Question

Does PPRO deserve a complete 32bpc color pipline like AE?

hello,

i am learning a lot about 32bpc floating point processing and HDR

and now have this question about PPRO.

AE has a 32bpc color pipeline.  PPRO does not.

Todd Kopriva states from a thread in AE that

If you want to make a feature request for Premiere Pro to have a 32-bpc, high-dynamic-range color pipeline like After Effects, then you can submit a feature request. Be sure to articulate in your feature request why you think an NLE needs a complete 32-bpc, high-dynamic-range color pipeline. Usually, this is only considered important and useful for a compositing and visual effects application, and not as much for an NLE

and to be honest, i don't know whether  NLEs like PPRO should or should not have a COMPLETE 32bpc pipeline.

i would think the more complete the better, unless someone in this forum can explain otherwise.

it probably is more expensive to have PPRO have a COMPLETE 32bpc color pipeline is the only thing i can think of myself.

this situation seems analogous to audio recording:  mix in 24bit, mix down to 16bit...

any advice / info would be appreciated

thanks,

j

Hi there,

Premiere Pro does support 32-bit per channel floating point video throughout the pipeline.  I'm sure Todd was making reference to some certain capability AE has that isn't in PPro, but without seeing the original post, I'm not sure what he was referring to.  However, Premiere Pro has supported 32-bit floating point rendering since version 2.0.

Premiere Pro renders in various pixel formats and depths depending on the input formats, but as a user you can always force 32-bit floating point rendering by checking the Maximum Bit Depth checkbox in the render / export settings.  New in CS5, the Effects panel has various badges to show the capabilities of each effect, so if 32-bit rendering is important to you, you should stick with the effects that have the 32-bit badges.

Regards,

Zac

Zac,

originally i wanted to make a list of all the available 32bpc effects for PPRO and AE

after a little searching and asking, i found out that REvision's effects work as 32bpc for AE

but only 8bpc in PPRO and that adobe controls why it only works in 8bpc

Todd then added that AE has a     COMPLETE   32bpc color pipeline and that PPRO (being a NLE) does not have a COMPLETE 32bpc pipeline

which led to the creation of this thread, asking if PPRO should have a COMPLETE 32bpc pipeline.

i am aware of the 32bpc and yuv badges

i do want to see if i can't find 32bpc effects for the effects i mostly use

because i read that if all of the effects in the sequence aren't 32bpc then the sequence gets rendered at the lowest bpc setting

(UNLESS: you turn on MaxBitDepth (like you said to do) forcing the 32bpc,

but then i also read that noticable differences can be seen in the final output...

thanks for your patience and any other advice...

In your original post, you made reference to a response that you got from the RE:Vision FX guys about how the SDK for Premiere Pro didn't allow them to create 32-bpc plug-ins. You asked why that was the case. I recommended that you bring that question here so that the Premiere Pro SDK folks (such as Zac) could answer that.
