On two different computer under ubuntu 17.04 and appimage of version 1704 or 1704-1, i have a crash and this log every time i load a clip in the project…
It’s work fine with 16.. version.

Awesome I love the progress, and good luck with the refactoring. It’s hard work I know
Hi, just to inform that before the last update on ubuntu 16.04, version of the kdenlive team ppa, there is no more segfault when I click on an affine or composite transition. What a relief !
The focus on the privacy invading and dangerous Windows operating system does burn a lot of energy and is an offense to people who supported this project via crowdfunding or via other ways to get better video editing on a free software operating systems.
KDEnlive today still is no stable software for real life editing, the developers do not seem to be able to deliver a reliable software that creative workers could depend on – major important features are missing (e.g. multicam editing, GPU support, OFX plugin support, workflow roundtrips to other editing softwares) and there is no clear understanding of how important stability for this kind of software is.
If you are a serious media creator and have already discovered the extraordinary stability and un-bloatedness of Linux and you are in search for a video editing software that you can rely on – look at Lightworks – it is not open source, like once promised, but it is a very professional and absolutely reliable editing software.
KDEnlive should be seen as some private experiment and the developers should put a big warning on their website – you will get BURNED when you are considering this broken and unstable code for serious work, so do not ever use it if your time is precious! I lost lots of hours trying to WORK with KDEnlive – no progress!
After many versions and many years of patience I am totally fed up now with this project. These kind of half-assed development efforts do hurt the open source movement and have a very negative impact and should be deleted – the developers have absolutely no clue what kind of responsibility they take by publishing a multimedia software product and how much pain they are causing by not being able to deliver stability for many years now – do not waste your time here!
Blender is a fantastic example of a free software project that not only works flawlessly, but is also very successfully and professionally used by serious multimedia artists. That kind of projects, however, have two things in common: very competent and committed developers and people with a clear vision for their project. It would be great if KDEnlive could find such people, but I believe it is to late now, they burned their credibility completely in the last years. This project should be rebooted with a different team and a different name.
First of all it is a shame that you don’t have courage to use your real identity to do some ranting, don’t be afraid we don’t bite… anyway it says a lot about your character.
This is a community project and the devs and members donate their time to work on something we like. If you don’t like what we are trying to do then you can leave and be happy using another software or you can give some constructive input/feedback on what happened that made you angry so the devs can fix it. Basically we are building the tool we want, if you want to participate we are happy to have you, but if you don’t have patience go get an off the shelf program that suits you. Just don’t come with your pitchfork here insulting the hard work of people.
Seems that Kdenlive gains momentum, and with momentum comes, well … long rants, vanity, the complete circus. It’ll pass though. So let’s work on our media projects and enjoy Kdenlive, while some are busy posting.
I can understand people might sometimes get frustrated that something doesn’t work the way they want/expect but they should also have the maturity to know how to pinpoint their problem and try to fix it. Many programs pass through this rage such as Gimp, Inkscape, Scribus, Blender, Shotcut, etc. We’ll keep editing while haters… 🙂
Well… I do not share these experiences. I’ve edited several promotional videos with KDEnlive (professionally) and I did not run into any of these issues. Despite having some distance to go before you can compare it against FCP or AP, it is VERY powerful software. And despite preference, one can edit professional videos with it.
Now for the other complaint… Windows. Having a Windows version of your software is a good thing. Back in the day, when I hated Microsoft with a vengeance, I found it almost impossible to switch because of having to learn all this new software.
The fact that there were also Windows versions of GIMP, Blender, OpenOffice, and Inkscape made all the difference. I could replace my programs one by one, instead of all at once, while still having the ability to fall back on my Windows only programs when I my knowledge of the new software was still limited.
And… welcome to life! Where things are sometimes not as expected.
Recognize and appreciate time, energy and hard work. Especially of others.
I use Kdenlive often and of course the 17.04.x version is unstable for me, I think it needs some bugfix. But the previous one (16.12.3) was very stable and I still work with that. Obviously I’m talking about the Linux version cause the Windows one is like a beta.
