Evening, gang.
Now then; I've got a treat for those budding film-makers among y'all. A 'portable' version of the grand-daddy of non-linear video editors, and the one that kicked the whole genre off wayyy back in 1989:-
Lightworks
This is to all intents and purposes paid, proprietary software.....except it's possible to run a 'permanent', free trial. More on this in a moment.
I've been hum-ing & haa-ing about this for quite some time now. Many folks reckoned it was Windows-only, quite a few said they always used the online version, but a handful were saying it IS available for Linux although a PITA to figure the download out. They were bang on the money with that last statement, an' all; the perpetually self-renewing 90-day free trial is obscured to the nth degree, and I ended up getting instructions from a video-site's blog on how to read & use the website!
I'm pretty good at figuring this stuff out normally, but without a nudge in the right direction, I would never have found it if left to my own devices. Talk about hiding in plain sight. It was there in front of me all the time, but completely camouflaged. Of course, they'd rather you stumped-up for the expensive SAAS permanent monthly subscription, wouldn't they?
Getting this working has more than made up for my disappointment in not being able to get DaVinci Resolve operational... 
I could have installed the .deb, then figured-out the necessary steps for creating the portable from that, but I decided to be clever, and figure it all out directly from the contents of the extracted .deb package. Which took a bit longer, and involved not only a dedicated launcher but also a substantially-modified version of their own 'wrapper script'.....eventually combining the two together for maximum effect (after I'd finally sussed out the right order & locations for everything)..! 
This will run OK in Fossapup64 and Bionicpup64.....also the new KLV 'Airedale'. As expected, anything older than that, and you'll be whistling Dixie; glibc 2.27 or higher is required.
You'll need to visit the Lightworks website & register for a free account. This is necessary, because you want these details to 'sign-in' when the app first fires up.....having done which, you get 90 days of free use. At that point, the 'free' license expires.....but you simply sign-in again, and you're up-and-running once more; the cycle will repeat ad infinitum. No muss, no fuss.....no cost. 
I can only speak for myself here. Having an Nvidia card, two additional items will be required;
libCg.so
libCgGl.so
One's half a meg, the other's around 20! These are the Nvidia & OpenGL core runtime libraries; not included in the official driver packages, but easily installed from the PPM. (Search for "libcg"; "lib "cggl" should pop-up alongside it.....select and install the two together).
For KLV, I've 'borrowed' these two items from Fossapup64. It runs fine with these.
I cannot say what the procedure will be for Intel/AMD chips/GPUs. You won't know until you fire-it up; initially, I will advise launching via the terminal, since this will help to identify anything that may be needed.
Anyhoo; if anyone might be curious to take a look at this, you can find it here:-

As with all the portables, d/l; unzip; move the portable's directory anywhere you like outside the 'save'. Click to enter, click 'LAUNCH' to fire it up. Scripts permit adding/removing a Menu entry if required, from wherever the thing may be. It'll even run happily from a flash-drive...
Enjoy!
Mike.
