  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Blending Videos in FFmpeg : Excluding Transparent Areas from the Blend [closed]

    12 novembre 2024, par li lu

    I have two videos : one background video and one foreground video (with doves flying, containing an alpha channel). I want to blend these two videos so that only the dove parts participate in the blending, while the transparent parts do not. When I use the ffmpeg blend filter, the overall color of the output video changes, as if the entire video is being blended.

    


  • Guidance on Implementing Custom Designs and Background Effects for Videos [closed]

    23 septembre 2023, par Joel Smith

    I am currently developing a web application that allows users to upload videos on the frontend. The primary goal of my project is to enable users to add custom designs to their videos and apply background effects. I'm using Python for the backend to handle video processing.

    


    I'm seeking advice on the appropriate technologies, libraries, or approaches to achieve the following :

    


      

    1. Custom Designs : I want to provide users with the ability to overlay custom graphics or text onto their videos. What Python libraries or tools can I use to achieve this ? Are there any best practices for adding graphics and text to videos dynamically ?

      2. 


    2. Background Effects : I need to implement the feature to add background effects to uploaded videos. How can I achieve this, and what are the recommended methods or libraries for background replacement or manipulation ?

      3. 


    3. Shadow Effects : Additionally, I want to enhance the visual appeal of the videos by adding shadow effects to elements like text or custom designs. What techniques or tools should I explore to achieve this effect ?
4.Combining Videos : To apply background effects, I need to merge the uploaded video with a background video or image seamlessly. What is the best approach to combine videos and maintain video quality during the process ?

      4. 


    


    I have already implemented the frontend video upload to the backend and would appreciate any insights, code examples, or recommendations that can help me achieve these features effectively.
