how to set stills in individual frames?

Hi all,
I would like to know if there is a way to setup different render setting in different frames in Blender?
I have about 8 cameras in my latest interior project and I would like to set different dimensions and amount of samples on each of them. How can I do that?
Can I set each camera in frames 1,2,3, etc. and change their settings for rendering? My goal is to render 8 stills without changing camera dimension every time. I want to save the setting for each camera in different frames…

Could somebody give me some tip?

Best regards,

Though you can automatically switch cameras, render resolution cannot be keyframed. In that case you could create different scenes for every different resolution (add new scenes in top info header).

For better organizing, use 1 scene for the models and lighting. In the other scenes ONLY place the cameras.
In scenes with only the cameras, go the Scene properties. Here you can set the scene with the models + lighting at ‘Background’
