This is my (controversial) tip: ask an LLM. It works wonderfully for these cases. “Give me an ffmpeg command that cuts the last X seconds of a video in a lossless manner, stabilizes it and speeds it up 200%”.
You can then checkout those commands on the manual/online to verify.
As a KDE fan, I don’t use any of these “redundant” programs, unless there is a true benefit.
The thing is that, LibreOffice works and looks great in Plasma, and Calligra doesn’t do anything special.
It’s even more obvious for me with KTorrent. We already have qBitTorrent!
I absolutely like things like Neochat, tho, because in this case the “official” alternative is an annoying Electron app.
In Arch Linux, you get the new Kdenlive version days before the official blogpost, 😅.
I use Arch, BTW.
