Make Perspective Pinning Faster
If you’ve ever had to replace a screen, or even if you’ve had to place artwork on a billboard within After Effects, you know how often you have to perform the same steps to position four perspective pins to the edges of a composition prior to beginning to work on the area of interest.
MaskPin eliminates the need for this step altogether. When you apply the MaskPin plugin to a mask in your composition, the software automatically places all four perspective pins in your composition with a single click. This alone saves you time and effort when you have to perform this action on every composition in which you want to use perspective.
What Is MaskPin?
Perspective pinning is commonly used to place graphics onto objects that appear at an angle, such as laptop screens, phone displays, posters, signs, or billboards. Normally, artists use the Corner Pin effect and manually position each corner until it matches the desired area.
MaskPin is a lightweight native After Effects effect that changes this workflow. Rather than positioning pins from the composition boundaries, it generates them directly around your masked region.
This approach makes screen replacements significantly faster because the starting position already matches the object you’re editing. Whether you’re creating UI mockups, replacing advertisements, or compositing motion graphics onto perspective surfaces, the plugin minimizes the amount of manual work required before editing even begins.
Why MaskPin Makes Your Workflow Easier
Instead of introducing complicated tracking systems or additional panels, MaskPin focuses on solving one specific task extremely well: fitting perspective pins directly to a mask.
Features
One-Click Mask Fitting
Simply draw a mask, apply MaskPin, and press Fit Pins To Mask. The plugin instantly positions all four perspective pins around the masked area, eliminating manual corner placement.
Direct Support for 4-Point Masks
If your mask already contains four vertices, MaskPin can use those exact points as perspective corners. This is especially useful when working with screens, posters, signs, and other rectangular objects viewed from an angle.
Interactive Composition Viewer Handles
Instead of adjusting values numerically, you can drag the custom pin handles directly inside the After Effects Composition Viewer, making visual refinement much faster and more intuitive.
Native After Effects Effect
MaskPin works as a native effect without requiring CEP panels, external scripts, or precomposition workarounds. Everything runs directly inside the After Effects effects pipeline for a cleaner workflow.
Optimized Performance
The plugin supports SmartFX rendering, Multi-Frame Rendering, and full 8-bit, 16-bit, and 32-bit color processing, making it suitable for both lightweight and professional compositing projects.
Ideal for Everyday Motion Design
MaskPin is particularly useful for:
- Screen replacements
- Phone and tablet UI mockups
- Laptop display compositing
- Billboard replacements
- Poster and sign mockups
- Perspective graphic placement
- Motion design presentations
- UI walkthrough videos
- Fast masked-region perspective setup
Rather than replacing advanced tracking software, it speeds up the initial setup stage that nearly every compositing project requires.
Tips for Better Results
For the best experience, create clean masks that closely match the object you intend to replace. Accurate masks produce more precise pin placement and require fewer manual adjustments afterward.
When working with rectangular objects like monitors, smartphones, or posters, using a four-point mask allows MaskPin to align the perspective almost instantly.
If your project involves camera movement or object tracking, use MaskPin to establish the initial perspective, then combine it with your preferred tracking workflow for even better efficiency.
Finally, use the Composition Viewer handles for quick visual corrections instead of relying solely on numerical parameter adjustments. This keeps your workflow fast and intuitive.
Final Thoughts
While perspective pinning is just one aspect of the compositing process within After Effects, it can become a time-consuming process when performed over and over again on different projects. MaskPin automates the placement of perspective pins around any masked areas within your composition.
MaskPin’s native implementation in After Effects, combined with the automation of the placement of perspective pins, makes this a vital tool for motion graphic designers, compositors, and anyone who works with screen and rectangular object replacements in After Effects. MaskPin was created to make your workflow easier by eliminating unnecessary steps in the composition process.
