Join clipA.mp4 and clipB.mp4 with a wipe transition Length of the transition in seconds: 0.6
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.
Put a sale badge on @clip1.mp4, give @clip2.mp4 a VHS look, then join them with a wipe transition.
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 |
|---|---|---|
D | 0.6 | Length of the transition in seconds. |

Join clipA.mp4 and clipB.mp4 with a 0.6 second wipe transition: a straight vertical edge moves from the right side to the left side, revealing B behind it (ffmpeg xfade wipeleft). Crossfade the audio over the same 0.6 seconds. Match B's size and frame rate to A. Use ffmpeg and save it as output.mp4.Run it without Claude
This is the exact command we tested. Save it as wipe-transition.sh and run:
sh wipe-transition.sh clipA.mp4 clipB.mp4 output.mp4Show the command
#!/bin/sh
# Wipe transition: a hard vertical edge sweeps right to left, swapping clip A for clip B, over 0.6s. The sound crossfades underneath.
# Usage: sh wipe-transition.sh clipA.mp4 clipB.mp4 output.mp4 (both clips need an audio track)
