180 Mp4



Videos from phones often have metadata that tell the player to rotate upon playback (not all players respect this). When re-encoding, ffmpeg will automatically rotate the video according to the rotate metadata, so you don't have to do anything special:




180 mp4



Some videos, such as from iPhones, are not physically flipped, but contain video stream displaymatrix side data or rotate metadata. Some players ignore these metadata and some do not. Refer to ffmpeg console output to see if your input has such metadata:


Chroma subsampling. I included format=yuv420p since ffmpeg will attempt to minimize or avoid chroma subsampling (depending on the encoder, input, ffmpeg version, etc). This is good behavior in a purely technical sense, but most players are incompatible with more "advanced" chroma subsampling schemes. This is the same as using -pix_fmt yuv420, but is conveniently located in the filterchain.


Copy the audio. The -codec:a copy option will stream copy (re-mux) instead of encode. There is no reason to re-encode the audio if you just want to manipulate the video only (unless you want to convert to a different audio format). This will save time since encoding is time consuming and it will preserve the quality of the audio.


Older builds of ffmpeg do not include filtering capabilities. See the FFmpeg download page for several options including convenient builds for Linux, OS X, and Windows, or refer to the FFmpeg Wiki for step-by-step ffmpeg compile guides.


Following is a Bash script which will output the files with the directory structure under "fixedFiles". It transforms and rotates iOS videos and transcodes AVI files. The script relies on having installed both ExifTool and FFmpeg.


At the end you'll find the two consecutive FFmpeg commands that successfully rotated my video to the correct orientation. It seems to me the purpose of hflip and vflip in FFmpeg, is, at minimum, confusing, and contrary to what I expected.


I know I should've been able to mount my iPhone via USB and copiedthe files directly, but that didn't work; my laptop would recognizethe iPhone was connected, but it wouldn't mount its filesystem, andI got no prompt on my iPhone to "trust" the laptop.


The original file is Video 1920 x 1080 Codec HEVC/H.265 frame rate30/sec, bitrate 8140 kbit/s, Audio Codec MPEG-4 AAC audio ChannelsStereo, sample rate 44100 Hz, bitrate 85 kbit/s. When I play it onmy iPhone it's oriented properly, and the sound is synchronized.


The following inverted vertically so the playback is upright, synchronized the sound, and converted to MPEG-4, but it left thehorizontal incorrectly flipped end for end (this isn't a typo;I did specify 'hflip'):


The following two-step process finally got what I wanted; vertical andhorizontal both flipped, sound synchronized, and format converted toMPEG-4 (again, this isn't a typo; I used hflip in both commands):


Q 1: "I'm here to seek help for rotating an MP4 video file taken by iPhone 14 by 90 degree."Q 2: "Is there an easy-to-use tool to rotate an MP4 video by 90 degrees while keeping the video quality original? It doesn't have to be freeware."


How frustrated it would be when you recorded a precious MP4 video with your device but find it was in wrong orientation. Perhaps it was a vertical MP4 footage from your iPhone 14 Pro, which cannot be posted to the social platform that requires landscape orientation. Or maybe you started recording MP4 horizontally with your GoPro Hero 11 and wound up recording vertically.


Is there any way of fixing the wrong MP4 orientation? Yes, if you want to keep the MP4 video and view it properly, the only way is to rotate MP4 video and save it in right direction. Therefore, is there any way of doing this without losing the image quality? Find answer in this post.
