# Import everything needed to edit video clips from moviepy.editor import * # loading video gfg clip = VideoFileClip("video.mp4") # getting subclip from it clip = clip.subclip(0, 9) # applying color effect final = clip.fx( vfx.colorx, 0.3) # showing final clip final.ipython_display() |
As you can see we are importing the moviepy library at the very top and then we are only taking the first 9 seconds of the input video using the subclip()method and then we are applying the color effect or changing the opacity of the video using the fx() method and inside it we are providing the numerical value if the value is larger then the opacity of the video will increase. And if the value is closer to 0 then the video will be more black in color as shown below
