Log videos in NeatVideo with AfterEffects

Post by Carlomacchiavello » Fri Sep 23, 2016 2:54 pm

From some times i work with After Effects in linearized color space
today i found a strange issue :
i have a log video that are showed correctly in after effects, but if i work in linearized color space are showed darker and contrasted in NV interface.
If i work with linearized space NV interface seems like 709 crushed, and also noise levels are low (1.8-2.1).

the problems are :
- difficult to choose where sample area.
- noise is not correctly and completely removed.
- in some shadow denoised i found strange motion, like waves...

if i disable linearization i can open with NV, read higher noise value (5.1-9) and clean up correctly without error.
my questions are :
- is there a way to read correctly log videos in after effects NV plugin with linearization?
- is there a way to solve correctly denoising also without log viewing in NV interface?

i use NV 4.1.4 under AfterEffects 13.8.1.38 MacOs ElCapitan
composition is 16bit linear in rec709 color space setup.

Do you let Neat Video know that you are working with linear data?
Please check the user guide of Neat Video, page 11 (press F1 while the plug-in window is open) for more details on this.

Thank you,

first i forget that i must tell to NV to work in linear data, if i switch work fine.
sorry, i miss that features.
but... 32bit project take me longer render than a 16 bit composition...
i have video at 12bit raw in, 16 bit could be enought to render out, there isn't a way to enable this option in 16bit project :-D

Neat Video's speed is not very different with 16-bit and 32-bit data. Please check that in Optimize Settings.
