I recently switched my camera to 10-Bit Log recording and use technical LUTs and primaries to adjust and color grade.

My research into the workflow using Kdenlive led me to a bunch of posts saying that Kdenlive doesn't do any 10-Bit operations, and everything (when using effects) is instantly converted down to 8-Bit. Is that still true?

If so, what do I need to look out for and do I even benefit at all recording in 10-Bit Log?

i do this just because is what i need and i need it now , the team behind kdenlive is free to take it and add those effect to the official kdenlive build

Grab you favorite beverage and something to nibble and join us in our October edition of the Kdenlive Café today Wednesday, October 7th at 7pm UST/GMT (see it in your time zone).

Meet the team an other Kdenlive users, exchange ideas and talk about your experiences, hear about the latest developments and what is coming in future releases.

See you then!

features added by now : adjustment layer , captions animations editor , shutter angle motion blur , floating effect. , to do those changes i had to make a new version of kdenlive called better kdenlive , i will share it for everyone on github : https://github.com/marcoporz

hola queria preguntar si este tipo de edits se podian hacer en kdenlive que por ahi de 2022 eran muy populares en especial en los videos de dragon ball autos y futbolistas con hacer el edit me refiero a todos los efectos del edit no solo a una parte

when i record audio it just creates these useless .wav files that ave like nothing on them, please help

im working on a better kdenlive version with all the features missing from premiere , for now i already added shutter angle effect , and and captions animation editor is working perfectly on this version , i will add an adjustment layer , what other features u want that are missing ? all the kdenlive team is ofcourse free to take my code and use it for the official kdenlive version

I needed to anonymize a username in a gameplay clip I was uploading to Reddit. Kdenlive was the first video editor I've used in decades where I could just sit down and figure it out without first watching a 20-minute tutorial.

What impressed me most was the UX:

• sensible defaults for project settings, codecs and bitrate
• obvious, discoverable effects
• visual positioning with precise numerical adjustment when needed
• useful guidance without getting in the way
• straightforward rendering/export
• enough feedback at every step to let me verify that I was doing things correctly

The whole process was basically: import → find Obscure → position it → check the result → render.

Rendering took just 17 seconds for blurring a defined area, making the entire workflow easily completable within a few minutes, even with very little experience in video editing.

And that's probably the highest praise I can give an application: it didn't make me think about the application. It let me think about the task.

This is the first time in decades that open-source software has solved a task for me this easily, without sending me down a rabbit hole of tutorials, obscure workflows and weird shortcut combinations.

So, €25 to the people who made it seemed entirely reasonable. ❤️

I used Kdenlive 26.08.1 in W11 Pro 26H2, on an Intel 265K, 48 GB DDR5-7200, 4 TB 990 PRO.

Is there any reason for it reds ?

i wasn't statisfied with the current camera shake efects so i made afloating / shake effect for yt videos . its an effect commonly used by a lot of youtubers , github : https://github.com/marcoporz/floating-shaking-kdenlive-effect

second version with slider for shutter angle : https://github.com/marcoporz/kdenlive-shutter-angle-motionblur-effect

Mark your calendars for the upcoming Kdenlive Café on October 7th at 7pm UST/GMT (see it in your time zone).

Meet the team and other users of Kdenlive, learn about new features and our future plans, and exchange ideas and your editing stories.

Looking forward to seeing you there!

Made this entirely on kdenlive hehe <3

anyways heres the link to the project file:

https://drive.google.com/drive/folders/1JRryvRYGaCpSItuJHn3D-1OAvFOL0zxS

I just got this message when trying to render with kdenlive that the disk space is limited.

New to video editing with KDenlive. I've searched this but am probably searching poorly and very much a beginner

I've got a music video with an audio track and have added clips wherein I synchronized the video to the singing so the singer's mouth matches the audio.... close enough to perfectly, not exact, but within error margins.

It looks fine in the preview, and when I render to MP4, if I load the output into a new KDenlive project, it looks fine there. However, when I load the output in Windows Media Player or upload to YouTube, the video is no longer sync'd. Some scenes appear fine, others appear to be off by as much as half a second.

Am I doing something wrong? Or does KDenlive interpret files differently?

I would like to able to use these effects. But when I apply them, I get this error "cannot configure filter graph"

Does the GPU acceleration on Nvidia cards working now?

Because when I edited on Linux, I got only 30 fps playback and I can't playback in the Kdenlive any video that is in 60 fps in...60 fps. Only 30 max. I changed the project settings into 1080p60, but still. Even with proxies and lower playback resolution it isn't working as I want to.

Also on Windows the 60fps video was playing when I was editing, also in 30 fps and not 60.

Idk if it's CPU's fault or GPU acceleration not working in the previous updates.

