Make a picture in picture from main.mp4 and inset.mp4 Inset width as a share of the main frame: 0.32 White frame around the inset, in pixels: 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.
Add a picture in picture 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 |
|---|---|---|
SIZE | 0.32 | Inset width as a share of the main frame. |
BORDER | 6 | White frame around the inset, in pixels. 0 removes it. |
MARGIN | 0.04 | Gap from the edges, as a share of the frame width. |

Closest built-in: an overlay on the upper track · desktop and mobile
- Keep your main clip on the main track of the timeline.
- Drag the second clip up into an upper track so it layers on top.
- Resize or position the upper-track clip as needed.
- Press Play to preview; upper-track clips overlap and play together.
Layers a resized clip over the main track, but the page never mentions corner placement or a white frame.
