well and here is the strange thing. i thought it was the codec at first. but then i rendered two 5 second test videos to post here on the forum. one in apple pro res 422 hq and one in the original dnx hd 180 codec.
when i tested the footage the effect applied to both videos.
when i tried the full movie it did not work.

so it has to be a problem with the size.
i have split the video in 30 second segments now and i can use the effect on the footage.
so i found a workaround.
but it is not very confortable especially if i would get a longer video from the same people.

even more strange is that i never had a problem using the effect on longer videos. i tried a test on a 15 minute video coded in apple pro res 4444 with 26gb in size and the effect worked without problem.

however it is rendering now 😉

yes i know that…

Oh sorry i am working with the german version. yes its remve grain.

i´ve done some more tests now and rendered two small samples to post here. but with these samples the effect works just great. but it does not wor with the entire film. so i thought the file might be too big. but then i imported a apple pro res 4444 file with 26gb from a former project and the effect had no problem with this one… i just do not understand where the problem is.

I do not know much about the manual distribution of the samples. i tried it now. but with no effect.
i had the effect applied on the original layer and tried it on a adjustment layer too. and i rendered the movie and treid the effect on the mivie. also no effect… 🙁

I tried several approaches. i had the effect on the layer. i had the effect on an adjustment layer and i rendered the movie with the color correction and tried to apply the effect as the only one on the rendered movie.

all these methods had no effect. the noise reduction just does not apply.
if i enable the unsharp mask then the footage is sharpened normally. so the noise reduction is the only thing that does not work.

i really cannot put my finger on this one… on all other footage i have got the effects applies normally. i guess it must have something to do with the codec.

thank you for the link. this solved my performance problems with the mac. looks like i have to install a lot more ram to get more processors to render….
