I'm also a volunteer working on this stuff in my spare time here in Sydney
(with groups like SLUG and SyPy). I care about this problem enough that I'm
also donating my own money and other resources to the problem.
Firstly, I want to say that it is great that your user group is thriving
and that you are thinking about how to do better recording. At the moment I
don't think your proposal is a good allocation of Linux Australia's
resources. For a similar amount of money and different approach we can help
improve the recordings substantially better than getting you a new camera
On a semi-related note, I'd also like to mention the normal life cycle of
recording FOSS user groups (having been through this myself and with a
number of other people).
1. You gets excited about user group.
2. You figure out way to record user group, produces a bunch of
3. Then one of three things happen;
1. You get busy with other things or for other reasons can not attend
the event. Nobody else is able to get your system working.
2. You gets behind in publishing videos, the videos pile up into an
insurmountable amount of work, you give up.
3. People get sick of the recording holding up the user group
proceedings and stops making the effort to make it possible.
4. Videos are no longer made.
5. Repeat from step 1 with a different person.
Breaking this cycle is a hard thing to do and I've yet to come up with a
foolproof solution. I've made a number of attempts to help solve all the
three problems with various results.
