Greetings:

OS: Fedora 14 x64 with current CCRMA realtime kernel
Kdenlive 0.8.1 Rev 5815 (July 31 2011 cut)
MLT: 0.7.5
Toshiba Satellite Dual-core Turion 4GB

I just purchased the above webcam and it does an excellent job when using the quvcview program to capture video and audio, and I can load those clips into Kdenlive, but if I use the capture feature a 30 second clip is reported as being 8 seconds and both audio and video are output at this fast pace.

It behaves the same with either MJPEG or YUYV output from the camera. I'm using the video4linux capture driver. The results are the same with 640x480 or 800x600. The videos behave the same way when played in melt or in mplayer so it is recorded thus. If I just hit the "play" button in capture, a wonderful clear full-motion picture is displayed by Kdenlive. "melt video4linux2:/dev/video0" produces an excellent picture with a second delay or more, but smooth.

I noted that for 0.8.2 version of Kdenlive the capture system software back-end is changing (reflected in the cut I'm using).

So I have a few questions:

* This is not a camcorder, and I see nothing about registering webcams ... should we attempt to register webcams in the camcorder database, with sample footage, etc, or is this irrelevant due to the nature of the drivers/software that interface to them? This camera of course uses the uvcvideo driver.

* Since the capture system has just changed, is a bug report for this issue premature, or perhaps not related to kdenlive at all, or do you wish me to report it? (I have a bug reporting account).

Thank you! I love Kdenlive and would like to assist in some small way to make it better.
