To load a clip into the reference area:
1 Select an option from the Reference box.
Storing Reference Frames in the Reference Buffer
You can grab any number of reference frames in the reference area, limited only by framestore space.
To store reference frames in the reference area:
1 Display the frame you want to grab in the viewport.
2 In the Reference Buffer section of the View menu of a tool, click Grab.
The current frame appears in the reference area.
3 To grab another frame, display it in the viewport (or make the changes to the current frame) and then
do one of the following:
■ Press Ctrl+G to replace the current reference frame.
■ Press Ctrl+Shift+G to append the new frame to all existing reference frames.
Cycling Through Multiple Reference Frames
When you work with several frames stored in the reference buffer, you can cycle their display in the reference
area.
To cycle through multiple reference frames:
1 With the split bar on and the reference area showing, click the Prev and Next buttons in the View
menu.
To cycle through multiple reference frames using the reference overlay:
1 Press and hold Ctrl+NUM5 to display the reference overlay.
2 While holding Ctrl, press NUM4 and NUM6 to cycle backwards and forwards through all stored reference
frames.
Displaying Multiple Views
You can display up to four viewports at a time in the image window of most tools. Multiple viewports are
convenient for setting channel values, working in Schematic view, and previewing your results all at the
same time without having to switch views.
NOTE The Resize tool supports two viewports; other tools support up to four viewports.
You can apply a different 3D LUT to each viewport.
