What filetype is the most stable for georeferencing in Pro?

Question

ArcGIS Pro 3.4.0

My experience is that georeferencing is buggy in Pro.

What file type is the most stable? TIFF? FGDB? Something else?

Hi @Bud 
For imagery & scans out of a pdf I use a simple open source pdf to jpg converter then clean & clip as needed. Some PDF tools try to be 'smart' and add junk to tiff output. Tiff  is great when Esri/Erdas/etc make it but not something I go to in the same sentence as pdf.

When you convert said tiff to jpg (not sure what Paint does - I prefer IrfanView for basic raster/bmp handling) it may also incorporate some of the 'bad' metadata from the tiff hence issues. The breaking of georeferencing may be due to a resize in the convert process. More reasons exist.

I use png, jpg, jp2000, ecw, and tiff often and usually issues are created at the source and not in Pro; but Pro is less than graceful in handling these mal-formed datasets.... Sounds like an Idea.....

Depending on the size I store a lot of raster data in FGDB. Fantastic placebo performance in my setup and it is a native format that Pro should work with without fault; it's also without weird issues like sneeze deleting the georefence file (not that I don't have easy nearline snapshot backups, but if I don't have to spend 2min restoring a backup....).

Thanks @RichardHowe.

Issues (Pro 3.4.0):

* An image I extracted from a PDF as a .TIFF using Adobe Acrobat only shows up as a white blob in Pro. I solved it by exporting the image to a JPEG in Microsoft Paint, and that worked better in Pro; I could see the image.
* I georeferenced the JPEG and saved the georeferencing. But when I closed the georeferencing, the georeferencing information was lost -- the image was no longer georeferenced. I did the georeferencing again to the same image, saved, closed, and it worked that time.

* With the JPEG, I don't see the Primary Symbology > Classify option mentioned in Easily remove white pixels from georeferenced plan.
* ArcGIS Pro crashed my computer spectacularly when using the georeferenced JPEG in a map. My computer 100% froze, including the mouse not even moving on the screen.
* When I use the JPEG in my map, it only is visible for a short while, then the black pixels disappear after I've moved around in the map a bit. The white envelope/blob still remains. I need to turn the layer off and on again in order to see the black pixels in the image.
* I can't seem to export the georeferenced JPEG to any other format properly, such as TIFF or FGDB. The resulting images are either a white blob or a black blob.

Now that Pro 3.4.2 has been released what issues do people still have that are not yet addressed?

PDFs definitely have some bugs in them. For the most part I have found jpgs to behave themselves though

What issues are you having?
