Avidemux Forum

Hi all,

I wanted to know if there is a way to rotate the preview video?

When capturing videos in portrait mode, avidemux shows / rotating them in landscape orientation.

Would be helpful that I can rotate the video to make it easier to watch the previews.

Of course, I understand that when exporting the video I will still need to configure the rotation separately.

If you set The Transform/Rotate filter to rotate the video, filter previews will display rotated.

If you click the button to the right of the Info button, below the menu bar (a green dot should appear to confirm on), main window playback will show rotation (though not when paused).

You can disable or delete the Rotate filter before exporting if desired.

Hi Sark,

Thank you for your reply.

However, I mean the main editing window still shows the video in landscape mode even after adding this rotation filter.

No. The feature is on the nice-to-have list.

Yes, by design, showing as coded and with square pixels, not applying any transformations either from container metadata or codec (except for crop directives from VUI, of course).

If you enable the button to the right of the info (i) button in the main window, you can playback with filter rotation applied.
Unfortunately, this only works during playback, so is not practical for frame by frame editing.

Thank you for your reply and I hope this nice-to-have feature will be implemented soon.

As I see more and more people use their phone to make video's. But maybe they use other video editors to edit their footage as opposed to me wanting to do that on a desktop pc.

Great tip! Didn't know about this feature.

However, as you stated it is not practical for frame by frame editing.

As of now I convert the videos with handbrake to portrait mode. It is annoying for needing to do an extra step and therefore decreasing the IQ of the original video but it is what it is.
