How can I convert a video from 1600*1200 to 1920*1080 ? I know that the aspect will be not correct, but I just like to do.

With Handbrake I can't do it, because it will not allow me to go beyond the 1600 pixels in the width.

Thanks for helping.

  • Are you ok with using a command-line tool?

  • Yes , would be happy to know. I guess you gave me already helped me with the ffmpeg tool to make a video faster. Can I do it with ffmpeg ? Thanks for helping. May 29, 2016 at 7:30

Using ffmpeg,

ffmpeg -i input.mp4 -vf "scale=1920:1080:flags=lanczos,setsar=1" output.mp4

This will stretch the video to 1920x1080.

ffmpeg -i input.mp4 -vf "scale=-1:1080:flags=lanczos,setsar=1,pad=1920:1080:(ow-iw)/2:(oh-ih)/2" output.mp4

This will keep the aspect ratio but place black bars on the left and right.

The flag in the scale filter determines the scaling algorithm to use. lanczos is the best available, in general, for video.

The setsar sets the pixel aspect ratio. Advisable to keep this square (1) unless you know what you're doing.

In the 2nd command, the -1 tells ffmpeg to preserve original proportion when scaling height to 1080. The pad fills out the canvas to 1920x1080 and centers the scaled video within it.
