[docs]class VideoFileClip(VideoClip): """ A video clip originating from a movie file. For instance: :: >>> clip = VideoFileClip("myHolidays.mp4") >>> clip.close() >>> with VideoFileClip("myMaskVideo.avi") as clip2: >>> pass # Implicit close called by context manager. Parameters ------------ filename: The name of the video file. It can have any extension supported by ffmpeg: .ogv, .mp4, .mpeg, .avi, .mov etc. has_mask: Set this to 'True' if there is a mask included in the videofile. Video files rarely contain masks, but some video codecs enable that. For istance if you have a MoviePy VideoClip with a mask you can save it to a videofile with a mask. (see also ``VideoClip.write_videofile`` for more details). audio: Set to `False` if the clip doesn't have any audio or if you do not wish to read the audio. target_resolution: Set to (desired_height, desired_width) to have ffmpeg resize the frames before returning them. This is much faster than streaming in high-res and then resizing. If either dimension is None, the frames are resized by keeping the existing aspect ratio. resize_algorithm: The algorithm used for resizing. Default: "bicubic", other popular options include "bilinear" and "fast_bilinear". For more information, see fps_source: The fps value to collect from the metadata. Set by default to 'tbr', but can be set to 'fps', which may be helpful if importing slow-motion videos that get messed up otherwise. Attributes ----------- filename: Name of the original video file. fps: Frames per second in the original file. Read docs for Clip() and VideoClip() for other, more generic, attributes. Lifetime -------- Note that this creates subprocesses and locks files. If you construct one of these instances, you must call close() afterwards, or the subresources will not be cleaned up until the process ends. If copies are made, and close() is called on one, it may cause methods on the other copies to fail.
