# Frame timing calculator

Enter a frame count and a rate to see your loop’s total length, how long each frame is held, and how many loops fit common short-form lengths. Fifteen frames is Meleon’s default. It updates live and costs nothing.

*How many loops fit typical short-form lengths*

| Length (typical) | Loops that fit |
| --- | --- |
| 6 seconds | — |
| 15 seconds | — |
| 30 seconds | — |
| 60 seconds | — |

Lengths are typical short-form targets for planning, not platform rules.

## How to use it

1. Set the **frame count** — 15 matches a default Meleon loop.
2. Enter a rate as **fps** or **seconds per frame**; the other follows.
3. Set **loop repeats** for how many times the loop plays through.
4. Read the **total duration** and **per-frame** timing.
5. Use the table to see how many loops fit a target length.

## Questions

**Why does the frame count default to 15?**

A Meleon story loop is built from 15 frames by default, so the calculator starts there. Change the number if you are planning a longer or shorter sequence.

**What is the difference between fps and seconds per frame?**

They are two ways to say the same thing. Frames per second (fps) is how many frames play each second; seconds per frame is how long one frame is held. The calculator keeps both in sync.

**Are the short-form lengths official platform limits?**

No. The 6, 15, 30 and 60-second rows are typical short-form lengths used as a planning guide. They are not rules from any platform, and limits change over time — always check the app you are posting to.

**Does this calculator cost anything?**

No. It runs entirely in your browser and does nothing but arithmetic. Credits are only used when you run a Skill inside your AI chat.
