Echoing, repetitive noise in spaces.


I've been using kdnelive for a project for some time, but recently, I've been facing a problem with it's audio rendering.

In the output video if there's a space between 2 audio clips (named x and y, x placed before y in the timeline), then in the rended file, the empty space, instead of being silent repeats the last few milliseconds of the clip x all along the white space. This 'noise' is gone once clip y starts.

Using kdenlive 9.2 with mlt 0.7.8; I also tried 0.8.2 with no difference.

No Rendering when Titles are added !

Hi guys ,

i have been using kdenlive for sometime , recently i installed ubuntu 12.04 and installed kdenlive from software center.

after i add titles (just plain one without any effects) render progress bar goes from 0 to 100% in a flash and output file is 0kb.
but when i remove those titles i get the expected result that is a video without any text titles.

i believe this is something to do with rendering. and i am lost on resolving this.

please help me to get my text titles rendered.

I'm using the latest sunab svn.

When rendering a single 3 second MTS clip to avi or .h264 the waiting time, at the start of render, is about 40 seconds and a single core is running at 100%. When rendering starts it takes about a minute to render. This is so much longer than it used to be, especially on a 6 core 3.2 Ghz machine.

This happened once before, but it sort disappeared after a couple of updates.

Anyone noticed?


Large size of .wmv files


I've got .wmv file with 3 minutes duration. This file has ~12MB size. When I put this video to Kdenlive and render this file (with no changes eg. adding effects etc) with option to .wmv (in render window), file after rendering has ~27MB. When I do the same thing (with the same file) in vegas video, file has ~13MB.

Question: How to reduce this .wmv file size in Kdenlive to have similar file size like in vegas?

Settings of my .wmv codec:
acodec=libmp3lame ab=128k ar=44100 ac=2 vcodec=wmv1 minrate=0 vb=%bitrate+'k' aspect=%dar pass=%passes

Video bitrate from menu: 1000k

No Audio When Rendering with Vorbis Codec

When I render a video to Theora or WebM, there is no included audio track. mplayer says "Audio: no sound" when playing the resulting clip. No errors are reported in the application nor to stdout/stderr.

The audio plays when using the Project Monitor from within the application and rendering to mp4 includes the audio.

I am running Arch Linux with kdenlive 0.9.2. I have all the ladspa plugins available in the repos (cmt, calf, swh) and ffmpeg2theora installed as well.

Slideshow At Wrong FPS

I have a simple animation of 3 seconds at 30fps for a total of 90 frames at 1280x720. I have inspected the files and they are correct. Rendering the animation with mencoder gives the correct animation:

$ mencoder "mf://*.png" -mf type=png:fps=30 -ovc lavc -o output.avi

When I add this into a kdenlive project with the profile "HD 720p 30 fps" as a slideshow, the last few frames of the animation are cut out. The new slideshow dialog shows all frames, selected from the pattern "frame.%04d.png", from frame.0000.png to frame.0089.png, and lists its length at 3 seconds. When I add it to the timeline, it shows as three seconds. Under "Clip Properties" it shows "Duration: 00:00:03:00" and "Frame Duration: 00:00:00:01" - exactly as it should. However, when I render it to any profile, it does not display the last few frames.
