Hi! First of all, I'm grateful that you phrase this as “exciting stuff”,
because I'm excited, too. :-)

There's no such thing as OpenGL 2.2; there's 2.1 and there's 3.0. Movit's
OpenGL requirements are phrased in terms of extension support; OpenGL 3.0
contains all the features that are needed, but in almost any OpenGL 2.1
implementation will do (the extra extensions required over 2.1 are very

What kind of chipset is this? As far as I can see, every Intel chipset since
4th generation should have the required extensions. That's 2006, so you're
talking eight years ago. My main Movit developer laptop has 5th generation,
and it's starting to get so old that it's hard to find spare parts if
anything should break down.

I think this is an interesting question; when would be late enough? Should
really the needs of ten year old hardware dictate what feature the rest of
the world can do? As much as people in the FOSS world seems to love the
checkbox approach, unfortunately Kdenlive is not in a situation where there's
manpower to do both, as far as I can see (and if so, maybe that manpower is
better spent elsewhere?).

There are two different questions in play here, by the way; requiring support
for the OpenGL monitor (requires only OpenGL 1.1, I think?), and requiring
Movit support. Maybe one could get to the point where one would go for #1 but
not #2, but the answer to “is it worth it” is currently a resounding “maybe”
as far as I can see. :-)
