Scenes

Scenes are sections of a final video. Each scene contains a start and end frame and an internal list of elements included.

A scene object is stored at graphics.Scene

Scene API

• Scene.__init__(start, end, step, bg_col, before_pause, after_pause, motion_blur)
  • Initializes scene object.
  • Parameter start: Starting frame of export. Usually is 0.
  • Parameter end: Ending frame of export.
  • Parameter step=1: Frame step during export.
  • Parameter before_pause=30: Number of black frames before content starts.
  • Parameter after_pause=30: Number of black frames after content ends.
  • Parameter motion_blur=False: Whether to use Motion Blur. See below for more info.
  • Return: None
• Scene.add_element(element)
  • Appends an element to the internal list.
  • Parameter element: Element to append.
  • Return: None
• Scene.extend_elements(elements)
  • Adds a list of elements to the internal list.
  • Parameter elements: List of elements to append.
  • Return: None
• Scene.render_frame(res, frame)
  • Renders raw frame.
  • Parameter res: Output resolution.
  • Parameter frame: Frame to render.
  • Return: pygame.Surface
• Scene.render(res, frame)
  • Renders post-processed frames. Applies effects like motion blur.
  • Parameter res: Output resolution.
  • Parameter frame: Frame to render.
  • Return: pygame.Surface

Motion Blur

You have the option of enabling motion blur in specific scenes. Motion blur creates simple blurring to improve frames with fast motion.

The current motion blur works by rendering many frames nearby the target frame and combining them with a linear falloff.

This slows down rendering drastically though, so it is not recommended to use motion blur.
