Clip Properties

You can display and edit clip properties by selecting a clip in the Project Bin and using the Menu ‣ Project ‣ Clip Properties, or selecting Clip Properties from the right-click clip context menu.

Clip Properties are displayed in their own widget. You enable it from the Menu ‣ View ‣ Clip Properties. If it is not enabled when selecting Clip Properties as described above, Kdenlive will automatically enable it. By default, the widget is part of the same workspace dock as the project bin. As with any other widget, you can move it around within the same dock or put it to another or even into its own dock. See the chapter about Workspace Layout.

The Clip Properties widget has several tabs:

• File Info - displays general file info

• Properties - allows editing some properties

• Audio Properties - displays properties of the audio stream

File Info

The first tab is the File Info tab. It displays general information about the file, its streams, and other technical data.

The File Info tab

At the top, the filename with its full path is displayed as a link. Clicking it opens your OS file manager at that particular location.

Properties

The Properties tab displays those properties of the clip that Kdenlive allows you to change.

Editable properties of the selected file

Check the property you want to change, and then enter or select the new value.

Duration:

The duration of the original clip. Not really useful for video clips, but color clips, title clips, images, and image sequences. However, if set for a video clip the following rules apply: If the new duration is shorter than the clip duration, then the clip is trimmed. If the new duration is longer than the clip duration, then the last image is repeated (freeze frame) until the new duration is reached.

Aspect Ratio:

The current aspect ratio of the clip

Proxy clip:

If proxy clips are enabled for the project (see the chapter Project Settings), you create a proxy file for the selected clip. If a proxy file exists already, this is checked and the encoder format is displayed. Click on Delete proxy file to delete the proxy file. The icon opens a flyout with additional options:

Frame rate:

The current frame rate in fps

Scanning:

The current scan format (interlaced or progressive)

Field order:

The current field order (only applicable to interlaced scanning)

Disable auto-rotate:

If checked will prevent the image to be rotated according to its embedded rotation setting (not present in all images)

Color space:

The current color space of the clip

Color range:

The current color range of the clip. This is mostly relevant for videos intended for broadcasting.

There is a difference between audio streams and audio channels. Kdenlive does display the different audio streams with a list. Consumer video camera mostly have only 1 audio stream with i.e. 6 channels, like 5.1 audio. Kdenlive does not allow manipulation of the audio channels,
