I've used pretty much all amateur video-making software for Windows and some for Mac, Screenflow, FinalCut Pro, etc.
The best by far is FinalCut Pro (Mac-only), because it automatically creates proxy files and allows you to edit everything in real time with no lag, even when adding complicated effects.
The situation on Linux is dismal. The only good one is https://kdenlive.org/. It's actually I'd say at par to FinalCut in terms of performance, although the UI could use some clean up. It's the one I use because the other ones would either keep crashing, or be impossibly slow.
I wonder why (really, have no idea)?
Things Blender capable of for video:
* Advanced graphical node based compositing
* "Effects Strips": Essentially generates a strip in the sequence editor that you can layer above the target media strip. Like using a Photoshop layer for one specific effect.
* Decent audio mixing capabilities
* Fantastic motion tracking (advantage of being built into your creation suite)
Pro Tip: Make sure your output frame rate is the same as the videos you are going to import. Otherwise the audio gets out of sync.
I know on some (probably most) platforms you have to symlink some libs to make it run. Are you maybe just talking about that?
After that, it just crashes with an assertion. It seems that has to do with missing or wrong configs, but there's not much else to be found on google. My configs are present and look fine.
Also, only rpm based distributions are officially supported, but a lot of people hack around that to get it working on Ubuntu (like me).
It's proprietary and the free as in beer version is limited to 720p mp4 ("YouTube") export, which was sufficient for my use case.
The tool started to work on color, but it looks like they've made a decent editor also.
The content was super important stuff - early footage of many areas of the world not otherwise filmed - and was destined for Wikimedia Commons.
It was the worst experience I've ever had with commercial software since Windows 'corrected' an NTFS volume in ~2005 and nixxed the lot. From memory it was something to do with the input codec (beyond my control as lossless was a requirement), the output codec, and the aspect ratio. The software just couldn't cut the stuff. I was left to go back to ffmpeg and VLC. I will never again waste time learning a commercial UI.
It shines with large video asset databases, and once you get a few weeks of muscle memory behind it (or a few months if you're coming from FCP or FCPX), it's a fast tool when making lots of simple cuts. It has a well-earned reputation for cutting stuff like drama and comedy, where effects and pre-rendered sequences take a back seat to well-timed cuts between takes and fast iterative editing feedback. The node-based compositor is... unique, but I'm not sure I'm qualified to say it's an objectively easier or better workflow than AE — YMMV.
It's also capable of doing other things like handling basic A/V effects and compositing, but not as well as other NLEs or compositors. Its best output formats are behind a licensing wall, though they're still far cheaper than Adobe, Apple, or Avid, and you can do almost all your actual cutting with the free version. While it's more stable than some FOSS NLEs, it's still shakier than Avid or Premiere on well-supported hardware, with the distinct advantage that it's got native Linux support.
The weirdest part, though, was that it was supposed to have been open-sourced after EditShare acquired it, then they didn't, and they've been saying "it'll be open sourced when it's ready" for almost 4 years now.
Shotcut wouldn't keep working with XFCE4 Xubuntu 16.04 for me. If I applied any heavier effect it would freeze, then crash.
With even cell phones shooting 4k I would think this would be a standard feature. It's not super complex.
