View Full Version : EXR vs EXR Half

It is my understanding that exr is a full 32bit floating point image; which I guess would make exrhalf 16bit?

I ask because I was getting some weirdness in After Effects CS4 from my full EXR renders and my original project settings were set to 16bit color depth. Changed over to 32bit and fixed it.

Standard EXR output in LW 9.6.

Yup, 16bit float though.

I suppose the project settings in AE would be 16-bit integer, not float.

Thanks Mike,

So I guess it would be best to set AE to 32bit regardless of the type of EXR output.

(and yes the 16bit in AE is integer not FP)

Yes. Rendering in 16bit FP usually gives you more than enough data to play with, so there's little need to switch that. But you do need to composite in float as well.
32bit float is faster to process than 16-bit float as well.

Cool. 32bit float is fine -- not struggling with storage space. :D
