Image rotation kind of slow

Help & Support
1

HI folks,

when moving image files from sd-card to harddrive (exif-rotating at the same time) I always found it to be quite slow.
I upgraded my camera and with bigger image files this is getting worse now of course.

It seems image conversion is single threaded and that might be the reason why it feels rather slow?
Maybe there is some way to use all the cores in my machine while moving/rotating images? Running it async. maybe?

The actual command I use is following (it reduces jpg quality to 85 as well, but after some tests, that does not slow down things heavily):
Image CONVERT=jpg PRESERVEDATE ROTATE=EXIF REPLACE=always QUALITY 85 NOLOSSLESS NOREDUCE

Thanks for reading.. o)
Rob.

There's currently no way to speed up the internal image rotation command (at least if you also want to re-compress the JPEG data at the same time).

If you need faster, a dedicated image processing tool/command may be worth looking at. You should be able to automate a good one via Opus buttons/hotkeys to keep it integrated in the workflow you already have.

Ok, then what if I just exif-rotate and drop the recompression ?!
I ask, because you said "at least if you also want to re-compress.." o)

I'd expect that to be quite fast, as long as the images are such that they can be rotated losslessly.
