Bits

[Anonymous]

hello…

I have a lot of troubles with bits…. 🙁

We can work with 8, 10, etc bits… How to choose the right value of the bits that I will work with? And how to choose the number of the bits that I will export my project?

regards,
mario

if you are working with NTSC/PAL (video for that matter) 8 bits is the depth these formats support.

but if your compositing is for film then you should consider deeper depths. 10-12 twelve bits per channel would allow for a greater color resolution when film is projected. though the deeper depths bring with it conversion issues, like 10bit logarithmic or 12 bit linear. i am not involved with combustion but, if you are working with film res images you should consult the scanning service, because they would be supplying the image format. i found out (the hard way) that cineon files should be converted to a proper bit depth by the compositor (that’s me) depending on the footage and requirements of the project.

i also am fairly new to bigger bit depths, but if you are concerned over file sizes and processing times, 8 bits is okay if you are not working on something that is not going to be transferred to film.

hope this helps…
