MoviePy - 设置剪辑的 FPS

在本文中，我们将了解如何在 MoviePy 中设置视频文件剪辑的 fps。 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。帧速率是称为帧的连续图像出现在显示器上的频率。该术语同样适用于电影和摄像机、计算机图形和动作捕捉系统。帧率也可以称为帧频，以赫兹表示。

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

Syntax : clip.set_fps(n)

Argument : It takes integer 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 fps
new_clip = clip.set_fps(5)
  
# displaying new clip
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 5 seconds
clip = clip.subclip(0, 5)
  
# new clip with new fps
new_clip = clip.set_fps(100)
  
# displaying new 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
