vuba.VideoGUI

class vuba.VideoGUI(video, indices=(None, None), *args, **kwargs)[source]

Class for creating interfaces for manipulating a sequence of frames.

Parameters

  • video (vuba.Video) – Video to manipulate within the interface.

  • indices (tuple) – Frame indices to limit GUI to, especially useful when analysing long sequences of footage. First index will always be interpreted as the minimum index and the second as the maximum index. If None is specified to either limit, then that limit will be ignored. Default is for no limits, i.e. (None, None).

  • title (str) – Title of the interface window.

Returns

gui – Class object for creating the interactive window.

Return type

VideoGUI
