In this article we will see how we can change display frames and time line of the video file clip in MoviePy at a same time. MoviePy is a Python module for video editing, which can be used for basic operations on videos and GIF’s. We use fl_image
method to alter the display frames and fl_time
method to alter the time, although we can do these task at a same time.
In order to do this we will use
fl
method with the VideoFileClip objectSyntax : clip.fl(method)
Argument : It takes time method as argument
Return : It returns VideoFileClip object
Below is the implementation
# Import everything needed to edit video clips from moviepy.editor import *
# loading video dsa gfg intro video 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() |
Output :
Moviepy - Building video __temp__.mp4. Moviepy - Writing video __temp__.mp4 Moviepy - Done ! Moviepy - video ready __temp__.mp4
Another example
# 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() |
Output :
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 ! Moviepy - video ready __temp__.mp4
