hi there

Is this possible with kdenline https://www.youtube.com/watch?v=z1V3Ssi4XOo

thanks

Yep. I would say everything he does here you can do in kdenlive.

Freeze the pic with
https://userbase.kde.org/Kdenlive/Manua ... ion/Freeze
or extract a frame
https://userbase.kde.org/Kdenlive/Manua ... ract_frame and use it as a clip.

You will need to do alpha manipulation using rotoscope see https://userbase.kde.org/Kdenlive/Manua ... nipulation and https://userbase.kde.org/Kdenlive/Manua ... otoscoping
