  Is it possible to give a video as a reference for compression, resolution, codec to enact on another video ? So it will be easier to make videos the same instead of manually

  


• moviepy output video only has sound in vs code and chrome but not in quicktime (the mac video player)

  24 janvier 2023, par UrLocalGoose

  I am using moviepy to make simple videos that require adding background music to a video. I have built essentially the whole application but I ran into a problem when showing people the videos. I tried emailing myself the video and it didn't have any sound, then I tried to play the video with the built in mac video player, quicktime, and it didn't have any sound, however, when I played the video in vs code's video player it worked perfectly, I also used the file path to view the video in chrome, and that worked too. I suspect that it has something to do with the encoding but I am a novice when it comes to video and audio encoding. This is what my code looks like :

  


  from moviepy.editor import *

background_video = VideoFileClip("./background.mp4")

background_music_audio = AudioFileClip("./music.wav")

comp = background_video.set_audio(background_music_audio)

comp.write_videofile("./test.mp4")


  


  I tried to make a video with background music but it had no sound
