  • Qualité du média après traitement

    21 juin 2013, par

    Le bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
    Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...)

  • Why does moviepy complain about bitrate while generating audiofile ?

    11 janvier 2017, par Roman

    I have just try to use moviepy library for the first time. Generation of movies from numpy arrays was really simple, intuitive and worked out of box. This is what I tried :

    from moviepy.editor import VideoClip
    
import numpy as np
    

    
def make_frame(t):
    

    
    val = int(255.0*(t/3.0))
    

    
    ls = []
    
    for height in range(100):
    
        row = []
    
        for width in range(300):
    
            row.append([val,0,0])
    
        ls.append(row)
    
    frame = np.array(ls)
    
    return frame
    

    
animation = VideoClip(make_frame, duration = 3)
    

    
animation.write_gif('first_try.gif', fps=24)
    
animation.write_videofile('first_try.mp4', fps=24)

    Then I wanted to use moviepy to generate sound. In theory it should work in a very similar way. Here is what I tried :

    from moviepy.editor import AudioClip
    
import numpy as np
    

    
make_frame = lambda t : 2*[ np.sin(404 * 2 * np.pi * t) ]
    
clip = AudioClip(make_frame, duration=5)
    

    
clip.write_audiofile('sound.mp4')

    However, I got an error message :

    [MoviePy] Writing audio in sound.mp4

  • ffmpeg makes yellow patches in gifs

    23 juillet 2019, par Mc Missile

    I have a bunch of png images made from a python script. When I convert the images to a mp4 format using ffmpeg, the video looks good. But the moment I make them into gifs it starts creating random yellow patches as shown below.
    enter image description here

    The syntax I use to convert png to gif is ffmpeg -i img%04d.png animation.gif

    Thanks.
