MoviePy - 更改视频剪辑的显示帧

在本文中，我们将了解如何在 MoviePy 中更改视频文件剪辑的显示帧。 MoviePy 是一个用于视频编辑的Python模块，可用于视频和 GIF 的基本操作。显示帧是单个图像，即视频的单帧，视频由许多帧组成，我们可以使用moviepy更改显示帧。

In order to do this we will use fl_image method with the VideoFileClip object
Syntax : clip.fl_image(method)
Argument : It takes time method as argument
Return : It returns VideoFileClip object 
 

下面是实现

Python3

# Import everything needed to edit video clips
from moviepy.editor import *
 
  
# loading video dsa gfg intro video
clip = VideoFileClip("dsa_geek.webm")
  
# getting only first 5 seconds
clip = clip.subclip(0, 5)
 
# method for inverting image
def invert_image(image):
    return image[:, :, [0, 2, 0]]
 
# inverting image
final = clip.fl_image(invert_image)
 
# showing final clip
final.ipython_display()

输出 ：

Moviepy - Building video __temp__.mp4.
Moviepy - Writing video __temp__.mp4

                                                                                                                       
Moviepy - Done !
Moviepy - video ready __temp__.mp4
 

另一个例子：

Python3

# Import everything needed to edit video clips
from moviepy.editor import *
 
# loading video gfg
clip = VideoFileClip("geeks.mp4")
 
 
# getting subclip from it
clip = clip.subclip(0, 5)
 
# method for inverting image
def invert_image(image):
    return image[:, :, [1, 2, 1]]
 
# inverting image
final = clip.fl_image(invert_image)
 
# showing final clip
final.ipython_display()

输出：

Moviepy - Building video __temp__.mp4.
MoviePy - Writing audio in __temp__TEMP_MPY_wvf_snd.mp3
                                                                                                                       
MoviePy - Done.
Moviepy - Writing video __temp__.mp4

                                                                                                                       
Moviepy - Done !
Moviepy - video ready __temp__.mp4
