Are they also visible in ffplay?
(test in terminal "ffplay file.end")

I'm getting this exact same problem too. All the dark areas are getting the exact same white noise in preview and render.

ffplay does NOT show the noise.

MLT: 0.5.4
Kdenlive: Version 0.7.7.1
KDE: 4.4.2
OS: Ubuntu 10.04 (Lucid)
System: x86_64 SMP
Kernel: 2.6.32

I'm looking forward to a fix :) Everything else is working perfectly :)

I got the same white noise problem with dv files. White noise appears in clip / project monitor, and also in files rendered by kdenlive.
I think it's not related to my camera since I noticed the same noise when importing dv files rendered from cinelerra.
ffplay and mplayer can play those files without the white noise.

mlt 0.5.2
kdenlive 0.7.7.1
kde 4.4.2
archlinux x86_64
kernel 2.6.33

I had this problem too on OpenShot... it's a problem in MLT that has been fixed in the latest commit :)

Get MLT v0.5.5 and this problem will go away. Please see this OpenShot bug report (I raised this, but there is instructions later on how to get the latest MLT): https://bugs.launchpad.net/bugs/571954

Also, this is the bug at MLT: http://sourceforge.net/tracker/?func=detail&aid=2972137&group_id=96039&a...

I hope this helps anyone else who sees this issue with kdenlive.

Thanks for fixing this for us ddennedy!
