For anyone else not knowing what this is, Kdenlive is a Free and Open Source Video Editor. I’ve never used it but it looks like it has a lot of features.
Other than Krita (and Kdenlive) I have used all of those. I guess I’ve just never had the need for video editing. If I do in the future I know where to go first!
Yup, super quick to throw a cut together or some basic footage. It won't replace the full adobe suite, but if you want to cut basic videos together it's perfect
