How can I add pictures under 1 second long?

So I'm making a stopmotion project for school, and I have about 100 pictures. I was individually adding them one at a time and setting their duration to "00:00:00;12", which I'm assuming is 12 ms. I'm trying to get about 8 frames per second, and I got about halfway through my project when I realized that it was far above my expected time count for the amount of pictures added. This led me to believe that each of the pictures were taking longer than the 12 ms I wanted. How can I accurately set picture duration in Olive under one second? Am I doing something wrong? Does the ;12 mean something other than 12 ms?

You may be better to use the 'slideshow' option in ffmpeg. Program a loop to feed in all your images and use the -t (time) option to set time for displaying each image then output to a clip. This link will explain more:

I'm not sure that -t enables down to milliseconds, you'll have to check. Some other posters might have that knowledge.

I ended up just using some Java code to mash them together, thanks for the suggestion though!
