invalid frame size while using ffmpeg

Question

I am trying scale and convert a video:

ffmpeg -i input.mkv -s 1920×1080 output.mp4

But every time it shows error (Windows):

Inv         


        

Answer 1

Also, it cannot be a double, eg 512.0. Make sure it's an int 512.

Answer 2

Use x, not ×.

• Incorrect: 1920×1080
• Correct: 1920x1080
