Save the JSON above as template.json, then render in the free sandbox:

# Save the JSON above as template.json, then:
curl -X POST https://api.shotstack.io/edit/stage/render \
  -H "x-api-key: $SHOTSTACK_API_KEY" \
  -H "Content-Type: application/json" \
  -d @template.json

# Poll until status is "done", then download response.url
curl https://api.shotstack.io/edit/stage/render/RENDER_ID -H "x-api-key: $SHOTSTACK_API_KEY"
import { readFileSync } from 'node:fs';

const headers = { 'x-api-key': process.env.SHOTSTACK_API_KEY, 'Content-Type': 'application/json' };
const edit = JSON.parse(readFileSync('template.json', 'utf8'));

const { response } = await fetch('https://api.shotstack.io/edit/stage/render', {

Common questions

How do I change the text and media without editing the JSON?

Use the 3 merge fields listed above. Send a merge array with your own values for each field and the API swaps them in at render time, so one template can produce thousands of unique videos.

Can I render this in full HD or 4K for YouTube?

Yes. This template renders 1920×1080 by default. Set output.resolution to "1080" or output.size to a larger 16:9 size in the JSON; the layout scales with it.

Can I use my own photos?

Yes. The template uses 5 images; replace each image asset's src with a public URL of your own file (JPG, PNG or WebP). Keep the timing and effects, or adjust them per clip.

How do I change the text and fonts?

Edit the text on each text asset in the JSON. Fonts come from the timeline fonts list or the asset's font family; add your own font file URL to timeline.fonts to use a brand typeface.
