MoviePy - 改变视频剪辑的时间线
在本文中,我们将了解如何在 MoviePy 中更改视频文件剪辑的时间线。 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。在视频编辑中,时间线是大多数视频编辑程序中常用的界面。该界面使作者能够以线性方式在监视器上水平放置视频项目。在非线性编辑系统中按时间顺序显示已编辑序列。通过改变视频的时间线,我们可以改变视频中事件的顺序。
In order to do this we will use fl_time
method with the VideoFileClip object
Syntax : clip.fl_time(method)
Argument : It takes time method as argument
Return : It returns VideoFileClip object
下面是实现
# Import everything needed to edit video clips
from moviepy.editor import * import math
# loading video dsa gfg intro video
clip = VideoFileClip("dsa_geek.webm")
# getting only first 5 seconds
clip = clip.subclip(0, 5)
# applying color effect
final = clip.fl_time(lambda t: math.sin(t))
# setting duration
final.duration = 9
# 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
# 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)
# altering time intervalr effect
final = clip.fl_time(lambda t: 2 * t)
# setting duration
final.duration = 10
# 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
