Reprojecting raster taking hours, not sure if it's even working

Question

Hello,

I'm trying to reproject a couple single band landsat images to use in my analysis. I've had the first reprojection running for almost 2 hours and it's at 0% progress. I reprojected a DEM covering the same extent and it took 10-15 minutes. Is there any way to see if it's even working? No error messages, but no progress either. I have parallel processing factor at 100%. Any help would be appreciated.

@DanPatterson I'm having this issue today, and I have in the past with no real understanding why. Raster is 573MB uncompressed, 1cm resolution ortho I produced in Drone2Map. Reprojecting with the same output cell size as the input raster, and parallel processing factor using all 16 of my cores (7950X3D). Thing just sits at 0 and doesn't move. Been that way for 2 hours now. CPU, GPU, and RAM consumption are no different from idle. I'm thinking its hung up on something but I'm not sure why. I'm just gonna do it in python instead. This is one of those instances where I wish the progress bar was a bit more informative, or that we had a console similar to Drone2Map where we could see what process is actually running/hung up.

Oh, and Pro version 3.6 (up to date).

Any advice would be much appreciated!!!

I figured out the problem: It was cell size. I was defining the cell size by using the input raster and it was using degrees, so the cell size was extremely small. I thought it would convert those dimensions to meters, but as soon as I selected Preserve Resolution, it changed them to meters and the projection took no time at all.

filenames and paths with space aren't great, and are you projecting from utm to geographic? or the reverse
