• How to convert 4:3 video to 16:9 without stretching the original in ffmpeg

  5 novembre 2016, par carvil

  I would like to convert some 4:3 videos that I took on an iPhone to 16:9, by adding black bars to both sides instead of stretching the video.

  I tried something like this without success :

  ffmpeg -y -i input.mov -aspect 1.7777777777777777 -s 640x360 output.mp4

  Even though the output has the correct size, the video is stretched, which is not what I want.

  How can I keep the proportion between the width and height of the original video, and add extra black bars to both sides to avoid stretching ?

  This would be similar to how YouTube does it when uploading a video from an iPhone directly to YouTube.

  Thanks !
