Secondary Monitor Preview Settings

rtbond wrote on 6/24/2008, 6:45 AM

I just connected a 24" 1080p LCD as a secondary display to my system (a refurbished Gateway FPD2485W - $300 @TigerDirect) . Could someone give me some insights into these settings found on the Preview Device tab of the Preferences screen?

Display Mode: Automatic Size Settings vs Use Current Settings
Apply deinterlace filter
Use Color Management / Use Studio RGB

Which of these settings should I be concerned with and why?

In most cases I will be editing HDV content, or a combination of DV and HDV content on the timeline for DVD or BDMV output.

Thanks!

The colour management box is very important if you are doing any colour grading. If you are working in HDV or DV in an 8 bit mode, you will probably want to make sure that "Use Studio RGB" is selected. This will make sure the colours are correctly displayed.

I gather that Vegas handles HDV in Computer RGB when working in 32 bit mode, so you may wish to uncheck that box in those circumstances.

To add onto Robert's comment, in 32-bit mode the DV footage will decode to studio RGB and the HDV stuff to computer RGB. I would convert all the DV footage to computer RGB by adding studio-->computer RGB color corrector or levels presets (make sure compositing gamma is 2.222).
In the secondary monitor settings, uncheck the studio RGB box (or uncheck the color management box).

I have discovered that with "Use Studio RGB" selected in a 8-bit project I get over-exposed whites, whereas de-selecting this secondary display Preview Device color management option eliminates the washed out look.

The timeline content is DV and HDV content.

So, what am I missing? The secondary display is a Gateway FPD2485W, which I have done nothing to calibrate in any way (perhaps I need to?)

Thanks!

That's because those whites are overexposed whites. Most (all?) DV cameras will record values above white level... you can correct those values down into legal range if you'd like.

The "on the level" and "Color spaces " articles might be of use.

Thanks Glenn. I'll take a look at the linked articles.

So what exactly is the "Use Studio RGB" color management option doing? <i..e. what is it intended application> It appears to require that your footage is already Studio RGB range compliant, which is not necessarily the case with DV (and HDV?) footage.

Also, should applying the Sony Broadcast Colors FX to the video track force the secondary monitor preview to be in the Studio RGB range? I did try inserting this FX but did not see any change in the overexposed preview ( "Use Studio RGB" color management enabled on the secondary display), but perhaps I needed to play with the FX settings to see a change?

Thanks!
