banding
I have a smoke footage with alpha channel made in AE. In the upper parts where the smoke is “thinning,” I notice some banding. Is that a result of the project being in 8bpc mode? Should I increase to 16 or 32 bpc? The rendered file will be an intermediate file which is going to be edited in Premiere with a delivery format of MPEG2 and is going to be burned in a DVD. If I increase the AE project from 8 bpc to 16 or 32, will the final delivery format in DVD after rendering in Premiere bring back the banding in the smoke? Thanks.

Only works if you render out AE 16bpc in a video codec that supports 16bpc, rendering premiere in 32bpc mode project settings and output(there’s only 8 and 32 weird huh), output of premiere in 16bpc video codec. The banding won’t appear from the master to a mpeg2 9mbps encoding. At least, in theory…
The depth for colors for all of these should say trillions+ of colors.
I’d go Tiff(lzw off) to be short. It’s perfectly lossless and quite small. -
I think the MPEG2 compression will reintroduce the banding. I’d consider adding a bit of noise and doing some test renders.
Search the COW for “banding” and noise”.

Thanks guys. But yes, Steve. My biggest concern is that the banding will be reintroduced after MPEG2 conversion.

If you output to a 8bpc file and add noise to try to hide banding, then yes, a mpeg2 encode will bring it back out again. Computers see even more noise than our eyes do. hence green screening, etc.
