QT X was seen as a downgrade by pros (and prosumers) from the get-go. I just tried out 4 or 5 apps in the App Store and can't find any that can do a very simple cut, crop, rotate, trim functions quickly and easily. Basically, I need to take widescreen videos and do a quick vertical promo. I don't see anything out there. In the $20-$25 range, I'm finding the editors slow an ineffective. This should be a simple tool.
The process I just used: Trim in QT7Pro (faster than I would have in QTX), transfer to iPhone, Open the video in "Video Crop" on the iPhone (which is free - yup, that's the name of the app)...crop to 9:16 and expand in one simple step, then post via Instagram Stories. Great. It works. Why can't I do this in one simple app on the Mac. I should be able to do the Video Crop app functions right in Quicktime X. I should also be able to take advantage of the speech to text capabilities in Clips on a widescreen or vertical video...but that would be another thread.
iMovie and FCP is just overload for a simple edit. I don't want to deal with libraries, caches, etc for an edit that should take about 2 minutes total.
