## Overview

A planning tool for AV1 encoding — model the tradeoff curves BEFORE you encode. Anchored on published benchmarks (NETINT, SPIE, Streaming Learning Center, SVT-AV1 docs). Real output is highly content-dependent; treat all numbers as order-of-magnitude estimates.

## Inputs

- **Resolution** (select)
- **Framerate (fps)** (number)
- **CRF / QP (1-63)** (number)
- **SVT-AV1 Preset (0-13)** (number)
- **Clip Duration (seconds)** (number)
- **Compare codecs (SVT-AV1 vs libaom vs x265)** (checkbox)

## When to use

- Estimate the bitrate and file size of an SVT-AV1 encode before starting a long encode.
- Compare quality and compression tradeoffs for different CRF, preset, resolution, and framerate settings.
- Evaluate an AV1 configuration against approximate libaom and libx265 results.

## How it works

- Select the target resolution and enter the clip framerate and duration.
- Set the CRF/QP value and SVT-AV1 preset within their supported ranges.
- The tuner projects approximate bitrate, file size, and VMAF for the selected configuration.
- Enable codec comparison to view the projected SVT-AV1 result alongside libaom and libx265.

## Use cases

- Plan storage requirements for video-on-demand libraries before encoding.
- Choose a practical quality and speed balance for 1080p or 4K delivery.
- Compare codec projections when evaluating an AV1 migration or encoding workflow.

## Frequently asked questions

### What does this tool estimate?

It estimates SVT-AV1 bitrate, output size, and approximate VMAF for the selected settings.

### Which inputs affect the projection?

Resolution, framerate, CRF/QP, preset, and clip duration affect the projection.

### What does a lower CRF value generally indicate?

A lower CRF value generally targets higher quality and may produce a larger file.

### Can I compare AV1 with other codecs?

Yes. Enable codec comparison to compare SVT-AV1 with libaom and libx265.

### Are the results exact encoding measurements?

No. They are order-of-magnitude estimates because actual results vary with video content.
