I understand the concern and that it is indeed a complicated task to
find a sane and working set of video-apps for Linux.

Since the free video-apps are by far not that mature as the audio-stuff
I can only add some more points for the discussion.

Avidemux is some kind of a swiss-army-knife for working with
video-files. I did use it 2 or 3 times as a video-editor but I use it
frequently to extract audio and manipulate formats. There are great
commandline-apps for these tasks and these are easy to use. But it is
not at all easy to know all the options you have in the jungle of
formats for video so I consider Avidemux a very user-friendly app since
it allows to work with these options intuitive. (Somewhat like
PHPMyAdmin if you start working with MySQL...)

> OpenShot is arguably the easierst, most user friendly video editor.

OpenShot is nice and its design is very promising. But as I tested it in
May last year I had so many crashes in so many different normal
situations, that I must say: if it was not developped in a most
astounding speed in the last months, it cannot be considered a
application ready for end-users.

It has the best Jack-implementation I ever had the fun using with a
video-editor. It produces crashes also that can give you a situation, if
you are working in a studio with a customer but I made several
video-projects with it and the work went like a breeze - its
desaster-recovery system faild only once in 10-12 crashes I had with it
in several hundred houres of work. So I would say: even while 1 crash in
10 h is still much too much, it is recommendable.

For starters I think, OME should be enough (given, that all the
frei0r-plugins and of course ffmpeg are on board also).

But the users should be informed in a nice and understandable way, that
much more is possible, if they install a list of additional apps.

Unfortunately, OME is not actively developed these days. Since it is
still one great app, I still would recommend its inclusion - maybe this
could even lure Richard Spindler into further developing it ;-)

Absolutely no offence ment. :-)

But let me advocate LMMS some more:

Workflow: Creating electronic music for absolute beginners.

Requirements: LMMS

* open LMMS and choose alsa for audio-i/o
* drag some instruments, presets and/or samples from the browser at the
left to beatlines or tracks
* hit play and have fun
* invite you good friends rightklick, middleklick and the CTRL-key to
the party and have more fun
* connect any MIDI-Keyboard/Controller to tracks and parameters and have
serious fun.

Lmms is the most beginner-friendly sequencer I ever have seen under
Linux and it is at the same time capable enough to do complex advanced
stuff with it also. Qtractor is much more complicated. But while
Qtractor comes with Support for DSSI and LV2 and very capable
Audiotracks, LMMS has only crude sample-tracks and knows only LADSPA (it
comes whith great built-in synths/samplers though and can be compiled to
use VST).

So both have their audience and their unique powers. Users, that come
from Windows/Mac are used to have *all* these powers available and a
Linux-distro geared towards creative users should offer as much powers
as the free-software-devs are providing.So yes: both are sequencers but
if you want to make people happy, you should have both.

Beginners will be appalled by the learning curve Qtractor demands, some
more experienced users would be disappointed, if the flexibility and
audio-capabilities of Qtractor would not be available. So I think,
giving both a place in the standard-menu is absolutely worth the hassle.

See above - it is indeed that easy ;-)

To give beginners an easy, well documented and obvious method to install
more stuff ican be a reasonable alternative.
