MoviePy - 设置剪辑的持续时间

在本文中，我们将了解如何在 MoviePy 中设置视频文件剪辑的持续时间。 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。持续时间是播放剪辑的时间，增加持续时间使其重复，减少持续时间将在持续时间完成时关闭剪辑。

In order to do this we will use set_duration method with the VideoFileClip object

Syntax : clip.set_duration(n)

Argument : It takes float value as argument

Return : It returns VideoFileClip object

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)
  
# new clip with new duration
new_clip = clip.set_duration(10)
  
  
# new clip with new duration
new_clip.ipython_display(width = 360)

输出 ：

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 2 seconds
clip = clip.subclip(0, 2)
  
# new clip with new duration
new_clip = clip.set_duration(6)
  
# showing  clip 
new_clip.ipython_display(width = 360) 

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
