I will have to work with Alexa footages, full HD codex apple prores. Those footages are really bright and I wonder how to integrate 3D animations or 3D backgrounds from linear rendering of mental Ray xsi (dark one).
In digital fusion, we'll have a LUT , so we could see the final rendering, I could create 3D layers for 2D compositing, there won't be a problem but if I have to make 3D renderings, I 'll have to provide the whole shot (alexa footage with the 3D rendering inside) and I really don't know how to match the color of the 3D (Without the temp LUT). The final color will be in an other studio.
I don't know if I'm really clear and it'll be very helpful if you could suggest a way to process.
Thanks a lot
