Spyder2Express & CS5 ??

[George D.]

Is there any problem whatsoever in using Spyder2Expresss to calibrate a monitor when using Adobe Premier CS5 ?

In other words, does it interfere with the color renditions and color management created by CS5 ?

If so, what would be the best way to keep accurate colors calibrated ?

Thanks.

I've done this several times. Are you talking about the graphics card output/overlay or a dedicated SDI/HDMI signal?

It's a dedicated SDI/HDMI signal, but I don't understand what difference that would make.

I have a spyder2pro (and I believe the difference is the software) and it's designed for profiling your computer monitor.

But you can use them with the likes of Calman to calibrate your video monitor; on top of this I use my to calibrate the video overlay on the computer monitor too.

I was just trying to ascertain your calibration path.

Premiere Pro assumes your monitoring in sRGB (Unless you are going out through a piece of hardware like BM, AJA, DV etc). All footage gets translated (in real time) to sRGB when you view it in your program monitor.

Sorry for my ignorance on this, but exactly HOW do I calibrate my monitor to sRGB ?

What I did is apply a REC709 2.2 gamma, D65: calibration to the system; the video overlay assumes the REC709 (as it's VMR).

I'm sure it's not super accurate but it's worked for me.

Actually I discovered something else which throws a bit of a spanner in the works and not entirely unexpected. PP doesn't pass anything below 17,17,17 RGB or 236,236,236 on its overlay and there is no way to adjust it on the surface. This is not a complete disaster but means something fishy is going on in video overlay.

I guess this is why people reach for AJA cards so they can have a true 'broadcast' output.

So things are being clipped on the overlay; well it's not ideal but at the moment I don't have a solution. But I will check the second system we've got on CS4 with different drivers.

It is not PPro. If you have a NVidia card you can change this. Go to NVidia Control Panel and select "Video -> Adjust Video Color Settings". Then hit "Advanced" from the right bottom part and set "Dynamic range: Full (0-255)".

Thanks I tried this but pp uses its own player which doesn't access the nvidia video overlay controls. At least on my system, have you checked this on yours?

That is sRGB rec.709 has the same color primaries as sRGB but is gamma 2.2 and d65 color temprature.
