Update value of Rotation in mov file using Exiftool

Question

Phil Harvey has provided some excellent examples for using Exiftool to write photo metadata at https://exiftool.org/exiftool_pod.html#WRITING-EXAMPLES. Following Phil's examples, I've had no problem updating existing metadata fields of JPGs. However, I'm now trying to apply to same logic to video metadata (MOV wrapped H.264) but am not having any success. I've got a video that is upside down according to the iPhone 5 (iOS 7.1) it was shot with - the rotation value is 180 instead of 0. So I'm executing "exiftool -Rotation=0 [file name]" but the result I'm getting is: 0 image files updated 1 image files unchanged Is there something fundamentally different with video metadata? Could this be a permissions issue? Is my execute statement incorrect? Is there perhaps a better approach? Thank you! Update as of July 10: According to the Exiftool website again at https://exiftool.org/TagNames/Composite.html, I found that the Rotation field cannot be edited: Tag Name: Rotation Writable: N Derived…

Accepted Answer

You can use the latest Exiftool to rotate the MOV.

https://exiftool.org/

```
exiftool -Rotation=0 *.mov 
```

​ Please refer the table below to set the rotation. It will apply the values in the Track1 of the QuickTime MOV.

MatrixStructure 0 1 0 -1 0 0 1080 0 1

Vertical, Home button is down, Rotation=90

MatrixStructure 1 0 0 0 1 0 0 0 1

Horizontal, Home button is right, Rotation=0

MatrixStructure 0 -1 0 1 0 0 0 1920 1

Vertical, Home button is up, Rotation=270

MatrixStructure -1 0 0 0 -1 0 1920 1080 1

Horizontal, Home button is left, Rotation=180
