HEIC Issue

I returned from a holiday to Europe to find that some of my images were in the new HEIC format around 900 images. I have the latest Mojave and iPhone 8 iOS systems installed and went about my usual business of importing the images into Photos and then auto deleting them from the phone when complete.

Everything went as planed and the images and few videos look fine when viewed within the Photos app however I typically like to export some of my images from trips and add them to Lightroom so I just export the unaltered originals and then import to Lightroom

The issue I'm having is that the HEIC images when exported are corrupted. The show green pixel boxes either on the lower half or in some cases the side of the exported images.

I decided to try to convert the images to JPG and the result was the same except the pixel corruption shows up a purple instead of green. I have the images as proof and would be happy to send them along with screen shots if you like. I have posted a couple here.

I need to know what the issue is and the fix or that a fix is on the way ASAP.

Thanks

Above is the image in Photos

Above is the exported JPG

Above is a screenshot of the exported HEIC as this forum would not allow the actual .HEIC image to be added to this message.

Clearly there is an issue with HEIC.

iPhone 8, macOS Mojave (10.14), Latest iTunes and iPhone updates.

Here is your, imported into photos then, exported .HEIC on my computer. Bare in mind that I have a iMac with 32GB ram, 4GB graphic card, 1 TB hard drive and a 3.5 GHz intel i7. I thought it might be related to the APFS on hard drive but I have an SSD in my MacBook and I get the same results.

I've just notied this problem, glad that is not unique.

Only 2 photos were problematic, after deleted all from Phone, Computer and iCloud, then restored from Time Machine backup, more photos were affected...nice...

However, I've found out, that if I press Edit on a Mac for these pictures (do nothing else), the photos error disappears.

Hope there will be a fix soon...

For me, the macOS10.14.2 update fixed the problem with HEIC. New HEIC photos downloaded from the iPhone X are fine now, and older HEIc photos, still showing the corruption, can be fixed now by opening them in Edit mode.

Strange as I open the .HEIC images in Photoshop and I get the pixelation all be it grey and somewhat hard to see.

Screen shots.

Oct 12, 2018 2:13 PM in response to Digita1one

Quite strange.

This is what I get:

The middle image is extremely saturated by me on purpose to highlight a possible pixelation. I don't see diagonal pixelated blocks.

Harsh however at least I'm not the only one with the same issue. 😁 Hope Apple sees this and more peps come forward so a fix can be pushed out.

Also added an exported jpeg.

Thanks

Oct 12, 2018 1:44 PM in response to Digita1one

Thanks.

I opened them with Photoshop and both look fine. I don't see any glitch.

The third file (JPG) does have gray pixel blocks.

Oct 12, 2018 1:49 PM in response to Digita1one

I even tried to import your HEIC files in Photos and export them again: no issues at all.

Oct 12, 2018 2:41 PM in response to Digita1one

Let's make an inverse test.

I've just uploaded an HEIC photo I made this summer. You find it in the same shared folder. It's named IMG_0040.HEIC

Do you see any unwanted artifacts?

You'd better look closely at the images as some of my converted images look ok until you zoom in only to find that the pattern is still there just faint.

Opening the Heic Photos in Preview app will not exhibit the problem. Most likely a Metal related rendering issue.

Did you already update to Mojave macOS 10.14.1? Did yesterday's update not fix the problem?
