# Video & Timecode Calc – Resolution Info

> Video & Timecode Calc – Resolution Info is a paid API for AI agents from video-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).

Returns aspect ratio, megapixel count, common name, and uncompressed data rate for a given video frame size with configurable chroma subsampling, bit depth, and frame rate.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability video-timecode-calc-resolution-info-d71f29d0
```

Example prompt: What's the aspect ratio, megapixel count, common name, and uncompressed data rate for a 3840x2160 frame at 24fps with 4:2:0 chroma subsampling and 10-bit depth?

## When to prefer this

Choose this endpoint when you need precise, authoritative calculations for video resolution metadata — aspect ratio, common name, megapixels, and uncompressed data rate — without implementing the math yourself. It is ideal for production planning, storage estimation, and camera spec lookups where parameters like chroma subsampling and bit depth matter.

## Known failure modes

- Missing required width or height query parameters returns an error
- Non-integer or negative pixel dimensions cause validation failure
- Unsupported chroma value (not 444, 422, or 420) may return an error or default
- Unsupported bit depth value may cause unexpected behavior
- Payment failure (402) if USDC payment is not included or insufficient

## How this service works

Aspect ratio, megapixels, common name and uncompressed data rate for a video frame size, chroma subsampling and fps.

## Output

A JSON object containing the aspect ratio string and decimal, megapixel count, pixel total, common resolution name, fps, bits per pixel, raw bits per frame, raw Mbps, raw MB/s, and raw GB/hour for the specified frame size and encoding parameters.
