Lens correction keyframe

Hey,
Would be nice to have keyframable lens correction in order to make sick glitch effects / transitions. :slight_smile:

Here’s a key framed version of the lens correction filter. Make a few glitch effects and transitions.

Copy the folder in the zip file to Shotcut\share\shotcut\qml\filters. It will show in the video filters list as Lens Correction Key Framed.

Thanks!
Is there by the way a filter for shearing?

Searched the mlt filters could not find anything for shearing. Do you have an example?

Kdenlive has a “Rotate and Shear” effect.

I looked at the Kdenlive UI for the Rotate and Shear effect. Seems it’s using the affine plugin.
That is way beyond my meager coding skills.:disappointed:

Ah, okay. I thought it was based in MLT.

Yes, but it not added yet because I have to make changes to MLT affine to support keyframes. I gate the addition of some things based on improving things in the lower software layers.

Looking at the Lens Correction filter again, I notice that the values are set as 1.000. Would it be better if it was updated to percentages like 100.0%?

Yes, I will address that.
