I'm trying to convert a very large jpg file to a tiled exr to make it more efficient. I have a memory allocation error when trying to convert using the exr tool. Is there a reason for this ? I have 32gb of memory. I tile size was set to 64 which seems very small to me. Should I be setting this higher (to 1024 or something) ?

It only seems to create an error when writing to file. Could this be a security issue ?
Update: not a security issue. I managed to convert a different, smaller JPG.Last edited by stevesideas; 09-01-2017, 09:39 AM. -

What is the resolution of this .jpg file? We can perform a test if you upload it somewhere and send a link to our support mail.Originally posted by stevesideas View PostComment

Hi again,Originally posted by stevesideas View Post
No need to share the file. I'm getting the same issue here with jpg file and res. 50000x50000 on 32gb machine. Now will check on 64 gb machine and let you know the result.
Resizing the image to 40000x seems to work fine on 32gb.Comment

okay. Good to know you are getting the same issue. Hopefully there is a way around this. The tiled exr files do seem to come out very large in file size.Comment

This is actually a memory issue. To be able to handle such big resolution, large amount of free continuous memory is required. We can try to change the code for the EXR conversion to decrease the memory consumption for 8bit image format. Keeping the high dynamic-range for this conversions is not needed.
Can you resize this image to a smaller res. (40 000px) to complete the project?Comment
