Omgeving¶

This section defines some of the most important settings for Kdenlive.

configure_environment_2412 — The Environment section¶

1:: Concurrent threads. Defines the number of threads to use for proxy clip generation and transcode jobs. Those jobs will run in the background. The value entered is passed to ffmpeg as the -threads parameter. Increasing this parameter may not have an effect if you have changed the proxy encoding settings using project settings to a codec that ffmpeg does not do multi-threading on. Multi-threading is supported for MPEG-2, MPEG-4, H.264, and VP8.
2:: Use lower CPU priority. This instructs Kdenlive to lower the priority of the proxy clip generation and transcode jobs. It helps keeping the main UI responsive when proxies are created or clips are being transcoded.
3:: Warn if cached data exceeds. Add a maximal cache size that Kdenlive checks every two weeks. Kdenlive issues a warning message if the total cached data size exceeds this limit. If you need to purge the cache, use the Gegevens in de cache beheren feature.
4:: Check for updates. If checked, Kdenlive will show a pop-up window with a reminder if your version is older than six (6) months.
5:: Tabs for the different environment settings.

MLT-omgeving¶

These settings tell Kdenlive where to find the MLT executables and profile files. Only advanced users would really need to change these settings. Kdenlive is basically a frontend to the MLT program. If you have MediaInfo installed and provide the path here, Kdenlive shows more details in the clip properties. The values differ depending on your OS.

Kdenlive_Configure_environment_MLT_Windows — Environment variables in Kdenlive installed on Windows¶

Kdenlive_Configure_environment_MLT_Linux — Environment variables in Kdenlive installed on Linux¶

configure_environment_mlt_appimage_2412 — Environment variables in Kdenlive appimage on Linux¶

Standaard mappen¶

These settings tell Kdenlive where project files are to be stored. It also controls what folder Kdenlive will use as a temporary file storage location and where files captured from an external source will be saved.

Kdenlive_Configure_environment_default_folders — Standaard mappen onder Windows¶

configure_environment_default_folders_appimage_2412.webp — Default folders on Linux (appimage).¶

configure_environment_default_folders_linux_2412 — Default folders on Linux (flatpak).¶

Kdenlive_Configure_environment_default_folders_MacOS — Standaard mappen onder MacOS¶

Python¶

Python is used for the speech-to-text feature. These settings tell Kdenlive where Python can be found on your system or whether a virtual environemnt (venv) should be set up and used.

Python virtuele omgeving gebruiken (aanbevolen) Indien ingeschakeld maakt Kdenlive een map venv en kopieert/maakt symbolische koppelingen naar Python in deze map.

Door de virtuele omgeving (venv) te gebruiken slaat Python, als u het hebt geïnstalleerd op uw systeem, op in de map venv. Als u spraak-naar-tekst installeert zullen de VOSK en Whisper bibliotheken ook geïnstalleerd worden in de map venv.

Dit heeft vele voordelen inclusief gemakkelijker beheer van afhankelijkheden en verminderd risico van conflicten tussen pakketten en fouten veroorzaakt door afgekeurde software.

Path for venv:

Linux: ~/.local/share/kdenlive/venv
Windows: %LocalAppData%\kdenlive\venv

To remove the installed venv packages click on Delete. This will completely remove the venv folder with all installed packages. Note that this does not remove the downloaded models (VOSK/Whisper) that can still occupy significant disk space.

Kdenlive_Configure_environment_python — Tabblad Python onder Windows¶

configure_environment_python_appimage_1_2412 — Python tab on Linux (appimage) not using venv¶

configure_environment_python_flatpak_1_2412 — Python tab on Linux (flatpak) not using venv¶

configure_environment_python_flatpak_2_2412 — Python tab on Linux (flatpak) using venv¶

Standaard toepassingen¶

These settings control which external application opens when you choose Clip bewerken for a clip in the Project Bin.

configure_environment_default_apps_1_2412 — Settings for default apps¶

Image editing: A free software would be Krita.

Audio editing: A free software would be Audacity.

Animation editing: Kdenlive integrates nicely with and updates files automatically which are saved in Glaxnimate which is available from its homepage for Linux, Windows, and MacOS.

Notitie

Mac user: See these instructions how to install and run dmg files.

Notitie

Windows user: Make sure all the paths point to an .exe file. glaxnimate.exe is in folder %PROGRAMFILES%\glaxnimate\bin\.
