You can do it manually in a video editor using keyframes, which you kinda have to do if there's any rotation, but it's a **** and takes ages.YouTube offers a deshaker stabilization too...This was done by manual rotation of the video, then a software deshaking....You can see how the frame rotates.

Are you sure about that? Your assuming that image stabilization process on the GOPRO, is exactly the same as the image stabilization program on the computer. I would have thought a camera would not pack as much processing ability as a PC, so it would make sence for the GOPRO stabilization on camera to be significantly less able , than what a full PC and software would offer.
Something like this stuff looks amazing.
www.wired.com/2014/08/killer-software-that-finally-stabilizes-shaky-gopro-videos/ I'm assuming so, but I have good reasons to do so. If you simply look at side-by-side video, you can see the stabilized ones are zoomed in. Pause it and see.
There are "physically" stabilized cameras, but I bet dollars to donuts that digital is cheaper and more robust.
This one says it's done with VirtualDub software and the Deshaker plug in, which has been around for years. It also requires very little processing power to run the software, although the more power you have the faster it does the job. Same problem that rendering video has always had. You have to mess with settings to get it working nicely, so it can be a bit fiddly and needs some knowledge of the software. The following was done by VDub & Deshaker.
en.wikipedia.org/wiki/File:Video_image_stabilization.ogv Same result, zoomed in when stabilized. So to answer the OP, you can do it before or after, but after is another step you have to do, although you get more control over it.
There have been stand alone "apps" that you just drop in the video and it does all the stabilization and color correction for you. The one I used for a while got bought out by the military for drones and public releases stopped :D
I seemed to remember Hyperlapse being developed in the noughties, but it's apparently only 2014. My poor memory. It's different to stabilization, in that it's a stabilized time-lapse, rather than real-time video. If your phone can do it (it's on Instagram) I don't think you need a lot of power for it either.
Gimbals are a different solution. You'd still might need to stabilize gimbled video if it's jerking up and down, like you'd see on the back of the MotoGP bikes...
