How To Rotate a Video - step-by-step

Not implemented.

Thanks to OP.

In the version I have (2.0.3) It is under Video Effects:

Control+E (or Tools -> Effects & Filters)
Video Effects Tab
Geometry Tab
Check the transform for exact rotation or the rotation box and you can manually rotate.

Enjoy.

I have a number of avi videos which I wish to rotate by 90 degrees.

Ideally I want to use the command line to permanently save a file with no alteration except a rotation
I've tried command lines with both -video-filter and -vout-filter:
"C:\Program Files\VideoLAN\VLC\VLC.exe" --vout-filter=transform --transform-type=90 "20120709-122536 - IMGP2831.AVI" --sout=test.AVI
"C:\Program Files\VideoLAN\VLC\VLC.exe" --video-filter=transform --transform-type=90 "20120709-122536 - IMGP2831.AVI" --sout=test.AVI
With both these, the file is output totally unchanged (ie no rotation). Other transform-type options (90,180,270,hflip,vflip) also have no effect.
Both versions produce a file exactly the same as the input file (ie no rotation)

I don't want to do with the GUI as I want a permanant modification to the file, but thought this might at least allow me to play the files, but I am having problems here too.
If I use the GUI and select tools/effects/video/geometry/transform (rotate 90) it rotates it, but instead of being tall and narrow the image is fat and wide (ie takes up exactly the same size on the screen) with 2.0.4 and very narrow and tall (cropping the sides) in 2.0.5. For both versions the image is largely grey-scale with some of the colours smeared horizontally.
If I use the GUI and select tools/effects/video/geometry/rotate (and set dial to 90) it rotates it correctly (ie aspect ratio and colors are OK), but crops it so the height is the same as the original file, thus chopping off the top and bottom of the view.

I've tested this in both VLC 2.0.4 and 2.0.5 under XP, and neither work properly. I've also tried a couple of different output codecs and deinterlace modes, which seems to make no difference to the output.

Can anyone help, especially with the correct command-line syntax to get the view rotated with no cropping.
I don't really want to install another program, but perhaps if anyone knows of a tool which can do the job could use that instead. I've tried:-
MEncoder does the best job with: mencoder "20120709-122536 - IMGP2831.AVI" -o output.avi -vf rotate=1 -oac copy -ovc lavc -lavcopts vcodec=mjpeg
But vlc playback has little lines which weren't present in the original.
MJPEG Lossless Rotate (http://mjpeglossless.sourceforge.net/) rotates correctly and apparently without re-encoding, but suffers lines in playback (and isn't command line).
DVDVideoSoft has a free tool which rotates the video correctly, but also decreases the quality (and isn't command line), so no good.

Just wondering - the lines aren't present in other players, but do seem to occur with a variety of codecs under VLC, so perhaps is a bug with VLC. Perhaps someone has suggestions on how to get rid of them instead.
Thanks

I don't usually participate in forums like this, but after finally discovering how to rotate a video in VLC Media Player I decided to post the CORRECT method so that you won't waste your time with all of the other INCORRECT posts. If you follow these instructions EXACTLY you will be able to easily rotate your video:

1. Open video with VLC Media Player
2. Right click on the video while playing
3. Left click ‘Tools – Effects and Filters’
4. Left click ‘Video Effects’
5. Left click ‘Geometry’
6. Check ‘Transform’ box
7. Select ‘Rotate by XX degrees’
8. Left click ‘Close’ button

Voilà! No need to thank me.

Please help, I did exactly as per instructions (except I checked the rotate box as well, but have now unchecked it ) and now when I play a vedio it has sound but just a black screen, I know its probably something simple dut I dare not do anything in case I make it worse. Any help greatly appreciated.

[alpinestars69]

your instructions are very different from what i am seeing,

----With the video open, go to "Window" > Extended Controls.
- In the EX popup, select "Video Filter" from the drop down. Then check "Transformation".
- The video will close.
- Re-open the video file. It should be rotated. If it's not rotated correctly, go back to Preferences and adjust the degree of rotation---

^^^ all of this part was no where to be found anywhere...

oh no i am going to thank you, thank you very much because i find it far & few when you can get an answer & a correct answer on this forum, very frustrated with vlc & just trying to understand it, the rotated videos in my library are now fixed, to thank you thank you !!! any idea how they got rotated to begin with..

My video was flipped by 90* and because of the bug mentioned above, the movie was running correctly on VLC app. I just exported that video to actually covert by 90*.

The following instructions are for the VLC on mac.

1) File -> Streaming/Export Wizard
2) Transcode/Save to File
3) Select video to convert from Playlist(You should have played the file atleast once.
4) Next
5) Select MOV format
6) Select a filename ending with .mov extension
7) Next and finish

VLC will save the new flipped video which is ready to playback on Quicktime player.

Put the movie(s) into Picasa. Picasa lets you rotate them with the click of a button. If you export the rotated movies, they are actually rotated in the new files and will appear rotated when viewed in quicktime or VLC.
