Mike,
Photoshop would only come into play, to create Alignment Grids for your sheets.
In PS, start with New Image, and from the Image Size, hit the drop-down (probably says "Custom"), and then choose the Video Frame Size to match your Project at the bottom of that drop-down list, say HD 1920 x 1080 with Guides. Set Background to Transparent. Hit OK.
- Your new Image, sized to match the Video Frame Size will Open, and you can see the Guides for the Title-safe and Action-safe areas. You should see a gray/white checkerboard, indicating a Transparent Background.
- In the Layers Palette, chose New Layer at the bottom. Use the Marquee Selection Tool, to draw your first "sheet."
- In the Paths Palette, hit the little fly-out arrow at the top, and choose Make Workpath.
- Then, set the Pencil Tool to maybe 2-3 pixels and Hard, Set the Foreground Color to say red, and go to that same fly-out on the Paths Palette, choose Stroke Workpath, and choose Pencil.
- Now you have a Stroked (only) rectangle on a Layer. Hit Ctrl-T for Free Transform, and with the Cursor just outside the Bounding Box (you might need to expand the view by dragging a corner of that Image to see the Bounding Box clearly), and you will see a little arc with arrowheads. Rotate, as is needed.
- Repeat, with different colors, as is necessary.
- Save_As PSD, and Import that into PrPro. You might find that you do not want all colored rectangles on one PSD, so you can Export each Layer to a separate PSD, to be Imported separately.
Good luck,
Hunt
