Loading of Light frames takes 2 hours

I am loading the light frames from an external drive. They are DNGs converted to Tiff in full resolution (42MP resulting in 256MB for each Tiff file). I have around 700 light frames. Is there any way to speed up the process or to save the loaded file list once it has loaded into A.P.P. ? I had a heap size crash once I started to analyze stars with a master flat and dark so I upped the allocated Ram to 8GB. Right now I am again loading the light frames. Thanks in Advance and best regards,

Hi Ben @benolry,

Yes I understand the issue, initial loading of the frames to be used consists of just reading the frame's metadata, so that should be really fast. For TIFF frames however, the whole frame is read currently, which causes the long loading time.

(700 frames is a lot though... but that aside)

I will write this down to have this work much faster 😉
