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.

AV1 / SVT-AV1 Preset Quality & Bitrate Tuner

Project SVT-AV1 output size, bitrate, and approximate VMAF for preset/CRF/resolution, and compare against libaom and libx265

Details

What this tool helps you do

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.

2 examples

1080p24 CRF 30 preset 6 — balanced VOD

A typical VOD encode: 1080p24, SVT-AV1 CRF 30 (balanced quality), preset 6 (good speed/quality). Projects ~1.75 Mbps, ~130 MB for 10 min, VMAF ~90.

4K60 archival — CRF 23 preset 4

High-quality archival encode of 4K60 content at CRF 23 (near-transparent) with the slower preset 4. Projects a large file and high VMAF.
