在本文中, 我们将看到如何在MoviePy中同时更改视频文件剪辑的显示帧和时间线。 MoviePy是用于视频编辑的Python模块, 可用于对视频和GIF进行基本操作。我们用fl_image更改显示框架的方法fl_time更改时间的方法, 尽管我们可以同时执行这些任务。
为此, 我们将fl方法与VideoFileClip对象一起使用语法：clip.fl(method)参数：需要时间方法作为参数返回：返回VideoFileClip对象
下面是实现
# 导入一切需要编辑视频剪辑
from moviepy.editor import *
# 加载视频dsa gfg介绍视频
clip = VideoFileClip( "dsa_geek.webm" )
# getting only first 5 seconds
clip = clip.subclip( 0 , 5 )
def scroll(get_frame, t):
"""
This function returns a 'region' of the current frame.
The position of this region depends on the time.
"""
frame = get_frame(t)
frame_region = frame[ int (t): int (t) + 360 , :]
return frame_region
# alter time and frame
final = clip.fl( scroll )
# 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 duration of the video
duration = clip.duration
def scroll(get_frame, t):
"""
This function returns a 'region' of the current frame.
The position of this region depends on the time.
"""
frame = get_frame(t)
frame_region = frame[ int (t): int (t) + 360 , :]
return frame_region
# alter time and frame
final = clip.fl( scroll )
# showing final clip
final.ipython_display()输出：
Duration : 10.98
Moviepy - Building video __temp__.mp4.
MoviePy - Writing audio in __temp__TEMP_MPY_wvf_snd.mp3
MoviePy - Done.
Moviepy - Writing video __temp__.mp4
Moviepy - Done !
