Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

Why does moviepy complain about bitrate while generating audiofile ?
6 octobre 2023, par RomanI have just try to use
moviepylibrary for the first time. Generation of movies fromnumpyarrays 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
moviepyto 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 :

Does anybody know what this error means and how this problem can be resolved ?
