Parameters ---------- clip : VideoClip The clip to preview fps : int Number of frames per seconds in the displayed video. pixel_format : str, optional Warning: This is not used anywhere in the code and should probably be removed. It is believed pixel format rgb24 does not work properly for now because it requires applying a mask on CompositeVideoClip and that is believed to not be working. Pixel format for the output video file, ``rgb24`` for normal video, ``rgba`` if video with mask audio_flag : Thread.Event, optional A thread event that video will wait for. If not provided we ignore audio video_flag : Thread.Event, optional A thread event that video will set after first frame has been shown.
