• How to replace the video track in a video file with a still image ?

  22 février 2021, par cornerstore

  I am trying to use ffmpeg to replace the video track in a video file with a still image. I tried some commands I got from other questions such as the one here

  


  ffmpeg -i x.png -i orig.mp4 final.mp4

  


  ffmpeg -r 1/5 -i x.png -r 30 -i orig.mp4 final.mp4

  


  But these didn't work. I'm not sure which of these arguments are required or not. The output should be accepted by YouTube as a valid video - I was able to simply remove the video track, but apparently they don't let you upload a video without a video track.

  


• Quality Drop When Overlaying Images with FFmpeg

  30 octobre 2023, par Мохамед Русланович

  I am using the following command to merge one image with another (overlay one image on top of another) :

  


  ffmpeg -i input.jpg -i merge.png -filter_complex '[1:v]rotate=0:c=none[rotate]; [0:v][rotate]overlay=0:0' -strict experimental -pred 1 -update 1 -frames:v 1 -y output.jpg


  


  However, for some reason, the image quality is decreasing :

  


  

  • The input size is 33KB.

  


  • The output size is 21KB.

  


  


  Additionally, when I add format=auto, the background color changes slightly. How can I fix this issue ?
