It lacks a lot more than flashy social media features - and given their biggest driver in the 2010’s was arguably YouTubers, they actually need more robust social media features. For starters, they just added voice isolation what? A year ago? That has been bog-standard for resolve and premiere for years now. The audio tools in general are still very subpar.
I used it professionally from 2011-2020 or so. Around 2020 the gaps in feature parity became wider and more apparent, it’s clearly not a priority anymore. Once I went to resolve I basically abandoned it. I use maybe every 6mo tops now for quick stuff for friends and family or to open an old project.
The one thing I will say is for speed cutting, it’s probably the best. And that’s no small thing! But that’s about it.
It's certainly interesting that Apple have been pushing Blackmagic's products. They practically rely on Blackmagic software for all their demos when they release some new bit of hardware. They totally conceded on the camera app, for instance.
That has always been an issue. Pros buy Apple hardware but very rarely commit to Apple software.
In my experience, they are perfectly right. Not only can Apple not be trusted to maintain the software to be competitive feature-wise, but they are also very likely to get bored or make some annoying hardware requirement that makes fleet management annoying.
In the end, their creative software is just ok; it's probably best to not rely on it too much if you don't want to get stuck.
After they canceled Aperture for no good reason and destroyed the iWork suite while taking forever to even manage feature parity, I'll never rely on or recommend Apple software.
It lacks some flashy social media features and modern conveniences for sure, but it's still a very good and widely used editor.
