1. Re: SG: Different Color rendering in SG-Projects and PPro-Projects?
Dennis Weinmann Dec 6, 2013 1:30 AM (in response to basbebe)Hi,
What you're seeing here is most likely a QT gamma/color shift. It's a Quicktime issue and mostly visible to high compressed QT's (like H.264)
Differences between PR/SG:
PR & SG (in direct link mode) compensates this color/luminance shifts, SG (native) which was used for your EDL doesn't. That's why you're seeing a slight difference when applying a .look to your DSLR clips in PR/SG Direct Link
To remain the same look in your new direct link project you probably have to transcode your H.264 clips to an uncompressed codec (such as QT uncompressed) out of SG, re-link in PR and send again to SG

2. Re: SG: Different Color rendering in SG-Projects and PPro-Projects?

Thanks for your response!
I'm well aware of the so-called Quicktime gamma shift but didn't think of it.
The differences are rather big after applying the look (of course).
If I open the footage in Quicktime (QT 7 with Final Cut Color compatibility enabled to disable ColorSync) it looks like what I'm seeing in Premiere Pro but not like what I'm seeing in the Speedgrade project.
If I open the footage in After Effects with Colormanagement disabled it looks like it does in Quicktime and Premiere Pro / Speedgrade (DirectLink).
So either Speedgrade (in its native mode) is compensating something that isn't there or After Effects, Premiere Pro and Speedgrade via DirectLink are slightly off.
I'm using Direct Link to achieve a more flexible and fluid workflow.
If Premiere Pro had functions similar to AVID when it comes to transcoding timelines (like export all the clips with handles and import / open them in a new timeline) I would think of doing it but the way Premiere is right now I might just add some compensation to the look and keep working with my H.264 footage...
I hope oddities like this will be fixed soon and some urgently needed features added!
