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
flmethod 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("neveropen.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
