Rendering
Rendering is the process where the edited clips are saved into a single complete video clip. Durring the rendering process the video can be compressed and converted to a number of different video formats (AKA codecs).
The rendering dialog is brought up from the render button 
, from selecting render in the Project Menu or by the <ctl><enter> shortcut.
Rendering Profile Categories
Kdenlive offers many different pre-set rendering profiles to choose from. The rendering profiles are grouped into categories. See pic.
File Rendering
DVD Rendering
DVD Rendering produces files that are compatible with DVD authoring software. MPEG2 files created from file rendering profiles are less likely to be compatible with DVD software.
Note that this option does not create a DVD file system. It mearly creates DVD compatible MPEG2 files that can be used by DVD authoring software. If you check the Open DVD Wizard after Rendering check box then the DVD Wizard will open and you can use this to create a DVD file system (in .ISO format). The DVD Wizard is also available from the File Menu.

Create Custom Render Profiles
You can create your own custom render profiles by clicking the button highlighted in the screen shot below
Ths will open the Save Proile dialog shown above and the Parameter section will be filled in with the render parameters of the profile that you had selected when you clicked the add new profile button. You can edit values in the parameters and save your own custom render profile.
The parameters in the rendering profile are ffmpeg parameters. For an explanation of there meaning check the ffmpeg man(ual) page or type ffmpeg -h in a command prompt.
Rendering In Batch mode
If you have a lot of rendering jobs to do you can use kdenlive to create rendering scripts which you can accumulate and then execute in a batch mode overnight. See Rendering Using Rendering Scripts.
Alternatively, once you have submitted a rendering job on a project and it is up and running in the Job Queue you can drag the render window out of the way and edit the project some more or load a new project and render that one too. The second submitted render job will go into the Job Queue. Editing the project after a render job is submitted will not change the settings on that job.
