Gaps and frames
One gap for every seam or a different width per seam. Add a coloured frame, glow, shadow and name tags.
A JugglEdit panel for Adobe Premiere Pro
Split screens,
built on your timeline.
Select your clips, pick a layout, drag the borders. Multiplex writes the Motion, Crop and keyframes for you, and every cell stays a real clip you can keep editing.

How it works
-
01
Select your clips
Stack your clips on the timeline and select them. Multiplex reads them straight from the sequence.
-
02
Pick a pattern
Grids, stacks, a big cell with a column, or a shape cut. The preview shows the layout first.
-
03
Drag and style
Pull borders, set gaps, round or slant the cells. Premiere follows, and History steps you back.
Try it
Drag the borders.
A small copy of the Multiplex preview. Grab a round handle to move a border, or a ring where borders meet to move both at once.
Animate
Round corners show on straight seams here. In Premiere, Multiplex handles slanted, rounded and curved cells together.
Features
Everything a split screen needs,
in one panel.
Slant and curves
Tip borders into diagonals, bend them into curves, or draw a freeform outline.
Rounded cells
Round every corner, or each one on its own. The crop follows the picture.
Perspective and 3D
Turn the layout into a prism or a carousel, tilt cells, add reflection and shading.
Face framing
Frame faces finds the people in each shot and centres them in their cell, with safe zones to check against.
Snap and balance
Borders snap to common ratios. Smart balance tidies a hand-dragged layout in one click.
Shapes and spotlight
Cut the frame into shapes, or spotlight one cell over a blurred, dimmed backdrop.
Layout library
Save a layout with its styling. It lives in the sequence and reopens with the project.
Real keyframes
Everything lands as normal Premiere keyframes, timed right on speed-changed and reversed clips too.
Every format from one layout
Make 16:9, 9:16, 1:1 and 4:5 versions as new sequences in one click, each at its own frame size. Re-arrange to fit turns the splits so cells keep their shape, or Keep the pattern holds the layout as it is. Every clip stays in its cell. Link the versions, and when you change a still layout, every version follows.
Unlimited clips
There's no clip limit. Select as many clips as you need, and Multiplex lays them all out.
Nest, and keep control
Nest the layout into a single clip for a cleaner timeline. Select the nest in your main sequence and Multiplex still edits the cells inside it, with no need to open the nested sequence.
Animation
Bring the layout in. Morph to the next one.
Pick a pattern and Multiplex keys every cell for you: in, hold, out. Move from one layout to a completely different one and the cells travel between them.

Does it work on Windows?
Yes, Multiplex runs on Windows and Mac. The face tools (Frame faces, Keep faces clear, Pop out, Portals) are Mac-only. On Windows, Follow the speaker and Match colours need ffmpeg installed.
Which Macs?
Macs with Apple silicon (M1 or later).
Which Premiere Pro versions?
Adobe Premiere Pro [versions].
How much is it?
$29 while the launch price lasts, then $45.
Can I try it first?
Yes. Multiplex is free for 14 days.
Do I need other plugins?
No. Multiplex uses Premiere's own effects. Rounded corners use Film Impact's Rounded Crop, which comes with Premiere Pro 25.5 and later.
Do my projects need Multiplex to open?
No. Multiplex leaves normal clips, effects and keyframes, so the edit opens on any Premiere, even without Multiplex installed.
How do I get it?
After checkout, Lemon Squeezy emails you the download link and your receipt.
