[Sugar-devel] [SoaS] Record with camera and microphone input on VirtualBox / VMWare

Thanks to everyone for your help and suggestions, and to Christoph for
posting the initial request for help. The idea here is to establish two
levels /Protocols of screencast ability for the making of video tutorials:

1) A Mac/PC based system using SoaS that would allow us to produce
professional level videos with all the bells and whistles.
2) An XO based workflow using Sugar's own Screencast activity

The concept would be to produce a few, high quality exemplars that could be
easily reproduced by folks anywhere with a Mac/PC, and to inspire local
XO-based tutorials that can be produced by kids and for kids. There are
already some great exemplars of that at archive.org where elementary school
kids have made their own Scratch tutorials in ogg.

Like many of you, my test with VB got the green light on the cam, but a
black screen, but on VB the audio worked.
On Parallels, we got the still cam working, but no video and no audio.
I haven't tried VMware yet.

VB would be best cause it is free, and I think the various suggestions that
we try an external USB mic and cam, adding them as devices, might be the
answer. My one complicating factor might be...could the Rode Podcaster USB
mic we use to narrate the tutorials also be used simultaneously in Record
to bring in the audio. We are going to test the "USB devices with USB
passthrough" idea this weekend, and I will start testing Sugar's Screencast
more rigorously. I have had success on a 1.5 at low and medium quality, but
the high quality versions have been choking for me. I want to see what
quality I can get, and how long the screencast can be, optimally.

Thanks for all your help. We are just trying to pioneer a system that will
be duplicable and scaleable...and affordable. If we figure it out, that
will be the first screencast we make!
