Hi all,

Nice. This is an effect I wanted to use in near future. Thank you for sharing.

After upgrading to 0.8.2.1 I can't find this effect anymore ...
where's DISTORT - CORNER ?
Anybody can find it ?
oh God....

I'm using Kdenlive 8.3 and they are both in the Effects list under the heading "Distort".

Thanks God...
after removing, installing and updating again...
I found it again !!!!...
