It makes people WANT to watch your video. A good thumbnail image highlights the content of your video and makes it stands out. So, if the video orientation didn't work, you may need to re-encode it as shown in the first command.A video thumbnail is a still image that acts as the preview image for your video. But it worked in Gnome media player! I don't know why. But it kept playing the video in the previous orientation. I changed the video orientation in metadata only and played it in Smplayer. Please note that it doesn't work in some players that can't handle rotation metadata. $ ffmpeg -i input.mp4 -map_metadata 0 -metadata:s:v rotate="90" -codec copy output.mp4 If you don't want to re-encode the video and change the rotation in the metadata only, use this command instead: $ ffmpeg -i input.mp4 -c copy -metadata:s:v:0 rotate=90 output.mp4Įven better, you can copy all the global metadata (such as date, camera details) of the input file to output file like below. The above commands will re-encode audio and video parts of the given video file. $ ffmpeg -i input.mp4 -vf "transpose=2,transpose=2" output.mp4 To rotate videos by 180 degrees clockwise, you to need to mention transpose parameter two times like below. 3 - Rotate by 90 degrees clockwise and flip vertically. ![]()
