Camera Specs: How change a 16/9 camera render to other ratio? New in the blender community, i've got one question about the camera settings.
Here's my problem, in order to do video mapping on stage for an event, i would like to do a render of my scene in an aspect ratio of 16/10 and not 16/9 (default).

I use the camera on blender as my video projector would stand in real at the event.

Maybe i should use an internal ratio directly on my graphic card, or maybe there is settings that i don't see in blender ?

Hope my english's fine,
Hope that you got answers

Thanks
Go to the Properties Panel and open the Render Tab.

Locate the Dimensions Panel. You can set the aspect ratio by setting the X and Y resultion of the image.

For a 16:10 aspect ratio, you could choose the following dimensions: 1920 x 1200.
