Sure thing.  The bulk of the stuff I do is in the under 10-minute
range; demo reels, montages, animations, and television commercials.
While these projects are certainly not long-format, they can end up
with some pretty complex track structure (classic television commercial
problem: cram 10 minutes of information into 30-60 seconds ;).

I regularly use Cinelerra on one of three machines: an eight-year-old
box with an Athlon XP 2500+, a laptop with a hyperthreaded 3GHz P4, and
another laptop with a dual core Turion64.  All of these machines have
about a Gig of RAM and I often edit to an external firewire hard
drive.  Two run Gentoo and one runs Ubuntu.  So I don't exactly work on
machines that are computational powerhouses.

I edit png sequences (from Blender), DV (usually wrapped in Quicktime
or avi), and uncompressed (again, usually wrapped).  I recently edited
the SIGGRAPH Demo Reel for Blender using Cinelerra (though I did use
ffmpeg and Blender for some file conversion for a few formats that
Cinelerra didn't play nice with... a step I would rather have skipped).
The demo reel posed some interesting challenges because, not only did I
get some pretty esoteric codecs as submissions, not everyone submitted
their work in the same resolution and framerate.  Once I had the video
files in "nice" codecs, Cinelerra actually handled the resolutions and
framerates fairly well.  It even did well with a different project that
I rendered from Blender to be in NTSC anamorphic widescreen.

Graham's post is right on target.  I like to think of Cinelerra as more
idiosyncratic than outright buggy.  There are a number of things that
it does very well... and there are some things that require you to do a
bit of dancing to get it to work right.  But once you muscle your way
through that, there are quite a few possibilities open to you.
