• use audio in video to write video subtitles [on hold]

  17 septembre 2015, par armoured

  wanted to know how to extract audio from a video clip, then convert the audio to text, and use the text as the subtitles to the video, which is to be broken into smaller clips. The idea was to have several clips of the same video with different subtitles, and then combine the clips into one nic video. I am doing this using python, and moviepy in particular. Tried it, but don’t know how to extract change audio in a video to text in moviepy, please help

• FFMPEG fit 1920x1080 video in 1080x1920 video (Instagram Reels)

  10 mars 2021, par tjallo

  I am trying to post a video on Instagram. My current video is 1920x1080, but for Instagram reels it needs to be in 1080x1920 resolution (Basically Vertical). But instead of posting the video on its side, I like to post it with black bars (see image below). But I don't know which transform commands I need to use in ffmpeg to make this work (and also couldn't find any relevant posts).

  


  

  


• How to put watermak on video with FFMPEG,without resizing the watermark because of video resolution ?

  22 mai 2014, par Shahbaz Younis

  I’m looking for a way that the watermark picture does not get resized,if the video resolution is high or less. Right now I have this problem, if I upload a video like 720p the watermark is really small and when I upload a video that is 240p the watermark is really big. I would just like it to be only one size. Can it do that automatically ? So no matter what the resolution is the of the video the image does not resizes and stays where I put it ? Here’s the code I’m using right now

  if ($ffmpeg_ver == "old") {
  
                      $watermark = '-vf "movie='.$tv_logo_path.' [watermark]; [in][watermark] overlay=10:10 [out]" ';
  
              } else { 
  
                      $watermark = '-i '.$tv_logo_path.' -filter_complex "overlay=10:10" ';
  
              }
