how to rotate video without loss? - ssdde - 01.08.2021 rotate 90°, and keep quality without encoding. RE: how to rotate video without loss? - Selur - 01.08.2021 Rotating a video without reencoding isn't supported in Hybrid. If your output is mp4 or mov: ffmpeg -i "path to input" -map_metadata 0 -metadata:s:v rotate="90" -codec copy "Path to output .mp4/.mpv" allows to rotate a video by setting some meta data for the player, so that the player will rotate on playback. Something similar can be done for mkv using mkvmerge and the projecttion options: --projection-type TID:method      Sets the video projection method used. Valid values are 0 (rectangular projection), 1 (equirectangular projection), 2 (cubemap projection) and 3 (mesh projection). --projection-private TID:data      Sets private data that only applies to a specific projection. Data must be given as hex numbers with or without the "0x" prefix, with or without spaces. --projection-pose-yaw TID:float      Specifies a yaw rotation to the projection. --projection-pose-pitch TID:float      Specifies a pitch rotation to the projection. --projection-pose-roll TID:float Specifies a roll rotation to the projection. see: https://mkvtoolnix.download/doc/mkvmerge.html Cu Selur
