Croping in Boris Red from final cut pro

Hi All,
I'm a new Boris user and I'm trying to key a shot
and want to crop out lights at the top of the frame.
According to the manual you can click on a lock
icon in the interface so you can independently set
the top, left, etc. I don't see how to do this in the
FCP interface for Boris.

Thanks

Brain

Hi Brian,

You can achieve this in a couple of different ways. You can use the crop tools in the controls window, which will provide you with a straight crop or you can use a spline mask to create a garbage mask. I'd suggest the latter as it's a far more flexible approach.

Here are the steps:

• apply RED to track that you want to key in FCP
• enter the RED UI by clicking on the RED banner in the controls window
• apply the Chroma Key filter to the track
• tweak the keyer to eliminate the background screen
• twirl down the keyed track - this reveals the mask sub-track
• click on the mask track in the timeline
• make sure the tools window is open (if not select window>show tool window)
• click on the pen tool
• generate a spline on the mask track by clicking and dragging in the composite window - click on the first point to close the spline
• there is an invert mask button on the mask track - red circle on a rectangle next to the eyeball - and you may need to click this to invert the mask so that it knocks out the element that you need remove.

I hope this helps.

Peter.

Almost forgot to explain the crop function for you. :)

The crop tool is locked by default to crop all edges uniformly. To create a non-uniform crop you first need to unlock the sides from each other.

• click on the lock icon to unlock
• set all sides to hold interpolation by clicking in the interpolation selector box and choosing hold

Now you can move any of the sides independently to generate non-uniform crops.

Hope this helps,

Peter.

The problem is that I can't find the lock
icon. When I have a chance I will try the spline
though. Thank you.

The lock icon should be located on the Crop Tab in the Controls Window. There are two of them ... one for distance (crop) and one for smoothness (feather). The icon looks like a padlock. If you're using RED 3 then you may need to scroll the Controls Window to access that tab.

I hope this helps.

Peter.
