Hi,

same issue here with kdenlive 0.8.4. and Debian unstable dist-upgrade today but the resulting file (4 pics, render as webm) works well

How the hell can you have Kdenlive 0.8.4 when we just decided to release Kdenlive 0.8.2 in two weeks.

Its version 0.8-4 and not 0.8.4. Its a slash, not a dot !

I got the same problem here... :/

And here too.

Hm, today I got the update from debian-sid for:
- melt and all libmlt 1:0.7.2+git20110530-0.1
- kdenlive 1:0.8-4.2

With my old saved project from the previous versions I got the rendering crash at the very same 4%.

Then I set up a new (smaller - for testing) project and tried to render it.
The rendering process reached 99% (or maybe 100%), but in the end, I still received the crash error notification.
The rendered mpg2-file seems to be ok.

Later this day, I will try to get my old saved project redone in the new kdenlive version.
Maybe the crash comes from the saved project file ??

I'm a little bit confused, but I will try to go on...

I just notified that i got this bug only when i use the speed effect.

I'm new to the group and am using suse-12.1 on an amd64 machine and an asus g73 portable. Kdenlive 8.2.1 reported the crash as described but it was nonetheless completting the render (very simple projects) on both machines. Since yesterday, with a new project I get no rendering at all, only the annunciation and a 0-byte file size. Both sets of projects revolve around creating training material with an avi file of a guitar note the video part of which is dumped and two png images stretched out to 10-15 seconds to make the new video portion. Very small files, very simple stuff.

With a Ubuntu 12.04, kdenlive 8.2.1 and MLT 7.7, and added effect like speed, I cant finish AVCHD rendering to MPEG2, even one minute chunk ;/ It aborted with message about mlt error, after randomly time... But rendering without any effect works...I also tried different mlt with Kdenlive 8.2.1 and it didnt helped. So I have to wait to next mlt version or refactored Kdenlive version? Or someone solved it?

This is what I,ve got in terminal, when I've ran script:

//STARTING RENDERING: false , false , "/usr/bin/melt" , "atsc_1080p_50" , "avformat" , "-" , "/media/MULTIMEDIA/WIDEO/SONY_HD/2011_03_24_26/PROJEKT/scripts/skrypt002.sh.mlt" , "/media/MULTIMEDIA/WIDEO/SONY_HD/2011_03_24_26/RENDER/Gotowe_poprawione/file.mpg" , () , ("f=mpeg", "acodec=mp2", "ab=384k", "ar=48000", "vcodec=mpeg2video", "minrate=0", "vb=25000k", "bf=2", "b_strategy=1", "trellis=1", "aspect=@16/9", "threads=2", "real_time=-1") , 0 , 8232

"Rendering of /media/MULTIMEDIA/WIDEO/SONY_HD/2011_03_24_26/RENDER/Gotowe_poprawione/file.mpg aborted, resulting video will probably be corrupted."

Also I've used several effects like muting, speed efect, shine efect, volume by keyframes.
