Clip.subclip
|
(self, start_time=0, end_time=None)
|
return new_clip
|
Returns a clip playing the content of the current clip between times
``start_time`` and ``end_time``, which can be expressed in seconds
(15.35), in (min, sec), in (hour, min, sec), or as a string:
'01:03:05.35'.
The ``mask`` and ``audio`` of the resulting subclip will be subclips of
``mask`` and ``audio`` the original clip, if they exist.
Parameters
----------
start_time : float or tuple or str, optional
Moment that will be chosen as the beginning of the produced clip. If
is negative, it is reset to ``clip.duration + start_time``.
end_time : float or tuple or str, optional
Moment that will be chosen as the end of the produced clip. If not
provided, it is assumed to be the duration of the clip (potentially
infinite). If is negative, it is reset to ``clip.duration + end_time``.
For instance:
>>> # cut the last two seconds of the clip:
>>> new_clip = clip.subclip(0, -2)
If ``end_time`` is provided or if the clip has a duration attribute,
the duration of the returned clip is set automatically.

Clip.cutout
|
(self, start_time, end_time)
|
Returns a clip playing the content of the current clip but
skips the extract between ``start_time`` and ``end_time``, which can be
expressed in seconds (15.35), in (min, sec), in (hour, min, sec),
or as a string: '01:03:05.35'.
If the original clip has a ``duration`` attribute set,
the duration of the returned clip is automatically computed as
`` duration - (end_time - start_time)``.
The resulting clip's ``audio`` and ``mask`` will also be cutout
if they exist.
Parameters
----------
start_time : float or tuple or str
Moment from which frames will be ignored in the resulting output.
end_time : float or tuple or str
Moment until which frames will be ignored in the resulting output.

Clip.iter_frames
|
(self, fps=None, with_times=False, logger=None, dtype=None)
|
Iterates over all the frames of the clip.
Returns each frame of the clip as a HxWxN Numpy array,
where N=1 for mask clips and N=3 for RGB clips.
This function is not really meant for video editing. It provides an
easy way to do frame-by-frame treatment of a video, for fields like
science, computer vision...
Parameters
----------
fps : int, optional
Frames per second for clip iteration. Is optional if the clip already
has a ``fps`` attribute.
with_times : bool, optional
Ff ``True`` yield tuples of ``(t, frame)`` where ``t`` is the current
time for the frame, otherwise only a ``frame`` object.
logger : str, optional
Either ``"bar"`` for progress bar or ``None`` or any Proglog logger.
dtype : type, optional
Type to cast Numpy array frames. Use ``dtype="uint8"`` when using the
pictures to write video, images...
Examples
--------
>>> # prints the maximum of red that is contained
>>> # on the first line of each frame of the clip.
>>> from moviepy import VideoFileClip
>>> myclip = VideoFileClip('myvideo.mp4')
>>> print ( [frame[0,:,0].max()
for frame in myclip.iter_frames()])

Writes an audio file from the AudioClip.
Parameters
----------
filename
Name of the output file, as a string or a path-like object.
fps
Frames per second. If not set, it will try default to self.fps if
already set, otherwise it will default to 44100.
nbytes
Sample width (set to 2 for 16-bit sound, 4 for 32-bit sound)
codec
Which audio codec should be used. If None provided, the codec is
determined based on the extension of the filename. Choose
'pcm_s16le' for 16-bit wav and 'pcm_s32le' for 32-bit wav.
bitrate
Audio bitrate, given as a string like '50k', '500k', '3000k'.
Will determine the size and quality of the output file.
Note that it mainly an indicative goal, the bitrate won't
necessarily be the this in the output file.
ffmpeg_params
Any additional parameters you would like to pass, as a list
of terms, like ['-option1', 'value1', '-option2', 'value2']
write_logfile
If true, produces a detailed logfile named filename + '.log'
when writing the file
logger
Either ``"bar"`` for progress bar or ``None`` or any Proglog logger.

