Bad representation after Rendern

after rendering in a .avi-file I have in the VLC-player a wrong view.
Do anyone know that problem?
See the last picture on this site. The picture with the stripes.



Capture Video (firewire) with compress mode.

Not sure if I am in the right forum, anyway, here is my problem with Kdenlive.

I connected to firewire without problem, and capture is also without problem, but the problem is the file is too huge. If I have to capture whole 1 hour video, I may need to have about 7 to 8 gig disk space. While I can capture using windows movie maker, for 45 mins, Ionly need about 300 mb. disk space.

render to TIFF sequence crashes

I'm trying export a tiff sequence from kdenlive but get repeated crashes. I created a profile with just vcodec=tiff under parameters. All I get is a single tiff image in the folder, which seems to be corrupt.

Below is the Kdenlive Renderer error log.

(after stop all non-useful program....)
