I just got kdenlive and I'm trying to figure out how to use it. :)
I got it as an .rpm through OpenSuSE's repos and this is the version:Version 0.8.2.1 and I'm running OpenSuSE 11.4 64 bit.

When I try to capture video from my Namtai eyetoy webcam, I got this message when I started it in a terminal:

When I start the capture, I use Video4Linux, and kdenlive tells me that my video will be saved in /home/myusername/kdenlive/ but after stopping the capture, there is no video file.
The eyeToy seems to work fine, I can see my image in the preview window.

Other times, I might get:

And after another try, I'll get:

My recording devices are as follows:

arecord -l

If I do this in a terminal:
ffmpeg -f alsa -ac 1 -ar 48000 -i hw:0,0 -acodec mp2 -f video4linux2 -s 640x480 -r 30 -i /dev/video0 -vcodec mjpeg -sameq test.avi

It works nicely.

Is there a tutorial around somewhere that I can follow? Can I edit an .avi file in kdenlive that I already recorded?
