Rendering

Rendering is the process where the edited clips are saved into a single complete video clip. During 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 Ctrl + Enter shortcut.

Rendering Profile Categories

Kdenlive offers many different preset rendering profiles to choose from. The rendering profiles are grouped into categories. See picture below.

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 merely 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

This will open the Save Profile dialog and the Parameter section will be filled in with the render parameters of the profile that you had selected when you clicked the 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.

Rendering Using the Guide Zone Option

This makes use of Guides to define a region of the project that is to be rendered. See Rendering Using Rendering Scripts.

Rendering Using the Selected Zone Option

If you select the Selected Zone radio button from the bottom of the render dialog then Kdenlive will only render that bit of the project that has a selected zone created for it. See Creating Zones in Project Monitor

Render Overlay

This option overlays a time code or frame count over the rendered video. This will put the overlay over the entire rendered project. Alternatively you can use the Dynamic Text effect to place overlay over selected regions of the video.

Export Metadata

Check this to have the metadata setup under project settings > Metadata be placed into the metadata of the rendered file.

and this is the metadata on the resulting clip (rendered with Export Metadata checked)

This appears to reveal a bug in ver 0.9.4 - the full title is not placed in the meta data - it is truncated at the first space.
