91.19 Video Rotate


A video can be rotated clockwise or counter clockwise easily with ffmpeg. Here, the input video is identified using -i. Video filtering is introduced with -vf as a shorthand for -filter:v. A transpose=1 will rotate the video clockwise. The audio is kept as it is with -c:a. The video is copied to the output video file.

$ ffmpeg -i input.mp4 -vf transpose=1 -c:a copy OUTPUT.mp4

A counterclockwise rotation is achieved by a transpose=2 filter.

$ ffmpeg -i input.mp4 -vf vflip -c:a copy OUTPUT.mp4
