  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Video is black when framerate is too low using imageio and Python

    28 juin 2018, par palimboa

    I have the following exmaple code :

    import numpy as np
    
writer = imageio.get_writer('test.mp4', fps=1)
    

    
max = 800
    
resolution = 256
    

    
for idx in range(1, max):
    
    img = np.zeros((resolution,resolution))
    
    img[: int((idx / max) * resolution), : int((idx / max) * resolution)] = 255
    
    img = img.astype(np.uint8)
    
    writer.append_data(img)
    

    
writer.close()

    The video is just black for fps == 1

    What am I missing here ? I cannot see any clues in the documentation saying I cannot have fps = 1 ?

    EDIT

    For fps >= 10 it seems to be fine.

  • FFMPEG CROP BLACK BARS BAD QUALITY

    9 janvier 2020, par Gustavo Gonzalez

    Hello im using this command to remove the black bars and make the video fullscreen ,

    ffmpeg -i 1.mkv -vf "crop=1920:800:0:140,scale=1920:1080,setsar=1" -c:v h264_nvenc -rc:v vbr_hq -cq:v 0 -b:v 27000k -maxrate:v 26000k -profile:v high -preset slow og1.mkv

    It works good ,
    But the problem is the quality of the video, there is a lot of difference between the original and the new,and apart from that it’s like the video is a bit stretched because of the new crop settings.

  • FFMpeg set alpha channel transparent for black pixels

    1er avril 2023, par Pete

    I'm using ffmpeg for a bunch of my video workflows. I need to learn how to replace the alpha channel for the black pixels to be transparent. The video I'm working with is ProRes 4444. Here is a link to a
Sample video file. It seems it should be easy but I'm having a hard time figuring out how to do it. Thanks in advance for helping !
