I'd like to use HandBrake to compress some video that was taken via a camera that was mounted upside down.
I found a reference to a command-line
rotate option, but I can't find it in the GUI.
Am I just missing it?
On the Extra Options under Video tab put
, --rotate=4 to rotate clockwise by 90 or
, --rotate=7 for 90 counterclockwise.
Note: It will not work without the preceding comma and space.
(As of version 0.10.2.7286)
----Edit: as of 0.10.5.x
90 degrees counterclockwise
90 degrees clockwise
From the Handbrake documentation:
--rotate Flips images axes <M> (default 3)
To rotate 90° I used:
HandBrakeCLI -i source -o target.m4v --preset="Universal" --rotate="4"
with success. No luck getting this to work from the GUI.
note: I'm not sure why the above referenced blog post says:
a value of 1 flips on X, 2 flips on Y, and 3 flips on X and Y.
"3" is said to be default and as such should do no rotation at all. I've found this to be true.
info added by sorein:
HandBrake documentation: https://trac.handbrake.fr/wiki/CLIGuide
(comma and space needed)
It has to be entered in the tab VIDEO / EXTRA OPTIONS
Behaviour of "n"
The management of the ROTATE option is chaotic. It mixes FLIP and ROTATE!
1 : x flip
2 : y flip
3 : 180 degrees rotate (also the DEFAULT)
4 : 90 degrees rotate (clockwise)
5 : 90 degrees rotate + y flip
6 : 270 degrees rotate + y flip
7 : 270 degrees rotate
From a recent post iPhone video rotation (and compression)
HandBrake (or at least the GUI) does not offer a way to rotate video. The HandBrake CLI does have a "rotate" option, however I found it is not a true rotation. Rather, it simply flips on an axis. The documentation is poor, but I found that a value of 1 flips on X, 2 flips on Y, and 3 flips on X and Y. So using a value of 3 is the same as doing a 180° rotation, which is useful for videos that are upside down, but not for videos that are sideways.
mencoder can do proper rotation.
While this refers to a Mac OS-X platform, I guess it should work for you too. Find a mencoder binary for your platform.
Fill disclosure: VidCoder author here.
An alternative might be to use the latest VidCoder beta, which uses the HandBrake engine and has in-GUI support for rotation and reflection (with previews):
I've tried putting
-7 --rotate <3>
into the box in the Video tab under Optimise Video: Extra Options box.
It worked and flipped my video on the XY axis (180 degree rotation).
In Winx64 0.9.9.5530 the syntax is:
No leading or trailing comma, space, etc.
