Can I render .exr file as log from Baselight

[Soumitra Sarkar]

Can I render .openExr file  from Baselight like log because my vfx vendors want to log file. Also I have to render  only cg. exr files and grade have to done in some where else. So we can't do BaseGrade for vfx render.plz help with giving the scene and render setting  for. Exr( log ) render. Although as I know .exr File itself linear file.

Use the ACES or FilmLight scene template. Put the footage into the timeline and use 'Automatic' or 'From Metadata' tagging for the Input Colour Space. Then on the render page select the desired log output colour space.

There is nothing stopping you from rendering a log colour space into exr files. But a 10bit dpx will give you more image quality than exr in this case. Best would be rendering to 16bit dpx (for log colour spaces).

When you render a log colour space into exr, you might see banding in the image.

Ok, sir... Thank you. But some other software like assimitate Scratch can't  give any banding in Image in log space. exr file

[Andy Minuth]

Yes, if there is enough noise in the images the banding is masked by the noise.

Great to see you pop by the forum once in a while @Andy Minuth. How about you and Lowepost agree on doing a Baselight course? 💥
