Slipping a Reference Image
Previewing a Reveal Operation Using a Reference Image
Overlaying
a reference image on the result offers an intuitive way of previewing paint
operations.
When you overlay a source onto the result, you
can preview the effects of a Reveal operation. The selected image
is superimposed over the result, and the transparency can be adjusted.
This allows you to see exactly what your brush strokes will reveal.
When you overlay a result reference clip onto
the result, you can slip the overlaid frame to display previous
or next frames, creating an onion skin effect.
The overlay of the front and the matte can also
be shown on the result, allowing you to rotoscope more easily, for
example.
To
display the reference image:
- Enable
the Overlay button (Tab).
The reference image appears by default at 50%
transparency.
- Select
the reference image you want to display from the Reference box.
- If
you selected Source Matte or Source Front, select an image from
the Sources list.
- With
the reference image, you can:
- Hold
down Ctrl+Shift and drag the source front
or source matte to offset it to preview a Reveal operation.
- Scale
the image, by entering a value in the Scale field.
- Rotate
the image, by entering the angle of rotation in the Rotate field.
- Set
the Slip value in the Sources list to show a reference image at a
different frame relative to the actual frame position. See
Slipping a Reference Image.
- Set
the transparency for the reference image in the Transparency field.
NoteYou can also drag the result image to offset
it for a Clone operation by holding down Ctrl+Shift.
