Kdenlive 16.12.0 will see further improvements to its library clip expansion (and, in consequence, to MLT playlist import). Not every Kdenlive user will notice the improved functionality, as it affects only library clips where the same image sequence or title is used multiple times.

In particular, if you (re) use the same image sequence clip, title clip, or even color clip multiple times in the same libary clip, such image sequences and titles  will only be added once to your project bin. Before Kenlive 16.12.0, multiple instances of the same clip in the timeline unfortunately resulted in these clips getting added multiple times to the project bin. To emphasize, this undesired behavior only affected image sequences, titles, and color clips.

When expanding a library Kdenlive 16.12.0 will now check image sequences, titles, and color clips in the timeline for their content, clip name, and original bin folder location. If there is a match, then such a timeline clip will be added only once to your project bin.

    What is a “library clip”?

    • The DiveO

      A “library clip” is a clip with the “.mlt” suffix, and in particular, a clip that has been added to your personal Kdenlive library. They show up in Kdenlive’s library pane.

      Internally, when you select some clips & transitions from the timeline and add them to Kdenlive’s library, these clips and transitions are stored in the file system in a “.mlt” file (which is an MLT playlist to be precise), and shown in the library widget as a new library clip.

      Technically, Kdenlive projects are also MLT playlist files. When you add a clip from the library pane to your project this simply adds the underlying MLT playlist file to your project. But in contrast to other clips, such as an MP4 video, you can “expand” library (that is, MLT playlist) clips to get back the individual clips and transitions inside it.

    Hi. I’m trying to archive my kdenlive projet (Project => archive project).
    However, I receive an error message for missing clip (C:\Program Files\kdenlive/).
    It is for the the third time, for 3 different projects. I tried to reinstall kdenlive, but the problem persists.
    Is there a way to fix this issue?

    Hola, instale la ultima version de Kdenlive pero no tengo todos los efectos disponibles en la versión para el sistema operativo window y tampoco tengo la opción en el menú para descargar librerías.
    Donde puede obtener los pluging de efectos? en particular me interesa el de “desenfocar y ocultar”

    Hola, cuando copio una imagen en kdenlive me aparece un diálogo como este : “no profile found for your clip. create and switch to new profile. profile fps ajusted from original” y al poner la imagen en una de las pistas me dice que dura 10 minutos y se pone toda ella de color marrón anaranjado. Cual es la solución, cambiar el tamaño de la imagen, menos de 1000 píxeles, o el formato jpg?

    Is it possible to change the duration of all selected clips e.g. have inserted a bunch of still images and want them all to have a 2 second duration. though after selecting all of these (and only these images) and then using the context right click menu option of edit duration only the clip directly under the cursor is changed and not the selection.

    Is this ‘do-able’ in another way besides one a time?


    • Julius Künzel

      At the moment it is not possible to change the duration of multiple selected items at once, but there are two other possibility: Either you can use a slideshow clip or you can adjust the default duration of a image in the settings (note this duration is applied when importing the images so you have to import them again after you changed the default duration to make it work)
