Regression in v0.29, it has bigger file sizes for avif images (37% worse)

[samuelfernandez]

Are you using the latest version? Is the version currently in use as reported by npm ls sharp the same as the latest version as reported by npm view sharp dist-tags.latest?

Yes, actually caught the regression in my project with a renovate upgrade https://github.com/ng-easy/platform/pull/174

What are the steps to reproduce?

Compress an image to avif format

What is the expected behaviour?

Keep small filesizes

Are you able to provide a minimal, standalone code sample, without other dependencies, that demonstrates this problem?

Let me know if truly needed

Are you able to provide a sample image that helps explain the problem?

Yes, attached size regression avif sharp v0.29.zip

What is the output of running npx envinfo --binaries --system?

v0.29.0 - 17th August 2021
AVIF encoding now defaults to 4:4:4 chroma subsampling. #2562

Try adding .avif({ chromaSubsampling: '4:2:0' }) to use the same behaviour as the previous version.

Perhaps you could also experiment with the quality and speed settings to see what combination works best for your scenario.

That was a fast answer! It fixed the issue both for avif and heif, thanks a lot @lovell!
