i tried rending as script and with other parameters as well. allways the same problem.
is this a problem with the vertigo filter? i use this filter massive in this clip.

kdenlive Version 0.8.3 (rev. 671c06e)
(built from build-script on 2011-11-18)

thanx,
johannes.

Forums:

i changed the clips a little bit and rendered once again.
now i got a different error message:

when i change the clips in the video (length, position, ...) i get this message on different positions. but rendering never finishes.

thanx,
johannes.

ok. it does look like it is a problem with the frei0r/vertigo filter.
i removed this filter completely from this projects clips. now it renders normally.

are there any suggestions in fixing this problem?

thanx,
johannes.

it might be a problem with the build script. The denoiser filter also has issues because of some compilation flags of the build script. Will look at this when i have time...
