Hi,

I'm new to Kdenlive and have made a short video (2 pictures, one soundfile, roughly 20sec). All works well (except that Kdenlive does not accept mp3 files so I used ogg). I can see the preview and it is like I expected it to be.

But when I start rendering, nothing happens. The progressbar stays with 0% and CPU usage is nothing more that normal, no access to hard drive, no file is created etc.

I am using OpenSuse 11.1 on a Quad CPU system, Kdenlive 0.7.6 and tried several rendering formats - all without any result.

Thanks for any hint!

Hi,

I'm using Kdenlive 0.7.6.
When I click "render to file" the status window appears. Saying "waiting ..." Progess "0%"

On the mp3 file: the "add to project" menue says "xyz.mp3 invalid - remove from project?" But that is no big problem as it works fine with ogg files.

Cheers

I have already tried it.
Can see that a process "melt" is started - as I can see in the shell script- and I can see that this process takes some (minimal) CPU resources (10-20% of one core). That's all.

Do I need a specific kernel version for kdenlive?

I have already tried to reduce the picture size from 2.5 MB to 0.2 MB but the result is the same. Tried to delete the soundtrack but still no rendering result at all.

Hi,

I'm running OpenSuse 11.1 and have installed kdenlive via yast from the packman repository (0.7.6-0.pm.1.8-i586). What is MLT; do I have to install anything else?

Thx

Andreas

MLT is there, latest version from Packman ;-(

Cheers

Instead of doing "Render to file", click on the small arrow besides that button, and it will offer the option to create a render script instead ("Generate script").

Then, in a terminal, try to start that script and check the output..

.. did that before. Here is the result:

//STARTING RENDERING: false , false , "/usr/bin/melt" , "hdv_1080_50i" , "avformat" , "-" , "/home/agrupe/kdenlive/scripts/Skript001.sh.mlt" , "/home/agrupe/Unbenannt.mpg" , () , ("f=mpeg", "acodec=mp2", "ab=384k", "ar=48000", "vcodec=mpeg2video","minrate=0", "b=200k", "bf=2", "b_strategy=1", "trellis=1", "aspect=@16/9") , -1 ,-1
Started render process: "/usr/bin/melt" "/home/agrupe/kdenlive/scripts/Skript001.sh.mlt -profile hdv_1080_50i -consumer avformat:/home/agrupe/Unbenannt.mpg progress=1 f=mpeg acodec=mp2 ab=384k ar=48000 vcodec=mpeg2video minrate=0 b=200k bf=2 b_strategy=1 trellis=1 aspect=@16/9"

It opens a new window where I can see the rendered video (only 2 pictures at the moment) with the transformations I have choosen. The windows keeps open with the last of the 2 pics and that's it. The script never ends, no file (I would expect /home/agrupe/Unbenannt.mpg) is generated.

Thanks for any further help,

Andreas

If it is opening a window, then it seems your MLT FFmpeg plugin is broken or does not exist. Run in a terminal 'melt -query consumers' and see if 'avformat' is there or if it display an error message when trying to load that plugin. If so, contact opensuse about it, or try uninstalling kdenlive, mlt, and ffmpeg and its related libs (libavformat, libavcodec, etc) and then reinstall.

Hi & thanks to all who tried to help me.

Finally I didn't managed to get kdenlife running so I deinstalled it and installed cinelerra where everything worked out of the box without any problems.

Sorry for kdenlife but my goal was to create videos not to debug software;-(

Thanks again

Andreas

I don't know if it fits in here... but I have a problem.

I can render in almost every format now, since I installed everything on that list.
http://kdenlive.org/user-manual/downloading-and-installing-kdenlive/installing-source/installing-required-libraries

The only one missing is, sadly, h264... how can I get it to work?

To render h264, your ffmpeg libs must be built with configure option --enable-libx264.

Ah, good to hear that it's possible.

How can I do that?

If you can't render (the render job stays in the Waiting state forever with 0% progress), make sure you only have one copy of kdenlive running at the time. Two copies running simultaneously can prevent kdenlive from rendering in some cases.
