This page should give you some insights on the most basic settings and workflows for your project.
Cycles is Blender’s physically-based path tracer for production rendering. It is designed to provide physically based results out-of-the-box, with artistic control and flexible shading nodes for production needs.
Eevee is Blender’s realtime render engine built using OpenGL focused on speed and interactivity while achieving the goal of rendering PBR materials. Eevee can be used interactively in the 3D Viewport but also produce high quality final renders.
Eevee has some limitations but if none of them are critical to your project, the advantage of short render times are really worth it!
To set the render engine go to Blender -> Property Editor -> Render Tab -> Render Engine
Frame rate (expressed in frames per second or FPS) is the frequency (rate) at which consecutive images called frames appear on a display. Unless there is an artistic purpose, the frame rate should be the same in all scenes (files) of your project and since rendering a single frame of your animation will take, depending on the complexity of the scene and the used render engine, something between a few minutes and several hours, it is wise to choose a frame rate at the beginning. Besides that it’s a lot of hard work to remap and fix animations that were done with the wrong frame rate.
14-16 FPS: stop motion look
24 FPS: cinematic look (Blender default)
25 FPS: good compromise between smoothness and render time
30 FPS: max frame rate because all projects have to share one render farm
To set the frame rate go to Blender -> Property Editor -> Output Tab -> Frame Rate
Aspect Ratio / Resolution
There are many different aspect ratios in use that have their own look and feel, for different applications like classic TV, cinema or wide screen displays. What’s more important in relation to the animation is the actual count of pixels, regardless of their arrangement in the x and y direction.
Most of the screens today (at least all the projectors at the HdM) are either full HD (1920×1080 pixels) or ultra HD (3840×2160 pixels). Your chosen aspect ratio must fit inside one of these boundaries.
To set the aspect ratio go to Blender -> Property Editor -> Output Tab -> Resolution X and Y
IMPORTANT! Don’t change Aspect X or Y in this menu as this is the ratio of a single pixel and they are mostly squares (1:1)!
