It's been a few decades since I got into it, but can you tell me the best Linux alternatives to Adobe Premiere / After Effects, Final Cut Pro, and AVID? I've tried a few and they tend to have problems with crashing and overall limited functionality.
Probably the best alternative to Premier is KdenLive or DaVinci.
As for After Effects, I'm not too sure. The alternatives definitely exist, I'm just not sure which one to recommend. It's been years since I've done any compositing. But I use KdenLive for video editing regularly and it's great.
In fact, the past year of development has been monumental in the amount of improvements and new features.
Man resolve is soooo good, UI is awesome,live saves are black magic, fusion page is straight up God sent and is fuck ton faster than Adobe suit. And not to mention one time purchase.
Resolve unfortunately isn't FOSS but the free version is quite fully featured and the full version is pay-once and not that expensive (also free with some of the Blackmagic hardware like their cameras I think).
