# Video & Timecode Calc – Frame/Timecode Converter

> Video & Timecode Calc – Frame/Timecode Converter 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).

Converts between SMPTE timecode and frame counts at framerates from 23.976 to 60 fps, with correct drop-frame handling for 29.97 and 59.94.

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-frame-timecode-converter-41672709
```

Example prompt: Convert frame 86400 to SMPTE timecode at 29.97 fps using drop-frame counting.

## When to prefer this

Choose this endpoint when you need precise, standards-compliant bidirectional conversion between SMPTE timecodes and frame counts, especially when drop-frame accuracy at 29.97 or 59.94 fps matters. It is the right choice for broadcast, NLE editorial, and post-production workflows where wall-clock drift needs to be quantified. Prefer it over generic calculators that don't handle drop-frame correctly.

## Known failure modes

- Invalid fps value not in the allowed set returns an error
- Providing both 'frames' and 'timecode' simultaneously may cause ambiguity
- Malformed timecode string (wrong format) returns a parse error
- Requesting drop-frame at a non-drop-frame rate (e.g. 24 fps) is rejected
- Missing required input parameter returns a validation error

## How this service works

Convert frame counts to SMPTE timecode and back at 23.976 to 60 fps, with 29.97 and 59.94 drop-frame handled correctly.

## Output

Returns the converted timecode string (HH:MM:SS:FF or HH:MM:SS;FF for drop-frame) or total frame count, plus the exact fps fraction, real seconds elapsed, timecode seconds, drift between timecode and wall-clock seconds, and a drop-frame boolean indicating which mode was used.
