Morning, n01ze.
Sadly, I have to concur with Mike about Python - yet again! - unfortunately it, along with mlt, seem to be requirements for almost all video-editors. Mlt by itself isn't a problem; the problem usually lies with the Python components that call it...
Anyway; I have some good news for you. Personally, I've never been able to use FlowBlade; I can install it, no problem, but because my monitor is an elderly 1024x768, FlowBlade complains that the screen size is too small (apparently, it's coded to expect a minimum 1280px width....)
------------------------------------------------------------
I use OpenShot throughout a 'kennels' of around a dozen Pups. I'm in Bionicpup32 right now. The package in use here is the Openshot 1.4.2 put together by
battleshooter, who, as with any project he put his mind to, went out of his way to construct it as thoroughly as possible, with absolutely
everything required to make it just 'work'.
You can find either .pet or SFS packages of 1.4.2 here, at my Google Drive a/c:-

Personally, I use the .pet package; I run with very large 'save-files', and size isn't an issue for me. A .pet package will overwrite components permanently; an SFS, on the other hand, temporarily 'overwrites' them while loaded, but upon unloading, the old components will still be there. I'd recommend the SFS package, since they're easier to dispose of if they don't work.
Help yourself to whichever one you want. Before using either one, I'd recommend that you un-install any Openshot stuff you may have installed from the PPM. The one in the PPM is the Qt5-based 2-series, and these are problematic because they've been written to expect the use of a dedicated graphics card. I don't use one, and TBH, unless you have a pressing need for the additional 'bling' of the 2-series Openshot builds, the final 1-series packages will do all you could want them to.
You
may find you still need to install 'frei0r-plugins' from the PPM. Although it's an integral part of battleshooter's build, Puppy doesn't always seem to recognise that it's there with an SFS package.
********************
When you get it installed, you may find that it'll open, but appear to be unresponsive. If you minimize the main window, you'll find a small window open underneath it, requesting installation of 'fre0r-plugins' for special effects. These are not essential - Openshot will still work without them! - but if not installed, this window needs to be 'OK-ed' before everything'll work.
If they are installed prior to firing-up for the first time, this window won't appear.
If you can't start it from the Menu entry, try starting openshot from the terminal, and let us have the readout, please?
----------------------
There's a couple of other 'goodies' that you may be interested in. Two video 'trimmers', as opposed to full editors.
The first is Avidemux - Mike knows all about this one. The package I'm going to link you to is an 'all-in-one' build by Patriot. This is in the form of an AppImage, which I turned the original into by the use of Fredx181's build-scripts. Download it; it's a single 'binary'. You can put this absolutely anywhere; just click on it, and it'll fire up, because AppImages unpack themselves into, and run from /tmp for the duration.
You can find it here:-

------------------------
The other one is a much fuller-featured video trimmer, known as 'Lossless Cut'. This particular one is the newest version that works with 32-bit Pups; there
are a couple of newer releases, but they're 64-bit only.
I described some of its functionality in this thread, here:-
http://www.murga-linux.com/puppy/viewto ... 15#1032815
(For some reason the images aren't showing at the moment; my guess is that PostImage may be down for maintenance, or summat....)
v2.1.0 is the version you want. You can find it here:-
https://github.com/mifi/lossless-cut/re ... x-ia32.zip
That's a direct link, BTW.
A word of caution; if you have reservations about space, this may not be for you. It's an Electron-based app, which means it essentially runs on top of a stripped-down Chromium browser, and it's pretty big.....around 270 MB when unpacked. The early versions were extremely basic, and I never felt the size was justified.....the later versions, however, are much more worth it, since they have far more extensive functionality.
You can get a feel for the way it works here:-

Hope that little lot may be of some use to you.
Mike.
