HD resolution

I’m trying to make a stop motion project with 1920x1080 pictures. I downloaded the trial version of iStopMotion for Mac and it will only allow me pictures as wide as 960. Also, I would like to use 24 FPS but I only see 25 FPS in the HD options. I would output it in NTSC rather than PAL.
Is that possible with this sofware? Do I need another version?
Thank you.

iStopMotion is restricted in the resolution in demo mode. Once you bought it, you are able to enter any resolution you want and also setting up the fps is possible (select “Preset: Customized” in the “New Document” dialog). Please be aware that you have to setup those values when creating the project, they can’t be changed later on.
