Hope you are doing well.
In The Matinee Actor look for a button that Says ‘Movie’
It is to the Right Of The Red record Button.
When you click the Movie Button you find quite a few options to spit out a movie.
AVI movie Will create an AVI that can be found under your saved files folder.
Using the Image Sequence Options will create a series of still frame images that can be compiled into a movie through a program like Premier. (EX: import numbered stills into premier)
Single frames are often used for FX composites By The Way.
Capture Resolution lets you set the screen resolution the Movies are made at.
I usually use AVI because it does all the Assembly for you.
All of these will render at the specified FPS despite the strength of your machine.
Frames may take a while to render on slower machines but once the movie is created the movies runs at the specified Frame Rate.
Shout if you had any questions about the Tool and Good Luck!
