Add a tiled repeat to input.mp4 Second the 2x2 grid appears: 1.0 Second the 3x3 grid replaces it and holds to the end: 2.0
Several videos, several effects, one ask
Put your clips in the folder, mention them with @, and ask for everything at once. Claude runs one tested script after another on each clip, then joins them.
Add a tiled repeat to @clip1.mp4, put a sale badge on @clip2.mp4, give @clip3.mp4 a VHS look, then join all three with crossfades.
Settings you can change
Ask Claude to change any of these, or edit them at the top of the command.
| Setting | Default | What it does |
|---|---|---|
TWO_AT | 1.0 | Second the 2x2 grid appears. |
THREE_AT | 2.0 | Second the 3x3 grid replaces it and holds to the end. |

In input.mp4, repeat the video across the screen in a grid. From 0 to 1 second show it full frame. From 1 second, show a 2x2 grid: four copies of the same video, each scaled to half the width and half the height (the whole frame shrunk, not cropped), with no gaps. From 2 seconds to the end, show a 3x3 grid: nine copies, each the whole frame scaled to a third of the width and height, with no gaps. All copies play in sync. Keep the size, frame rate (30fps), length and audio the same. Use ffmpeg and save it as output.mp4.Run it without Claude
This is the exact command we tested. Save it as tiled-repeat.sh and run:
sh tiled-repeat.sh input.mp4 output.mp4Show the command
#!/bin/sh
# Tiled repeat: the full shot splits into a 2x2 grid of itself at 1s, then a 3x3 grid at 2s.
