Error exporting a file

[Rico54]

Hi Staff,

today after a long AP session I've got an error trying exporting a file in TIF format to disk...

System
model: MacBook Pro
model id: MacBookPro17,1
chip: Apple M1
core: 8
ram: 8 GB
sdd: 512gb
macOS: Big Sur 11.4

 

• The MacBook was plugin
• Affinity Photo version 1.9.3 (from Mac App Store)
• Only AP & Finder opened
• Working on Canon RAW from Canon EOS 6D mark II
• Raw files and exported Tif are stored on an external Samsung 1Tbyte T5 formatted with APFS
• Long working session with panoramas & stacking from bracketing, export tiff every image completed then closing the project without saving it
• Creating 6/7 panoramas (from 4 to 7 images each) 
• Creating 5/6  stacks (2 images) only using mask in one of the layer
• Trying to export as tif the last stack then the error occur
• Trying to export on a different volume, same error
• Quitting AP, then repeating the last stack and all works fine.

AP works fast and very well on my MacBook Pro. I believe is a memory problem and I don’t know if there is a solution, maybe I must change my workflow closing AP after 2/3 panoramas or stacks. 

Here the screenshots  of the errors and infos from system monitor.

Best regards. Riccardo.

Hey Rico54,

Did you manage to save it as an .afphoto file before you closed it?

Without knowing the dimensions of the image you were trying to export, it could be struggling to use the swap if your RAM is consumed. I had a panorama last week that was approx 120,000 pixels wide and it was taking 75GB. How much space is free on the HDD?

Hi Chris,

Thanks for your answer.

Normally I don't save to .afphoto when doing panoramas or stacks, exporting in tif 8bit, the panoramas normally under the 12.000 pixels and the stacks at 6240 × 4160 pixels (Canon 6D mkII resolution) the size of the tifs is normally under the 50mb. The internal ssd has 387Gb free (of 512Gb) and the external ssd 318Gb free (of 1Tb). 

I believe is a memory problem. I never got this error with my old iMac i7 27" mid 2010 with 16Gb of ram. I've bought the MacBook Pro 13" M1 because fit perfectly in my camera bag and has good power and battery life but in shop I only find the 8Gb ram version.

I think that's the difference between non-unified and unified memory—there is a loss less latency and it is much more efficient.