preview
|
(
clip, fps=22050, buffersize=4000, nbytes=2, audio_flag=None, video_flag=None
)
|
Plays the sound clip with pygame.
Parameters
----------
fps
Frame rate of the sound. 44100 gives top quality, but may cause
problems if your computer is not fast enough and your clip is
complicated. If the sound jumps during the preview, lower it
(11025 is still fine, 5000 is tolerable).
buffersize
The sound is not generated all at once, but rather made by bunches
of frames (chunks). ``buffersize`` is the size of such a chunk.
Try varying it if you meet audio problems (but you shouldn't
have to).
nbytes:
Number of bytes to encode the sound: 1 for 8bit sound, 2 for
16bit, 4 for 32bit sound. 2 bytes is fine.
audio_flag, video_flag:
Instances of class threading events that are used to synchronize
video and audio during ``VideoClip.preview()``.

Repeats audio certain number of times at constant intervals multiplying
their volume levels using a linear space in the range 1 to ``decay`` argument
value.
Parameters
----------
offset : float, optional
Gap between repetitions start times, in seconds.
n_repeats : int, optional
Number of repetitions (without including the clip itself).
decay : float, optional
Multiplication factor for the volume level of the last repetition. Each
repetition will have a value in the linear function between 1 and this value,
increasing or decreasing constantly. Keep in mind that the last repetition
will be muted if this is 0, and if is greater than 1, the volume will increase
for each repetition.
Examples
--------

)
|
Write the clip to a videofile.
Parameters
----------
filename
Name of the video file to write in, as a string or a path-like object.
The extension must correspond to the "codec" used (see below),
or simply be '.avi' (which will work with any codec).
fps
Number of frames per second in the resulting video file. If None is
provided, and the clip has an fps attribute, this fps will be used.
codec
Codec to use for image encoding. Can be any codec supported
by ffmpeg. If the filename is has extension '.mp4', '.ogv', '.webm',
the codec will be set accordingly, but you can still set it if you
don't like the default. For other extensions, the output filename
must be set accordingly.
Some examples of codecs are:
- ``'libx264'`` (default codec for file extension ``.mp4``)
makes well-compressed videos (quality tunable using 'bitrate').
- ``'mpeg4'`` (other codec for extension ``.mp4``) can be an alternative
to ``'libx264'``, and produces higher quality videos by default.
- ``'rawvideo'`` (use file extension ``.avi``) will produce
a video of perfect quality, of possibly very huge size.
- ``png`` (use file extension ``.avi``) will produce a video
of perfect quality, of smaller size than with ``rawvideo``.
- ``'libvorbis'`` (use file extension ``.ogv``) is a nice video
format, which is completely free/ open source. However not
everyone has the codecs installed by default on their machine.
- ``'libvpx'`` (use file extension ``.webm``) is tiny a video
format well indicated for web videos (with HTML5). Open source.
audio
Either ``True``, ``False``, or a file name.
If ``True`` and the clip has an audio clip attached, this
audio clip will be incorporated as a soundtrack in the movie.
If ``audio`` is the name of an audio file, this audio file
will be incorporated as a soundtrack in the movie.
audio_fps
frame rate to use when generating the sound.
temp_audiofile
the name of the temporary audiofile, as a string or path-like object,
to be created and then used to write the complete video, if any.
temp_audiofile_path
the location that the temporary audiofile is placed, as a
string or path-like object. Defaults to the current working directory.
audio_codec
Which audio codec should be used. Examples are 'libmp3lame'
for '.mp3', 'libvorbis' for 'ogg', 'libfdk_aac':'m4a',
'pcm_s16le' for 16-bit wav and 'pcm_s32le' for 32-bit wav.
Default is 'libmp3lame', unless the video extension is 'ogv'
or 'webm', at which case the default is 'libvorbis'.
audio_bitrate
Audio bitrate, given as a string like '50k', '500k', '3000k'.
Will determine the size/quality of audio in the output file.
Note that it mainly an indicative goal, the bitrate won't
necessarily be the this in the final file.
preset
Sets the time that FFMPEG will spend optimizing the compression.
Choices are: ultrafast, superfast, veryfast, faster, fast, medium,
slow, slower, veryslow, placebo. Note that this does not impact
the quality of the video, only the size of the video file. So
choose ultrafast when you are in a hurry and file size does not
matter.
threads
Number of threads to use for ffmpeg. Can speed up the writing of
the video on multicore computers.
ffmpeg_params
Any additional ffmpeg parameters you would like to pass, as a list
of terms, like ['-option1', 'value1', '-option2', 'value2'].

