Kdenlive/Manual/Capturing
Capturing
Kdnelive provides functionality for capturing video from external devices - Firewire, FFmpeg, Screen Grab and Blackmagic.
You configure video capturing from Settings Menu > Configure Kdenlive> Capture.
You define the location your captures will end up using Settings Menu > Configure Kdenlive>Environment>Default Folders
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 using recordMyDesktop. There is an open defect with this functionality - See bug tracker ID 2643
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.
