  • Using FFMPEG, how do we add subtitles in the black bar area or under the video ?

    26 septembre 2020, par DunceDancer

    I followed these steps :

    


      


    1. Added the black bars

      


      -vf "scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080 :(ow-iw)/2 :(oh-ih)/2,setsar=1" Source :How to add black borders to video

      


      2. 


    2. Added the subtitles ("burned" it into the video)

      


      ffmpeg -i "imput.mp4" -lavfi "subtitles=subtitles.srt:force_style='Alignment=0,OutlineColour=&H100000000,BorderStyle=3,Outline=1,Shadow=0,Fontsize=18,MarginL=5,MarginV=25'" -crf 1 -c:a copy "output.mp4" Source : ffmpeg subtitles alignment and position

      


      3. 


    


    Now I am stuck as to how to place the subtitles under the video or in the black screen.

  • FFMPEG Replacing black color fragments with alpha channel transperency

    31 décembre 2017, par kostya572

    I have "file.mov" video. It has a lot of blank black color fragments that have different durations.

    I need to replace black color fragments that durates more than 5 seconds with transparency ? Is that possible to add some alpha channel for that purpose ?

  • Convert video to hequirect while setting the background black and blur the transitional area [closed]

    11 février 2024, par Zurechtweiser

    I am using

    


    ffmpeg -i input.mp4 -vf "v360=input=fisheye:ih_fov=122.6:iv_fov=94.4:output=hequirect:h_fov=180:v_fov=180:in_stereo=2d:out_stereo=sbs,format=yuv420p" -b:v 25M -maxrate 60M -bufsize 25M output.mp4


    


    Which works as advertised to convert a fisheye to hequirect except for two problems :

    


      


    1. The background is not black but seems to try and set it to the average color of the video. It should be black throughout.

      


      2. 


    2. The corners are not blurred but should be, there should be a soft transition from the corner of the video into black.

      


      3.
