By the way, what versions of kdenlive, mlt do you use?

MLT: 5.0
KdeNlive: 0.7.8
Fedora 12
Proc intel i7 quad
ram: 8GB

Please help :(
It looks exacly like he raport

I try other files like 'avi' but thouse white dots are visible only on black fileds on 'mov' files from Canon 7D

White dots are also visible on Kino in KDE on fedora 12.

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 :)

Reminder to all, there is an open bug on this.

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&atid=613414

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

Thanks for fixing this for us ddennedy!
