So basically, you are instructing FFmpeg to rotate the video 90 degrees counter-clockwise two times which totals up to 180 degrees. You can see the result for yourself in the video below. I used the ParkJoy sequence and flipped it 180 using this command. How do you rotate a video 180° using the transpose command? ffmpeg -i inputVideo.mp4 -vf "transpose=dir=2:transpose=dir=2" rotatedVideo.mp4 0/cclock_flip = 90 degrees CounterCLockwise and Vertical Flip (default) 1/clock = 90 degrees Clockwise 2/clock = 90 degrees CounterClockwise 3/clock_flip = 90 degree Clockwise and Vertical Flip How to Rotate a Video 180° With FFmpeg? You can either mention a number from 0 – 4 or the words cclock_flip, clock, cclock, or clock_flip. To perform the 90-degree counterclockwise rotation, imagine rotating the entire quadrant one-quarter turn in a counterclockwise direction. In this example, you have to rotate Point C positive 90 degrees, which is a one quarter turn counterclockwise. Here are the options that are available in FFmpeg to rotate a video. Since 90 is positive, this will be a counterclockwise rotation. If you take the transpose of the matrix and then rotate the matrix row-wise along the mid row, you can get the same result as rotating the matrix by 90 degrees counter clock-wise. This takes a set of parameters to control the direction of the transpose/flip/rotate operation and to prevent the transpose from taking place. It makes the computation really simple and elegant. You are using the transpose filter using -vf in FFmpeg. If this rectangle is rotated 90 clockwise, find the vertices of the rotated figure and graph. ffmpeg -i inputVideo.mp4 -vf "transpose=dir=1" rotatedVideo.mp4 When we rotate a figure of 90 degrees clockwise, each point of the given figure has to be changed from (x, y) to (y, -x) and graph the rotated figure. Here is the command line for rotating a video using FFmpeg’s transpose filter.