Either ``"bar"`` for progress bar or ``None`` or any Proglog logger.
pixel_format
Pixel format for the output video file.
Examples
--------

"""Write the clip to a videofile.
Parameters
----------
filename
Name of the video file to write in, as a string or a path-like object.
The extension must correspond to the "codec" used (see below),
or simply be '.avi' (which will work with any codec).
fps
Number of frames per second in the resulting video file. If None is
provided, and the clip has an fps attribute, this fps will be used.
codec
Codec to use for image encoding. Can be any codec supported
by ffmpeg. If the filename is has extension '.mp4', '.ogv', '.webm',
the codec will be set accordingly, but you can still set it if you
don't like the default. For other extensions, the output filename
must be set accordingly.
Some examples of codecs are:
- ``'libx264'`` (default codec for file extension ``.mp4``)
makes well-compressed videos (quality tunable using 'bitrate').
- ``'mpeg4'`` (other codec for extension ``.mp4``) can be an alternative
to ``'libx264'``, and produces higher quality videos by default.
- ``'rawvideo'`` (use file extension ``.avi``) will produce
a video of perfect quality, of possibly very huge size.
- ``png`` (use file extension ``.avi``) will produce a video
of perfect quality, of smaller size than with ``rawvideo``.
- ``'libvorbis'`` (use file extension ``.ogv``) is a nice video
format, which is completely free/ open source. However not
everyone has the codecs installed by default on their machine.
- ``'libvpx'`` (use file extension ``.webm``) is tiny a video
format well indicated for web videos (with HTML5). Open source.
audio
Either ``True``, ``False``, or a file name.
If ``True`` and the clip has an audio clip attached, this
audio clip will be incorporated as a soundtrack in the movie.
If ``audio`` is the name of an audio file, this audio file
will be incorporated as a soundtrack in the movie.
audio_fps
frame rate to use when generating the sound.
temp_audiofile
the name of the temporary audiofile, as a string or path-like object,
to be created and then used to write the complete video, if any.
temp_audiofile_path
the location that the temporary audiofile is placed, as a
string or path-like object. Defaults to the current working directory.
audio_codec
Which audio codec should be used. Examples are 'libmp3lame'
for '.mp3', 'libvorbis' for 'ogg', 'libfdk_aac':'m4a',
'pcm_s16le' for 16-bit wav and 'pcm_s32le' for 32-bit wav.
Default is 'libmp3lame', unless the video extension is 'ogv'
or 'webm', at which case the default is 'libvorbis'.
audio_bitrate
Audio bitrate, given as a string like '50k', '500k', '3000k'.
Will determine the size/quality of audio in the output file.
Note that it mainly an indicative goal, the bitrate won't
necessarily be the this in the final file.
preset
Sets the time that FFMPEG will spend optimizing the compression.
Choices are: ultrafast, superfast, veryfast, faster, fast, medium,
slow, slower, veryslow, placebo. Note that this does not impact
the quality of the video, only the size of the video file. So
choose ultrafast when you are in a hurry and file size does not
matter.
threads
Number of threads to use for ffmpeg. Can speed up the writing of
the video on multicore computers.
ffmpeg_params
Any additional ffmpeg parameters you would like to pass, as a list
of terms, like ['-option1', 'value1', '-option2', 'value2'].
write_logfile
If true, will write log files for the audio and the video.
These will be files ending with '.log' with the name of the
output file in them.
logger
Either ``"bar"`` for progress bar or ``None`` or any Proglog logger.
pixel_format
Pixel format for the output video file.

