How to convert JPG to 10bit AVIF?

[LITUATUI]

I usually use Gimp to convert my JPG images to 10bit AVIF, but ImageMagick is much better for batch conversions.

Is it even possible to do it with ImageMagick?

Thanks!

As far as I know, IM can only create 8 bit/channel AVIF, not 10 bit/channel.

That's what I thought, it's a shame as 10-bit encoding is more efficient.

Have you tried using -depth 10?

Have you tried using -depth 10?

Yes, I did.

magick mogrify -format avif -depth 10 *.jpg

It produces 8-bit AVIF images.

We don't write 10-bit AVIF images just yet-- although ImageMagick can support 10-bit. Its just a matter of taking the time to accommodate 10-bit. Currently we do not have an ETA on when this capability will be exported.

Thanks. I'll read every changelog from now on... 👀

Nowadays AVIF and 10-bit is the best combination for website images by far.

Thanks for the problem report. We can reproduce it and will have a patch to fix it in the GIT main branch @ https://github.com/ImageMagick/ImageMagick later today. The patch will be available in the beta releases of ImageMagick @ https://imagemagick.org/download/beta/ by sometime tomorrow.

Look for the ImageMagick 7.1.0-28 release within a few days. It supports reading and writing 10 & 12-bit AVIF images.

That's awesome. Thanks!

The update already arrived to Arch distros. I'm using EndeavourOS and it works. I now get 10-bit AVIF files, thanks!

magick mogrify -format avif -depth 10 *.jpg

Running the magick identify command:
AVIF 900x583 900x583+0+0 10-bit sRGB 52156B 0.000u 0:00.000
