Unfortunately (because proprietary), Davinci Resolve is the best option I think. I’ve been looking to get away from After Effects and Premiere. The only possible, performant and reliable solution I found is the free version of Resolve. Tested Kdenlive a while ago but it crashed two times in the first 20 minutes so I gave up because I had a deadline. I’m always trying to give Open Source a go over proprietary.
I’m not a big fan of the UI/UX of Resolve though, took me a few days to get up and running for my basic needs but it did the job.
Olive will be a huge game changer I think/hope. Been supporting it since I first heard of it and the playback speed was crazy fast compared to AE/PR at that time on my machine at work.
I edited/cut this with Olive Version 01 a while ago (we needed multiple formats for Instagram, Facebook etc.), not a biggie and most things came straight out of Blender anyway, but the timeline speed is awesome. https://www.youtube.com/watch?v=q2QaeatlWvY Olive is just awesome, but it needs time to mature.
The free version of Davinci Resolve now has Fusion nodes, yes. Pretty powerful for color grading and the like, there are just a few nodes that are only in the paid version but you can work with it pretty well, even let’s you create 4k material. I only made the skulls intro (00.15-00.30min), heavy color grading, sharpening and all those things. You need a somewhat capable GPU but apart from that it is really flexible. https://www.youtube.com/watch?v=_izvgFh4uhY
Natron is completely node based and “like” Nuke but FOSS, but it is maintained by only one person afaik and I couldn’t get it to run without constant crashes. Crashes can of course always be my own fault.
Also tried Hitfilm Express, they also have a free version and it looks pretty much like AE, works really well for basic things.
