Premiere's 'maximum bit depth' check-box at DVinfo.net

Graham Hickling · January 20th, 2009, 01:36 AM

Having recently moved from Aspect to Prospect, I'm still getting my head around the whole 16-bit vs. 8-bit thing.

Premiere has a "max bit depth" checkbox under Project/Render settings, which is unchecked by default. So .... if I create a default Cineform project, edit and then render will I get an 8-bit file, unless I check that box in which case I'll instead get a 16-bit one? Am I understanding that correctly?

That control open applies for non-CineForm exports. We use the Playback Settings control to select 32-bit float vs 8-bit RGB.

along those same lines......are there any specific effects that we need to choose? Obviously the Cineform ones but are there any Adobe specific filters that are better than others? I also use Magic Bullet presets and Colorista....are these 10bit or better?

I know Magic Bullet was planning a 32-bit version, not sure if is was released. Prospect will tell you if a filter is 32-bit or only 8-bit, just turn that control on within the playback settings.

David, help me understand a little more. I am on Premiere CS4, using NeoHD, so I always select DESKTOP as my editing mode.

Once I upgrade to the V4 NeoHD, if I select on the SEQUENCE Menu "Maximum bit Depth" do I get 32bit processing using Neo and Adobe affects and Transistions (I know only a few of Adobe's are 32bit).

Also, what about when we export via Adobe Media Encoder in CS4. I assume we will be able to choose AVI and select Cineform as the codec. There is a "render at maximum Depth" check box in the new Adobe Encoder. Will this be necessary or will it look only at the Sequence Settings check box.

Thanks in advance. I am really looking forward to the CS4 versions of your products.

NEO HD/4K is only a 32-bit importer/exporter under Premiere, everything else is under Adobe's control, so the question might be better for Adobe (or do some experiments.) When using Prospect HD/4K CineForm controls more of the high precision math.
