Add a stop motion to input.mp4 Frames each pose stays on screen: 5 Output frame rate: 30
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 stop motion 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 |
|---|---|---|
HOLD | 5 | Frames each pose stays on screen. 5 at 30fps is 6 poses a second; higher is choppier. |
FPS | 30 | Output frame rate. |

Give input.mp4 a stop-motion look: keep only every 5th frame (frames 0, 5, 10 and so on) and hold each one for 5 frames, so the picture changes 6 times a second at 30fps. Keep the size, the 30fps frame rate, the 6 second length and the audio unchanged. Use ffmpeg and save it as output.mp4.Run it without Claude
This is the exact command we tested. Save it as stop-motion.sh and run:
sh stop-motion.sh input.mp4 output.mp4Show the command
#!/bin/sh
# Stop motion: keep every 5th frame and hold it for 5 frames, so the picture steps 6 times a second like frame-by-frame animation.
# Usage: sh stop-motion.sh input.mp4 output.mp4 (input at 30fps)
