Hi everybody, a few days ago I sent a bug report on Mantis usr: grangorge http://www.kdenlive.org/mantis/view.php?id=2489 , to report this issue, Kdenlive stopped rendering suddenly, not a single format works. Now the thing is getting stranger.
I was on the way to re-install kubuntu from scratch to a new partition on my drive, and so I did.
After finishing clean install, I installed Kdenlive from source and I got the same effect as old installation on old system, kdenlive can't render to any format, and I've tried them all.

Since I think it's a strange issue and sow that other users have the same problem, I wanted to post it here also.

Again all details in this bug report: http://www.kdenlive.org/mantis/view.php?id=2489

You know, funny thing is that kdenlive works perfectly, just can't render although mlt, ffmpeg and all libraries are up to date.

Other funny thing kdenlive works perfectly and renders also perfectly on my laptop (Lenovo B-550, intel graphics, 3gb ram, 320 hd) but there kdenlive 0.7.8 and MLT 0.7.6.

Any hint?

Hope this could help some other.

PLZ I want to keep on working with KDE and Kdenlive, I don't want to buy a MAC!

Thanks.

From your bug report:

"Rendering of /home/gianni/Gianni /Foto/Nuvole_Fumo/Fumo/FumoBosco1-640x398Flashes1-Test.mp4 aborted, resulting video will probably be corrupted."

You could try rendering to "/home/gianni/Gianni /" location without the space after /Gianni and see if that helps.

thanks for the answer but That's just an example, of course I've tried with several files all with different names and destinations.

Yep, exactly same problem and same history.
Also me I tried videos I had already rendered few days ago to no avail.
I think is becoming common issue, since we also have same configuration.

Yes same here on Ubuntu 11.10 64bit + sunabs git build.

Rendering fails, exporting a script and running that fails but using melt to play the script.mlt file works but trying to use melt to encode with the script.mlt causes an error about unable to load custom profile from ~/.kde/share/apps/kdenlive/profiles, so a problem with MLT by the looks.

News:

Had to downgrade to Kdenlive 0.8.2 and MLT 0.7.6 and voilà! not yet perfect but at least rendering works again!

Procedure: uninstall completely kdenlive and mlt delete or better move to a safe place and delete later, also kdenliverc file (.kde/share/config/kdenliverc), download packages directly (kdenlive-0.8.2.1.tar.gz and mlt-0.7.6.tar.gz from respective sites) and re-install from terminal (extract archives and you'll find install information there). Maybe you'll have some libraries missing but you can manually add them later. (This works for Kubuntu 11.10 KDE 4.7.4)

At the moment it's working, hope It'll keep on going.

Hope this could help someone.

I had to downgrade from the svn-repo to ppa:sunab/kdenlive-release too. I purged all kdenlive and melt packages bevore I installed the "stable" kdenlive.

Just a question - you did check that the result is not there and/or broken?
I also get this message when rendering, but it's only after the rendering is finished, some cleanup-error (in mlt IIRC). But for me, the files are there and OK.

The rendering issue is now confirmed and discussed on MLT's mailing list, should be fixed quickly. I can also confirm the transition keyframe issue, working on it right now.

I am running ubunto 11.10 64 bit
I admit trying the svn-repo ppa:sunab/kdenlive-release with kdenlive 8.3 and loved it very much - I made a few test of the image stabilization
and no problems rendering out. I Also aded the sysfigstudio as part of my future workplace.

- I was so happy and ready to use kdenlive for my projects - the 8.2.1 was OK stable but the new features like easy voice over recording and image stabilization, transcoding is just perfekt and so nice - so maybe just messing a nice way to sync simular audio tracks with a video track because I use a canon 500D and sometimes external sound recording or another camera were synkronisation on a simular sound would be nice to allign events/views from two cameras.

Anyway I can't complain and Think you are making so great software - I have been using pineaple studio from 9 to 15 for years now on windows but this
have to stop with lack of tracks and the creative solutions needs upgradesand you can even be sure the old project you have made in 12 is possibæe
to render on version 15 etc. Also I am a linux user so I am not very happy to be forced to use windows.

Maybe it was stupid of me to tryout version 8.3 - but It made me happy to see where things are going.

My problems with rendering was there the next day - I have tryid to uninstall some packages and reinstall, even to go back to 8.2.1 but currently
I have even a problem to get the 8.2.1 t back and doing rendering - I did uninstall about 11 repository packages and made the 8.2.1 work again
but both the 8.2.1 and the new 8.3 is working its just the rendering thats does not work for me currently.

I was on the irc hoping for suggestions for debugging my problem, but I understand I am not alone with this.

Best regards from Denmark

- Well I removed openshot kdenlive python-mlt3 ubuntustudio-video libmlt4
Also I marked not to use the kdenlive-svn - so doing and update and install of the ppa:sunab/kdenlive-release it was working again using 8.2.1 but I
really look forward to this 8.3 ;-) I don't know if it would be possible to use the 8.3 but with current melt version or if the image stabilzation and voice recoding option would work.

But I am so ready to be a steady kdenlive user.

Still having same problems with the latest update. sunabs-svn

Me too, recent projects are freezing kdenlive although starting new projects doesn't. Added a bug report. Haven't needed to render yet so is rendering still a problem?

I can create new projects, and I can edit existing/recent projects.
But rendering is a problem for me.

Yesterday Kdenlive froze when I tried rendering, and I had to restart the computer to close Kdenlive.
Today, after a system update, Kdenlive chrashes when I try rendering.

Don't know whether this helps anybody analyzing the problem.

Ubuntu 11.10 - 64 bit
Kdenlive 0.3.8

0.8.3 .........
