| ====== Ubuntu - Video - ffmpeg - Rotate Videos ====== | |
| |
| ===== Software Encoding ===== | |
| |
| <code bash> | |
| ffmpeg -i in.mov -vf "transpose=1" out.mov | |
| </code> | |
| |
| <WRAP info> | |
| **NOTE:** 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.264 encoding guide if you want VBR options. | |
| |
| |
| For the transpose parameter you can pass: | |
| |
| * 0 = 90CounterCLockwise and Vertical Flip (default) | |
| * 1 = 90Clockwise | |
| * 2 = 90CounterClockwise | |
| * 3 = 90Clockwise and Vertical Flip | |
| |
| Use **-vf "transpose=2,transpose=2"** for 180 degrees. | |
| |
| </WRAP> | |

| ---- | |
| |
| 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: | |
| |
| <code bash> | |
| ffmpeg -i input.m4v -metadata:s:v rotate="90" -codec copy output.m4v | |
| </code> | |
| |
| Check the rotate metadata first with: | |
| |
| <code bash> | |
| ffmpeg -i input.m4v 2>&1 | grep rotate | |
| </code> | |
| |
| ---- | |
| |
| To rotate the picture clockwise you can use the rotate filter, indicating a positive angle in radians. With 90 degrees equating with PI/2, you can do it like so: | |
| |
| <code bash> | |
| ffmpeg -i in.mp4 -vf "rotate=PI/2" out.mp4 | |
| </code> | |
| |
| for counter-clockwise the angle must be negative | |
| |
| <code bash> | |
| ffmpeg -i in.mp4 -vf "rotate=-PI/2" out.mp4 | |
| </code> | |
| |
| |
| It is possible to get finer-grained resolution of radians, because * behaves as multiplication: | |
| |
| <code bash> | |
| ffmpeg -i in.avi -vf "rotate=-8*PI/40" -q 1 out.avi | |
| </code> | |
| |
| (slightly less rotation than -PI/4 = -10*PI/40 | |
| |
