I searched the data base and found a similar question but it wasn't answered.
I'm running PE 10 on a Mac (O S 10.6.8) with 4GB of RAM and lots of disk space.
First attempt importing a stitched photo (panorama) from LR3 as a .TIF; got this error message - Error: The importer reported a generic error.
Went back to LR and converted to .JPG
Second attempt importing same photo as .JPG format; got this error message - Error: File video dimensions (width/height) too large.
Does anyone know what the limitations are for importing photos into PE 10? I've never had this issue with iMovie.
If you want PRE to be responsive you should follow Steves' recommendation to resize to 1000x750 (SD).
At the technical level I think the maximum allowable dimensions are 4096 x 4096 - but PRE will struggle with pictures that size.
