Add a mirror flip to input.mp4 Flip: hflip
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 mirror flip 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 |
|---|---|---|
FLIP | hflip | hflip mirrors left to right; vflip turns the picture upside down instead. |

Mirror input.mp4 left to right for its whole length, like a front-camera selfie: column x of every frame moves to column (width - 1 - x), with nothing flipped upside down, cropped, scaled or recolored. Keep the size (540x960), 30fps and the full 6 seconds, and keep the audio as it is (don't reverse or change it). There's no text to draw, but if you add any, draw it with Pillow, not ffmpeg's drawtext. Use ffmpeg, encode H.264 yuv420p and save it as output.mp4.Run it without Claude
This is the exact command we tested. Save it as mirror-flip.sh and run:
sh mirror-flip.sh input.mp4 output.mp4Show the command
#!/bin/sh
# Mirror flip: the whole picture turns left to right, like a front-camera selfie; the sound stays as it is.
# Usage: sh mirror-flip.sh input.mp4 output.mp4
set -e
IN="$1"; OUT="$2"
FLIP=hflip # hflip mirrors left to right; vflip turns it upside down
ffmpeg -y -i "$IN" -vf "$FLIP,fps=30" -c:v libx264 -crf 18 -pix_fmt yuv420p -c:a copy "$OUT"
