linuxserver/kdenlive
Kdenlive is a powerful free and open source cross-platform video editing program made by the KDE community. Feature rich and production ready.
Simply pulling
lscr.io/linuxserver/kdenlive:latest should retrieve the correct image for your arch, but you can also pull specific arch images via tags.The architectures supported by this image are:
Architecture | Available | Tag |
|---|---|---|
x86-64 | ✅ | amd64-<version tag> |
arm64 | ✅ | arm64v8-<version tag> |
armhf | ❌ | |
The application can be accessed at:
- http://yourhost:3000/
- https://yourhost:3001/
In order to perform hardware transcoding you will need to mount a video device into the container. Some of the default hardware rendering/transcode profiles will point to devices in /dev/dri for
vaapi_device. Make sure the profile you are using points to the correct device in the container. IE if you have intel integrated graphics along with an Nvdia or AMD video card you might have renderD128, renderD129, etc. To check which device is which use vainfo from inside the container: (right click the desktop and open xterm)vainfo --display drm --device /dev/dri/renderD128
Hardware acceleration users for Nvidia will need to install the container runtime provided by Nvidia on their host, instructions can be found here: https://github.com/NVIDIA/nvidia-docker
We automatically add the necessary environment variable that will utilise all the features available on a GPU on the host. Once nvidia-docker is installed on your host you will need to re/create the docker container with the nvidia container runtime
--runtime=nvidia and add an environment variable -e NVIDIA_VISIBLE_DEVICES=all (can also be set to a specific gpu's UUID, this can be discovered by running nvidia-smi --query-gpu=gpu_name,gpu_uuid --format=csv ). NVIDIA automatically mounts the GPU and drivers from your host into the container.This container is based on Docker Baseimage KasmVNC which means there are additional environment variables and run configurations to enable or disable specific functionality.
Variable | Description |
|---|---|
CUSTOM_PORT | Internal port the container listens on for http if it needs to be swapped from the default 3000. |
CUSTOM_HTTPS_PORT | Internal port the container listens on for https if it needs to be swapped from the default 3001. |
CUSTOM_USER | HTTP Basic auth username, abc is default. |
PASSWORD | HTTP Basic auth password, abc is default. If unset there will be no auth |
SUBFOLDER | Subfolder for the application if running a subfolder reverse proxy, need both slashes IE /subfolder/ |
TITLE | The page title displayed on the web browser, default "KasmVNC Client". |
FM_HOME | This is the home directory (landing) for the file manager, default "/config". |
START_DOCKER | If set to false a container with privilege will not automatically start the DinD Docker setup. |
DRINODE | If mounting in /dev/dri for DRI3 GPU Acceleration allows you to specify the device to use IE /dev/dri/renderD128 |
Variable | Description |
|---|---|
--privileged | Will start a Docker in Docker (DinD) setup inside the container to use docker in an isolated environment. For increased performance mount the Docker directory inside the container to the host IE -v /home/user/docker-data:/var/lib/docker. |
-v /var/run/docker.sock:/var/run/docker.sock | Mount in the host level Docker socket to either interact with it via CLI or use Docker enabled applications. |
--device /dev/dri:/dev/dri | Mount a GPU into the container, this can be used in conjunction with the DRINODE environment variable to leverage a host video card for GPU accelerated appplications. Only Open Source drivers are supported IE (Intel,AMDGPU,Radeon,ATI,Nouveau) |
This container is capable of delivering a true lossless image at a high framerate to your web browser by changing the Stream Quality preset to "Lossless", more information here. In order to use this mode from a non localhost endpoint the HTTPS port on 3001 needs to be used. If using a reverse proxy to port 3000 specific headers will need to be set as outlined here.
To help you get started creating a container from this image you can either use docker-compose or the docker cli.

Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate
<external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.Parameter | Function |
|---|---|
3000 | Kdenlive desktop gui |
3001 | Kdenlive desktop gui HTTPS |
Env | Function |
|---|---|
PUID=1000 | for UserID - see below for explanation |
PGID=1000 | for GroupID - see below for explanation |
TZ=Etc/UTC | |
SUBFOLDER=/ | Specify a subfolder to use with reverse proxies, IE /subfolder/ |
Volume | Function |
|---|---|
/config | Users home directory in the container, stores local files and settings |
Parameter | Function |
|---|---|
/dev/dri | Add this for hardware acceleration (Linux hosts only) |
Parameter | Function |
|---|---|
--shm-size= | This might be needed to prevent crashing |
--security-opt seccomp=unconfined | For Docker Engine only, this may be required depending on your Docker and storage configuration. |
You can set any environment variable from a file by using a special prepend
FILE__.As an example:
-e FILE__PASSWORD=/run/secrets/mysecretpassword
Will set the environment variable
PASSWORD based on the contents of the /run/secrets/mysecretpassword file.For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional
-e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.When using volumes (
-v flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.
In this instance
PUID=1000 and PGID=1000, to find yours use id user as below: $ id username
uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)
We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.
- Shell access whilst the container is running:
docker exec -it kdenlive /bin/bash
- To monitor the logs of the container in realtime:
docker logs -f kdenlive
- Container version number
docker inspect -f '{{ index .Config.Labels "build_version" }}' kdenlive
- Image version number
docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/kdenlive:latest
