maximum import file size for stills?

You could downsize and/or crop to relevant project pixel size in Photoshop. Don't understand "...to zoom into the image .....

I believe 4012 x 4012 is the max for Premiere, but even then issues have been reported. Less than 2000 seems to be a magic number for workability.

Please excuse my ignorance, but what would be the benefit of importing stills 4000 pixels wide if the project is say 1920 wide? In my world it would be better to do the cropping in photoshop and - if needed - add pixels there.

i 2000 pixels doesn't do me much good in a 2k video!
What does this mean, please?

Because you can pan and zoom on the image without losing resolution if the image is much larger to begin with.

Interesting - I've been a stills photographer for 40 years and am only two years into video - thank you for the explanations. I'll certainly "contact mr. Burns.

Studio3D,

I do a fair amount of work with stills in Premiere. I always plan the size necessary for the pans and re-size to exactly what is required, based on the Project's image dimensions. As I do not do any "random pans and zooms," (each is choreographed tightly) I do all of the re-sizing work in PS, before Import. However, with your hi-rez Project, you might well be pushing the limiting size in Premiere. You may have to step back, just a little, and tighten your pans to accommodate these limits.

Good luck,

Hunt

PS I like the re-sizing algorithms in PS better than any I have worked with in PrP. Have not experimented with CS4, so I might change my tune, should they have changed their algorithms.
