Made by the script on this page, from our own test clip. ## Get this effect 1. ### Switch to Code in your [Claude Desktop App](https://claude.com/download) 2. ### Install the skill (once) ``` Install the Recharm video effects skill: download https://recharm-growth-staging.s3.us-east-2.amazonaws.com/website/downloads/recharm-video-effects.zip and unzip it into ~/.claude/skills ``` 3. ### Ask for the effect ``` Add a teal and orange to input.mp4 How hard the tint is pushed: 0.55 The color cool areas lean toward: (40, 160, 170) ``` ## 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 teal and orange 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 script. | Setting | Default | What it does | | -------------- | ---------------- | ----------------------------------------------------------------------------------------------- | | `STRENGTH` | `0.55` | How hard the tint is pushed. 0 leaves the clip alone, 1 is a heavy grade. | | `TEAL` | `(40, 160, 170)` | The color cool areas lean toward. | | `ORANGE` | `(255, 150, 60)` | The color warm areas lean toward. | | `SOFTNESS` | `8` | How gently a pixel moves from teal to orange as red overtakes blue. Lower gives a harder split. | | `SHADOW_LEVEL` | `80` | Pixels darker than this lean teal whatever their color. | | `DESATURATE` | `0.4` | Share of each pixel's own color dropped so the two tints read cleanly. | ## Without the skill Don’t want to install the skill? Paste this prompt into Claude Code and Claude writes the script itself. ``` Give all of input.mp4 a teal and orange grade, on every frame from start to end. For each pixel (RGB, 0-255): take its brightness Y = 0.299R + 0.587G + 0.114B; work out how warm it is as w = 1 / (1 + e^(-(R - B) / 8)), then multiply w by min(Y / 80, 1) so dark pixels count as cool; build a tint by blending from the teal offset (40, 160, 170) minus its own brightness to the orange offset (255, 150, 60) minus its own brightness by w (brightness with the same 0.299/0.587/0.114 weights); then the new pixel is Y + 0.6 x (pixel - Y) + 0.55 x tint, clipped to 0-255. Warm areas like the cream label should end up peachy orange, around RGB (225, 180, 135), and cool areas like the pale backdrop around RGB (150, 215, 225); the purple bottle turns a slate teal-blue. Do it in Python with numpy, piping raw frames from and back to ffmpeg. Keep the size, 30fps frame rate, length and audio the same, encode H.264 yuv420p and save it as output.mp4. ``` ## Run it without Claude This is the exact script we tested. Save it as `teal-and-orange.py` and run: ``` python3 teal-and-orange.py input.mp4 output.mp4 ``` ``` """Teal and orange: warm colors (skin, labels, wood) pushed toward orange, everything cool and dark toward teal. Usage: python3 teal-and-orange.py input.mp4 output.mp4 Needs Python 3 with numpy, and ffmpeg.
