Thanks you Jonj1611.

Yes it's perfectly stable now. Arround 17mn per frame in HD 1280x720@25fps, on a 16T macpro.

But I think I was in "preview mode" within Vue, wich explain the GR splotches.

Since I went in "Final", looks stable. How stoopid am I? ^^

 

I'll most certainly have to do more testing before finding all the good settups, but for now it is OK. :)

 

C-Ya :)
