I'm using kdenlive on a manjaro machine and I love it but have a big problem is almost impossible to work because it chashes 2-3 times per hour. I'm using an AUR version (15.09) because the the normal (extra) version was completely impossible to work. I'm using it on a lenovo t430 with ssd. There is no padron for the crashes, it crashes when ever it wants. Is there anything I can do to get it better ? Is it only on manjaro ? Please help.

Thanks,

Afonso

you're not alone.

Kdenlive has taken quite a big drop in stability recently. VERY much looking forward to seeing a more stable version.

You could try an older version? It was working ok a few months back. Not sure where you'd get an older version sorry.

I don't have any experience using old packages with Manjaro, but the version of kdenlive you'll want is 0.9.10, the lack of stability is to do with a move from using kde4 libraries to kde5. In fact, kind of wish they'd just stuck with kde4 stuff, but the move would have to happen eventually I guess, and I hope it will stabilise again soon.

It was a bit of a pain rolling back to kdenlive-0.9.10 with Tumbleweed as other bits were compiled against kde5 and needed replacing (mlt and frie0r-plugins).

Sorry I couldn't be more help :/

Thanks a lot you all. It really help because I was think what I was doing wrong or if it was a problem of manjaro/archlinux because they tend to be blending edge. Now I know that it is a problem of kdenlive and it is a pitty because I like it very much. I think I'm going to try alternatives like openshot or shotcut. I think that kdenlive is better, as far as know but until is more stable I think I will use the alternatives.
Thanks for the responses.

Kdenlive 15.8.* is the stable branch, even if based on KF5.
We had a problem in 15.8.2 (october release), but normally 15.8.3 should be fine for normal work (tagged last week, archives from yesterday).
15.9 is the development branch, but it should become a release within 1 month, so we would appreciate very much feedback from you alpha tester
If you identify a crash condition, please reproduce it in gdb and send the backtrace. Sometimes the problem can be in ffmpeg/mlt (eg recent memory leak & wrong composite+alpha operations)...
Note: we are aware that we have problems with titles in Qt5 but very tricky and didn't find a fix yet.

vpinion, which MLT version has the memory leak problem? I'm asking because I have seen such a leak in MLT with four or five affine/composition transitions at the same time in a larger project. Is there a fixed stable MLT available or only dev MLT?

vpinon I was using 15.8.2 but was impossible to work so after to try to fix it with tips from forum on manjaro I decided to try the aur one (15.9). It is better but it crashes 2-3 times per hour. I would apreciate to help but I can't isolate when it crashes. It crashes when I'm moving clip on timeline, when I tryed to apply transitions or effects etc
When the version 15.8.3 arrives to the repository I will try it and tell you how it works.

Thanks a lot you all.

TheDiveO: Dan doesn't release MLT so often, so building the dev MLT is sometimes necessary to get the latest fix.
If there is a problem with composite, that can be an issue with 15.9 as there are automatic composite transitions on every track...
amadlopes: if no DrKonqi offers to crate backtrace, then you could run "gdb kdenlive" then "run", and "bt" after the crash, and paste the output to pastebin...

Yeah, sorry, I don't mean to suggest that kdenlive-0.9 is the stable branch, just that in terms of stability I find it's more solid than current kdenlive.

For production I'm keeping with the branch "Applications/15.08" at this time. There should not be any automatic composite transitions then, right?

I have the same problem on my second laptop running manjaro: there is no kdenlive 0.9.8x available anymore through the AUR .... if anybody can point me to how to get kdenlive 0.9.8.10 run on manjaro that would be fantastic

If you can use Archlinux packages (you mentioned AUR), you will find the old versions of kdenlive (and any other package) here:
http://seblu.net/a/archive/packages/k/kdenlive/

But you will have to take care of the dependencies by yourself.

I just would like to confirm that in my experience, 15.08.3 is rather stable on Arch Linux 64bit with AMD Catalyst graphics drivers.

Yes, I've found now that I had the opportunity to try out kdenlive-15.08.3 with a new project, I have found it to be stable enough for proper use.

A few bugs present that weren't in kdenlive-0.9, but nothing show stopping and I imagine they'll go away soon. (even sooner once I get the time to report them all properly).

good to know, thanks! I ll give it another shot!

problem here is: manjaro works perfectly with dual monitor desktop with the nouveau drivers and horrible performance with the proprietary drivers, so i cant really use them to please kdenlive
