Just recently switched back to Linux after more than a decade away. (I'm currently running Mint Cinnamon if anyone is curious) On Windows I was using the free version of Davinci Resolve for all of my video editing. I quickly discovered that the free version of Resolve for Linux doesn't support H.264/H.265 so after trying every Linux video editor I could find (even Blender) I've settled on using Kdenlive. I've been having a good time getting everything dialed in and learning Kdenlive. I was able to get hardware acceleration working with my Nvidia GPU, and I really appreciated that it could natively utilize the proxy clips that my DJI Action 3 generates when recording. I've been reading all kinds of tips and tricks articles but most of it is just basic stuff. Anyone using Kdenlive have more advanced tips to share? Particularly anything around title generation and animation as I've found Kdenlive's system to be a little clunky. Let's talk!
I get what you mean - it's quite "roll your own" rather than "pre-made" - and the same for quite a few of the effects and motion settings.
Note that you can save template versions of effects or motion settings if you need, so after you've used it a while, you might have a reasonable library of things you need - but you're right, there's a bit of a lack of "drop in, ready to go", particularly for quick titles.
Something like a "jiggly funky colourful text shaking about" effect can be a day's work, rather than a 2 minute "write your own text with this pre-made sequence".
Just in case they're useful, there are a set of downloadable templates Kdenlive downloadable titles here, but I'm not sure it's quite going to cover what you're after - but worth a browse in case.
