sid to geoTiff tiles

I have two sid files, around 25GB, that I need to process. I need in the end geoTiff tiles (1GB in size would be fine) of a sub area defined by a polygon. And I need to preserve the data quality.


I have tried extract by mask, thinking that I could cut the sid down with the polygon to make the file size smaller, but it did not make an output after an hour of running even with a relatively small polygon mask.


Next I looked at LizardTech's tools here:


I ran the command "mrsidgeodecode -wf -i input.sid -o output.tiff" on a 1GB sid, I downloaded for testing, and it failed.


What is the best way to do this?
