A lot happened recently regarding Kdenlive. Let’s start with a some news from the swiss mountains:
Randa!
Last week, from wednesday to saturday I attended KDE’s annual Randa sprint organized by wonderful people. This was an occasion to work fulltime on Kdenlive. Here is a resume of what happened during these days:
- I submitted Dušan Hanuš’s color correction improvements (allow negative lift values in Lift/Gamm/Gain effect) in Movit and MLT. They have now been merged so we should soon have better color wheel correction.
- I made the first tests with Rafal Lalik’s TypeWriter effect, that would bring back this much requested feature for our users.
- I merged my code for speed effect and committed a very preliminary qml builtin effect stack (that should in the future allow easy adjustment of basic video properties like contrast, color balance, etc).
- I fixed a problem preventing multithreaded rendering that we discovered with Manuel when comparing Shotcut and Kdenlive.
- I spend several hours trying to debug a performance issue and finally discovered that it was caused by a small qml animation (blinking rectangle) – a reminder that fancy effects can sometimes really get in the way of productivity!
- I briefly exchanged with Scarlett regarding AppImage and Snap packages
- And several small other fixes: display warning when adding images smaller than 8pixels (not fully supported by MLT), fixed import of image sequences, removed unnecessary warning on first start about missing DVD tools (stuff from another century as I was told :).
You can still donate to KDE’s Randa fundraising to help. Kdenlive was also recently mentioned as the preferred video editor in a large survey of Ubuntu Desktop users, which makes us very proud!
First alpha testing version available
To share the result of these last months of work, I am happy to announce the first alpha version for Kdenlive 17.12, that contains the major code refactoring as well as the transition to Qml for the timeline display. This is an AppImage testing release. Just download the file, make it executable and run it. The x86_64 linux AppImage is available from the KDE servers: https://files.kde.org/kdenlive/unstable/kdenlive-alpha1-17.12.AppImage.mirrorlist
Beware: this is an experimental alpha version, allowing you to have a look at Kdenlive’s future and should not be used for production. Projects created with this version cannot be opened by previous Kdenlive releases, and many issues still have to be solved before the official december release.
Windows version updated
Vincent Pinon worked on updating the Windows version to the last stable version (17.08.1) that can be downloaded here: https://files.kde.org/kdenlive/release/Kdenlive-17.08.1-w64.7z.mirrorlist
We hope to improve our packaging soon with the help of some great people in the KDE community, more news will follow on that.

the new time line has a great visual impact, beautiful. Kdenlive 17.12 seems already good, obviously has unexpected closures. When kdenlive crash I did not see the window open automatically to report the bug. Already you can do something, do a good job. On the appimage version for ubuntu tested on a kubuntu 17.4
you can not preview the clips in the project bin. For the rest it seems to turn everything around.
Thank you, kdenlive’s time line has become really beautiful
Video thumbnails in the project bin are not visible only if existing projects made with previous versions of kdenlive are opened. If new projects are created, everything is perfect. The bug reporting window is manual on the help menu. Kdenlive also alpha is great.
As you just released a new Version for Windows aswell, I only wanted to point out, that the download link for the Windows Version in the Download section of your website, still links to the 17.04 Version.
Perhaps you want to change this as you just released the new Version.
And now imma try out the appimage of version 17.12.
I’m really excited.
Keep the good work up and thanks a lot!!!
Updated the link, thanks for pointing it out. Stay tuned for more updates. 🙂
I tried the 17.08.1 on a Windows 10 Desktop and i get the following error (in French):
Impossible d’afficher la fenêtre d’aperçu vidéo
probleme of installation or configuration
And when i close the popup and insert a clip, kdenlive crashes. The environment is correctly set.
I have no problem with the 17.04.03 on this desktop.
The 17.08.1 version also runs correctly on my kubuntu computer
Please report your issue in the bug tracker. Thanks for your help.
OK done Bug 385046
It is due to melt.exe that is on the root folder and must be in share folder. Copying it in share folder makes kdenlive staring correctly.
A new packaging will solve the problem
Thanks! 🙂

Wow, Thank you very much guys! New version looks great and really professional, particularly audio waveform is very useful now.
