GPU-support for upscaling: Which graphics card for Mac Pro 3,1?
Hi All!
My project: Export an existing SD (digibeta) project to 1920×1080 Prores for use in Da Vinci Resolve lite.
As I read, Premiere´s Lanczos Scaling algorithms are available only when a Premiere-compatible CUDA graphics card is installed in the machine, in my case a Mac Pro 3,1. Did anyone test this? Does Lanczos scaling in this case really make a major difference in respect to quality?
There are some discussions about Premiere and GPU support. Adobe gives a list of supported graphics card here – BUT:
– On Mac, the choice seems to boil down to the NVidia GTX 285 and two Quadro cards.
– The 285 is not really available in Germany, only for a too high price (500 Euro). The Quadros are too expensive anyway.So – do you have any recommendations for alternatives? Maybe:
– Just take a GTX 285 for PC and hack the thing, if needed.
– Find another NVidia Card with Mac Drivers, for ex. some people get a GTX 580 to work, which is on Adobe´s list for compatible Windows cards.
– Maybe there is also a another way to upscale (for ex. directly from Resolve in the end)!?Thanks for your help!

There is no support for upscaling with or with out a cuda card.
SD (as in 720×576) will look awfull in HD.
If you want to upscale you need something like Instant HD from Red Giant.———————————————–

Hi Ann.
Thanks for the info.
I had done a test and was halfway OK with the scaling. But of course you are right, there´s nothing like motion estimation involved. Red Giant doesn´t report about their methods. But I´ll give Instant HD a shot; just dl´ed the trial, will report.Talking to a Premiere Pro Expert I have another important question:
When exporting HDV-footage (one part of the project is shot in HDV, mpegs captured with PPro, the rest digibeta) to Prores (HQ), luminance values above 100% are crushed down to 100%.
I tested the files with AJA Kona output from Premiere and FCP. It seems like Premiere doesn´t handle Prores Export that well. With export to Uncompressed the problem is almost solved (there is a slight shift in values, too) but of course the files are huge.
I thought about switching to a Cineform workflow. As I wrote I want to continue working in Da Vinci Resolve Lite.
Cheers,

I cannot answer those questions.
I am on a pc with no third party hardware.
However i do use Cineform from time to time, and its great.———————————————–

So,
did a side-by-side comparison. I still think Premiere´s scaling is quite good! Saying this compared to FCP for ex. but still without CUDA-card installed and therefore without Lanczos-algorithm. But I also agree- Instant HD gives at least the impression of a bit more detail, so could be done. Unfortunately the sharpness it adds also applies to noise in the pictures so seems to be just a spatial contrast enhancer. I still have to test the anti-aliasing feature.Anyway I still don´t know what to do graphics-card wise. Does anyone have experience with CUDA-cards on Premiere on Mac? My original question was which one to choose. I don´t want to order the GTX 285 for Mac from Hong Kong, wait 3 weeks for Christmas just to realize it doesn´t add to my quality any further- being scaled with Instant HD or not.
And- if anyone knows a solution concerning the crushed super-whites in Prores I would be happy, too!
Cheers,
KH