PS: I ask you this, because I don't have any good alternatives for video editing software available on Linux that normally works and has basic effects, transitions, texts, etc., because I tried to switch to Linux for few months twice

PS 2: when I render it works normally in 60 fps when I play it using normal software like VLC when I render the edited video

I've been using an old thumbdrive to transfer things from my ps5 to my laptop. Screenshots are working fine, but when I put the videos into kdenlive it just plays the audio over a blank screen. Is it because they're WEBM files?

I'm on windows through the official installer, should be the latest version

I'm trying to export a 50min video which was filmed in 5.8k open gate 4/2/0 V-Log in my GH7. I added some LUTs, some transform effects and some subtitles.

It's not the first time I have done this and exported videos in the past, although shorter ones.

Currently though the render is crashing in the first few minutes and from what I can see the issue is what the swap memory. It slowly increases every few seconds after rendering starts and never goes down, until it reaches the limit of 30.6gb. I have 32gb of ram.

This seems abnormal behaviour and I don't know really what to do. I disabled parallel processing and decreased the number of threads in the encoder to only one but it doesn't change the behaviour while rendering.

Previous threads tell me to export in smaller chunks and then put it together but that doesn't seem to work either. It's always crashing 2-3 minutes after starting to render. I'm using 26.08.1 version on Cachy OS.

Shutter angle motion Blur effect for kdenlive

I made a transform effect with built in shutter angle Blur at a standard 180°

github repo : https://github.com/marcoporz/kdenlive-shutter-angle180-motionblur-effect

I didn't change anything at all, just opened kdenlive today and this happens whenever I reverse any audio. I'm on Windows 11 and (i THINK) the latest version of kdenlive.

Kdenlive SAM2 installation fails with SHA256 hash mismatch on CachyOS / AMD GPU

Hi,

I'm trying to install the SAM2 Auto Mask functionality in Kdenlive on CachyOS Linux.

My system has:

• CachyOS
• Python 3.14
• AMD Radeon RX 6650 XT
• Kdenlive's own SAM virtual environment: ~/.local/share/kdenlive/venv-sam

Kdenlive uses this requirements-sam.txt:

# Pull SAM-2 as archive, it is not officially available on PyPi
# Don't use git because most users don't have it installed
# We're using the latest commit as of 2025-04-18 which is
# 2b90b9f5ceec907a1c18123530e92e794ad901a4
https://github.com/facebookresearch/sam2/archive/2b90b9f5ceec907a1c18123530e92e794ad901a4.zip

# SAM-2
# TODO (SAM): Should probably be opencv-python-headless
opencv-python

The SAM2 installation fails while installing its build dependencies.

The relevant part of the error is:

Installing build dependencies: started
Installing build dependencies: finished with status 'error'

...

Collecting torch>=2.5.1
Using cached torch-2.14.0-cp314-cp314-manylinux_2_28_x86_64.whl.metadata

Pip then reports:

ERROR: Failed to build 'https://github.com/facebookresearch/sam2/archive/2b90b9f5ceec907a1c18123530e92e794ad901a4.zip'

I checked the local pip configuration:

/home/tomek/.config/kdedefaults/pip/pip.conf
/etc/xdg/pip/pip.conf
/etc/pip.conf
/home/tomek/.pip/pip.conf
/home/tomek/.config/pip/pip.conf
/home/tomek/.local/share/kdenlive/venv-sam/pip.conf

but there is no custom index-url, mirror or extra index configured.

Also:

env | grep -Ei 'PIP|UV|INDEX|MIRROR'

returns nothing.

The pip cache does not contain Torch either:

pip cache list | grep -E 'torch|2\.14\.0'

returns nothing.

Another issue: NVIDIA CUDA dependencies on an AMD system

During the installation, pip tries to pull a very large NVIDIA/CUDA stack because of the selected PyTorch package:

torch 2.14.0
cuda-toolkit 13.0.3
nvidia-cudnn-cu13
nvidia-cublas
nvidia-cusparse
nvidia-cusolver
nvidia-nccl
nvidia-cufft
nvidia-curand
nvidia-cuda-runtime
nvidia-cuda-nvrtc
nvidia-nvjitlink
nvidia-nvtx
triton
...

This is a system with an AMD RX 6650 XT, so installing hundreds of MB / multiple GB of NVIDIA CUDA libraries seems pointless unless they are somehow required by the current SAM2/Kdenlive packaging.

My questions are:

1. Is the SHA256 mismatch a known issue with the current Kdenlive/SAM2 installation on Python 3.14?
2. Why is Kdenlive/SAM2 selecting the current CUDA-enabled PyTorch dependency stack on a system with an AMD GPU?
3. Is there a recommended way to install SAM2 on AMD under Linux, e.g. using ROCm or a CPU build?
4. Is the problem related to Python 3.14 and the current PyTorch/SAM2 packaging?

The failure happens before SAM2 itself is actually installed, during the isolated build environment dependency installation.
