AVIF format

[TMPhoto]

Hi Im looking at exporting AVIF files from LR and opening them in Photoshop and am impressed at the reduced size without lack of quality. A 1920 pixel landscape image with 90% compression is approx 350K rather than 700K JPEG which would make sense for files using on websites etc... 

Using Mac, however when i open AVIF file with Photoshop it opens in ACR and adds a XMP sidecar to the file. I can then open from ACR into PS but cannot save file. If i choose to close file without saving, any changes made in ACR seem to be preserved in xmp. 

it would be good to be able to make changes to AVIF file within PS ie crops and adjustments and resave as AVIF - but not sure if this is possible? I guess at the moment -  if i want to use AVIF files for website - best to make all changes first and then export as AVIF from Lightroom. 

I am considering using  AVIF files for photography website project as may be a better choice than JPEGS for maintaining high quality at smaller size,  but would like to be able to open and edit files within photoshop once exported from LR.

Any advice appreciated - also is there a way to write xmp sidecar into file - like with DNG files?.

Hey, @TMPhoto. Thanks for the detailed post. 

Instead of opening the file directly in Photoshop, you can use Lightroom to make adjustments, crop, and then integrate Photoshop as a step in your workflow and use 'Edit in Photoshop.' Head here to learn more about Edit in: https://adobe.ly/40cvoj2

The finalized version from Photoshop will come back to Lightroom & you can export it as AVIF from there. This way, you'll skip managing an XMP sidecar generated by Camera Raw. 

Let me know if this helps. Thanks!

Thanks Sameer, yes if i do choose to proceed with AVIF rather than JPEGs ( to me they actually look slightly sharper at half the size of JPG), then yes that approach would be good and save having to import file again into LR! Is there a way for xmp file being contained within AVIF files such as with DNG files i wonder!?
