best still resolution for video?

Interesting, we’ll have to see what’s causing the difference here.

well if the image is 720×480 pixels it is being measured in Pixels and therefor cannot be at any rez other that.

The problem lies within the way that photoshop allows you to create a file. You can create a new file in
either version of the CS version of Photoshop, select the default for 720×480 and then type in a rez of 400 dpi and photoshop resizes the image to 1.8″ x1.2″ instead of the 10″ x 6.67″ size when you are at 72 dpi.

If you create a new Default 720×480 @ 72 doc in photoshop- then change the DPI to 400– the physical image size stays the same ( at 10 x6.67 inches) even though the resolution and pixel size increase. (and the file jumps from 1.1 megs to over 30mgs)

Sorry, didn’t mean to be so dogmatic with the wrong comment. My experience has been DV and SD. I know you do a lot of HD so perhaps somethere is awry in FCP that imports it differently with an hd still. But there’s no magic. It’s still just a set number of pixels at any DPI. Kind of a physical impossibility to create a better image just because it’s tagged with a different dpi.

Unless you have one of those cool “enhance” features that they have on CSI. OMG that drives me nuts. “Well we have this fuzzy phone image of the perp.” “Can you zoom in and enhance?” “Sure.” (Fuzzy image becomes crystal clear hd image of perps face.)

Where do we buy the csi zoom plugin?

Good try Gary but it’s only going to jump to 30 megs if you have “resample image” turned on. Which will also turn the image into a 4000×2667 image. Of course it’s going to be 30megs!

If you just want to change the dpi, you’ve got to have “resample image” turned off. Resampling the image is pretty much the same effect as FCP blowing up the image past 100%. It’s just being interpolated. Although Adobe does a much better job at it in PS or AE.
