FFmpeg is a free and open-source set of programs and libraries. It is specially created for processing multimedia files. It has many applications, and one of them is rotating a video. You can rotate any video using FFmpeg irrespective of the size and format. In this article, we will have a look at FFmpeg rotate video feature. We will discuss the step-by-step procedure to rotate a video using FFmpeg. We will also introduce some better alternatives.
Part 1. Rotate Videos Using FFmpeg from Command Line
If you need to split video in FFmpeg, you need learn how to use the command, it is very hard for some beginners if they dont know how to use the command. i would recommend iMyFone Filme for FFmpeg alternative. iMyFone Filme can split video with few clicks in 5 seconds. Download iMyFone Filme now.
FFmpeg can be used to rotate your videos. You only need a single command for it. You can follow the given steps to rotate any video using FFmpeg.
Step 1: First, you need to download FFmpeg. You can search on Google and download it for your computer. Then, set it up and make sure it is working fine. Open the command line and type "ffmpeg", if it works, you can go to the next step.
Step 2: Now, you need to go to the directory/folder where you have stored the video file. You can use the following command.
You need to copy the path of the file and replace it in the above command. Enter the command and hit Enter.
Step 3: You can rotate the video using the following command,
ffmpeg -i input.mp4 -vf "transpose=1" output.mp4
In the above command, you need to replace "input" with the original file name and "output" with the name that you want for the output file. Make sure to enter the right extension of the input file. If it is MOV, then you need to write it instead of MP4. You don't need to match the extension of the output file; it can be the same or anything else. It means you can also convert the file at the same time.
Another important thing is the value of "transpose". The rotation of the video depends on its value.
0 = 90° rotation anti-clockwise and vertical flip
1 = 90° rotation clockwise
2 = 90° rotation anti-clockwise
3 = 90° rotation clockwise and vertical flip
There is no command for 180° or 270° rotation, but you can do it. You can use the transpose command multiple times. You can use the followings,
For 180° = =transpose=1,transpose=1"
For 270° = =transpose=1,transpose=1,transpose=1"
Thus, the command for 270° would be like,
ffmpeg -i input.mp4 -vf " transpose=1,transpose=1,transpose=1" output.mp4
Step 4: After writing the command, hit enter. Wait for a few minutes, and your file will be ready. Check the file location and see the video.
Part 2. FFmpeg Can't Rotate Video? Solved
Problem 1: Can't get rotation metadata removed from video file in FFmpeg
Sometimes the rotation information is stored in the metadata. Thus, after the rotation of the video, it can easily be detected that the video was rotated. If you use such a video on YouTube, any software program, or any other platform, it will detect the rotation and show it. The metadata depends on the command you have used. The command that we have discussed does not retain the rotation in metadata, so you can use it without any hassle. It works perfectly well.
ffmpeg -i input.mp4 -vf "transpose=1" output.mp4
Problem 2: FFmpeg rotate 90 degree on Windows not working
There can be issues with some commands on Windows. So, you might not get the desired or expected results. However, the following command works perfectly well on Windows.
ffmpeg -i input.mp4 -vf "transpose=1" output.mp4
The command will rotate the video by 90° in the clockwise direction. For anti-clockwise, you need to set transpose=2.
Problem 3: The rotated file audio does not sync with video in FFmpeg?
If the audio is not synced, you need to use "setpts". It is a filter that changes the presentation timestamp of input frames. It could help you match the audio with the video. You can use the following line of command.
The above command will apply an offset of 10 seconds to input the presentation timestep. You can change the value "10" to any value you want.
Problem 4: FFmpeg is not recognized
You might get an error that FFmpeg is not recognized as an internal or external command. This usually happens when you forget to add the path of the exe files in the environment variables. Go to Control Panel>System>Advanced System Settings. Click on Environment Variables. You will see the Path variable. Select it and click on Edit. Click on New and paste the location of the bin folder of FFmpeg that contains all the exe files. You are ready to use FFmpeg on the command line.
Part 3. Pros and Cons of Using FFmpeg to Rotate Video
There are several pros and cons of using FFmpeg to rotate a video. Let's have a look at them.
Single Line of Command:
You only need a single line of code to rotate the video. Thus, if you know the code, you can rotate the video in no time. The command only requires the input and output file name, and the rest will be done by the program. It hardly takes a few seconds to rotate the video and create the final file.
You can also change the video format while rotating the video. Whatever video format you need, just enter it after the name of the output file. The video conversion will be done while rotating the video. The best thing about it is that it supports all formats.
