Help, instructions to save filtered video don't work?
« on: March 21, 2017, 06:14:05 AM »
I just want to rotate the video.  This thread offers instructions that don't seem to work.

I have no trouble selecting the filter.  From there I only have the options to PREVIEW or CLOSE the window.  Preview is obviously just a preview.  Closing the window closes the window.  If I then check PLAY FILTERED then the video will play with the rotate filter active.  If I save the video I am left with an avi file that doesn't play.  The original format was mp4

Alternatively if I select "MP4 Muxer" under "output format" it will save as an MP4 file that plays but is not rotated.

Alternatively if I select "MP4 Muxer" under "output format" and then select "Mpeg 4 ASP(ff)" under "video output" then I get an MP4 that is rotated but the output is garbled.

What I need is a way to rotate the video and then save it so it will always play that way forever and is not garbled and doesn't have to be opened in special software.

and your source video is using perhaps vp9 video codec?
you're are using the latest avidemux ver 2.6.18? from where?
can you upload a max. 10 second footage of video you wish to rotate?
....

ps info: Upload Hochladen Télécharger Subir

Filter Transform Rotate
« Reply #2 on: March 21, 2017, 07:50:29 AM »
Just tested and seems to be working as it should.
uploaded 90° turned sample: Filter Transform: Rotate @ YouTube Avidemux Demo channel
Workflow:
with loaded video, select: Output Format: [MP4v2 Muxer]
Video Output: [Copy] -> [Mpeg4 AVC]
in [Filters] - [Transform]
Available Filters -> Rotate (double mouse click)
pop-up window: Angle: [None] -> [90 degrees] -> click [OK]

you should now see in Active Dilters
Rotate
Rotate by 90 degrees

right hand bottom: enable [v] Play filtered
play video, check if result is what you want
save video

ps.:
-  90° = anti-clock wise
- 180° = upside down
- 270° = clock wise

If you have OpenGl support enabled in avidemux, and your OS does support this.

Video Filter Manager: OpenGl: OpenGl Rotate
in pop-up window Angle (°): 45°
