using ffmpeg to rotate or flip your video
ffmpeg -i input.MOV -vf "transpose=0" transpose0.MOV
ffmpeg -i input.MOV -vf "transpose=1" transpose1.MOV
ffmpeg -i input.MOV -vf "transpose=2" transpose2.MOV
ffmpeg -i input.MOV -vf "transpose=3" transpose3.MOV
ffmpeg -i input.MOV -vf "vflip" verticalflip.MOV
ffmpeg -i input.MOV -vf "hflip" horizontalflip.MOV
these commands are used when:
ffmpeg is free and opensource. if you take a video sideways on your cell phone and want to rotate it you can use the transpose command. This video shows you the different ways that transpose works so that you can rotate and flip the image.
Also, when you use your cell phone to take videos they can be a mirror image so if you want some signage in your photo to look as it does in real life then you need to flip the image horizontally or vertically using hflip or vflip and I show that command in the video.
hope this is helpful. have a nice day :)
