I am not sure if the next one is a bug or what, but surely I would like to dig a bit into the details.
Here is a copy of the ticket I sent to RL, on behalf of general understanding/information.
Here we go...

I have a pretty much complex project and I wish to create a preview, rendering "in toto". i.e. about 18000 frames.

I went for AVI uncompressed 1980x1080.
If I choose the Render Quality = Final Render and leave the Super Sampling and High Quality Shadow unchecked, the render completes with no crash.
But as soon as I enable one of these settings, after a certain time, IC crashes during the rendering.
If I render a shorter section (e.g. 3000 frames), the rendering does not crashes even with these options checked.
This means that the probability of a crash seems to proportional to the length of the video being rendered.

So, my question is: what kind of resources do these options need ?
More RAM ? I have 16GB... not enough ?
More CPU power ? I have a i7-4970 8-core processor @3.6GHz
More power on a video card ? I have the Nvidia GTX980 with 4GB RAM...

The online manual says pretty much nothing about these controls. That is all of what we have: "You may enable the Super Sampling and/or High Quality Shadow boxes to enhance the quality of the exported media."

If anyone has some more information, I would appreciate if it could be shared.

Cheers

Roberto
