Convert 601 color space to 709 in CS4 ?

[Vince Becquiot]

Hi Ninetto,

That’s one of the issue going from SD to HD. I don’t know of any tools that will to do that for you in Premiere. We usually do it on the fly, but yes, you will need a calibrated monitor.

If you need to convert from one color space to another and you have After Effects, come on over to the After Effects forum, and we can help you over there.

I would check that you don’t have a problem with “setup” being [mistakenly] embedded in the SD material. I could be wrong, but I’m pretty sure digital black is zero in both colorspaces…

Thanks much for the advice.
Over at the AE Forum they have advised the following workflow:

1)Make sure imported material is interpreted as correct color profile, i.e. in my case I have RGB uncompressed AVIs.

2) Set up HD Composition with 709 color space and drop material into comp.

This all almost seems too easy for me, that AE/Adobe is intelligent enough to convert the color space accurately. I will be exporting to blu-ray so only then will I see if the translations really works as almost “auto-pilot”.

I am aware that sometimes rookie editors ignore the color profiles of projects they export, so I have to verifiy the uncompressed AVIs indeed are Adobe RGB profiles, I have no desire to color corrected all their stuff for free!

Anyone else have experience with this?

The color management features introduced in After Effects 7 and refined in CS3 and CS4 were created entirely to make this kind of work easy for you (though not for our engineers).

I’ll check in on the After Effects thread, but the instructions that you recounted are a little off. The gist is this:

1) Enable color management for the project.
2) Import your footage, amking sure that it’s interpreted as 601.
3) Render and export, specifying 709 as the output color space.

That’s really it.
