While playing around with the new Transform effect I noticed these two shortcomings: 1. As the angle of rotation is limited to 0...+360° it is only possible to rotate CW. For static compositing this is fine, but when using keyframes it might be necessary to rotate CCW instead. So please add support for rotation from -360°...+360° as, for instance, Affine does. 2. The origin of rotation is the upper left corner. However, I would expect this to be the center of the image, where also the cross marker for moving the frame is located. Please support rotation along the center axis. Reproducible: Always
3. Can the alpha operation parameter be used at all for a filter/effect?
Agree with all suggestions.
Yes, please! Go to the easy fast fix, moving the origin of the rotation to the center of the image instead of 0,0 This is oneliner fix :) (Maybe more if you have to migrate old .kdenlive after the change..) Or the complex one, allow to put set the origin of the rotation
The workaround for this one is to use affine After trying everything, affine is the only one that keeps everything good about transform (rotation, keyframes, scaling) and its able to rotate using the center of the image
The affine transition is not necessarilya substitute for composite&transform, or the transform effect: affine uses "atop" compositing, which often yields undesired results when working with multiple layers of transparency. Instead, often "over" compositing is desired. For details on how affine/atop and transform/over differ, please see our toolbox article "compositing with transparency", https://kdenlive.org/project/compositing-with-transparency/.
Hello, both CCW rotation and rotate from center options are available since latest release. Closing, but if you encounter any issues don't hesitate to reopen.
