Picture-in-picture that animates itself.

y = a (b + 2x) sin(2π f x) / ( f x (b + x) )

• x is the progress of the move, 0 to 1. Damped Out uses y(x); Damped In uses 1 − y(x).
• a (amplitude) defaults to 1/(2π), because the limit of y at x → 0 is 2πa, so y starts at exactly 1.
• b (damping, default 1): the envelope (b + 2x) / (x (b + x)) decays roughly as 1/x. Smaller b gives a longer, stronger wobble.
• f (cycles, default 1): whole oscillations per move. The phase is zero, so y(1) = 0 for whole f.

Default Rounded Square, Zoom Scale 0.35

Shape Size is a fraction of your timeline's short side, so the picture shape (Circle, Square, Rounded Square, Polygon or Star) is the same size in pixels, with the same margin from the frame edges, on every timeline. The window below is 35% of the short side.

For a card or pill that is wider than tall, choose Rounded Rectangle (or a macro from the Picture Shapes folder) and set Rectangle Height.

1. Close DaVinci Resolve

   Quit Resolve completely so it picks up the new package on the next launch.

2. Double-click the .drfx package

   Double-click 1LineArt_PiP_Collection.drfx. DaVinci Resolve asks you to confirm the installation: click Install. This works on Windows, macOS and Linux.

   Installer or manual install (if double-clicking does nothing, use the installer for your system above, or install by hand): a .drfx is a zip archive. Make a copy, rename it to .zip, extract it and copy the 1LineArt folder from Edit/Effects/ into the folder for your system. Create any missing folders using the exact names shown.

   macOS~/Library/Application Support/Blackmagic Design/DaVinci Resolve/Fusion/Templates/Edit/Effects/

   Windows%APPDATA%\Blackmagic Design\DaVinci Resolve\Support\Fusion\Templates\Edit\Effects\

   Linux~/.local/share/DaVinciResolve/Fusion/Templates/Edit/Effects/

   On Windows you can paste the path straight into the File Explorer address bar.

3. Restart Resolve and find the effect

   Open your project, go to the Edit page, then Effects Library → Toolbox → Effects, then 1LineArt → PiP Transitions. Seven category folders hold the 78 macros (or search "1LineArt").

On the Fusion page: apply the effect from the Edit page, then open the clip on the Fusion page. It appears as a single group node named OneLineArtPiP, with your clip connected to its input and the output going onward.

1. Put your main footage on V1

   The effect draws the PiP on a transparent background, so it needs footage underneath it.

2. Put the PiP clip on V2 or higher

   Trim it to the length you want on screen — the animation starts at its first frame and ends on its last.

3. Drag the effect onto the PiP clip

   From Effects Library → Toolbox → Effects → 1LineArt → PiP Transitions, drop any macro (for example 1LineArt Dynamic PiP) onto the V2 clip.

4. Adjust the five sections

   Open Inspector → Fusion. Choose a Picture Shape, pick a corner with Window Anchor, and click the Border Color and Shadow Color swatches to choose any color.

5. Press play

   Fine-tune timing with Zoom Speed and Border Animation (both in seconds), and the feel with the Easing Curve menus.

Quick tips

• Want a different corner? Change Window Anchor (and Mask Center to crop a different part of the clip).
• Want a calmer look? Lower Shake Motion Scale or untick Enable Transform Shake.
• Want sharp corners? Choose Square, or set Corner Radius to 0 on a Rounded Square.
• Want a star or polygon? Choose Star or Polygon and set Star Points, Star Depth or Polygon Sides.
• Keep the clip longer than the zoom-in and zoom-out times combined.
