slow merge

Post by bartek_zgo »

Hi Guys,
we are trying to optimize render time. We are currently analyzing merge process. We start render on 2 machines. Each one creates flm file. Than we call

Code: Select all

film1 = Film::Create(fistFilmPath);
film2 = Film::Create(secondFilmPath);
film1->AddFilm(film2);
film1->SaveOutput("out.exr");
For image with restitution 4000x2000 it takes more than 7 minutes. The first part, is loading files and calling AddFilm takes about 27s. Than the SaveOutput command start OIDN and this part takes about 6 minutes. Is it normal?

Code: Select all
