Hey All,
Thanks for the help with recording, they are on youtube!
http://www.youtube.com/user/MrLokiMissSeraphim
I've finally got VLC to work recording the videos, audio with straight
alsa, then mencoder to convert. I need to start recording them in the
correct aspect ratio for youtube though!
Next challenge, multi-track audio with ardour synced to multitrack
video and mix between the different videos of each instrument. Any
hints on an NLE?

Hi Loki,
I got a Logitech HD webcam (c905, they say it's one of the best
webcams together with the 9000 pro) but I still wasn't happy with the
frame rate and picture quality :(
At the end I settled with one of those little flip-cams:
http://camcorder.jvc.com/product.jsp?pathId=58
I got for one for 99€ discounted.
Example of the video quality (never mind my performance):
http://camcorder.jvc.com/product.jsp?pathId=58
Audio quality is abysmal but I can record with jack and multiplex over
its original audio.
I loose the ability to encode raw frames to the format I wish but the
USB bus can't sustain 30 fps HD frames anyway, so I think it's a good
trade off.
Cheers,
-Giuseppe

sorry wrong link:

Forgot to mention it encodes videos with h264/aac codecs into a mov container.
I would have preferred vp8/vorbis into a webm/matroska whatever container...

Blender for multi track video and if you want audio too but I would
suggest using blender only for the video and one of the many audio daws
ardour, qtractor, muse, rosegarden, audacity for the multi track audio
part. With blender 2.49 you can sync with a jack script but latest
blender svn has native jack support.
There is also lumiera, cinelerra, avidemux, and several other multitrack
video editors.
Also Robin Gareus has just released a patch for ardour3 that provides a
native video timeline using xjadeo which needs testing if you are keen.
Cheers.

If you don't need fancy video editing (zoom automation or sth.):
openmovieeditor.org - it's fairly easy to get started with and it can be
synced to JACK transport.
The alternatives are Blender (syncs with JACK) and Cinelerra or PiTiVi
or.. (kino, avidemux, lives..)
For the final mastering step (mux Audio/Video and export different
formats) use ffmpeg or mencoder.
ffmpeg -i input-video.avi \
-i input-audio.wav \
-vcodec libx264 -vpre hq -acodec aac -ab 192k -b 800k output.mp4
or
... -vcodec mpeg4 -acodec mp2 -ab 128k -b1000k output.avi
if your input-video.avi already has an audio-track that you want to
replace use '-map 0:0 -map 1:0'. Of course there are much more options.
man ffmpeg is your friend.

lumiera is still in the early stages of development not yet usable.

ardour3 that provides a

It's been announced on the ardour-dev list. It'd be great to get some
feedback; but note that ardour3 is still under heavy development.
svn co http://subversion.ardour.org/svn/ardour2/branches/3.0 ardour3
cd ardour3

I don't think I need it. :) Syncing with ardour would be great.
Hopefully I can make it all quick and easy, otherwise the singer
freaks out a bit.
All the current videos are done with 2 behringer omni mics and no post
processing. It would be nice if we could have more mics for when
tracks with a drummer, and electric tracks where I drown the singer
out a bit. Ardour3 or openmovieeditor look like the plan.
Thanks tons!

Ahh, open movie editor segfaults when i attempt to start it. I had to
add quite a few header files to get it to compile with gcc 4.4. I
think your ardour stuff might be more stable! I'm downloading blender
now though. Seems to be the extent of the jack transport aware
options.

Really fine work, Loki, my compliments to you and Miss Seraphim. :)

I use Kdenlive. Blender and LiVES have integrated JACK support, so you
might prefer either of those apps. But I like Kdenlive's UI best. Btw, I
wrote a series of Linux NLE reviews you might find informative:

I apologize for the omission of PiTiVi, I did profile it for Linux User,
IIRC, and noted that it was in its early stages of public release.