Always crash when load effect preset
1. add color clip
2. add title clip
3. add transform effect to title clip
4. save preset
5. add new title clip
6. add transform effect, apply preset (4)
7. crash and restart application
8. and how to delete preset? when choosing preset kdenlive always crash
Hi please use the forums, mailing list or g+ community for help.
My initial comment was not directed to the devs and I have no intention to insult you, it is very sad that the factual description of a different perspective – the one of the software user – makes you feel like that.
Fact is: KDEnlive was never stable or usable for serious work – also it is unclear, why many attempts to make things better never worked out and why there are so many other projects that deliver something usable after a much shorter time.
I was addressing creative people that just came here and hoped to find something usable – it should be a warning! Serious damage has happened by using this software and lots of time was spent trying to be patient over and over again with this project for some years – a senseless waste of time!
Again, dear fellow creative friends, if your time is precious, go ahead! This project is just a peacocky game by some code-narcists, the voiced user-perspective is just “haters hating”.
Regarding my name: I am nobody and everybody, your shadow and your mirror, your curse and your blessing.
I am not a dev! I am a user and community member who likes to give back to a tool I use professionally (as in to pay the rent). Here is my portfolio: vimeo.com/gunga
So yes, I repeat that you are a hater. That is not a way to solve any problem (I truly hope that you are not like this in real life.) Accept a friendly advice and go be happy with another tool. 🙂
Am I able to download this as a .zip file?
Here you can find how to obtain Kdenlive: https://kdenlive.org/download/
I am wondering if any work is being done toward completing the multi-camera functionality. It might not be as difficult as it might first seem. In Adobe Premiere pro, it seems to me that all the software does while the user edits the multi-camera sequence is to record the timing and nature of the cuts made. After that, when the session is complete, the software then inserts the cuts at their proper place. Certainly there’s something more going on than that, but I really think this is doable.
Currently all efforts are focused on refactoring the timeline code to lay the groundwork for features as advanced trimming tools and single track transitions. Multicam editing is in the roadmap but not a priority at the moment. Unfortunately there is not enough (wo)man power to have so many features at once. So you are welcome to contribute if you can. 🙂
So, as I was looking for an opensource video editor for windows once again, I stumbled on kdenlive a couple days ago. It didn’t exist the last time I looked for one.
I’m quite happy it does now because it’s very promising. Sure it may lack some features and some things are not as stable as can be right now, but it is very accessible for a beginner like me and seems to pack most of the needed features.
I have to say that I would be delighted if we could set the output format with a bit more flexibility without having to create a custom preset with command files though. Maybe later, as it could be for supporting gpu encoding acceleration using opencl for example.
Thanks guys, keep up the good work.
Crop, scale and tilt doesnt work,
when apply to track previews become blank black.
cropdetect, rotate and many more effect..
scroll bar value running like crazy
Kdenlive : Version 17.04.1
Please ask in our Forum for help so we can diagnose what’s wrong with your setup. Thank you for your cooperation.
exactly the same problem on Ubuntu 16.04, running in virtual box
I actually ran into this problem too. The crop, scale, and tilt would turn the monitor black but other effects work fine. Here is what I found: when adding the crop, scale, and tilt the tilt x and tilt y parameters go to max. This literally pushes the image off of the monitor. However if you manually calibrate the x and y tilt you can bring the image back. Hopefully this helps.
tried the vaapi re-encoding but apparently ffmpeg fails with it quite a bit at least on my skylake cpu ;/
it doesnt like ‘-hwaccel_output_format vaapi’ which is like, most of the actual gain..

ich hoffe mir kann hier jemand helfen. Ich nutze seit einigen Jahren Kdenlive als Standardprogramm. Doch leider stürzt mir immer der DVD-Assistent ab, in der Fehlermeldung steht immer das keine DVD-Struktur erstellt werden kann.
Ich digitalisiere sehr oft VHS-Videokassetten. Und bis jetzt konnte ich nur über Umwege die Daten auf DVD brennen. Da aber der DVD-Autor immer abstürzt konnte ich bisher keine DVD mit DVD-Menü erstellen.
vielen Dank schon mal.
