MoviePy - 检查视频文件剪辑的掩码

在本文中，我们将了解如何检查 MoviePy 中的视频文件剪辑是否是蒙版视频。 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。 IsMask 属性告诉如果给定的视频剪辑是否为掩码，掩码基本上是用作另一个视频的掩码的视频。我们可以借助set_ismask方法将视频剪辑制作为遮罩。

In order to do this we will use ismask attribute with the VideoFileClip object

Syntax : clip.ismask

Argument : It takes no argument

Return : It returns bool

下面是实现

# Import everything needed to edit video clips 
from moviepy.editor import *
    
# loading video dsa gfg intro video 
clip = VideoFileClip("dsa_geek.mp4") 
     
# getting only first 5 seconds
clip = clip.subclip(0, 5)
  
# checking if clip is mask
value = clip.ismask
  
# printing value
print("Clip is Mask ", end = " : ")
print(value)
  
  
# displaying new clip
clip.ipython_display(width = 420)

输出 ：

Clip is Mask  : False
Moviepy - Building video __temp__.mp4.
Moviepy - Writing video __temp__.mp4

                                                                                                                       
Moviepy - Done !
Moviepy - video ready __temp__.mp4

另一个例子

# Import everything needed to edit video clips
from moviepy.editor import *
  
# loading video gfg
clip = VideoFileClip("geeks.mp4")
  
  
# getting only first 5 seconds
clip = clip.subclip(0, 5)
  
# masking this clip as amsk
clip = clip.set_ismask(True)
  
# checking if clip is mask
value = clip.ismask
  
# printing value
print("Clip is Mask ", end = " : ")
print(value)
  
# displaying new clip
clip.ipython_display()

输出 ：

Clip is Mask  : True
