Capturing
Kdenlive provides functionality for capturing video from external devices - Firewire, FFmpeg, Screen Grab and Blackmagic.
You configure video capturing from (more on this here).
You define the location your captures will end up using (more on this here).
To execute a video capture select the Record Monitor and choose the capture device from the drop down in the bottom right.
Firewire
This captures video from sources connected via a firewire (also known as - IEEE 1394 High Speed Serial Bus) card and cable.
FFmpeg
I believe this captures video from an installed Web Cam using Video4Linux2.
Screen Grab
This captures video of the PC screen. In version 0.9.2 it uses recordMyDesktop to do the capture. There is an open defect with this functionality in ver 0.9.2 - See bug tracker ID 2643.
In version 0.9.3 the Screen grab is done by the ffmpeg functionality instead. For screen capture to work in ver 0.9.3 the version of ffmpeg installed needs to have been compiled with the --enable-x11grab option. Ubuntu comes with an ffmpeg compiled with this option.
To check on your linux distro type "ffmpeg -version" in a terminal and look for --enable-x11grab in the reported configuration info.
Blackmagic
This is for capturing from Blackmagics decklink video capture cards (AFAIK). Not sure how stable this code is at the moment. See defect 2130.
