Hello,

I have a video in 1080p 30fps profile with images and most of the transitions are composite. When an image is moved vertically the movement is smooth and nice in rendered file, but when there is a diagnola movement one can clearly see the up and right, up and right, ... movement. Like a stair function.

Can I avoid this?

Thank you very much!

No, sorry. This is a known limitation of the Composite.

Hm. Could I switch to a very high framerate like 90fps and after rendering the movie, transcode it to 30fps? Could I do the transcoding with kdenlive or would I need something like Handbrake?

Hehe. No, that would not work. I assume the problem is that Composite only supports full pixel movements. Moving images by half a pixel to the right is slightly more complicated.

What you could try to do is using a project with twice the original size and scale the rendered video back to original size. But that is not very cool to do ;)

To me this is something very basic. I am a bit surprised, that it is not shipped with such a full featured video editor. Do you plan to add this feature?

"shipped?" Uh, well, this is not even version 1.0 yet if that is any consolation. :-/

If you are using mlt v0.5.6, you can use the Affine transition (without the rotation and shear), which does interpolation and is a little better.

OK, "shipped" is the wrong word. Thanks for the hint. I will try that.
