AviDemux: Rotate Video Problem

[Leo48]

Trying to rotate videos (MOV, AVI) with AviDemux 2.4.1, I go Video -> Filters -> Rotate (x degrees) -> Close, then File -> Save -> Save Video (some filename), OK. The file gets saved in its original state, no rotation. Please advise on what I am missing.

Did you specify file name extension (e.g. "myfile.avi")

Is the rotate filter "Active" in the right hand side when you press filter?

Are you using the latest version of avidemux? (r3974)?

I see. They've hired you alright.

Yes, I did specify a valid filename with ext, and yes, the rotate filter is active in the right pane.
The packet has two exe's, ...gtk (german) and ...qt4. In gtk.exe the about dialog shows version r3971 , in qt4.exe the dialog does not open. This version is buggy I suppose? But this is what you get when following the links in videohelp.com (re-downloaded twice), where to get r3974?

Thank you for your patience.

Use the GTK+ version. Your build should be current enough, but here are the latest svn builds

If you toggle the view in the drop down menu at the top to "output" or "side" instead of "input" do you see the rotated preview?

What did you set for the video, audio and format container?

@Midzuki - yes I guess I should have used a different frame (I'm not an evil spy hired by you-know-who to infiltrate the masses of videohelp)

Ah, this is the stupid guy's problem. I did not set anything, so it's copy, copy, avi.
What I should select depends on
- what the source permits
- what I intend to do with it, I suppose?
In this respect, some newbie hints would be much appreciated.

For basic settings try MPEG-4 ASP (Xvid4) for the video sidebar, MP3 (Lame) for the audio, AVI for the format. Add your rotate filter. You can preview it before saving if you toggle "output" instead of "input." Press save with extension (e.g. "myfile.avi")

You can adjust bitrate, quality, edit etc...If you provide more information on what you want to do with it, I'm sure people here can help.

Some videos pass well, but unfortunately, I get lots of errors. Admittedly, I have source files of rather widespread quality and size, from several cameras.

- saved file cannot be opened
- a crash protocol has been discovered
- saved videos have the colors inverted (blue -> yellow etc.)
- encoder initialization failed
- error initializing the audiofilters

Trial and error is rather limited fun. There are no articles/help files?

At the moment, I have a bunch of AVIs and MOVs (Olympus digicam), some have to be rotated, and I would like to make DVDs for standalone players.

Leo48, go to Video > Filters, then click on the Colors button on the left side of the window. Add the Swap U and V filter, then click Close. Now the colors should be correct in the rotated video file.

I've followed the same steps as you and also have errors in the rotated file. When I try to play the video in Windows Media Player, it just sits there doing nothing. I am able to play the rotated video in Media Player Classic though without any errors.

Leo48 - If you want the "expert" way of doing this that should work for virtually everything, you will have to learn how to use avisynth and scripting to do your transformation(s).

Feed the .avs into a MPEG-2 encoder (like HCenc or CCE) to generate a DVD compliant video stream which then can be authored by an authoring program.

I don't think there are guides to do exactly what you are asking, but if you search there are general guides around for each step.

Good luck

I'm sorry for the kick, but I'm encountering the exact same problem...

In my case I want to rotate an MPEG-4 video with AAC audio in an MP4 container by 90º clockwise. It's a mobile phone video so I don't want to fiddle with compression to avoid quality loss... Doesn't Avidemux support this action? The colors aren't distorted, but the output video remains the same - although the output preview shows it correctly...

I just downloaded the latest version of avidemux for OS X PPC (v. 3.4.4) in the GTK version.

You can not SAVE AS and retain the rotation without re-compression
