• FFMPEG trim video resulting not moving videos and black video with audio

  13 juin 2023, par Rafliii

  I tried to trim my video based on start and end time with the following code :

  


  ffmpeg -ss 02:06:30.500 -to 02:06:32.417 -i movie.mp4 -c copy output.mp4

  


  The output video is not moving video and some of them are black videos with audio. What should I do ?

  What should I do ?

  


• 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" ';
  
              }

• 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).