Write the VideoClip to a GIF file.
Converts a VideoClip into an animated GIF using ImageMagick
or ffmpeg.
Parameters
----------
filename
Name of the resulting gif file, as a string or a path-like object.
fps
Number of frames per second (see note below). If it
isn't provided, then the function will look for the clip's
``fps`` attribute (VideoFileClip, for instance, have one).
program
Software to use for the conversion, either 'imageio' (this will use
the library FreeImage through ImageIO), or 'ImageMagick', or 'ffmpeg'.
opt
Optimalization to apply. If program='imageio', opt must be either 'wu'
(Wu) or 'nq' (Neuquant). If program='ImageMagick',
either 'optimizeplus' or 'OptimizeTransparency'.
fuzz
(ImageMagick only) Compresses the GIF by considering that
the colors that are less than fuzz% different are in fact
the same.
tempfiles
Writes every frame to a file instead of passing them in the RAM.
Useful on computers with little RAM. Can only be used with
ImageMagick' or 'ffmpeg'.
progress_bar
If True, displays a progress bar
pixel_format
Pixel format for the output gif file. If is not specified
'rgb24' will be used as the default format unless ``clip.mask``
exist, then 'rgba' will be used. This option is only going to
be accepted if ``program=ffmpeg`` or when ``tempfiles=True``
Notes
-----
The gif will be playing the clip in real time (you can
only change the frame rate). If you want the gif to be played
slower than the clip you will use ::
>>> # slow down clip 50% and make it a gif
>>> myClip.multiply_speed(0.5).to_gif('myClip.gif')

BitmapClip.__init__
|
(
self, bitmap_frames, *, fps=None, duration=None, color_dict=None, is_mask=False
)
|
Creates a VideoClip object from a bitmap representation. Primarily used
in the test suite.
Parameters
----------
bitmap_frames
A list of frames. Each frame is a list of strings. Each string
represents a row of colors. Each color represents an (r, g, b) tuple.
Example input (2 frames, 5x3 pixel size)::
[["RRRRR",
"RRBRR",
"RRBRR"],
["RGGGR",
"RGGGR",
"RGGGR"]]
fps
The number of frames per second to display the clip at. `duration` will
calculated from the total number of frames. If both `fps` and `duration`
are set, `duration` will be ignored.
duration
The total duration of the clip. `fps` will be calculated from the total
number of frames. If both `fps` and `duration` are set, `duration` will
be ignored.
color_dict
A dictionary that can be used to set specific (r, g, b) values that
correspond to the letters used in ``bitmap_frames``.
eg ``{"A": (50, 150, 150)}``.
Defaults to::
{
"R": (255, 0, 0),
"G": (0, 255, 0),
"B": (0, 0, 255),
"O": (0, 0, 0), # "O" represents black
"W": (255, 255, 255),
# "A", "C", "D", "E", "F" represent arbitrary colors
"A": (89, 225, 62),
"C": (113, 157, 108),
"D": (215, 182, 143),
"E": (57, 26, 252),
}
is_mask
Set to ``True`` if the clip is going to be used as a mask.

Find the period of a video based on frames correlation.
Parameters
----------
clip : moviepy.Clip.Clip
Clip for which the video period will be computed.
fps : int, optional
Number of frames per second used computing the period. Higher values will
produce more accurate periods, but the execution time will be longer.

|
(
clip=None, luminosities=None, luminosity_threshold=10, logger="bar", fps=None
)
|
return cuts, luminosities
|
Detects scenes of a clip based on luminosity changes.
Note that for large clip this may take some time.
Returns
-------
tuple : cuts, luminosities
cuts is a series of cuts [(0,t1), (t1,t2),...(...,tf)]
luminosities are the luminosities computed for each
frame of the clip.
Parameters
----------
clip : video.VideoClip.VideoClip, optional
A video clip. Can be None if a list of luminosities is
provided instead. If provided, the luminosity of each
frame of the clip will be computed. If the clip has no
'fps' attribute, you must provide it.
luminosities : list, optional
A list of luminosities, e.g. returned by detect_scenes
in a previous run.
luminosity_threshold : float, optional
Determines a threshold above which the 'luminosity jumps'
will be considered as scene changes. A scene change is defined
as a change between 2 consecutive frames that is larger than
(avg * thr) where avg is the average of the absolute changes
between consecutive frames.
logger : str, optional
Either ``"bar"`` for progress bar or ``None`` or any Proglog logger.
fps : int, optional
Frames per second value. Must be provided if you provide
no clip or a clip without fps attribute.
