Flayr FX Multiscreen

About Flayr FX Multiscreen

Video walls, split screens, reaction grids, social mosaics. Flayr FX Multiscreen lays your clips out in a grid for you, in Premiere Pro or After Effects: pick 4, 9 or 16 cells, load your clips and press Build grid. Every clip is scaled, positioned and cropped to its cell, with gaps and margins to the pixel.

What it does

• Grids and strips: 2×2, 3×3 and 4×4, plus 4×1, 1×4, 8×2 and 2×8 strips. Auto picks the layout whose cells best match your footage. Fill the cells by rows or by columns.
• From the project or the timeline: select clips in the Project panel and it builds a new sequence or comp, or select clips already in your sequence (or layers in your comp) and it arranges them into the grid where they are.
• A live preview: drag cells to swap them, empty one with ×, sort A–Z or shuffle, and repeat your clips to fill any empty cells.
• Fill or fit: fill each cell and crop the overflow, or fit the whole clip inside with letterboxing. Gutter and margin in pixels.
• Any canvas: HD, UHD, vertical 1080×1920, square, 4:5 or a custom size.
• Nested for you: the finished grid drops into the sequence or comp you have open, at the playhead, as one nested sequence or pre-comp on a free track, so nothing in your edit is overwritten. Clips arranged on the timeline are nested or pre-composed in place. If the sizes differ, it’s scaled to fit.
• In Premiere Pro: one video track per cell with Motion and Crop set for you, audio from cell 1 only, all or none, and an option to trim every clip to the shortest.
• In After Effects: one layer per cell, cropped with a mask that’s replaced (not stacked) when you rebuild, rounded corners, a duration from the longest or shortest clip or a fixed length, your frame rate and an optional background solid. All one undo.
• Remembers your settings for next time.

Who it’s for

Editors and motion designers who build split screens by hand: social and YouTube editors, event and music videos, sport and corporate montages, and anyone making a video wall for a screen or a pitch.
