This is particularly true for ABR video streaming where a single video is taken as the source and compressed to several different bitrate-resolution combinations. In this FFmpeg tutorial, we learn to change the resolution of a video (or resize/scale a video) using FFmpeg’s commandline tool.Ĭhanging a video’s resolution (also known as resizing or scaling) is a very common operation in video editing, processing, and compression.

So you could type: ffmpeg -i in.mp4 -vf scale=720:-2 out.mp4
Actually, -2 is a better choice since the computed value should even. You can set the width or height to -1 in order to let ffmpeg resize the video keeping the aspect ratio. With a reasonably recent ffmpeg, you can resize your video with these options: ffmpeg -i in.mp4 -vf scale=720:480 out.mp4 I’m no ffmpeg guru, but this should do the trick.įirst of all, you can get the size of input video like this: ffprobe -v error -of flat=s=_ -select_streams v:0 -show_entries stream=height,width in.mp4
