Adding a chroma key filter
on Apr 13, 2009 at 6:29:44 am

In Boris Red 4.3 on a Mac Pro I'm Having a problem
where after I add the chroma key filter to my shot
what I get is an effect where I see my shot and then
it does a page flip and show my plate on the other
side. If I fiddle with the shot for a while I can eventually
make this go away and I get a correct keyed shot.
I have no idea what I'm doing to fix this.

Hi Brian,

Is this happening all the time? What happens if you disable OpenGL previews? You can do this by selecting from the RED pulldown menu: Preview>Open GL Mode>Off.

I hope this helps,

Peter.

Yes it happens every time I add a chroma
key filter. I'll have to check the Open G/L
preview, but the first time I started Boris Red
it told me that my card was not compatable with
Open G/L and was disableing it.

Hi Brian,

Well there are three places in the timeline where you can place the Chroma key, each one delivering a different result.

(1) on top of the track to be keyed
(2) directly on the track but downstream of the track transform function
(3) directly on the track but upstream of the track transform function

Try placing the key in these different positions in the timeline track and let us know what result you are seeing. I hope this helps.

Cheers,

Peter.

What my real problem was/is if you don't
save as the project (running Red from FCP)
before setting up the chroma key (or I think
doing any sort of edit) it does not save the
project file name whereever it keeps it so when
you quit Red and render in FCP it does not use
thoes setting, but rather does what seems to be
a default effect.

Thanks

Brian

Hi Brian,

This is certainly interesting. Just so that I have it straight ... are you pressing the apply button in RED to actually apply the effect to the timeline? If you quit RED instead of pressing the apply button then the result that you describe would be expected.

The correct workflow is:

• apply RED to the clip / transition in FCP
• click the banner to enter RED and edit the effect
• click the Apply button at the lower right of the timeline window, which brings you back to the FCP timeline
• render the FCP timeline

Cheers,

Peter.
