Very slow thumbnails when using Sony HIF files
« on: October 16, 2023, 05:41:44 AM »
I recently made some photos using the Sony HIF format.  The previews were extremely slow to load.  There were only about 400 images in the folder, but it took 10-20 minutes to load all the thumbnails.  Is this just because of the HIF files, or is there some kind of setting that I should change.  If it is the file format is there any plan to make them load faster in the future?

Mac M1 Max, 32 gigs RAM, Sonoma, Photo Mechanic Plus Version 6.0, build 6880 (6fb7605)

While HIF files certainly load slower for me than something like a JPEG, 10-20 minutes to load the content of a folder sounds like there are other things going on.

For a problem like this, I suggest contacting our support folks at:

By email:

By phone: +1 503.547.2888

Hours: Mon-Fri, 9:00am-5:00pm [PST/PDT]

I'd probably recommend calling, for this issue, but if you'd like to troubleshoot by email, please send us your log file, which you can find by going to Help -> Reveal Support Data and clicking 'Yes' in the window that appears.
