Where have the rotate options gone? Make sure you use a recent ffmpeg version from here a static build will work fine. Note that this will re-encode the audio and video parts. You can usually copy the audio without touching it, by using -c:a copy. To change the video quality, set the bitrate for example with -b:v 1M or have a look at the H. A solution is also to use this convenience script.
Can HandBrake flip/rotate a video? - Super User
If you don't want to re-encode your video AND your player can handle rotation metadata you can just change the rotation in the metadata using ffmpeg:. Have you tried transpose yet? Like from the other answer.
If you are using an old version, you have to update ffmpeg if you want to use the transpose feature, as it was added in October The FFmpeg download page offers static builds that you can directly execute without having to compile them. I came across this page while searching for the same answer. It is now six months since this was originally asked and the builds have been updated many times since then. However, I wanted to add an answer for anyone else that comes across here looking for this information.
The key being that you are not to use a degree variable, but a predefined setting variable from the MAN page. To rotate the picture clockwise you can use the rotate filter, indicating a positive angle in radians. The transpose filter will work equally well for 90 degrees, but for other angles this is a faster or only choice. If you're getting a "Codec is experimental but experimental codecs are not enabled" error use this :.

Rotating a Single Photo by 90 Degrees in the Library Module
I am wondering, if this can be achieved without decoding and then re-encoding the video -- the way jpegtran can losslessly rotate JPEG images Dec 31 '13 at See here for rotation flag: stackoverflow. Even though I can play back the rotated video, it was rejected by vimeo. OrangeDog's approach -vf "vflip,hflip" works like a charm. Rotate 90 clockwise: ffmpeg -i in. Alexy Alexy 6, 1 1 gold badge 10 10 silver badges 2 2 bronze badges. The video will still have the orientation information so now the video will be miss corrected on the iphone.
When I use this command, I get a low quality video output , unless -- as I've just discovered -- I use this parameter as well: -vcodec libx But it would be great if I didn't need to look up which encoding to use as ffmpeg should already know it. Any suggestions? Along the same lines as Sadi, is there a way to "copy" the quality of the original video?

Current docs note that "Numerical values are deprecated, and should be dropped in favor of symbolic constants. If you don't want to re-encode your video AND your player can handle rotation metadata you can just change the rotation in the metadata using ffmpeg: ffmpeg -i input.

This is the best answer by far. But there is a small improvement to do. To avoid loosing the remaining meta-data such as date, camera on the video do ffmpeg -i input. This way all global metadata on the input file will be copied as global metadata to output file and only the rotation meta-data is changed. Is that supposed to work? IMHO best solution because no reencoding is necessary and most video player support metadata rotation. Also Cloud services like Google Photos. However, remember that ffmpeg does not necessarily copy all metadata from the original file!
Therefore, I would recommend to explicitly specify to copy all other metadata from original file: ffmpeg -i input. No, I have not. I didn't know it existed.
I'll give that a shot. Well, I was surprised to find that this happens quite often, especially when you think about cell phone cameras, flip cams, digital cameras, etc All of these devices are just begging to be held sideways when recording video.
