Extract GIF from video

“Chatter” (a team messaging app like Slack) lets users turn video moments into reaction GIFs.

API

ittybit animation \
  -i https://chatter-app.com/clips/funny-moment.mp4 \
  --format gif \
  --start 3 \
  --end 6 \
  --width 320

const job = {
  input: 'https://chatter-app.com/clips/funny-moment.mp4',
  kind: 'animation',
  options: {
    format: 'gif',
    start: 3,
    end: 6,
    width: 320,
  },
};

const res = await fetch('https://api.ittybit.com/jobs', {
  method: 'POST',
  headers: {
    Authorization: `Bearer ${process.env.ITTYBIT_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify(job),
});
const data = await res.json();

import requests

job = {
    "input": "https://chatter-app.com/clips/funny-moment.mp4",
    "kind": "animation",
    "options": {
        "format": "gif",
        "start": 3,
        "end": 6,
        "width": 320,
    },
}

res = requests.post(
    "https://api.ittybit.com/jobs",
    headers={"Authorization": f"Bearer {api_key}"},
    json=job,
)
data = res.json()

JOB='{
  "input": "https://chatter-app.com/clips/funny-moment.mp4",
  "kind": "animation",
  "options": {
    "format": "gif",
    "start": 3,
    "end": 6,
    "width": 320
  }
}'

curl -X POST https://api.ittybit.com/jobs \
  -H "Authorization: Bearer $ITTYBIT_API_KEY" \
  -H "Content-Type: application/json" \
  -d "$JOB"

This extracts a 3-second animated GIF starting at 3 seconds. Keep segments short and dimensions small — GIFs get large fast.

CLI

ittybit animation \
  -i funny-moment.mp4 \
  -o reaction.gif \
  --start 3 \
  --end 6 \
  --width 320

Small and sharp

GIF files are uncompressed per frame. Keep them small:

ittybit animation \
  -i clip.mp4 \
  -o reaction.gif \
  --start 5 \
  --end 8 \
  --width 240 \
  --fps 8

Consider WebP instead

WebP supports animation and produces much smaller files than GIF:

ittybit animation \
  -i clip.mp4 \
  -o clip.webp \
  --start 5 \
  --end 10 \
  --width 320

If your platform supports WebP (most modern apps do), prefer it over GIF.
