# Accepted frames

> Understand what makes a pose frame 'accepted' and how it affects your billing.

# Accepted frames

Kynasmith bills on **accepted frames** — the pose frames that are successfully received and processed during a detection session. This page explains how billing works and how you can predict costs.

## What is an accepted frame?

An accepted frame is a pose frame that Kynasmith successfully receives and processes during a detection session. Each accepted frame counts toward your monthly quota.

Frames are not billed if the session has already ended, if the frame is a duplicate, or if it was dropped due to connection issues.

## Do low-confidence frames count?

**Yes.** Frames with low landmark confidence are still processed and billed. Low-quality detections are valid signals for movement detection.

If no pose is detected in a video frame, no pose frame is sent to Kynasmith, so nothing is billed for that video frame.

## How to predict billing

You can estimate billing impact before submitting frames:

1. **Check `accepted_frames_total` on completed sessions** — The session result includes the total count of accepted frames, which matches what was billed.
2. **Use short sample videos in `replay` mode** during development to calibrate frame counts before running on full-length content.
3. **Use the usage API** to check cumulative usage across sessions:
   * `GET /api/usage` — Organization-level totals
   * `GET /api/usage/projects/{project_id}` — Project-level breakdown

## Reducing frame consumption

* **Lower your frame rate** — If your use case does not require 30fps analysis, configure your SDK or integration to send frames at a lower rate.
* **Use `replay` mode with trimmed videos** during development and testing.
* **Finalize sessions promptly** when you have all the data you need, so no additional frames are processed.
* **Cancel sessions** that are no longer needed rather than letting them idle.

## Billing cycle

Accepted frame counts reset at the start of each billing cycle (typically monthly). If you exceed your quota during a cycle, subsequent session creation may be blocked until the next cycle begins or you upgrade your plan. See [Billing & limits](/billing/overview) for details.
