Trade-offs, settings and output¶
Here, we look into trade-offs that you can make in terms of chosen frame rate, animation length, quality, etc.
Secondly, we will look in detail into the different settings available for an animation, including the type of output (images or video file) and strategies to handle long render times. We also describe how to do command-line rendering.
Easy command-line rendering¶
If you have set up the animation and its settings (i.e. frame rate, start & end frame, output name, etc) as you like in the Blender filem then rendering from the command-line usually doesn't involve much more than running this command:
The -b option makes sure Blender renders in the background without opening a window. The -a starts animation rendering,
as if you had pressed Ctrl+F12 or Render > Render Animation in the UI. You only need to add extra options if you want to override values set in the Blender file.
