WHAT I'M TRYING TO DO:

Concatenate a few dozen videos from a directory to form one large video. The videos don't have the same size or aspect ratio, so I'd like for the videos to fit (without stretching) in a 1080x1920 frame and just have the background be black.

MY CODE:

I'm getting the following error:

Exception has occurred: ValueError
could not broadcast input array from shape (1080,1920,3) into shape (1080,1920)

when I run the following code (error comes at the commented line):

from moviepy.editor import *
from os import walk, path

INTRO_VIDEO_PATH = r'C:\Users\jack_L\Downloads\INTRO_VIDEO\INTRO.mp4'
VIDEOS_PATH = r'C:\Users\jack_l\Downloads\DOWNLOADS\folder'

myVideos = next(walk(VIDEOS_PATH), (None, None, []))[2]
finalVideo = []
finalVideo.append(VideoFileClip(INTRO_VIDEO_PATH))

for counter in range(len(myVideos)):
    myExtension = path.splitext(myVideos[counter])[1]
    if myExtension != '.mp4':
        continue
    myVideo = VideoFileClip(VIDEOS_PATH+'\\'+myVideos[counter])
    finalVideo.append(myVideo)

theFinalVideo = concatenate_videoclips(finalVideo, method='compose', bg_color='black')

theFinalVideo.write_videofile(r'C:\Users\jack_l\Downloads\final.mp4') #error at this line

WHAT I KNOW/HAVE BEEN TOLD:

  • "Each frame is a RGB frame, which has 3 channels, but you are trying to fit it into a Greayscale single channel frame." - Sembei Norimaki. Unfortunately, I'm unsure of how I could fix this.

  • Just to inform, an array of (1080,1920,3) is not equal to (1080,1920). The first one consists data of 1080*1920*3 while the latter is only 1080*1920 –  Jun 15 '22 at 14:43
  • @KevinChoonLiangYew Yes but im unsure of where the the 3 is coming from. Why is it doing 1080x1920x3? – THEMOUNTAINSANDTHESKIES Jun 15 '22 at 15:31

SOLUTION:

Removed the bg_color='black' attribute from the theFinalVideo = concatenate_videoclips(finalVideo, method='compose', bg_color='black') line and it worked.
