Working with KDENLIVE
I have to say upfront that KDENLIVE shares the interface and usage model that many of the video editing programs have. In other words, the basic structure of video editing programs is present in KDENLIVE.
When you open KDENLIVE, you see the window split into four parts. The top part is the menu and icon bar as is almost always the case. The middle part is split into two, the left part is the project tree, the right side is previewer/timeline editor, and the bottom part is the timeline and keyframes.
I would like to make a note about importing movie clips before we get going. You can download the files to your computer by using a file manager (putting your camera in USB Mass Storage Mode), by using specialized software if your camera has one for Linux, or by importing directly from KDENLIVE’s interface. In the right pane, clicking on the “Capture Monitor" you can access the features for importing clips directly to your computer. I suggest you to check the compatible cameras before you go with this option. Personally I would go with the USB Mass Storage Mode, where, after plugging your camera into a USB port, your computer will recognize the camera as an external disk and you will be able to cut/copy the contents to your hard disk. This mode will be easier and will use up fewer resources of your computer (sometimes the programs crash when importing from cameras). If USB mode is not available, then your only option will be to use the other connection methods.
Let's get started. You have to import all of your movie clips that you will use in the project to KDENLIVE. You can go through this importing process from the menus. When all your clips are imported, let your imagination and creativity go wild. Drop your clips to the timeline at the below pane, where KDENLIVE will automatically arrange the timings depending on the clip length. No need to say, you can cut/copy/paste in your clips. If the part between 05:13 and 08:42 is important to you, go ahead and cut it, paste it, and discard the changes. KDENLIVE lets you use your clips like a word processor.
