img-%03d.jpeg

So with that command i can save a single image for each frame of an input video ,and it will save images like image img-001.jpg ,img-002.jpg and so far ,but i need to do the came with a batch script or is there a way to send the command like it is on Terminal (command promt) because i can not understand as well what that mean ,i just now that is a C syntax .

Sory for the long post but i need to be clear

Best on advance
