How do you load your node into Image View B? (without dragging it over)
Then I could toggle A and B, like in other software, to see the effect.

Or is there a better way to do this?

There are a few ways to display a tool in the different Viewers. If you prefer keyboard shortcuts, the Viewers are numbered numerically rather than alphabetically. With your tool selected in the Flow, you can use the number keys 1-9 on your keyboard to put the tool into that numbered viewer. In your case where you're referring to A and B, I think those would instead be 1 and 2.

Alternatively, when you hover over a tool in the Flow, you'll see a little black or white dot at the bottom of the tool icon. This is a View Indicator, and there will be the same number of dots as there are Viewers in your UI layout. When the black dot is clicked it will turn white, which indicates that tool is showing in that particular numbered Viewer.

For more details with pictures, you might take a look in the current Fusion user manual on page 153 here: http://documents.blackmagicdesign.com/F ... Manual.pdf

There isn't a hotkey to output to the B views specifically, but it would be a very good thing to have.

Instead, you set the Image View to the B buffer first and then select a node and press 1, 2,... to load images to it. You do the same with A. You can the use the . and , keys to toggle between buffers and compare. / brings up the wipe control.

Thank you. Pieter's technique does work, and helps.

But on the Mac OSX version it doesn't seem to work when a viewer is on the second monitor.

you can save this as a .lua script in the comp script directory, use the hotkey manager to assign a shortcut to it and then it will send the selected node to Viewer1B

Code: Select all

t=composition.ActiveTool
p=composition:GetPreviewList()['Left.B']
o=p:GetConnectedOutput();
if o and o:GetTool() == t then
    t=nil
end
if t and p.View:GetBuffer() == 0 then      -- work around redraw issue when B buffer is hidden
    p.View:SetBuffer(1)
end
p:ViewOn(t)
p.View:Refresh()


you can change the line "Left.B" to "Right.B" and it will work for Viewer2B. any other views will be "View1", "View2", ....
