Lens correction keyframe

dailylolrecap · July 25, 2019, 1:33pm

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

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, I plan to include this in the next version 19.08

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.

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.
