Why isn't my Matinee saving my images when i capture movie

Hi so i’ve made a matinee and i want to use it for my trailer, i want to record all the images and using the output format and i’ve made it image sequence (jng) frame rate 60 fps resolution 1920x1080 (16:9). when i click capture movie it plays the matinee but then when it’s finished i go to where it is saved in the project folder and there are no images there.

I have made a matinee in another project and did the same thing and all the images are getting saved in that project, any idea why mine wont save in my current project i’m guessing its something to do with the project settings or editor setting and help would be great thanks?
