Built By APIs, Seen By Millions

PixelRender generates crisp, 60fps MP4s matching your exact layout demands.

How It Works

A simple three-step pipeline from data to MP4.

1

Send JSON

POST a declarative JSON recipe describing scenes, assets, audio, and visual transitions.

2

API Renders

Our serverless FFmpeg workers download assets, compile the timeline, and render the MP4.

3

Receive MP4

Get a webhook callback or poll the API to download your finished production-ready video.

Frequently asked questions

How do credits work exactly?
A baseline credit represents 30 seconds of rendering time at 720p resolution. Renders are rounded up to the nearest 30 seconds. Higher resolutions apply a flat multiplier (2x for 1080p, 4x for 4K).
Do credits roll over?
Monthly subscription credits do not roll over. However, purchased Credit Packs never expire and roll over indefinitely across active plans.
What happens when I run out of credits?
Your renders will seamlessly continue using your plan's standard overage rate (e.g. $0.12/credit on Pro). To save money, you can purchase credit packs at any time.
Is there a free tier?
Yes! We offer a non-renewable free tier with 20 credits (10 minutes of rendering) so you can fully evaluate the platform before choosing a paid plan.
