  • Converting a color video to 8-bit (per frame) video via FFMPEG

    25 mai 2020, par SilverSurfer

    I wish to convert a color video file (AVI format) to grayscale video (i.e. 8 bits per frame) AVI video via FFMPEG. Any pointers ?

    



    I have tried using gray and yuv420p options in pix_fmt but it they didn't help.

    



    Thank you

    


  • Create video with size based on image and place a video somewhere with an offset

    10 mars 2024, par NoKey

    I am trying out FFMPEG and I am unsure how hard it is to do what I want. I have some device frames and I want to play a video inside the frame. For example, this is a device frame :

    


    enter image description here

    


    Now I want to play a video within the screen of the iPhone. I already got the exact X and Y offset where the video must be placed to show it correctly. I have the following challenges to make it work, and I want to make sure FFMPEG can do it before I spend to much time reinventing the wheel :

    


      


    • The output of the video must be as big as the PNG. This is already a
confusing part for me. I have the width and height already available,
but the things I saw is that FFMPEG will take over the input of the
video as final size. The final output of the video should of course
be the length of the input video.

      


      • 


    • The background must be transparant (so no black background, I want to
play the video on top of a website so it's nice if it's transparant and the corners are not black).

      


      • 


    • The ability to place a video somewhere with a specified X and Y
offset inside the device frame.

      


      • 


    • Not sure if it's possible in the same command, but maybe the video
needs to be resized to make it fit. I got the exact dimensions for
the video.

      


      • 


    


    The things I struggle most is point 1 where the output video must have a transparant background and where the device frame is placed in. Does anybody got tips ?

    


  • Python add video layer on a video [closed]

    8 juillet 2023, par Doğan

    I have a video in .webm format with a transparent background, and I would like to overlay this .webm video on the right down side of the main video. The main video is in .mp4 format.

    


    Is there any way to do it with python ?
