Désolé que je ne peux pas aider plus…I haven’t touched Premiere since 1990s!

Entertainment Technology Debug Question One: What else has changed?

Entertainment Technology Debug Question Two: What else has changed?

Of course, you wonder if DCP O Matic has changed…?

When I google Premiere update color shift – many answers, some recent, many old.

The right color space depends on the capabilities of the equipment that you are using, the client’s release format, and importantly for you, the archive format. A library has value only if it keeps up with current trends. For example, a VHS format and color space has little value today – it is unwatchable and cannot be upgraded easily or well. And more than one streaming service is demanding P3 4K minimum. All trends are toward more and better pixels: How soon 2020? The best that the client can afford today! But you are the client!!! 

The trend in the standards world is toward a high grade mezzanine format for archiving and a lot of metadata for different iterations and evolutions. SMPTE ST2065 – Academy Color Encoding Specification (ACES),and ST 2067 – Interoperable Mastering Format (IMF) detail the entire path from production to various forms of exhibition…and those standards continue to be worked on.

I don’t have a specific answer to “Right Color Space for Premiere” but it seems that the answer is a constantly improving workflow for deliverables that are going to be under constant pressure for better and interchange software that will help advance that.

Hi Flynn,

Thanks for answering.

Except the new Premiere version I haven't change anything. I am even using the same old templates I have used before for other previous  export working fine.

What should be the right color space in premiere ? 


Best regards
Jean

Here below  my sequence setup :

Just wondering, Jean...

Did anything else change in your setup coinciding with the last Premiere version? Monitors? Project parameters?...or perhaps did Premiere change you into a different color space – 709 to P3? Looking at your Tiff files on 2 different P3 screens, they don’t look that different though I can see from the histograms that there are shifts in all the colors.

Thus, I wonder if there are other things going on in the set up.

Hi,

I have been making DCP for a wile and since the last Premiere CC update I have purple artefacts in blue  color.
Does anyone have notice that and know a way to avoid it ?

Are you going into DCP-o-matic with TIFF files?  Do you have TIFFs from the working and non-working versions of Premiere?

Kind regards,
Carl
